Question

which best describes the overall purpose of \youth activism and animal rights\? to entertain readers with a sad story to educate readers about an important issue to convince readers to join a cause to inform readers about a historical figure

Explanation:

A work titled "Youth Activism and Animal Rights" centers on a social issue (animal rights) and youth engagement with it. Its core goal is to persuade readers to support and join the animal rights cause through highlighting youth activism. The other options do not fit: it is not focused on entertainment via a sad story, basic education alone (it goes beyond informing to persuading), or a historical figure.

Answer:

to convince readers to join a cause
