Explanation
Correct answer: B.
Choice B is the best answer because it most logically follows from the text’s point about zines today. The text describes zines as a form of expression that goes back to the 1920s and asserts that "this old form persists." The text then indicates that multiple zines exist in the US today and that they are popular enough to support annual festivals, a point that suggests that people continue to view zines as a meaningful form of expression.
Why the other choices are wrong
Choice A
Choice A is incorrect because the text’s point about current interest in zines in the US doesn’t logically suggest that zine creators can reach a larger audience by posting online. The text indicates that zines have long had an audience, and there’s no indication that online posts have caused that audience to grow; there’s no mention of zine creators’ use of the internet at all.
Choice C
Choice C is incorrect because the idea that zine creators can explore new art forms—while objectively true—isn’t logically connected to the text’s discussion of zines as an existing form of expression (one that often includes art) or the point that zines are still popular enough in the US to support annual festivals.
Choice D
Choice D is incorrect because the point that zines are popular enough in the US today to support annual festivals doesn’t logically suggest that zines present mainstream culture (or are themselves mainstream); moreover, the text states that zine creators often "challenge mainstream culture."
