134. The more television children watch, the less competent they are in mathematical knowledge. More than a third of children in the United States watch television for more than five hours a day; in South Korea the figure is only 7 percent. But whereas less than 15 percent of children in the United States understand advanced measurement and geometric concepts, 40 percent of South Korean children are competent in these areas. Therefore, if United States children are to do well in mathematics, they must watch less television.

Which one of the following is an assumption upon in advanced measurement and geometric concepts than are South Korean children?

A.     Children in the United States are less interested in advanced measurement and geometric concepts than are South Korean children.

B.      South Korean children are more disciplined about doing schoolwork than are

C.     Children who want to do well in advanced measurement and geometry will watch less television.

D.     A child’s ability in advanced measurement and geometry increases if he or she watches less than one hour of television a day.

E.      The instruction in advanced measurement and geometric concepts available to children in the United States is not substantially worse than that available to South Korean children.

E是答案.

c为什么不对哈．．．．．

首先E对是肯定的。如果E不成立，即如果美国数学的教学理念比韩国要差很多，那可以说美国小孩数学差主要是因为美国学校教得不好，那么即使少看电视也不一定能提高他们的数学水平。所以E是一定要做的假设。

C是说，“想”学好数学的孩子会少看电视。这是不一定的，因为可能这孩子“想”做好数学，但他克制力不足，还是迷恋电视，所以他还是看很多电视，数学也学不好。“想”学好数学和“能”学好数学是不一样的。如果C改成，数学学的好的孩子都很少看电视我觉得倒是可以算一个必要假设。注意咬文嚼字哈，嘿嘿！

如果C是assumption 的话   那么前提和结论和结论就等于说的一句话   还用从前提+Therefore前面的现象来推出后面吗？  

It seems to test the concept that comparison must be made on the same ground, which, in this case, is the instruction.

C is a description in the passage, and hence has been considered already. Therefore, C cannot be used as an assumption.

我觉得C可以认为是个无关项,因为他用了一个who从句限定在想do well的样本中,实际上文中讨论的样本没有考虑样本的意愿,而且对C取反也不会对原文产生影响;
