In this exercise, we have six sentences. The verbs in parentheses need to be conjugated in the simple present tense. This tense is used to talk about habitual actions or routines. This tense is also used to describe things that happen now or in the near future. Therefore:
1. Right conjugation:
empieza
Empieza is the conjugation of the verb empezar that matches the third person singular (because Sofía can be replaced by the subject pronoun that matches the third person singular in feminine form, which is ella) in the simple present. Finally we can write and translates this sentence as follows:
Sofía empieza a ver una película (Sofia starts watching a movie)
2. Right conjugation:
juegan
Juegan is the conjugation of the verb jugar that matches the third person plural (because los Pumas can be replaced by the subject pronoun that matches the third person plural, which is ellos) in the simple present. Finally we can write and translates this sentence as follows:
Los Pumas de la UNAM juegan en el estadio (The Pumas of the UNAM play in the stadium)
3. Right conjugation:
pide
Pide is the conjugation of the verb pedir that matches the third person singular (because el jugador can be replaced by the subject pronoun that matches the third person plural in masculine form, which is él) in the simple present. Finally we can write and translates this sentence as follows:
El jugador pide una pelota de tenis (The player asks for a tennis ball)
4. Right conjugation:
oye
Oye is the conjugation of the verb oír that matches the third person singular (because Mariana can be replaced by the subject pronoun that matches the third person plural in feminine form, which is ella) in the simple present. So oír is an irregular verb. Finally:
Mariana oye la radio por la tarde (Mariana listens to the radio in the afternoon)
5. Right conjugation:
preferimos
Preferimos is the conjugation of the verb preferir that matches the first person plural (because César y yo can be replaced by the subject pronoun that matches the first person plural in masculine form, which is nosotros) in the simple present. So preferir is an irregular verb. Finally:
César y yo preferimos jugar al vóleibol (Cesar and I prefer to play volleyball)
6. Right conjugation:
sigues
Sigues is the conjugation of the verb seguir that matches the second person singular, which is tú, in the simple present. We use tú when addressing someone in an informal way. On the other hand, seguir is an irregular verb. Finally we can write and translates this sentence as follows:
Tú sigues el partido por la radio (You follow the game on the radio)
