Hello, I encountered the following question in my CAT 4 and boiled it down to choices C and D. I picked D because I thought the administration would increase the amount of fines (i.e. now the ticket would be $500 vs. $100 before). The right answer is C because the question meant that the administration would be handing out more fines (or tickets). Could a staff instructor please clarify this question? Thank you!
