Your cover letter and resume should be no more than one page each.

a. True

b. False

I belleve it should only be one page each so I would go with A true

As a general rule, if your cover letter is more than one page, it is too long. Cover letters are supposed to be a summary (not an exhaustive list as that is what a resume is for) of your work history, some of the applicable skills you acquired on the previous jobs that will be useful on the job you are applying for, an expression of strong interest in the job being applied for, and a request for additional contact to discuss the job you are applying for. Consider that the person reading it will be reading your cover letter and resume along with, perhaps, 200 other people's resumes and cover letters. If they have to take too long to review yours, they aren't going to be able to review everybody else's in a timely manner. Try to keep your cover letter to one page as an absolute maximum.
