19. In a recent advertisement, a major cereal company contended that the better educated people are the more likely it is that as children they regularly ate oatmeal. As evidence, the company cited a national random survey of college graduates in which four-fifths of all those surveyed reported having eaten oatmeal at least once a week when they were young.
Which one of the following is an additional piece of information that would support the cereal company's conclusion?
(A) Four-fifths of all current college graduates eat oatmeal regularly.
(B) Fewer than four-fifths of those without a college degree ate oatmeal regularly when they were children.
(C) Among people who have additional education beyond college, four-fifths ate oatmeal regularly when they were children.
(D) More than four-fifths of the population at large-college graduates and nongraduates combined-ate oatmeal regularly when they were children.
(E) Those college graduates who did not eat oatmeal regularly when they were children did eat oatmeal on an occasional basis.
why the correct answer is B, not C
为什么会选C呢？
前面讲那么多高学历的人很多都是吃麦片粥的，那如果不是高学历的人吃麦片粥的比例也和他们一样多，那麦片粥不就不起作用吗？
只能说不是高学历的人吃麦片粥的比较少，这样才能显示它的作用。
C, if anything, weaken the argument, since if the argument estabshes, then the ratio of those beyond college should be higher than 4/5, not just 4/5, right?
thank you. you are 100 percent right. that is why the ratio of those guys without college degree is less than 4/5
退一步海阔天空哦。
把B取非就会weaken结论了。
