在GWD-6-16的BF里有三个选项有The first provides evidence，有两个选项有The first is evidence，如果抛开其它因素，单纯就这两种表达来讲，有什么区别吗？是否会对解题有影响？

在GWD-7-18的BF题干里有一个表述， a strong case can be made that，这是表示事实，证据，还是结论。

希望能从这些表述本身给予解答，不要从答案倒推。比如说第一次见到这个表述，怎么理解，怎么根据这个理解去解题，像16题的两个表述，是完全一样，出题者完全是玩个小花样虚晃一枪，还是确实会对推测答案有一定的影响。

比较困惑

谢谢解答

没人应，偶把这两个题再贴一下吧，自娱一下。涂红色的是偶想问的。

偶还是不希望用倒推，从答案知道了这是个什么东东再去解释，而是刚看到这个题怎么认识，是什么解题思路。谢谢各位。

Historian:  Newton developed mathematical concepts and techniques that are fundamental to modern calculus.  Leibniz developed closely analogous concepts and techniques.  It has traditionally been thought that these discoveries were independent.  Researchers have,
                        however, recently discovered notes of Leibniz’ that discuss one of Newton’s books on mathematics.  Several scholars have argued that since the book includes a presentation of Newton’s calculus concepts and techniques, and since the notes were written before Leibniz’ own development of calculus concepts and techniques,
                    it is virtually certain that the traditional view is false.  A
                more cautious conclusion
                than this is called for,
                    however.  Leibniz’ notes are limited to early sections of Newton’s book, sections that precede the ones in which Newton’s calculus concepts and techniques are presented.

In the historian’s reasoning, the two boldfaced portions play which of the following roles?

1. The first provides evidence in support of the overall position that the historian defends; the second is evidence that has been used to support an opposing position.

2. The first provides evidence in support of the overall position that the historian defends; the second is that position.

3. The first provides evidence in support of an intermediate conclusion that is drawn to provide support for the overall position that the historian defends; the second provides evidence against that intermediate conclusion.

4. The first is evidence that has been used to support a conclusion that the historian criticizes; the second is evidence offered in support of the historian’s own position.

5. The first is evidence that has been used to support a conclusion that the historian criticizes; the second is further information that substantiates that evidence.

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.
