题目不太难。但是我不太懂为什么e选项不能够作为答案。
It is hard for students to get good grades in school. But the hardest problem met by students' parents is that the students do not want to get good grades, and even an eight-year-old child could take examples of "successful without good grades" people such as Steve Jacobs and Bill Gates to explain his bad grades.
To improve students' academic performance, education professor Roland Fryer decides to let students get paid on the basis of metrics such as attendance, behavior, tests, and class work.
Which of the following, if true, most seriously weakens the Roland Fryer's conclusion above?
C. Students who get paid from their parents may spend the payment on smoking and drinking.
E. Money is not always the best incentive for students to have good grades in school.
其他选项都容易排出 所以就不列出来了
我明白答案选c的逻辑, 但是在书中 对于e选项 helr说“无论金钱是不是最好的,只要是能达成目的且没有什么副作用的内容就能使本体的方案推理成立,所以本选项不符合方案推理的三个方向,排除”
所谓方案推理的三个方向是: 方案可行性:能否达成目标? 方案可操作性:方案能行么?能操作么?
和 方案的否定副作用:方案实现后 是否带来一些不好的副作用。
对于选项e 如果金钱无法成为incentive 那么学生可以就不会努力学习考好分数啊 这不是就是说 方案可能不成功么? 方案无法实施么?
请问大家怎么看?
