求解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.

没理解这题什么意思啊，求各位帮忙

我来翻译一下：

虽然发现幸存最早以字母表达的希腊文字创作于公元前八世纪，有很可靠的证据表明希腊人至少两个世纪前就已经学会了字母。很明显可以看出，这些幸存的文字有时从左往右写，有时从右往左写。希腊人是从腓尼基人那里学会的字母，在学习过程中自然而然也照搬了腓尼基人在书写方向上的习惯。早先腓尼基人的文字确实是两个方向的，但是到公元前八世纪为止他们已经有两个世纪只从右往左写了。

这段话说明了希腊人是在腓尼基人改为只从右往左写之前从他们那里学习的字母，即比公元前八世纪还要早至少两个世纪。回看文章就可以看出，第一个括号里是作者努力证明的观点；后面是推导这个观点的过程，第二个括号里是作者的假设，没有这个假设整个推导串不起来。
