【正确答案】 C

【答案解析】本题较为容易，在独白第六句中明确出现了题目中所出现的engineering一词：Our science and engineering sections can be found on level three，因此本题答案就是[C]。

【正确答案】 B

【答案解析】本题需要考生在听清、听懂原文的基础上进行计算。独白倒数第三句提到了借书过期不还的惩罚性措施：There is a 50-cent-a-day late fee for overdue books up to 3 maximum of$15.00，即每天收费50美分．但最高不超过15美元。而题目限定的条件是过期40天，按每天50美分来算．应当是20美元，显然超过了15美元，因此在这种情况下就只需要支付最高上限15美元了，故答案是[B]。
