问题 Students who are interested in______are most UNLIKELY to take this course?
If a student never skips a class and gets an overall mark of 80 (out of 100) for assignments, what is the minimum mark that the student must obtain in the final exam in order to get 85 (out of 100) as the final mark of the course?

选项 A、80.
B、85.
C、90
D、95

答案C

解析 推论题。第五段介绍了课程最终的考核方式最终分数(final mark)=考勤分(participation)×10%+作业分(assignments)×60%+期末考试分(final test)×30%。照此公式,再结合题目要求(全勤分100分,作业分80分),可以得出要得到85分的最终成绩,应该在期末考试中拿到(85-100 × 10%-85 × 60%)÷30%=90分,故选C。
