Student: Before completing my research paper I want to find the book from which I copied a passage to quote in the paper.

Which one of the following most logically completes the student's argument?
(A) I will have to include an inaccurate citation
(B) I will be unable to complete my research paper
(C) If I do not find the book, my research paper will suffer
(D) If I do not find the book, I will include the quotations without an accurate citation
(E) If I do not find the book, I will be unable to complete my research paper
As always, the devil lies in the detail! The conclusion is "completed paper will be much better with quotation than without one". Now we need to find supporting evidence for the same.
Premise says, the student wanted to find the book that he copied a passage to cite a quotation. Below are the conditions that come with it.
No book -> No accurate citation (like the book name is lost, Page #, evidence cannot be provided that easily)
No accurate citation -> No quotation (or simply, the student cannot copy it word by word, exactly as it is)
A - says that the student will have to include inaccurate citation. No this doesn't support in any way for quotation.
B - says that quotation is necessary condition. but it is only a sufficient condition. GMAT tests this often.
C - denotes that if the book is not found, the quality of research paper will suffer. Yes, this works. Option C supports the conclusion that without the book, the research paper will suffer. Hold to it.
D - Nowhere in the argument that it is mentioned that the student will include quotations without accurate citation. Besides, we need support for the conclusion regarding the research paper's quality (better or worse). Eliminate D
E - Again necessary vs sufficient condition. We can infer that citation and quotation are sufficient conditions, not necessary conditions.
C best supports conclusion, and is the answer
