Hunter: Many people blame hunters alone for the decline in Greenrock National Forest's deer population over the past ten years. Yet clearly, black bears have also played an important role in this decline. In the past ten years, the forest's protected black bear population has risen sharply, and examination of black bears found dead in the forest during the deer hunting season showed that a number of them had recently fed on deer.

In the hunter's argument, the portion in boldface plays which of the following roles?

(A) It is the main conclusion of the argument.

(B) It is a finding that the argument seeks to explain.

(C) It is an explanation that the argument concludes is correct.

(D) It provides evidence in support of the main conclusion of the argument.

(E) It introduces a judgment that the argument opposes.

题干:猎人说,很多人指责猎人是G国家公园鹿群数量在过去十年下降的唯一因素。但是很明显,黑熊在这个问题上也贡献颇多。过去十年对森林公园中黑熊的保护导致黑熊数量急剧上升,而且在死去的黑熊肚子里也发现它们之中的很多在死前曾经捕食过鹿。

分析:BOLDFACE题目,抓住逻辑主客观定性和逻辑方向两点!首先很多人的指责明显是主观性的判断,其次,题干作为一个整体是在用实例来驳斥这个主观判断的。分析到这里答案就清楚了,选E。

例题:OG13-P508-28

Last year a record number of new manufacturing jobs were created. Will this year bring another record? Well, a new manufacturing job is created either within an existing company or by the start-up of a new company. Within existing firms, new jobs have been created this year at well below last year's record pace. Atthe same time, there is considerable evidence that the number of new companies,starting upwill be no higher this year than it was last year, and surely the new companies starting up this year will create no more jobs per company than did last year's start-ups. Clearly, it can be concluded that the number of new jobs created this year will fall short of last year's record.

In the argument given, the two portions in boldface play which of the following roles?

(A) The first is a prediction that, if accurate, would provide support for the main conclusion of the argument; the second is that main conclusion.

(B) The first is a prediction that, if accurate, would provide support for the main conclusion of the argument; the second is a conclusion drawn in order to support that main conclusion.

(C) The first is an objection that the argument rejects; the second is the main conclusion of the argument.

(D) The first is an objection that the argument rejects; the second presents a conclusion that could be drawn if that objection were allowed to stand.

(E) The first is a claim that has been advanced in support of a position that the argument opposes; the second is a claim advanced in support of the main conclusion of the argument.

题干:去年新增的制造业工作数量创造了历史记录,今年是否会创造新的记录呢?一个新的制造业工作的创造要么来自于一个现有的公司要么来自于新成立的公司。在现有的公司里,新工作的增长速度明显慢于去年。同时,大量证据表明新成立的公司数量不会比去年更多,而且基本可以确定今年平均每个新公司提供的职位也不会比去年的新公司更多。所以很明显,我们能得出结论,今年新工作增长的数量会较去年的记录下降

分析:我们首先对前后两部分BOLDFACE进行主客观定性,很显然,前后两部分均为主观性判断,具体表述我们在选项中进行考察。接下来我们可以很清晰地判断前后两段BOLDFACE的逻辑关系式正向而非逆向。同时符合这两点判断的选项只有A和B,再进一步考察B我们可以发现,在对第二段BOLDFACE的描述上B说第二段是一个支持主要结论的结论,而原文并没有B中所描述的FURTHER CONCLUSION。所以我们判断B错误,选A!
