本人是新手，问道狒狒里的例题～～～

“On the whole,” Ms. Dennis remarked, “engineering students are lazier now that they used to be. I

know because fewer and fewer of my students regularly do the work they are assigned.”

  The conclusion drawn above depends on which of the following assumptions?

(A) Engineering students are working less because, in a booming market they are spending more and

more time investigating different job opportunities.

(B) Whether or not students do the work they are assigned is a good indication of how lazy they are.

(C) Engineering students should work harder than students in less demanding fields.

(D) Ms. Dennis’ students are doing less work because Ms. Dennis is not as effective a teacher as she

once was.

(E) Laziness is something most people do not outgrow.

大家觉得应该选那个选项呢？

个人感觉是B,不知对否

因为对B答案取非,假设学生做不做作业不能够说明他们是不是懒惰,那题目中 Ms. Dennis 的remark就是没有道理的

94b 取非
