Hi

E-GMAT,

Please find my analysis below,

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 presentedA. 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.

B. The first provides evidence in support of the overall position that the historian defends; the

second is that position.

C. 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.

D. 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.

E. 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.

Now lets break this argument.

Historian: Newton developed mathematical concepts and techniques that are fundamental to

modern calculus....FACT1

. Leibniz developed closely analogous concepts and techniques.FACT2

It has traditionally been thought that these discoveries were independent. HISTORIAN OPINION....intermediate conclusion.

Researchers have,however, recently discovered notes of Leibniz’ that discuss one of Newton’s books on

mathematics. Researchers Opinion

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, SCHOLORS OPINIONS

it is virtually certain that the traditional view is false. Historians Opinions..... MAIN CONCLUSION.

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. Historion Opinion.

So as per the above understanding, First Bold face is the explanation to support the main conclusion.

and Second Bold Face as it mention However. I though i should be against the main conclusion.

With this understanding I'm able to eliminate all the choice but I'm not able to understand why in option D,second bold face statement support the main conclusion.

Thanks
