Two analogies that relate actions with their consequences are given in the form "A : B. C : ?". The phrase "A : B" relates action A to consequence B. Your task is to replace the question mark (?) with the appropriate consquence of the given action C, following the "A : B" relation. Your answer should be a single verb, without further explanation.
Example: throw : fly. aspire : ?
Example solution: attain

Problem: watch : see. throw : ?
Solution: fly
