18.   （假设）In the past decade, a decreasing percentage of money spent on treating disease X went to pay for standard methods of treatment, which are known to be effective though they are expensive and painful. An increasing percentage is being spent on nonstandard treatments, which cause little discomfort. Unfortunately, the nonstandard treatments have proved to be ineffective. Obviously, less money is being spent on effective treatments of disease X than was spent ten years ago.

Which one of the following, if assumed, allows the conclusion above to be properly drawn?

(A) Varieties of disease X requiring expensive special treatment have become less common during the past decade.

(B) Nonstandard methods of treating disease X are more expensive now than they were a decade ago.

(C) Of total medical expenditures, the percentage that is due to treatment of disease X increased during the past decade.

(D) Most of the money spent on treating disease X during the last decade went to pay for nonstandard treatments.（E）

(E) The total amount of money spent on treating disease X slowly declined during the past decade.

我看了原来的帖子还是不太明白,即使没有假设(E)还是可以得到DECREASING PERCENTAGE, LESS MONEY第四个答案又错在那里呢?

21        （支持）Medieval Arabs had manuscripts of many ancient Greek texts, which were translated into Arabic when there was a demand for them. Medieval Arab philosophers were very interested in Aristotle’s Poetics, an interest that evidently was not shared by Medieval Arab poets, because a poet interested in the Poetics would certainly have wanted to read Homer, to whose epics Aristotle frequently refers. But Homer was not translated into Arabic until modern times.（看清楚题中的一些内容）

Which one of the following, if true, most strongly supports the argument above?

(A) A number of medieval Arab translators possessed manuscripts of the Homeric epics in their original Greek.

(B) Medieval Arabic story cycles, such as the Arabian Nights, are in some ways similar to parts of the Homeric epics.

(C) In addition to translating from Greek, medieval Arab translators produced Arabic editions of many works originally written in Indian languages and in Persian.

(D) Aristotle’s Poetics has frequently been cited and commented on by modern Arab poets.（A）

(E) Aristotle’s Poetics is largely concerned with drama, and dramatic works werewritten and performed by medieval Arabs.

我看了原来的帖子,我的理解是HOMER是书,但是人们已经读到EPICS就不用再读HOMER所以也没有再翻译的必要.请朋友们指教.

1、这道题我想你是不是对题干的意思没有理解？我尝试翻译一下：

用于“标准治疗”的钱的比例下降了，“非标”的比例上升了。结论：用于标准治疗的钱少了。

一看这个，首先找的就是10年来总的花费没有变的选项。结果E说总的钱下降了。比例下降，总数下降，当然钱少了，成立。

而D说大部分的钱花在了“非标治疗”上，这是一个明显混淆的选项；因为多少算大部分？他们的比例各是多少题目并没有明确说，也许非标一直都是占大部分呢。这是ETS的陷阱，不幸，你掉进去了。

2、“我看了原来的帖子,我的理解是HOMER是书,但是人们已经读到EPICS就不用再读HOMER所以也没有再翻译的必要.请朋友们指教.”

    这个理解是不对的，文中说了，如果对EPICS感兴趣，一定就会去看homer，肯定就会翻译。A说当时Homer手稿他们有，恰好说明是他们不感兴趣的原因而没有翻译，原文推理就严谨了。属于架桥型假设。

Sufficient assumption

P1: A decreasing percentage of money spent on treating disease X went to pay for standard methods of treatment, which are known to be effective though they are expansive and painful.

P2: An increasing percentage is being spend on nonstandard treatment, cause little discomfort , but ineffective.

C: Less money is being spent on effective treatments of disease X than was spent 10 years go.

Well, percentage does not equal to the whole amount. In this case, if the " decrease percentage of money paid " means less money paid, then it must be true that the total amount of the money goes for X can't be increased. It could only go down.

Perfectly matches our answer - D.
