Question

select the correct answer.
which word or phrase best completes this sentence about a rule?
______ registrar sus nombres en la recepción.
a. nunca
b. hay que
c. tampoco
d. no debe

Explanation:

To solve this, we analyze each option:

• Option A: "Nunca" (Never) would need a verb form like "nunca registrar" but the structure here is about a rule that requires an action, so "nunca" alone doesn't fit.
• Option B: "Hay que" means "it is necessary to" or "one must". The sentence structure "Hay que registrar sus nombres en la recepción" (One must register their names at the reception) makes sense for a rule.
• Option C: "Tampoco" (Neither/Not either) is used in negative contexts to add another negative action, which doesn't fit the rule - making context here.
• Option D: "No debe" (He/She should not) is singular, but the subject here is more general (implied "people" or "they"), and the rule is likely a positive obligation (to register) rather than a negative one.

Answer:

B. Hay que
