Q18:

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.
   
   
5. 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： B

我不太明白文章画红线的部分的作用。说支持后面吧，跟后面的推理有不一样。因为后面说是GREEK是从右往做写，但是这部分说的是从左到右，或者从右到左。

希望有人解答一下
