请教LSAT15-IV-8\9

8.The years 1917,1937,1956,1968,1979and 1990 are all notable for the occurrence of both popular uprisings and near-mamimum sunspot activity.During heavy sunspot activity,there is a sharp rise in positively charged ions in the air people breathe,and positively charged ions are known to make people anxious and irritalbe. Therefore, it is likely that sunspot activity has actually been a facotr in triggering popular uprising.
问逻辑相似?
C. Usually cold weather last Dec. coincided with a rise in fuel prices When it is cold, people use more fuel to keep warm, and when more fuel is used, prices rise.Therefore, if prices are high next winter, it will be the result of cold weather.
E.Acme's most productive managers are consistently those who occupy the corner offices,which have more windows than other offices at Acme. Since people are mor alert when they are exposed to abundant natural light,the greater productivity of these managers is probably at least in part a result of their working in the corner offices.
我觉得C\E皆可,请问C错在哪? Ans:E
另外,请问E-LSAT是否无法复制\粘贴,我打字好辛苦

9.Since anyone who supposes the new tax plan has no chance of being elected, and anyone who truly understands economics would not support the tax plan,only someone who truly understands economics would have any chances of being elected.

The reasoning in the argument is flawed because the argument ignores the possiblity that some people who
A.truly understand economics do not support the tax plan
B.truly understand economics have no chance of being elected.
C.do no support the tax plan have no chance of being elected.
D.do no support the tax plan do not truly understand economics
E.have no chance of being elected do not truyly understand economics
Ans.B
我一见some, all的题就晕头了,有什么办法吗?
这种题我怎么也做不出来.

谢谢!

有点疑问

B,E和原文的论证过程我也是这么做,所以才认为B,E皆可.这两个论证过程完全一致啊.
做这种逻辑相似题,只要能看出这样论证结构就可,是吗?难然还要考虑谁是谁的充分\必要条件吗?只要能看出谁推出谁就行了吗?

8.一个现象:popular uprisings 和near-mamimum sunspot activity同时发生
heavy sunspot activity --> positively charged ions -> people anxious and irritalbe
结论: heavy sunspot activity --> people anxious and irritalbe
原文说的是: 前者是 a facotr in 后者, 前者是后者的一个必要条件
E) most productive managers 和occupy the corner offices COINCIDE
corner offices有充足的光线 -> people are mor alert when they are exposed to abundant natural light -> most productive managers
结论: working in the corner offices -> greater productivity
前者at least in part a result of 后者: 前者是后者的一个必要条件
C) cold weather last Dec. coincided with a rise in fuel prices
it is cold -> people use more fuel -> prices rise
结论: cold weather -> high prices
it will be the result of : 前者是后者的充分条件
