My answer key for this question actually shows the correct answer as
(C) - are you sure that you're looking at the correct section?
In case you meant to type
(C), here's the breakdown!
This question is asking us to complete the argument - in other words, we have to find a conclusion that follows from the information already listed. Inference time! With so much conditional logic in play, let's get diagramming:
(conditional): If no book --> no accurate citation
(conditional): if no accurate citation --> no include quote
(conditional): if no include quote --> paper won't be as good as it could be!
We can string those together! Three answer choices start with "if I don't find the book", but only one ends with something we can link to!
(C) concludes that without the book, the paper will suffer - i.e., it won't be as good as it could be!
Let's take a look at each of the incorrect answers:
(A) Why would we have to include an inaccurate citation? We still might find the book, and without the book, the conditionals indicate we'd just remove the quote!
(B) Nothing indicates that the paper can't be completed! We might not be able to include the quote without the book, but we could still finish the paper!
(D) Without the book, the conditionals above tell us that we won't use the quote, NOT that we'll use it without the right citation!
(E) Again, without the book, we can just remove the quote, and still presumably finish the paper.
Does this help clear a few things up?
