GWD7-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?

 

A.      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.

B.      The first is the position that the argument seeks to establish; the second presents an assumption on which the argument relies.

C.      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.

D.      The first is an objection raised against a position that the argument opposes; the second is the position that the argument seeks to establish.

E.       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.

 

Why is B?

The last sentence is the main conclusion!

The first---evidence to support the conclusion

The second---assumption that the conclusion relies on

Although the earliest surviving Greek inscriptions written in an alphabet date from the eighth century B.C.,这句是一个说明现象

 a strong case can be made that the Greeks actually adopted alphabetic writing at least two centuries earlier. 这句明显就是作者给出的观点啊

Now, the Greeks learned..., and in the process they would surely have adopted whatever convention the Phoenicians were then using with respect to the direction of writing.  你看结构，the Greeks do...是细节吧，用了and连接，则and后的内容也是细节，不会是主旨结论的。would surely have 就是一个假设的标志，不是肯定的结论只是推断的假设
