Question

john and i always seem to bite off more than we can chew. we are worried about finishing and do not want to have to ______.
hold our tongues
throw in the towel
see eye to eye

Explanation:

First, we analyze the meaning of each idiom:

• "hold our tongues" means to keep silent, which doesn't fit the context of being worried about finishing a task.
• "throw in the towel" means to give up, and since John and I took on more than we can handle and are worried about finishing, we don't want to give up, so this idiom fits the context.
• "see eye to eye" means to agree with someone, which is not related to the context of completing a task.

Answer:

B. throw in the towel
