Complete the sentence: We must go to the store. We () go to the store.

• A. Have got to
• B. Must
• C. Should
• D. Need to

Answer: (A)

Expressing obligation with a varied phrase keeps the meaning intact while sounding natural. The pair uses a different way to express necessity: “have got to” functions like “must” but in a more informal, conversational style, so the completed sentence reads smoothly as a new statement with the same sense: “We have got to go to the store.” The other options would either repeat the exact word from the first sentence, soften the obligation, or express a slightly different nuance, which is less fitting for this parallel structure.
