PS:Blue dotted lines are just for reference purpose and clarity

A is not possible to come up with since not much info is available.
C also is something similar in reasoning since not much info about how much work Devon has done is available.
E loses out when it say's non of the Devon's CA works are highly original. Also we are not sure how 'few' stands up.

I'm stuck with B and D. Chose B since Devon might have abstract work that fulfills originality criteria(consider the top-right part of the graph).
D, on the other hand, says most abstract works are not OP. So, am i right to say that few abstract works are original, indirectly saying most of them are not OP since OP's are mostly original.?

I marked B actually.

Hi lnm87

From the statement, we know about two things:
(1) All (or most) of her oil --> highly original
(2) Most of her abstract --> not highly (or much) original

(B) can also be written as "Most of her late works were not abstract ones". Unfortunately, nothing in the statement mentions about MOST (or few) of her late work.

(D) Most, if not all, of Devonshire's abstract works are NOT oil paintings.. This is basically the conclusion of (2)+ contrapositive of (1) as follows:
(2) + ~(1) Most of her abstract --> not highly original --> not her oil

Your diagram method is correct to some extent, but it may only be effective for limited conditional chain. As more information (e.g. "abstract works") are fed, the diagram eventually becomes more complex and difficult to fit the new information into it. We will waste time and labor unnecessarily.

For layered-inference type questions, it is better to first establish conditional diagrams. Later, establish any conditional chains whenever possible before looking at answer choice, just as I did for (D)

We only know that few abstract are much original. Rest (or most) can have no originality or high originality. In case they are highly original, they can be oil painting also.

There is no correct answer for this question.

Experts please help.

E) Few or none of Devonshire's critically acclaimed works are highly original.


Oil paintings --- few are popular among collectors ----- all highly original ---- created late in his career
Abstract work ---- very few are highly original

Let’s go only based on given info. No assumptions.

A) Most of Devonshire's works that are not popular with collectors are highly original. ------------------- only oil paintings are not popular, we do not know about abstract work’s popularity. NOT INFERABLE.

B) Few of the works produced late in Devonshire's career are abstract works. ---------- the argument actually says opposite that all highly original work (oil paintings) were produces late in his career. Not abstract work. NOT INFERABLE.


C) Most, if not all, of the works produced late in Devonshire's career are oil paintings. -------------- yeah okay, but he also produced some abstract work (few of his abstract work demonstrated much originality) late in his career. NOT 100% INFERABLE.

D) Most, if not all, of Devonshire's abstract works are not oil paintings. ------------------- Now this makes more sense since we know that abstract work did not have much originality, and oil paintings were all original. INFERABLE. CORRECT

E) Few or none of Devonshire's critically acclaimed works are highly original. -------------- reverse relationship. NOT INFERABLE. ELIMINATE
