Hi, lets see how the argument structure is built
Lets Say Historian is the author of this argument , we refer historian as author from now on
Statement 1:
Newton developed mathematical concepts and techniques that are fundamental to modern calculus.
Leibniz developed closely analogous concepts and techniques.The above two statements are facts that the Author Quotes ( We can say this sets the context of the passage) Statement 2:
It has traditionally been thought that these discoveries were independent.In the Above statement author presents a generally held belief about Statement 1
Statement 3: Researchers have, however, recently discovered notes of Leibniz’s that discuss one of Newton’s books on mathematics.Author presents yet another fact: The fact is about researchers discovering some thing Statement 4:
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. Author says : Based on the findings some researchers have come to certain conclusion ( Researchers are of view that traditional belief is not true) Statement 5: A more cautious conclusion than this is called for, however.Author Says: Hey we need to be more careful to draw this conclusion ( Author's View)Statement 6: Leibniz’s 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.Author then gives reason why did he say so . In a way he is presenting a reasoning for his view So we know by now that the author's conclusion is the main conclusion and in re-word the conclusion of author as " It is too much to conclude that Leibniz’s work on calculus was based on Newton’s concepts and techniques on calculus."
So Authors view and researchers view are in opposite direction
Lets Analyze our Bold Face Statements which are in Statement 4:
1st Bold Face in Pink
What is the role played by the
pink part in statement 4 :It’s a fact presented by the researchers to conclude that the traditional belief is false
What is the Relation of this part to main conclusion . Since authors view is in opposite to view of researchers , certainly this statement is against the main conclusion.
2nd Bold Face which is in
green part
What is the role played by this statemnt : Oh this is the conclusion that researchers draw from a fact that they have presented
What is the Relation of this part to main conclusion: As noted above since this is researchers view ( conclusion ) it's against the author's view ( main conclusion of the argument)
So we can Say BF1 and BF2 are in the same direction, but are in opposite direction to the main conclusion of the argument.
best way to understand answer choices is to dissect them into parts and see if we get Yes/ No for each part.
Answer Choices
A \(The first is a claim that the historian rejects; the second is a position that that claim has been used to support\)
The first is a claim :
No. It’s a fact used by the researchers to support their conclusion.
that the historian rejects;:
No. The historian (author) does not reject this fact. He rejects the conclusion the researchers draw from this fact .
the second is a position :Yes. It is the conclusion made by the researchers so we can call this as position taken by the researchers .
that that claim has been used to support.:
No. Here ' that claim ' refers to BF1 ' . But since we know that BF1 is not a claim .
this choice is incorrect.
Option B:
The first is evidence that has been used to support a conclusion about which the historian expresses reservations; the second is that conclusionThe first is evidence :Yes. A fact can be called evidence when it is used to support some conclusion
that has been used to support a conclusion:Yes. It has been used to support the conclusion made by the researchers.
about which the historian expresses reservations;:Yes. the author opposes conclusion drawn by researchers from this fact(evidence)
the second is that conclusion:Yes. Here that conclusion refers to 'a conclusion' in the first part of answer choice which is is 'the conclusion' drawn by the researchers. ans this conclusion is opposed by author .
B is correct choice.
C:
The first provides evidence in support of a position that the historian defends; the second is that position. The first provides evidence :Yes. A fact can be called evidence when it is used to support some conclusion
in support of a position : Yes. It has been used to support the position( conclusion made by researchers) taken by the researchers
that the historian defends;:
No. The author does not agree with the researchers. He rather opposes it.
the second is that position. :Yes. here 'that position' refers to 'a position' mentioned in first part of answer choice . Since second BF2 is a potion ( conclusion of researchers) we can say that It is the position taken by the researchers and which the author
disagrees with.
Thus, this is not the correct choice.
D :
The first and the second each provide evidence in support of a position that the historian defends. The first and the second each provide evidence :
No. The BF1 is fact and hence can be called evidence. But BF2 is not a evidence (fact) . BF2 is a claim ( a conclusion) drawn by researchers based on BF1.
in support of a position that the historian defends. :
No. Here ' a position' refers to position taken by researchers. Since we know that author disagrees with conclusion drawn by researchers, so this is incorrect
E:
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 positionThe first has been used in support of a position : Yes. It’s a fact used by the researchers to support their conclusion or we can say that first is used to support position taken by the researchers.
that the historian rejects;: Yes author does not agree with conclusion drawn from this fact and hence opposes researchers position
the second is a conclusion: Yes Second is 'a conclusion' a conclusion drawn by researchers.
that the historian draws from that position.:
No. Second itself is "the position" taken by researchers . And researchers draw this position from a fact mentioned in BF1
this is not the correct choice.
