Question

Identify the problem with the following sentence. As Karen drove her Mustang up to the take-out window, it began to rattle

Answer 1

it makes it sound like the window is beginning to rattle. if this is multiple choice, the answer is unclear meaning.

Answer 2

in other words, it's not clear what the "it" is modifying - mustang is the subject of the sentence and 'it' obviously should clearly modify the subject. can you re-write it so that it's more clear?
