A history book written hundreds of years ago contains several inconsistencies. Some scholars argue that because the book contains inconsistencies, the author must have been getting information from more than one source.
The conclusion cited does not follow unless
(A) authors generally try to reconcile discrepancies between sources
(B) the inconsistencies would be apparent to the average reader of the history book at the present time
(C) the history bookâ€™s author used no source that contained inconsistencies repeated in the history book
(D) the author of the history book was aware of the kinds of inconsistencies that can arise when multiple sources are consulted
(E) the author of the history book was familiar with all of the available source material that was relevant to the history book

Anything that strengthens the possibility that our history book author did use multiple reference sources for his history book would strengthen the conclusion of the scholars.

E provides that.

If thats the case then there has to be little, if any, inconsistancies. This doest not support the conclusion.
(B) the inconsistencies would be apparent to the average reader of the history book at the present time. Cross this one

If there are inconsistencies it would be true for the present readers as well as the readers of the past. So cross this one too.
(C) the history bookâ€™s author used no source that contained inconsistencies repeated in the history book

This again does not support the conclusion. Cancle this(D) the author of the history book was aware of the kinds of inconsistencies that can arise when multiple sources are consulted.

If the author was aware that multiple sources can create inconsistencies then he would not have consulted multiple sources and hence this statement does not support the conlcusion.

(E) the author of the history book was familiar with all of the available source material that was relevant to the history book

I choose E because if the author of the history book was familiar with all the avalable source material that were relevant to the history book , only then could have given all the relavant informations,which resulted in inconsistancies because of many sources. So the correct choice.
Please give reasons for ur choices...

Javed.

This one is a real twister.

I think C is right after all. If the other sources (from which the author has allegedly copied) had the same inconsistencies as in our Author's history book then the information between our Author's book and the other books would have been CONSISTENT and would not have stood out.

Hi dwivedys,what about ur earlier explanation...whats wrong with that.

The logic that I used viz anything that could establish the author used multiple sources would strengthen the claim of the scholars still stands. However this falls short - we also need to figure out the REASON for the inconsistencies - None of the sources our history book author copies from would have those inconsistencies that make their way into our History Author's book.

One more thing - which may be an important consideration for this question - scholars are objecting to INCONSISTENCY and not DISCREPANCY (or error). An example of inconsistency could be as follows -
In one of the chapters in our History Author's book the following might appear - India gained independence in 1947.

In the same chapter elsewhere or in a different chapter the same
information could be represented as

India was still ruled by Britishers into 1947.

Now the information in the book becomes inconsistent.

Now imagine if ALL of the other sources had the SAME inconsistency - the charge that the Author copied the info from different sources would not have arisen. But because individually the potential sources that the author plucked the information from all reflect consistent information - it stands to reason that the author has copied from different sources and somewhere in that process the information has become inconsistent.

This is a very tough CR and I don't think I would have been able to answer it on the exam.

Wheew .. You guys freaked me out .. When I read the question I directly eliminated D and E, and then with more POE I was sure that answer is C. Then for the first 3 or 4 replies, you guys confirmed it was E ..

Thank god the OA is C

Anyways, this is an assumption question. The assumption connects the evidence and the conclusion. The conclusion is that in order for the book to contain inconsistencies, the author should've used multiple resources --> hence the ONLY source for inconsistencies is using multiple resources.

x --> Z
the assumptions are:
z --/-> x [ it's not the reverse cause and effect ]
y --/-> z [ it wasn't another cause that led to the effect ]

Therefore, the answer is clearly C.

The conclusion cited does not follow unless

(C) the history bookâ€™s author used no source that contained inconsistencies repeated in the history book
- If the author used only one source that contained, then those inconsistencies would have transferred over to the book as well. So, the argument made by some scholars would be negated.

Hi dwivedys,what about ur earlier explanation...whats wrong with that.

One reason as to why E is not the best choice:
If the author knew all the information and all the sources, then there would have been no inconsistencies. He would have chosen information from source(s) that he thought were true and included only that information in his book.
Some might argue that there is no way of infering that but to me, an author adding inconsistencies on purpose seems far fetched.

Remember, for CR questions you're allowed to use ONLY the information or statements presented in the question. Any answer choice that requires further background knowledge or external and unnccessary assumptions is wrong and considered out-of-scope.

Choice D requires the assumption that if the author is aware of inconsistencis in the sources he used he'll stop using them or find a solution for this problem by using alternative sources or using only one single source.

E doesn't affect the argument.

C on the other hand says that there are inherent inconsistencies to begin with

Good question though

For most of my CR logic I usually refer to Kaplan's approach.
