-<!-- (Audio) Mateo: Hola, buenas noches. Me llamo Mateo. Soy ingeniero de software. Soy puertorriqueño. Tengo 25 años.-->

 # --description--
 
-In this lesson, you will listen to Mateo's second version introduction in Spanish. We will practice profession-related words, nationality, and age in more detail in the next lessons.
+In the last Learn block, you practiced phrases for greeting someone, introducing yourself, your profession, nationality, age, and farewell at different times of the day.
 
-# --assignment--
+In this video, Mateo introduces again all these phrases. Listen carefully and pay attention to his pronunciation.
 
-Watch the video.
+# --instructions--

+Listen to the audio and answer the question below.
+
+# --questions--

+## --text--
+
+Which greeting is Mateo using to greet you?
+
+## --answers--
+
+`Buenos días`
+
+### --feedback--
+
+This greeting is used in the morning, not at night.
+
+---
+
+`Buenas tardes`
+
+### --feedback--
+

+
+---
+
+`Buenas noches`
+
+---
+
+`Hola, ¿qué tal?`
+
+### --feedback--
+
+This is a general greeting, but Mateo uses a more specific one for nighttime.
+
+## --video-solution--
+

+
+# --explanation--
+
+`Buenas noches` is the standard Spanish greeting used during the night. This is the greeting Mateo is using. 
+
+`Buenos días` is used in the morning, and `Buenas tardes` in the afternoon.
+
+`Hola, ¿qué tal?` is an informal way of saying "Hi, how are you?" at any time of day, but it does not specify time like `Buenas noches`.

+
+`Me llamo Mateo` means "My name is Mateo", literally "I call myself Mateo".  
+
+It’s a common and natural way to introduce yourself in Spanish.
+
+Other valid options are `Soy Mateo` and `Mi nombre es Mateo`, but Mateo uses the `llamarse` reflexive verb form.

+
+This word completes a common farewell phrase meaning you'll see someone the next day.
+
+# --explanation--
+
+`Estratega` fits the phrase `estratega de marketing`, describing Julieta’s profession. 
+
+`Uruguaya` is the feminine nationality adjective that matches Julieta’s origin.

+`Treinta y seis` corresponds to Julieta’s stated age.  
+
+`Mañana` finishes the farewell `Hasta mañana`.

+
+### Conjugation of `tener` in Present Indicative Tense
+
+The verb `tener` (to have) is commonly used to talk about **age** in Spanish. Instead of saying "I am 28 years old," you say "I have 28 years."
+
+| Person               | Conjugation | English Meaning         |
+|----------------------|-------------|--------------------------|
+| `yo tengo`           | `tengo`     | I have / I am (age)     |
+| `tú tienes`          | `tienes`    | you have (informal)     |
+| `él/ella tiene`      | `tiene`     | he/she has              |
+| `nosotros/as tenemos`| `tenemos`   | we have                 |
+| `ellos/as tienen`    | `tienen`    | they have               |
+
+Examples:
+
+- `Tengo veintiocho años.` – I am 28 years old.
+
+- `Tengo treinta y seis años.` – I am 36 years old.
+
+---
+
+### Nationalities and Gender Agreement
+
+In Spanish, nationalities must agree in gender with the person they're describing:
+
+- Masculine nationalities often end in `-o` or a consonant.
+- Feminine forms often end in `-a`.
+
+Examples:
+
+- `Soy chilena.` – I am Chilean (feminine).  
+- `Soy puertorriqueño.` – I am Puerto Rican (masculine).  
+- `Soy uruguaya.` – I am Uruguayan (feminine).
+
+---
+
+### Greetings by Time of Day
+
+Spanish greetings change depending on the time of day:
+
+- `Buenos días` – Good morning
+- `Buenas tardes` – Good afternoon
+- `Buenas noches` – Good evening/night
+
+These are polite and time-sensitive ways to start a conversation.
+
+---
+
+### Farewells
+
+Here are some common ways to say goodbye in Spanish:
+
+- `Adiós` – Goodbye
+- `Hasta luego` – See you later
+- `Hasta pronto` – See you soon
+- `Hasta mañana` – See you tomorrow
+- `Chau` – Bye (informal)
