Everyone who has graduated from TopNotch High School has an intelligence quotient (IQ) of over 120. Most students with an IQ of over 120 and all students with an IQ of over 150 who apply to one or more Ivy League universities are accepted by at least one of them.

The statements above, if true, best support which of the following conclusions?

A.Every graduate of TopNotch High School with an IQ of 150 has been accepted by at least one Ivy-League university.

B.If a person is a high-school graduate and has an IQ of less than 100, he or she could not have been a student at TopNotch High School.

C.If a person has an IQ of 130 and is attending an Ivy-League university, it is possible for him or her to have graduated from TopNotch High School.

D.At least one graduate from TopNotch high school who has applied to at least one Ivy-League university has been accepted to one of them.

E.If a high-school graduate has an IQ of 150 and is not attending an Ivy-League university, then he or she did not apply to one of them.
看起来挺容易一归纳题，就突然想不通了。正确答案是C，也可以理解，比较纠结B选项。

"(B) The passage states that every graduate of TopNotch High has an IQ of over 120. The conclusion only states that the student is a high school graduate and that he has an IQ of less than 120. It does NOT state that he or she was a graduate of TopNotch High. It is possible, however, that after attending TopNotch High for a period of time, he or she graduated from another high school. If this is the case, the situation does not contradict the passage, but contradicts the conclusion (he or she was a student at TopNotch High). Hence, this conclusion is not valid. "

阴影部分是摘得曼哈顿对B 的解释。
还是不明白解释中所说的陈述范围是该如何理解。

请大家路过了，一起讨论下~谢了呢~

If a person is a high-school graduate and has an IQ of less than 100, he or she could not have been a student at TopNotch High School.

I believe:  

He or she may have studied at TopNotch but transferred to another school, from which he or she ultimately graduated.
