Reviewer: The book Art's Decline argues that European painters today lack skills that were common among European painters of preceding centuries. In this the book must be right, since its analysis of 100 paintings, 50 old and 50 contemporary, demonstrates convincingly that none of the contemporary paintings are executed as skillfully as the older paintings.
Which of the following points to the most serious logical flaw in the reviewer's argument?
(A) The paintings chosen by the book's author for analysis could be those that most support the book's thesis.
(B) There could be criteria other than the technical skill of the artist by which to evaluate a painting.
(C) The title of the book could cause readers to accept the book's thesis even before they read the analysis of the paintings that supports it.
(D) The particular methods currently used by European painters could require less artistic skill than do methods used by painters in other parts of the world.
(E) A reader who was not familiar with the language of art criticism might not be convinced by the book's analysis of the 100 paintings.

I had it between A and D
In retrospect I should have chosen A. It is just cleaner and I think the more familiar I am with a logical flaw the more it fits the bill

Premise 1. European painters lack skills that were common in the preceding century
Premise 2. In the book out of 100 paintings, 50 old, 50 new, none of the newer paintings are executed as skillfully as the older paintings.

Between 1 and 2 the flawed logic or assumption is that the book accurately

Here's where I get a little hung up.
In logical flaw questions, like strengthen and weaken we assume the answer prompts to be true, correct? I ask because I can see a wide array of answers to such logical flaw problems.

A also makes a lot more sense than B because although we can assume D to be true, the prompt tells us nothing about non-European artists. Then again the prompt doesn't tell us the book talks only about European artists, why could D not legitimately point out that these artists could possibly be non-European and hence the error ie because Euro artists are less skilled than world artists ->why we can't conclude that Euro artists between contemporary and old are not more or less skilled from the book;
