Question

select the correct answer.
which verb form correctly completes this sentence?
cristina y ricardo ______ lavar los platos.
a. van
b. deben
c. necesita
d. tiene que

Explanation:

1. Analyze the subject: "Cristina y Ricardo" is a plural subject (two people), so we need a verb form that agrees with a plural subject.
2. Analyze each option:

• Option A: "van" is the third - person plural of "ir" (to go), and "ir a + infinitive" means "to be going to do". But "van lavar" is incorrect grammar; it should be "van a lavar".
• Option B: "deben" is the third - person plural of "deber" (to have to/should). "deben lavar" means "they have to wash" (grammatically correct as "deber" can be followed by an infinitive directly in the sense of "to have to do something").
• Option C: "necesita" is the third - person singular of "necesitar" (to need). Since the subject is plural, this is incorrect.
• Option D: "tiene que" is the third - person singular of "tener que" (to have to). The subject is plural, so this is incorrect (the correct plural form would be "tienen que").

Answer:

B. deben
