Let us simplify the argument --
Monet is usually considered a founding member of French Impressionists ---> His descriptions are unlikely to do more than confirm what he thought to be trueThis is not a very strong argument. We see that the conclusion is drawn just based on the fact that Monet is considered a founding member of French impressionists. It is entirely possible that his descriptions might disagree with impressionism.
let us look at answer options --
Option A - IncorrectThe evidence given -- "founding member of French impressionists" -- is not questionable. We do not whether this is unverifiable also.
Option B - Incorrect"uses descriptions of a famous artist" is actually a part of the conclusion, not part of the supporting data/premise.
This part -- "the significance of Monet’s work is reflected in a recent discussion of art more than it was in his own descriptions" -- does not exactly support the main conclusion.
Option C - IncorrectThis does not support the
claim = conclusion by denying the opposite of the claim/conclusion. This should be clear from the reasoning mentioned above.
Option D - IncorrectThe two premises do not contradict each other.
Option E - Correct answerThe conclusion -- his descriptions are unlikely to do more than confirm what he thought to be true -- is based on the fact that Monet was a founding member of French impressionism.
