今天小编为大家选取了OG官方指南中比较有代表性，必要有难度的几道题目，帮助大家练练手。
1. (OG66)To protect certain fledgling industries, the government of Country Z banned imports of the types of products those industries were starting to make. As a direct result, the cost of those products to the buyers, several export-dependent industries in Z, went up, sharply limiting the ability of those industries to compete effectively in their export markets.
Which of the following conclusions about Country Z's adversely affected export-dependent industries is best supported by the passage?
MUST BE TURE QUESTION
(A) Profit margins in those industries were not high enough to absorb the rise in costs mentioned above.
(B) Those industries had to contend with the fact that other countries banned imports from Country Z.
(C) Those industries succeeded in expanding the domestic market for their products.
(D) Steps to offset rising materials costs by decreasing labor costs were taken in those industries.
(E) Those industries started to move into export markets that they had previously judged unprofitable.
正确答案A
2.(OG62)When hypnotized subjects are told that they are deaf and are then asked whether they can hear the hypnotist, they reply, "No." Some theorists try to explain this result by arguing that the selves of hypnotized subjects are dissociated into separate parts, and that the part that is deaf is dissociated from the part that replies.
Which of the following challenges indicates the most serious weakness in the attempted explanation described above?
WEAKEN QUESTION
(A) Why does the part that replies not answer, "Yes"?
(B) Why are the observed facts in need of any special explanation?
(C) Why do the subjects appear to accept the hypnotist's suggestion that they are deaf?
(D) Why do hypnotized subjects all respond the same way in the situation described?
(E) Why are the separate parts of the self the same for all subjects?
错选E应选A
OG解释：Which question points to a weakness in the theory?
According to the theory, hypnotized people dissociate themselves into separate parts: the hearing part and the deaf part.
Then, they must be using the hearing part of themselves when they respond to the hypnotist's question; obviously, if they were using the deaf part of themselves at that point, they would not hear or thus respond at all.
So, if they are using the hearing part of themselves, as the theorists maintain, why would they respond "No" to the question, "Can you hear me?" The hearing part would more logically answer "Yes."
D The theorists' explanation, if true, can help answer this question, so this challenge does not
解释一：这些实验对象在催眠过程中被告知是无法听到声音的， 但当有人问话的时候他们按照被告知的逻辑做出了反应。即：他们认为自己是聋子，无法听到声音。
事实是他们仍旧能够听到声音。最大的矛盾就是，既然听不到声音为什么还会做出反应。注意题目是要求MOST serious weakness
注意看结论，寻求与结论相反的答案。
结论认为这个现象是失聪与reply相剥离的结果，那么推翻这个结论就是两者没有剥离。即，听到便说听到，Then该回答yes。
解释二：Theorists的解释说the selves of hypnotized subjects are dissociated into separate parts，那么被催眠的人的所有器官都成为孤立的，没有任何内在的联系。聋的部份(耳朵)，回答的部份(嘴)，如果是是各自独立的话，嘴的回答就应该是随机的，则应有时回答“Yes”。而实验证明嘴每次都回答的是“No.” ，这说明在the part that is deaf 和the part that replies间必然有一种内在的联系。(A)对theorists的解释提出了很好的质疑，从而起到削弱的作用
3. OG74. Which of the following most logically completes the argument below?
Using broad-spectrum weed killers on weeds that are competing with crops for sunlight, water, and nutrients presents a difficulty: how to keep the crop from being killed along with the weeds. For at least some food crops, specially treated seed that produces plants resistant to weed killers is under development. This resistance wears off as the plants mature. Therefore, the special seed treatment will be especially useful for plants that
填空题，ASSUMPTION QUESTIONS
(A) produce their crop over an extended period of time, as summer squash does
(B) produce large seeds that are easy to treat individually, as corn and beans do
(C) provide, as they approach maturity, shade dense enough to keep weeds from growing
(D) are typically grown in large tracts devoted to a single crop
(E) are cultivated specifically for the seed they produce rather than for their leaves or roots
C The resistance wears off as the plants mature没看懂!!
4. In countries where automobile insurance includes compensation for whiplash injuries sustained in automobile accidents, reports of having suffered such injuries are twice as frequent as they are in countries where whiplash is not covered. Presently, no objective test for whiplash exists, so it is true that spurious reports of whiplash injuries cannot be readily identified. Nevertheless, these facts do not warrant the conclusion drawn by some commentators that in the countries with the higher rates of reported whiplash injuries, half of the reported cases are spurious. Clearly, in countries where automobile insurance does not include compensation for whiplash, people often have little incentive to report whiplash injuries that they actually have suffered.
In the argument given, the two boldfaced portions play which of the following roles?
黑体字题
(A) The first is a claim that the argument disputes; the second is a conclusion that has been based on that claim.
(B) The first is a claim that has been used to support a conclusion that the argument accepts; the second is that conclusion.
(C) The first is evidence that has been used to support a conclusion for which the argument provides further evidence; the second is the main conclusion of the argument.
(D) The first is a finding whose implications are at issue in the argument; the second is a claim presented in order to argue against deriving certain implications from that finding.
(E) The first is a finding whose accuracy is evaluated in the argument; the second is evidence presented to establish that the finding is accurate.
文章讨论的是一些评论家说这些报告一般是假的这样的结论是不对的!而不是说第一个黑体部分是不是正确，作者给出的信息都是正确的。换句话说确实是有两倍的报告，而这些报告是否真实才是要讨论的，所以finding是对的，finding的含义是受质疑的。
D，错选E，warrant这个单词不认识
5. In the United States, of the people who moved from one state to another when they retired, the percentage who retired to Florida has decreased by three percentage points over the past ten years. Since many local businesses in Florida cater to retirees, these declines are likely to have a noticeably negative economic effect on these businesses and therefore on the economy of Florida.
Which of the following, if true, most seriously weakens the argument given?
(A) People who moved from one state to another when they retired moved a greater distance, on average, last year than such people did ten years ago.
(B) People were more likely to retire to North Carolina from another state last year than people were ten years ago.
(C) The number of people who moved from one state to another when they retired has increased significantly over the past ten years.
(D) The number of people who left Florida when they retired to live in another state was greater last year than it was ten years ago.
(E) Florida attracts more people who move from one state to another when they retire than does any other state.
C错选E
本题是典型的数值、比例题
文章说了是退休后去弗罗里达的人的百分比变少了，而退休后去弗罗里达的人的百分比并不能说明人数的变化，要反驳很简单，就是虽然百分比变少了，但是退休后去其他地方的人总数变多，所以退休后去弗罗里达的人数还是有可能变多，所以选C，而E只是比较相对数值，不是绝对数值，显然不对。
