Hi
AndrewN hope you’re well!
I have two precise queries around conclusion/inference based cr questions:
1. How to know wether the question wants us to point out a conclusion already present in the stimulus or we have to recognise one from the answer choices that is engendered out if the information given? Is there a specific question type for each?
2. How different is main point from the conclusion? Would you say that the main point and conclusion for the question above is the same?
Thanks in advance. I appreciate your help, always!
Posted from my mobile deviceHello,
Shikhar22. Good questions. I will attach an image below to assist with my answers.

Notice that the question stem asks explicitly about
the conclusion drawn in the argument. We know we are dealing with a standard
LSAT identify-the-argument question, then, rather than an inference question, in which we might be given background information and premises but no discernible conclusion. I say "LSAT" question because apart from
boldface questions or the occasional
complete the passage, there really is no analogue on the GMAT™ for this type of question. You may have to evaluate an argument, but you are not asked to do so here. This is more like labeling something. Even the more old-fashioned "method of reasoning" or "logical flaw" question types do not follow this format.
That said, the
main point and
conclusion are often one and the same. How do we identify the conclusion? A basic litmus test is to place "thus" or "therefore" ahead of the line in question. If the word fits
as a result of the line or lines surrounding it, the information they convey, then you have likely found a conclusion. By contrast, a
premise will often follow a "because" framework:
Because X [premise], [then] Y [conclusion]. How about we break down this passage to see how these tests can be brought to bear?
- Sentence one provides background information only. You might think the first part serves as a premise for the latter, the part that follows the comma, but a careful look at the frame of the so-called conclusion would reveal otherwise. Consider:
[Because] Novel X and Novel Y are both semiautobiographical novels... [therefore] which might lead one to suspect plagiarism...
There is a judgment or commentary in which might that is different from saying because of this, such-and-such is the outcome. That is, instead of a premise-conclusion relationship, we are being told about a possible conclusion one can reach, not unlike the difference between the famous line, "I think, therefore I am" and my telling you that René Descartes posited that he thought, therefore he was. The quotation fits the premise-conclusion relationship, while the latter is a statement. All of this is to say that the opening line of the passage is a statement of fact, neither a premise nor a conclusion. - Sentence two begins with the conclusion and finishes with its supporting premise. Just who, exactly, thinks that something is more likely? That is an opinion or argument, not a fact. Notice that we can transpose the two parts of the sentence to perfectly fit the premise-conclusion mold:
[Because] both authors are from very similar backgrounds and have led similar lives, [therefore] it is more likely that the similarity... in the two novels is coincidental.
The since of the original sentence is used not in the temporal sense, but synonymously with because.
With that out of the way, we can examine the answers one by one.
(A) fails because it restates the background information.
(B) fails because it also more or less restates the background information.
(C) fails because it mislabels the
premise of the final line as the conclusion.
(D) restates the view that logically follows the premise and background information, so it is difficult to argue against.
(E) fails because the
if conditional is
not a part of the passage at all. The passage provides statements of fact instead, except as I have noted above. To illustrate the difference, take the following simple notions:
1)
Since it is raining, I will go to the movies.2)
If it is raining, I will go to the movies.The first presents a causal relationship; the second introduces a separate consideration—it may not be raining (and I may not go to the movies). In the passage, we see the first type of sentence instead of the second. It really is that simple.
I hope all of the above proves helpful. Thank you for thinking to ask.
