STRENGTHEN SET OFFICIAL EXPLANATIONS
Answer KEYSCDCBCCBDEC 6.
The director concludes that the fee hike has helped to counteract the cut in state
funding. In other words, the director believes that increasing the late fees has led
to increased revenue from late fees. While the size of the fee itself is one
important factor, there are other factors that also have an effect on the amount of
revenue generated from late fees: the number of overdue books and the number
of days that books are overdue before they are returned. It’s very possible that
the fee increase would prompt more borrowers to return their books on time; this
would reduce the number of late fees being paid, reducing revenue from late
fees. Further, it’s possible that the fee increase would prompt more borrowers to
return their already overdue books sooner than they would otherwise. This would
reduce the average amount of each late fee, reducing revenue from late fees.
The argument explicitly states that there has been no decline in the number of
overdue books, but it says nothing about the number of days that books are
overdue before they are returned. A statement that rules out the possibility that
borrowers are returning their already overdue books sooner than they would
have if they were still being charged the original lower overdue fee would
strengthen the director’s claim.
(A) A decrease in the number of borrowed books has no bearing on the revenue
generated from late fees if the number of overdue books remains unchanged.
The question explicitly states that the number of overdue books has not changed.
(B) If anything, this statement weakens the argument. The costs incurred to
implement the new fees would cut into the revenue generated from these new
fees.
(C) CORRECT. This statement rules out the possibility that the library system is
losing revenue as a result of borrowers returning overdue books earlier than they
would otherwise.
(D) The argument has explicitly stated that the number of overdue books has not
changed. This is a stated premise that we must take as factual information,
regardless of the quality of the database being used to track such information.
(E) The elimination of other unrelated costs has no bearing on whether the library
system has successfully increased revenues through late fees.
Please feel free to post particular question doubts, and I will be happy to clarify as much as I can.This states that The library knows as a fact that there is no decline in the no. of books over due. The claim by the director is that the increase in fees has helped them generate revenue.
I feel D is right as it supports his claim, meaning as the library has a advanced system to track the the overdue books, they can for certain say that the increase in revenue has negated the decrease in funds.
