Critic: All of Devonshire's oil paintings are highly original, though few of them are critically acclaimed or popular with collectors. Remarkably, Devonshire produced no highly original works until late in his career, and few of his abstract works demonstrate much originality.
If all of the critic's statements are true, which one of the following must be true?
A) Most of Devonshire's works that are not popular with collectors are highly original.
B) Few of the works produced late in Devonshire's career are abstract works.
C) Most, if not all, of the works produced late in Devonshire's career are oil paintings.
D) Most, if not all, of Devonshire's abstract works are not oil paintings.
E) Few or none of Devonshire's critically acclaimed works are highly original.

This is how i have tried to solve this question. Refer snapshot.

Originaliity Oil Paintings.png [ 96.08 KiB | Viewed 3619 times ]
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)
