Cheever College offers several online courses via remote computer connection, in addition to traditional classroom-based courses. A study of student performance at Cheever found that, overall, the average student grade for online courses matched that for classroom-based courses. In this calculation of the average grade, course withdrawals were weighted as equivalent to a course failure, and the rate of withdrawal was much lower for students enrolled in classroom-based courses than for students enrolled in online courses.

If the statements above are true, which of the following must also be true of Cheever College?

正确答案: A

OG套题第31道

OG 套题31题,

Cheever
                    College
offers several online courses via remote computer connections, in addition to traditional classroom-based courses, a study of student performance at Cheever found that, overall, the average student grade for online courses matched that for classroom-based courses.  In this calculation of the average grade course withdrawals were weighted as equivalent to a course failure, and the rate of withdrawal was much lower for students enrolled in classroom-based courses than for students enrolled in online courses.

 

A Among students who did not withdraw, students enrolled in online courses got higher grades, on average, than students enrolled in classroom-based courses.

B The number of students enrolled per course at the start of the school term is much higher, on average, for the online course that for the classroom-base courses.

C There are no students who take both anonling and a classroom-based course in the same school term.

D Among Cheever College students with the best grades, a significant majority take online, rather that classroom-based, courses

E Courses offered online tend to deal with subject matter that is less challenging than that of classroom-based courses.

 

题干说online courses 学生的grade 和classroom-based courses的一样,但前者退出率高过后者,就可以推出前者没退出的学生的平均grade高过后者吗?(A项答案解释)

 

那怎么知道退出的是成绩好的还是坏的?还是我的中文翻译理解错了?   求大家帮看看

i think you could grasp the key ponts from "In this calculation of the average grade course withdrawals were weighted as equivalent to a course failure, and the rate of withdrawal was much lower for students enrolled in classroom-based courses than for students enrolled in online courses.". the lower the rate of withdraw, the higher average grade given grades of two types of courses are the same.

withdrawals were weighted as equivalent to a course failure,哦,那就是说退出等同于失败,就是说,凡是退出,就是O分了。这样就会拖累平均分了。原来是我理解成:退出还是有成绩的。

 

谢谢提醒!
