标题: GWD 7-18 这个也 想不通，NN们请给讲讲

Although the earliest surviving Greek inscriptions written in an alphabet date from the eighth century B.C., a strong case can be made that the Greeks actually adopted alphabetic writing at least two centuries earlier.  Significantly, the text of these earliest surviving Greek inscriptions sometimes runs from right to left and sometimes from left to right.  Now, the Greeks learned alphabetic writing from the Phoenicians, and in the process they would surely have adopted whatever convention the Phoenicians were then using with respect to the direction of writing.  Originally, Phoenician writing ran in either direction, but by the eighth century B.C. it had been consistently written from right to left for about two centuries.

 

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

 

1. The first is the position that the argument seeks to establish; the second reports a discovery that has been used to support a position that the argument opposes.
2. The first is the position that the argument seeks to establish; the second presents an assumption on which the argument relies.
3. The first presents evidence that is used in support of the position that the argument seeks to establish; the second presents an assumption on which the argument relies.
4. The first is an objection raised against a position that the argument opposes; the second is the position that the argument seeks to establish.

The first is an objection raised against a position that the argument opposes; the second is evidence that has been used to support that position.

答案选b 为什么不是a呢？

还有这个也不懂

Q27:

A significant number of complex repair jobs carried out by Ace Repairs have to be reworked under the company’s warranty.  The reworked jobs are invariably satisfactory.  When initial repairs are inadequate, therefore, it is not because the mechanics lack competence; rather, there is clearly a level of focused concentration that complex repairs require that is elicited more reliably by rework jobs than by first-time jobs.

 

The argument above assumes which of the following?

 

1. There is no systematic difference in membership between the group of mechanics who do first-time jobs and the group of those who do rework jobs.
2. There is no company that successfully competes with Ace Repairs for complex repair jobs.
3. Ace Repairs’ warranty is good on first-time jobs but does not cover rework jobs.
4. Ace Repairs does not in any way penalize mechanics who have worked on complex repair jobs that later had to be reworked.

There is no category of repair jobs in which Ace Repairs invariably carries out first-time jobs satisfactorily.

为什么选a?

Although
the earliest surviving Greek inscriptions written in an alphabet date
from the eighth century B.C., a strong case can be made that the Greeks actually adopted alphabetic writing at least two centuries earlier.  Significantly,
the text of these earliest surviving Greek inscriptions sometimes runs
from right to left and sometimes from left to right.  Now, the Greeks learned alphabetic writing from the Phoenicians, and in the process they would surely have adopted whatever convention the Phoenicians were then using with respect to the direction of writing.  Originally,
Phoenician writing ran in either direction, but by the eighth century
B.C. it had been consistently written from right to left for about two
centuries.

1. The
   first is the position that the argument seeks to establish; the second
   reports a discovery that has been used to support a position that the
   argument opposes.（这里没有应该反驳的论点，只有作者想支持的论点“希腊人采用字母写作至少有两个世纪那么早，从Significantly,开始都是作者的论据部分）
2. The first is the position that the argument seeks to establish; the second presents an assumption on which the argument relies.（would surely是假设语气的标致）

1. There
   is no systematic difference in membership between the group of
   mechanics who do first-time jobs and the group of those who do rework
   jobs.（这个选项相当于填补了一个GAP，排除systematic difference这个原因，使“公司重视水平”成为rework job 总是满意的唯一原因）
   
2. There is no company that successfully competes with Ace Repairs for complex repair jobs.(无关）
3. Ace Repairs’ warranty is good on first-time jobs but does not cover rework jobs.（无关）
4. Ace Repairs does not in any way penalize mechanics who have worked on complex repair jobs that later had to be reworked.（无关）
5. There is no category of repair jobs in which Ace Repairs invariably carries out first-time jobs satisfactorily.（无关）

assumption 的正确选项应不脱离与题干中元素的关系
