1) Correct answer:
Yo iré a la tienda porque necesito algo
We use the Spanish simple future to talk about what will or shall happen. It is also used to talk about the possibility of what someone may or might be doing in the present. The original sentence stands for the first person singular in the simple present. So voy is the conjugation of the verb ir in this tense. To change this sentence from the simple present to the simple future, we must change the word voy to iré.
2) Explanation:
We have two questions:
¿Cuál manzana te gusta más? that means which apple do you like the most? and ¿desde cuándo nadas? that means since when have you been swimming? So we can answer these two questions in Spanish as follows:
¿Cuál manzana te gusta más?
Me gusta más la manzana verde
¿Desde cuándo nadas?
Nado desde hace 3 años
3) Explanation:
We use the imperative mood when telling someone to do something in a direct manner. Put another way, sentences in the imperative mood are commands. So we need to change three sentences from the simple present to the imperative mood. So:
Tú eres simpático:
In the imperative mood: Sé simpático (be nice)
Me lo das:
In the imperative mood: Dámelo (give it to me)
Uds. se despiertan:
In the imperative mood: Despiértense (Wake up)
4) Correct answer:
cuál
¿cuál? and ¿cuáles? are typically the equivalent of which? in English. These are used if there is a choice between two or more things. Since you need to choose one day, that is, a singular noun, then we use the interrogative pronoun cuál. Therefore, this might be the dialogue:
¿Cuál de los días es preferible para ti?
Yo prefiero los viernes
