Questions 1-2 are based on the following.
We have heard a good deal in recent years about the declining importance of the two major political parties. It is the mass media, we are told, that decide the outcome of elections, not the power of the parties. But it is worth noting that no independent or third-party candidate has won any important election in recent years, and in the last nationwide campaign, the two major parties raised and spent more money than ever before in support of their candidates and platforms. It seems clear that reports of the imminent demise of the two-party system are premature at best.
1. Which of the following is an assumption made in the argument above?
(A) The amount of money raised and spent by a political party is one valid criterion for judging the influence of the party.
(B) A significant increase in the number of third-party candidates would be evidence of a decline in the importance of the two major parties.
(C) The two-party system has contributed significantly to the stability of the American political structure.
(D) The mass media tend to favor an independent or third-party candidate over a candidate from one of the two major parties.
(E) The mass media are relatively unimportant in deciding the outcome of most elections.
我觉得D也有道理呀.即使mass media有足够的力量，也要它喜欢独立人士或第三党派人士才会有这类人被选上

9. Determining the authenticity of purported pre-Columbian artifacts is never easy. Carbon-14 dating of these artifacts is often impossible due to contamination by radioactive palladium (which occurs naturally in the soils of Central and South America). However, historians and anthropologists have evolved two reliable criteria, which, utilized in combination, have proven effective for dating these artifacts. First, because authentic pre-Columbian artifacts characteristically occur in a coarse, granular matrix that is shifted by major earthquakes, they often exhibit the unique scratch patterns known as gridding. In addition, true pre-Columbian artifacts show a darkening in surface color that is caused by centuries of exposure to the minute amounts of magnesium in the soil of the Americas.
The criteria above would be LEAST useful in judging the authenticity of which of the following?
(A) An ax head of black obsidian, unearthed from a kitchen midden
(B) A pottery bowl with a red ocher design, found in the ruins of a temple
(C) A set of gold ear weights, ornamented with jasper pendants
(D) A black feather cape from a king’s burial vault
(E) A multicolored woven sash found near the gravesite of a slave
这道题该怎么理解，我选的Ｃ．

我觉得D是一个有关答案，可是他是驳斥原文的，所以错。

1. D is out of scope. Whether media favor third party or not would not affect the reasoning in the question: raise lots of money --> the two parties are still important. A basically support the reasoning. In CR, you have to find the original argument and fill in the gap within the argument itself. You picked D because you thought the argument is about who would win the election. But that is not the argument.

2. D. You should know that "feather" cannot stand any scratching. And I would think that nothing is really "buried" if it is in a vault.

I understand the first question this way.

1) choice D (media prefer other canidate) + (no canidate of other party is chosen) -> media is not important.

2) but the conclusion is "the reports of the imminent demise of two party system are premature", which asks about the party influence, not the media influmence.

So Choice D is not correct.

What do you think?

我想请教一下关于逻辑大全-C-1题。我认为本文最后提到“取消两党制为时过早”，那么为什么选c会错，c中提到两党制对稳定美国社会有好处。谢谢

回楼上：
作者认为两党制暂不能取消，但没有表达两党制与稳定性的关系。
他用two major parties raised and spent more money than ever before in support of their candidates and platforms来支持他的论点，一定是他认为这一现象有说服力，也就是说，钱越多，影响力就越大。所以选A

可不可以理解为C是结论而A是假设呢？

C-9 能不能理解为黑色的看不出a darkening in surface color
