The definition is at the beginning of the clue.
How the clue works
Look at Chose at the start, which is the definition, since ELECT as a verb means to pick. For the wordplay, "finishes" tells you to take the last letter of each word in "the final three classic test", and the five endings (E, L, E, C and T) line up to spell the answer.
