Question

marc blew a ______ to get everyone’s attention. whistle wrisper wlistle

Explanation:

First, analyze the context: the phrase "blew a ____" requires a noun that refers to an object you blow to make noise for attention. "Whistle" is the correctly spelled word for such an object. "Wrisper" is a misspelling of "whisper" (an action of speaking quietly, not blown), and "wlistle" is a misspelling of "whistle".

Answer:

whistle
