Question

select the correct answer.
which word best completes the sentence?
en los restaurantes de ecuador, la gente ______ fumar en el exterior.
a. necesario
b. ni
c. siempre
d. debe

Explanation:

To solve this, we analyze each option:

• Option A: "necesario" is an adjective, and the sentence structure requires a verb (or a modal verb - like structure) to connect the subject "la gente" with the infinitive "fumar". So it doesn't fit.
• Option B: "ni" is a conjunction used in negative constructions (like "ni...ni..."), and it can't be used here to form a meaningful sentence with "fumar".
• Option C: "siempre" is an adverb, and we need a verb - related element to link the subject and the infinitive. An adverb alone can't do that.
• Option D: "debe" is a modal verb (from "deber") that means "must/has to", and it can be followed by an infinitive ("fumar"). The sentence would mean "In Ecuadorian restaurants, people must smoke outside", which makes sense in the context of smoking regulations.

Answer:

D. debe
