Question

choose the word that best completes the sentence. the baby is asleep, so we should ______ when we talk. whisper whistle scream crawl

Explanation:

When a baby is asleep, we need to speak quietly to avoid waking them. "Whisper" means to speak very softly, which fits this context. "Whistle" is making a sound with the lips, "scream" is loud shouting, and "crawl" is a movement, none of which make sense here.

Answer:

whisper
