The correct answer is the second option: convey a lot of information quickly. An allusion is a reference that the author and the readers both know. For example, George Washington can be an allusion, as well as World War II. There is no need to explain who or what the allusion is, but its presence indicates info to the reader as a comparison to a character or event already in the text. Hoped I was able to help! Mark me brainly if you can:)
