Question

Why do we group artworks with similar characteristics into periods or styles?

Answer 1

The correct answer is B. Periods or styles are merely categories serving as a basis for us to study the vast world of art with a clearer order than it would be without such categories. A. and C are wrong, for each artwork has a value of its own, and critics themselves still argue over which pieces should be added in textbooks or not; these categories weren't created to denigrate any artwork.
