See the multi-choice question below:

Sentence 1: [I]t would be pornographic, if it weren't art (Walter Kendrick, the New York Times Book Review ). Others find that the novel's format--a combination of letters and rambling diatribes--makes the story repetitious and tedious.

Sentence 2: Walter thought the book was absolutely pornographic and should be burned.

If the first sentence is true, then is the second sentence true?
