Which statement is an example of a complete analogy? a pen is like a mind reader. my cousin is like a whirlwind; she arrives out of nowhere, leaves a mess, and disappears. our road trip was like a long trip on a broken-down magic carpet. an atom is like the solar system.

An analogy is a comparison of two things that may be quite different from each other, but the statement explains that idea or thing by comparing to something familiar. Therefore, the only complete idea is the second option:

My cousin is like a whirlwind; she arrives out of nowhere, leaves a mess, and disappears.

Because the author is trying to say that his cousin does not behave well, he always makes a mess in the house and then instead of cleaning the disaster he made, he leaves.
