陈向东逻辑-归纳-关于大学课程的

After graduating from high school, people rarely multiply fractions or discuss ancient Rome, but they are confronted daily with decisions relating to home economics. Yet whereas mathematics and history are required courses in high school curriculum, home economics is only an elective, and few students choose to take it.
Which of the following positions would be best supported by the considerations above?

A. If mathematics and history were not required courses, few students would choose to take them
B.Whereas home economics would be the most useful subject for people facing the decisions they must make in daily life, often mathematics and history can also help them face these decisions
C.If it is important to teach high school students subjects that relate to decisions that will confront them in their daily lives, then home economics should be made an important part of the high school curriculum
D.Mathematics, history, and other courses that are not directly relevant to a person's daily life should not be required part of the high school curriculum
E.Unless high schools put more emphasis on nonacademic subjects like home economics, people graduatingfrom high school will never feel comfortable about making the decisions that will confront them in their daily lives

THE ANSWER IS C AND I UNDERSTAND THAT.
BUT WHAT I DO NOT UNDERSTAND IS WHY A IS NOT THE CORRECT ANSWER. I'VE READ THE POST OF THE SAME QUESTION. BUT IT ONLY DISCUSSED WHY C IS A CORRECT ANSWER.

IN THE ARGUMENT, THE AUTHOR SAYS THAT FEW STUDENTS CHOOSE HOME ECONOMICS, WHICH IS AN ELECTIVE COURSE. STUDENTS ALL LEARN MATHEMATICS AND HISTORY BECAUSE THE TWO ARE REQUIRED COURSES.
WHY CAN'T I CONCLUDE THAT MATHEMATICS AND HISTORY WILL NOT BE CHOSEN IF THEY BECOME ELECTIVE COURSES?

题目中的信息都是assumption,而A只是题目中的一个 hiden assumption,不是可以从题中信息推导出的结论.
问题问得是以上信息支持哪个选项,所以应该是选择结论而不是hiden assumption..
不知道我理解的对不对..

这是一道归纳题哦，不是假设题。
“Which of the following positions would be best supported by the considerations above?”意思是下面哪个立场是被上文支持的，即由上文我们可以得到什么信息。

还是不理解为什么A不对啊~为什么你认为A是个hidden assumption呢？

Change the perspective: The question does not tell the attitudes of students towards math and history. Thus, it is possible that even if the two are optional, there will still be a lot students choosing them.
