Questions 6-7
High-technology medicine is driving up the nation's health care costs. Recent advances in cataract surgery illustrate why this is occurring. Cataracts are a major cause of blindness, especially in elderly people. Ten years ago, cataract surgery was painful and not always effective. Thanks to the new technology used in cataract surgery, the operation now restores vision dramatically and is less expensive. These two factors have caused the number of cataract operations performed to increase greatly, which has, in turn, drive up the total amount spent on cataract surgery.
7. Each of the following, if true, would support a challenge to the author's explanation of the increase in the number of cataract operations EXCEPT:
(A) The overall population of the nation has increased from what it was ten years ago
(B) Any one individual's chance of developing cataracts is greater than it was ten years ago.
(C) The number of older people has increased during the last ten years.
(D) Today, health insurance covers cataract surgery for more people than it did ten years ago.
(E) People who have had unsuccessful cataract surgery are left with more seriously impaired vision than they had before the surgery.
觉得应该答案是D才对，因为D是支持原文说法的；而E可能导致做手术的数量减少，表明手术不安全。答案是E。

25. Certain governments subsidize certain basic agricultural products in order to guarantee an adequate domestic production of them. But subsidies encourage more intensive farming, which eventually leads to soil exhaustion and drastically reduced yields.
The situation above is most nearly similar to which one of the following situations with respect to the relationship between the declared intent of a government practice and a circumstance relevant to it?
(A) Certain governments subsidize theaters in order to attract foreign tourists. But tourists rarely choose a destination for the theatrical performances it has to offer.
(B) Certain governments restrict imports in order to keep domestic producers in business. But, since domestic producers do not have to face the full force of foreign competition, some domestic producers are able to earn inordinately high profits.
(C) Certain governments build strong armed forces in order to maintain the sort of discipline and morale that keeps armed forces strong, those forces must be used in actual combat periodically.
(D) Certain governments reduce taxes on business ventures are not always as successful as their owners hoped.
(E) Certain governments pass traffic laws in order to make travel safer. But the population-driven growth in volumes of traffic often has the effect of making travel less safe despite the passage of new traffic laws.
问题：原题目选C，可感觉国家建立武装力量的目的是discipline和morale，这个与经常打仗并不矛盾。E好像更像一些。

1. Should be E. ABCD each point out a reason that it might not be the technology improvement that caused the increase in number of surgery performed or the hiked bill. D says that because of the broader coverage of insurance, many poeple who otherwise would not be covered 10 years ago for their surgeries will be covered now. So it is the insurance policy that make the surgery affordable to more people, who receive the surgery. E is not relevant in countering the reasoning in the argument.

2. The logic follows that discipline and morale cannot be maintained after actual combat. I was thinking about this one but could not really link them together. If the answer is:
Build strong armed forces to maintan peace. To keep armed forces strong, the forces need to be used in actual combat.
The link is more obvious. Peace and combat are contradictary.

Can somebody explain 2T?
