Question

select the correct answer.
which verb form correctly completes this sentence?

mi hermana ______ a cocinar un pastel de chocolate.
a. debe
b. necesita
c. va
d. tienes

Explanation:

To solve this, we analyze each option:

• Option A: "debe" is "must/should", and "debe a" is incorrect usage (correct would be "debe + infinitive" without "a").
• Option B: "necesita" is "needs", and "necesita a" is incorrect (correct is "necesita + infinitive" without "a" in this context for "necesitar" meaning "need to do").
• Option C: "va" is from "ir" (to go), and "ir a + infinitive" means "to be going to do" or "to go to do". So "Mi hermana va a cocinar..." means "My sister is going to cook...", which is correct.
• Option D: "tienes" is "you have" (second - person singular), but the subject is "mi hermana" (third - person singular), so it's incorrect in both subject - verb agreement and meaning.

Answer:

C. va
