Question

which of the following is an allusion? kelsey walks around like she knows everyone. my backyard is a garden of eden. taking that math test was a piece of cake.

Explanation:

An allusion is a reference to a well - known person, place, event, or literary work. "Garden of Eden" alludes to the biblical Garden of Eden. The first option is just a description of Kelsey's behavior, and the third option "a piece of cake" is an idiom (a figure of speech) but not an allusion as it doesn't refer to a specific well - known work, person, or event in the way an allusion does.

Answer:

B. My backyard is a Garden of Eden.
