Which sentence contains an error in punctuation?
Tyrek, did you sign the birthday card?
The treadmill, was in excellent condition.
o
We finally found the perfect gift, a treadmill
Francine, after finding her pen, signed the card.

The treadmill, was in excellent condition contains the error. You don't need the comma.

explanation:

you only need simple sentences to answer this. just answer these questions.

what do you think annie thinks of the mother? do you think annie believes the mother is a fit mother for helen.

what about the father? what would annie think of him? she might not like him, but does she respect him.

how about the son? would annie think he is the only voice of sanity in an insane place?

what about helen herself? this is the key question. how does she see helen? what do you suppose she thought her first job was going to be.

these aren't hard questions. just state the obvious. annie is not that well educated: she just knows what she has to do. write it that way.

you can do it if you've read the book or seen the play or movie.
