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's 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 portions in boldface play which of the following roles?
The first is a claim that the historian rejects; the second is a position that that claim has been used to support.
The first is evidence that has been used to support a conclusion about which the historian expresses reservations; the second is that conclusion.
The first provides evidence in support of a position that the historian defends; the second is that position.
The first and the second each provide evidence in support of a position that the historian defends.
The first has been used in support of a position that the historian rejects; the second is a conclusion that the historian draws from that position.
这个指保留意见
express reservations：持保留态度 原文里A more cautious conclusion than this is called for体现了这个态度
这种boldface题我都是直接看框架，since因为，两个因为，后面的逻辑肯定是所以，即结论，那么因为就是支撑结论的，所以BE看，而E的historian draw from错了，要注意审题。个人思路仅供参考
为什么D的第二句黑体会是evidence呢？难道不是claim吗？
A选项：historical并没有reject the claim,而是指出这样的事实，作为后面结论的支持；
B选项：express reservations：指的是A more cautious conclusion than this is called for。
C选项：作者反对结论，而不是defend（保卫，防卫）
E选项：第二句黑体字并不是historian的结论， 而是scholars的结论，因为是顺着Several scholars have argued that since...it is virtually certain...
express reservation 表达保留意见
express reservation 表示反对 不认识直接错.......
错选C。 C表示historian反对结对，而B中的 reservations 是保留意见
"A more cautious conclusion than this is called" 这个表示了保留意见
请问expresses reservations是什么意思啊？看起来像是支持？
E. The second boldface section presents not the historian’s conclusion but rather the
scholars’ conclusion, about which the historian expresses misgivings.
B E 纠结：
E. The second boldface section presents not the historian’s conclusion but
