Let G be a simple group and let f : S_n --> G be a

Why is G isomorphic to S_k, for some k =< n ?

Because G is cyclic of order two and n>=2.

Which would make it a trick question.

If that was really the wording of the assigned question then, while
technically not incorrect, I suspect the problem was posed in error.
