<!-- (Audio) Sophie: Hey, Tom, have you heard about Artificial Intelligence? -->
# --description--
`Artificial Intelligence` is like teaching a computer to think and learn on its own. It's like giving a robot a brain to make decisions. `Artificial Intelligence` helps computers understand things, learn from experiences, and solve problems, just like humans.
# --question--
## --text--
What is the definition of `Artificial Intelligence`?
## --answers--
Random tools that create magic
### --feedback--
`Random tools that create magic` doesn't define Artificial Intelligence; it's about computer systems, not tools.
---
Books that contain secret knowledge
### --feedback--
`Books that contain secret knowledge` is not a definition of Artificial Intelligence; it's about computer intelligence.
---
Smart computer system that can learn and solve problems
---
Pictures that use various colors for creativity
### --feedback--
`Pictures that use various colors for creativity` is unrelated to the concept of Artificial Intelligence. Choose the definition that fits with a smart computer system.

<!-- (Audio) Tom: Well, AI is everywhere, from chatbots that help with customer service to self-driving cars that use AI to navigate safely. -->
# --description--
In English, the phrase `from... to…` is used to show a range or a journey between two points or values. It indicates where something starts from one point and ends at another.
For example, if you say, `I work from Monday to Friday`, it means your workdays are from Monday (the starting point) to Friday (the ending point). It's a way of expressing the entire span between two specific things or times.
In simpler terms, `from... to…` helps you talk about the beginning and ending parts of something, like a time period, a place, or a range of numbers.
Complete the sentence with the correct phrase.

<!-- (audio) Sophie: Wow, that's incredible! But what about ethical concerns? -->
# --description--
`Ethical concerns` are like moral questions we ask ourselves about what is right and wrong. In everyday life, we think about what is fair, honest, and kind. In the world of programming, `ethical concerns` are the moral decisions and worries that programmers have about the impact of their work on people and society. For example, programmers need to think about user privacy, fairness, and safety when creating software.
Examples: `Programmers need to consider ethical concerns in their work.`
`When you have ethical concerns, you think about the impact of the content on users and society.`
Listen to the audio and complete the sentence.

# --description--
`Ethical` and `ethically` both refer to doing things that are morally right and fair. `ethical` is an adjective used to describe something that is right or good according to moral principles. On the other hand, `ethically` is an adverb that describes how something is done in a moral or fair way, indicating the manner in which an action is performed.
In English, both adjectives and adverbs are used to provide more information about verbs, adjectives, or other adverbs in a sentence. However, they serve different roles:
`Adjectives` are words that describe or modify nouns (people, places, things, or ideas). They provide more information about the noun, giving details such as size, color, shape, or emotion. For example, in the phrase `a green apple`, the word `green` is an adjective because it describes the noun "apple."
`Adverbs`, on the other hand, are words that modify verbs, adjectives, or other adverbs. They provide information about how an action is done, when it happened, where it happened, or to what extent. Adverbs often end in `-ly`, but not always. For example, in the phrase `She sings elegantly`, the word `elegantly` is an adverb because it describes how the action of singing is done.
Read the sentence and fill in the blanks with the correct term: `ethical` or `ethically`.
# --fillInTheBlank--
## --sentence--
`Programmers must consider the _ implications of their code, ensuring they behave _ while developing software.`
## --blanks--
`ethical`
### --feedback--
In this case, we are using a quality to describe `implications`. Use the adjective instead.
---
`ethically`

In this case, we are mentioning how someone should behave. Use the adverb instead.

<!-- (Audio) Tom: But researchers and companies are actively working on addressing these issues. -->
# --description--
`Active` and `actively` both relate to doing something, but in slightly different ways. `Active` is an adjective indicating a state of being, describing something that is happening right now, and something that is always busy or lively. For example, if someone is active, it means they are always doing things and not just sitting still. `Actively`, as the corresponding adverb, is about doing something with energy or effort. It shows how an action is done.
Listen to the audio and fill in the blank with the correct form: `active` or `actively`.
# --fillInTheBlank--

For instance, if you talk about fruit like apples, bananas, and oranges, you are giving examples of different fruit. `like` helps you show what you mean by giving specific names or things related to the topic. Example: `My son loves eating different kinds of fruit like apples, bananas, and oranges.`
# --question--
## --text--
Which of the following best describes the use of `like` in this sentence:
`Languages like Python, Java, and C++ are widely used in software development.`
## --answers--
To express preference for a programming language
### --feedback--
Express preference means stating what you like or prefer. The sentence is providing examples, not preferences.
---
To indicate similarity between programming languages
### --feedback--
Indicate similarity means showing how things are similar, not listing specific examples.
---
To introduce specific examples of programming languages
---
To describe emotions related to coding
### --feedback--

<!-- (Audio) Alice: Video conferencing tools also made it possible for teams to have face-to-face meetings online. -->
# --description--
`Video conferencing` is a way to have meetings or conversations with people who are not in the same location as you. Instead of talking on the phone, you use a special program or app on your computer, tablet, or phone. This program allows you to see and hear the other person on your screen, almost like they are in the same room with you, even if they are far away. It's a helpful tool for talking to friends, family, or colleagues when you can't meet in person.
Listen and fill in the blanks.
# --fillInTheBlank--
## --sentence--
`_ _ tools also made it possible for teams to have face-to-face meetings online.`
## --blanks--
`Video`
### --feedback--
We say this of things like apps or programs that give us a visual of what is happening. It is capitalized as it is the beginning of a sentence.
---
`conferencing`
### --feedback--
This word refers to the fact that many people can join the same event. Preceeded by `video`, it means everyone can see each other.

<!-- (Audio) Alice: Video conferencing tools also made it possible for teams to have face-to-face meetings online. -->
# --description--
`Face-to-face` means you and someone else can see each other directly. It's like having a conversation with a friend or a teacher when you can see their face and they can see yours.
Example: `Even though we are in different countries, we can still have face-to-face meetings online using video conferencing tools.`
# --question--
## --text--
According to Alice, what kinds of meetings do video conferencing tools allow you to have?
## --answers--
Meetings where people send text messages to each other
### --feedback--
This option involves text messages and doesn't include real-time conversation with video.
---
Meetings where people share documents without speaking
### --feedback--
Sharing documents is part of online collaboration, but it doesn't define a face-to-face meeting.
---
Meetings where people write letters to each other
### --feedback--
Writing letters is a traditional way of communication and not the same as real-time online interaction.
---
Meetings where people talk and see each other through the computer or phone

<!-- (Audio) Alice: Remote work is likely to remain a big part of our lives. It offers flexibility and can help companies gain access to talent from many parts of the world. -->
# --description--
`Gain access to` means to be able to use something or go somewhere that you couldn't before. It's like being given permission to enter a room or use a computer. In the dialogue, Alice means that companies can now work with talented people of different parts of the world, thanks to remote work.
# --question--
## --text--
According to Alice, what is helping companies to have talented workers from all the world working for them?
## --answers--
The companies are paying for these workers' travel expenses
### --feedback--
Not exactly. They don't have to travel to another location because of remote work.
---
Seminars and conferences in the company's own country
### --feedback--
Even though these events tend to have people from all over the world, that is not what Alice says.
---
Having branches in these workers' countries
### --feedback--
Multinational companies can do that, but there are other ways to have people from other countries working for you now.

# --description--
When you say something `is likely to`, it means something is expected or probable to happen. It indicates a high chance that a particular action will occur in the future. For example, if a certain programming language is easy to use, you might say it is likely to remain popular, meaning it will probably stay popular in the future.
In English, you can use verbs with the word `to` before them to talk about different actions. For example, `to eat`, `to run`, or `to learn`. When you talk about something that needs to happen or might happen in the future, you use this structure. For instance, `I want to eat`, `She likes to run`, or `They need to learn`.
So, `to + infinitive` is a way you express actions that could or should occur, often indicating plans, desires, or possibilities.
# --question--
## --text--
What does `Python is likely to remain popular` mean?
## --answers--
Python will disappear soon.
### --feedback--
`Likely to remain` suggests a prediction about the future, not disappearance.
---
Python will be popular for a short time.
### --feedback--
`Likely to remain` implies a lasting popularity, not just a short-lived trend.
---
Python is expected to continue being popular.
---
Python will only be used by a few people.
### --feedback--
`Likely to remain` indicates that Python will continue to be widely used, not limited to a few users.

<!-- (Audio) Alice: Well, there are project management tools. They help teams to organize tasks. -->
# --description--
`To help someone to do something` means assisting someone in doing a specific action. It involves giving support or guidance to enable them to complete a task or achieve a goal. Some sentences before, Alice says `It offers flexibility and can help companies gain access to talent from many parts of the world.` Notice that, in this sentence, she does not use `to` before `gain`, since using both the `infinitive` form and the `to + infinitive` are possible.
Listen to the audio and fill in the blanks.
# --fillInTheBlank--
## --sentence--
`Well, there are project management tools. They _ teams _ organize tasks.`
## --blanks--
`help`
### --feedback--
A verb that means the same as providing assistance.

<!-- (Audio) James: Sarah, have you heard about Quantum Computing? -->
# --description--
This challenge is a quick refresher to the **Present Perfect** structure. Remember that, in order to talk about situations that happened in an undetermined moment in the past (when it occurred in the past is not important, only the event matters), it is common to use the Present Perfect structure instead of a *Simple Past* structure to talk about it.
Examples:
`Did you see him last week?` (I am asking if you saw another person in a specific moment in time - `last week` - use the Simple Past).
`Have you seen him?` (I'm asking if you saw the person, regardless of when it happened - use the Present Perfect).
In this question, James is asking Sarah if she has heard about a specific type of computing, no matter when it happened.
Fill in the blanks with the appropriate words.
# --fillInTheBlank--
## --sentence--
`Sarah, _ you _ about Quantum Computing?`
## --blanks--
`have`
### --feedback--
The auxiliary verb for the Present Perfect structure.
---
`heard`
### --feedback--
The verb `hear`, but in the participle form, to fit the Present Perfect structure.

<!-- (Audio) James: Sarah, have you heard about Quantum Computing? I just heard about it for the first time. -->
# --description--
Sometimes, it is possible that a verb in the Simple Past and in the Present Perfect are conjugated the same way. In this dialogue, James asks if Sarah `has heard` about Quantum Computing and then says he just `heard` about it. The participle form of `hear` is `heard`, just like the past form of `hear` is `heard` as well. Examples: `On Monday, I heard you were coming to visit.` (someone told me this on Monday). `I have heard about the situation before.` (there is no reference as to when). In both cases, `heard` is used. James says he `just heard` about Quantum Computing, meaning it happened a short time ago, probably minutes before the conversation. `Just` is used here to express that something happened a bit before the moment the conversation is happening. Example: `I just saw him crossing the street.`
Listen to the dialogue and fill in the blanks.
# --fillInTheBlank--
## --sentence--
`Sarah, have you heard about Quantum Computing? I _ _ about it for the first time.`
## --blanks--
`just`
### --feedback--
This word is used to mean that something happened a bit before this conversation.
---
`heard`
### --feedback--
This is the verb `hear` in the Simple Past form. You write it the same way as the participle form of `hear`.

<!-- (Audio) James: Sarah, have you heard about Quantum Computing? I just heard about it for the first time. Are you familiar with it? -->
# --description--
`To be familiar` with something is to know at least a bit about the topic. If you ask someone `are you familiar with this?`, you are asking them if they know it. Example: `I have never seen this soda before. It's delicious. Are you familiar with it?` (you are asking if the person knows and/or tasted that soda before).
# --question--
## --text--
What is James asking Sarah?
## --answers--
If Sarah knows how to use computers
### --feedback--
James knows Sarah is a developer. That's not what he's asking.
---
If Sarah has any plans for the weekend
### --feedback--
The discussion is not about what they are going to do on the weekend.
---
If Sarah knows about Quantum Computing
---
If Sarah heard it when his computer broke
### --feedback--
There's no mention of a broken computer in the scene.

<!-- (Audio) Sarah: I know a little. Quantum Computing uses special computers to perform calculations extremely quickly. -->
# --description--
When you use `a little`, you mean the same as `some`, a small quantity or amount. It is the opposite of `a lot`. Example: `I know a little about Chemistry.` (meaning you understand some of it, but you are not necessarily an expert).
`Perform` means to do something, like a task or an action. When you perform, you're showing what you can do or completing a job or activity. When singing a song on a stage, solving a math problem, or playing a game, you are `performing`.
Listen to the dialogue and fill in the blanks.
# --fillInTheBlank--
## --sentence--
`I know a _. Quantum Computing uses special computers to _ calculations extremely quickly.`
## --blanks--
`little`
### --feedback--
Combined with `a` before it, it means a small amount, not much.
---
`perform`
### --feedback--
Do something, like singing, dancing, or solving an equation.

<!-- (Audio) Sarah: I know a little. Quantum Computing uses special computers to perform calculations extremely quickly. -->
# --description--
Normally, what differentiates an adjective from an adverb is the suffix `-ly` in the end, added to an adjective to create an adverb. Examples: `extreme` (adjective) x `extremely` (adverb) / `quick` (adjective) x `quickly` (adverb).
Also, know that it is possible to use an adverb like `extremely` to intensify an adjective or even another adverb. If you say that something happens `quickly`, it is a fast action. If it is `extremely quickly`, the action is super fast.
Fill in the blanks according to what Sarah says in the dialogue.
# --fillInTheBlank--

`I know a little. Quantum Computing uses special computers to perform calculations _ _.`
## --blanks--

<!-- (Audio) James: That's cool. But what can it do besides calculating things? Sarah: Well, it's not just for one thing. -->
# --description--
When asking Sarah about quantum computers, James wants to know if calculating things is the only purpose they have. Sarah disagrees. She says `Well, it's not just for one thing.` In this context, `just` means the same as `only`, as in `it's not the only thing quantum computers can do`.
In the beginning of the dialogue, James uses `just` to say he heard about quantum computers moments before their conversation. This is another usage for `just`.
# --question--
## --text--
What conclusion can we get from Sarah's answer?
## --answers--
Quantum computers can do more than simply calculating
---
Quantum computers are a calculation device and that is all they can do
### --feedback--
According to Sarah, they don't serve only for calculating.
---
Quantum computers can't calculate
### --feedback--
According to Sarah they can, but it is not their only purpose.
---
Sometimes, quantum computers produce wrong results

<!-- (Audio) Sarah: Quantum computers can also help scientists with research. -->
# --description--
A `scientist` is someone who studies and learns about nature and the world. They ask questions and try to find answers.
`Research` means trying to find more information about something. You might do research by reading books, looking online, or testing to learn new things. When you talk about `scientific research`, it normally involves a more formal setting, with regulated conditions.
The word `also` can be used in substitution to `too` and can be added in different places in a sentence. Examples: `He can play the guitar, but he plays the piano, too.` (`too` is normally added in the end of the sentence, preceded by a comma). `He can play the guitar, but he can also play the piano` (you can add `also` before the verb and in the middle of the sentence). These two sentences mean the same.
# --fillInTheBlank--
## --sentence--
`Quantum computers can _ help _ with _.`
## --blanks--
`also`
### --feedback--
This word means the same as `too`, but can be used in other positions in the sentence.
---
`scientists`
### --feedback--
People who study nature and the world, normally in more strict conditions. Use the plural form.
---
`research`
### --feedback--
This word means trying to find information about something.

<!-- (Audio) Sarah: They're useful for studying things like molecules and drugs. -->
# --description--
When you say something is `useful`, you mean it can help you to perform a certain task or activity. Example: `Computers are very useful for calculating things.` As you can see, after `useful`, we have the preposition `for`, meaning any verb that comes after it has to be in the `-ing` form (see the example).
`Molecules` are like tiny building blocks that make up everything. Everything you see and touch is made from molecules. They are groups of two or more atoms together.
`Drugs` are substances that change how our bodies feel or work. There are two kinds: medicine and illegal drugs. People can take drugs as pills, liquids, or in other ways.
Fill in the blanks with the correct word from the dialogue.
# --fillInTheBlank--

`They're _ for _ things like _ and _.`
## --blanks--
`useful`
### --feedback--
Something that can help you perform a task.
---
`studying`
### --feedback--
The act of spending time learning something. Since it is preceded by `for`, it goes in the `-ing` form here.
---
`molecules`
### --feedback--
Groups of two or more atoms together. Very small parts of everything. Use the plural form here.

Substances that can change the way your body acts or feels. They can be legal or illegal. Use the plural form here.

<!-- (Audio) James: Wow, that's amazing. Is it hard to understand how quantum computers work? -->
# --description--
When you combine `it is` followed by an adjective (like `hard`, `easy`, `simple` and others), a verb that comes after this combination has to be in the `to + infinitive` form. Example: `It is easy to study for English tests.` (after the adjective, `easy`, you have to use `to` before `study`). In a question, invert `it` and `is`. Example: `Is it simple to learn to play an instrument?`
Listen to the audio and fill in the blanks with the correct words.
# --fillInTheBlank--
## --sentence--
`Wow, that's amazing. Is it _ to understand how quantum computers _?`
## --blanks--
`hard`
### --feedback--
In this context, it means the same as `difficult`.
---
`work`
### --feedback--
In this context, it is the same as `operate` or `function`. It is also used to talk about tasks you do at your job.

<!-- (Audio) Sarah: They may seem complicated, but there are lots of simple videos that can help you understand the basic ideas. -->
# --description--
You use `may` before a verb to say that there is a strong probability that it will happen. Look at the examples: `It is very easy.` (verb `to be` by itself - you are affirming something is very easy). `It may be very easy` (`may` comes before the verb to be - conjugated in the infinitive form without `to` - to say there is a strong probability that something is very easy, but you are not affirming it is).
`Lots of` indicate a great quantity/amount of something. Example: `I have lots of files in my laptop.` (there are many files there).

# --description--
A `basic idea` is the most important part of something, generally a simple one. It's what you need to understand first before learning more details.
# --question--
## --text--
What can you understand from Sarah's answer?
## --answers--
Quantum computers are complicated and you can't understand them
### --feedback--
That's not true. She even gives a suggestion on how to learn about them.
---
All you can learn about quantum computing is in videos on the internet
### --feedback--
Not really. She mentions videos to say they can help you understand the basics.
---
You can get started on learning about quantum computing by watching simple videos on the internet
---
If you make videos about quantum computing, you will learn a lot about them
### --feedback--
Sarah doesn't suggest that James make videos. She suggests that he watch some simple videos to start studying about them.

<!-- (Audio) James: Is it hard to understand how quantum computers work? Sarah: They may seem complicated, but there are lots of simple videos that can help you understand the basic ideas. -->
# --description--
Remember: if you don't want to affirm something - maybe because you are not 100% sure that it is true - you can soften the sentence by using `may` before the verb. Instead of saying `she is faster than you`, you can say `she may be faster than you`. This makes it sound like a strong probability, not something you know it is correct.
# --question--
## --text--
Why is James asking Sarah if quantum computers are hard to understand?
## --answers--
Because he wants to buy a quantum computer
### --feedback--
You don't know that for sure. He may want something different.
---
He just wanted a topic so he could talk to Sarah
### --feedback--
If you don't know the context, it is best not to affirm something as being 100% sure.
---
He may be curious about quantum computers and he may want to learn more about them
---
He wants to invent a new medicine or study molecules and drugs
### --feedback--
He may want that, but that is not necessarily true. We can't be 100% sure of that.

# --description--
In casual English, the phrase `what's the deal` is used to ask about a situation or to find out more information about something. It's like saying, `Can you tell me more about this?` or `What's going on with this?` It's an informal way of asking for an explanation or details.
# --question--
## --text--
What question could you ask to get information about something in a casual way?
## --answers--
`What's the issue with...?`
### --feedback--
The word `issue` suggests a problem, but Tom is asking for information, not indicating a problem.
---
`What's the deal with...?`
---
`What's the problem with...`
### --feedback--
`Problem` is similar to `issue`, and Tom is more curious than concerned.
---
`What's the news?`
### --feedback--
`News` doesn't fit the context of asking for an explanation about biometrics.

# --description--
`Fingerprint scanning` is a technology that looks at the unique patterns on your fingers to identify and verify who you are. It's like your fingers have special marks that are different from everyone else's. When you use `fingerprint scanning`, the system checks these marks to make sure it's really you. Just like `facial recognition`, it is an important technique used by `biometrics`.

The word `of` is a preposition that often indicates a relationship between two things. It is used to show possession, belonging, or connection. For example, in the phrase `the color of the sky`, `of` tells us that the color belongs to or is associated with the sky. Similarly, in the context of the phrase `the world of biometrics`, `of` signifies a connection or belonging between the world and the concept of biometrics.

<!-- (Audio) Alice: It's used for access control, like unlocking your phone with your face or fingerprint. -->
# --description--
`Access control` is like having a special key or permission to enter specific places or use certain things. It's a way of deciding who is allowed and who is not. In everyday terms, it's similar to how you might need a key to enter your house – only those with the right key (authorization) can get in.
# --question--
## --text--
Choose the correct description of `access control`.
## --answers--
Allowing anyone to enter
### --feedback--
`Access control` is about regulating and deciding, not allowing all the people.
---
Deciding who can enter or use certain things
---
Controlling the weather
### --feedback--
`Access control` is not related to controlling the weather.
---
Keeping doors closed
### --feedback--
`Access control` is not just about keeping doors closed. It involves deciding who can enter.

<!-- (Audio) Alice: For example, they're experimenting with palm vein recognition and even behavioral biometrics, like typing patterns to enhance security. -->
# --description--
`Palm vein recognition` is a technology that identifies individuals based on the unique patterns of veins in their palms. It involves capturing and analyzing the vein patterns, which are distinctive for each person, providing a secure method of authentication.
`Behavioral biometrics` means studying and using unique behaviors as a way to identify and verify individuals. It includes things like how you type, how you move, or other distinctive actions that are specific to you.
# --question--
## --text--
What innovations are researchers experimenting with in biometrics these days?
## --answers--
Measuring the temperature of palms and biometrics related to a persons behavior.
### --feedback--
It does not have to do with the temperature of palms, but with the pattern of veins in the palm.
---
The pattern of veins in a person's palm and their eating habits.
### --feedback--
`Behavioral biometrics` could study eating habits, but that's not all it studies.
---
The size of someone's palm and the way someone moves their legs.
### --feedback--
The palm vein recognition check is not about the size of one's palm. The way someone moves their legs is only a part of their behavior.
---
Palm vein recognition and behavioral biometrics.

# --description--
`Typing patterns` refers to the unique way you type on a keyboard or device. It includes the speed, rhythm, and specific patterns you use when pressing keys. Each person has their own distinct way of typing.
# --question--
## --text--
What is the relationship between `behavioral biometrics` and `typing patterns` based on the dialogue?
## --answers--
They are unrelated concepts.
### --feedback--
The dialogue suggests a connection between behavioral biometrics and typing patterns.
---
Behavioral biometrics is the same as typing patterns.
### --feedback--
While related, behavioral biometrics encompasses more than just typing patterns.
---
Typing patterns are a part of behavioral biometrics.
---
Palm vein recognition excludes the study of typing patterns.
### --feedback--
Palm vein recognition is mentioned separately and doesn't exclude the study of typing patterns in behavioral biometrics.

<!-- (Audio) Alice: For example, they're experimenting with palm vein recognition and even behavioral biometrics, like typing patterns to enhance security. -->
# --description--
`To enhance security` means making something safer or more protected. In the context of biometrics, using techniques like palm vein recognition and behavioral biometrics helps make security systems more effective and less vulnerable to unauthorized access.
# --question--
## --text--
What specific measures can be taken to enhance security in biometrics?
## --answers--
Implementing palm vein recognition
---
Decreasing security measures
### --feedback--
Decreasing security measures is the opposite of enhancing security.
---
Maintaining the current security protocols
### --feedback--
Maintaining the current security protocols may not necessarily involve making it better.
---
Avoiding the use of behavioral biometrics
### --feedback--
Avoiding the use of behavioral biometrics is a negation of a potential enhancement measure.

`Interior design` is like giving a special touch to the insides of buildings, especially your home. It's about making rooms look nice and feel comfortable. Imagine picking colors for your walls, arranging furniture in a cozy way, and adding decorations to make a room feel just right. When Tom mentions in the dialogue that you can use Augmented Reality (AR) for interior design, he means you can use technology to help imagine how furniture and colors might look in your space before actually putting them there.
# --question--

---
Designing the outside of buildings
### --feedback--
`Interior` refers to the inside of buildings, not the outside.

<!-- (Audio) Sophie: How does it work exactly? Tom: AR apps use your device's camera to add digital content to the physical world. It's so cool. -->
# --description--
When you add `'s` after a noun, it shows that something belongs to or is connected to that noun. It's like adding a label to say that this thing belongs to this person or object. `'s` indicates the ownership or possession.
Examples: `This is Tom's camera.` (this camera belongs to Tom). `That's today's newspaper.` (that newspaper has the news for today).
# --question--
## --text--
In the dialogue, what does Tom mean when he says `AR apps use your device's camera`?
## --answers--
That the camera belongs to your friend.
### --feedback--
Adding `'s` doesn't indicate that the camera belongs to a person necessarily.
---
That it is the camera on your device.
---
That the camera belongs to Tom.
### --feedback--
`'s` can be used to show possession, but not in this context.
---
That the camera belongs to Sophie.
### --feedback--
Sophie is not mentioned as the owner of the camera in this context. Think about the device mentioned.

<!-- (Audio) Tom: For example, in gaming, you can chase virtual creatures in your neighborhood. -->
# --description--
`To chase` means runing after or pursuing something, like trying to catch it or reach it. Imagine playing a game where you try to catch a moving object or follow it excitedly — that's what `chase` indicates.
# --question--
## --text--
What does `chase` mean in the context of AR gaming?
## --answers--
To avoid virtual creatures
### --feedback--
`To chase` implies active pursuit, not avoidance.
---
To run after or pursue virtual creatures
---
To replace virtual creatures
### --feedback--
The term involves interacting with virtual creatures, not replacing them.
---
To capture virtual creatures
### --feedback--
Although in some games you can capture virtual creatures, this has to do with running after them.
