Question

what does the idiom in this text suggest? \speak of the devil!\ cara declared when brian strolled into the room. cara had just been speaking about brian. cara thought brian was a troublemaker.

Explanation:

The idiom "Speak of the devil" is used when the person you have just been talking about appears. In this context, Brian strolled into the room right after Cara might have been talking about him, so the first option makes sense. The second option has no basis as the idiom doesn't imply the person is a troublemaker.

Answer:

Cara had just been speaking about Brian.
