Question

I need to know this analogy

Answer 1

Car is to key as fire is to match.

Answer 2

Match? Key starts a car, match starts a fire.

In order to answer word analogy questions, it is essential to see the relationship between the first two words.  To do  that, compose a sentence:  "A key is some that starts a car."  Now the proper word should be fairly clear for the second pair: A match is something that starts a fire.
