I get that the correct answer is to throw a Runtime Exception. But shouldn't "The given code is syntactically incorrect." also be a correct answer? There's nothing syntactically wrong about using an assertion to check input in a public method is there? It's just not an appropriate use of assertions.

You are right but the option says "incorrect". That is why the option is wrong.

Doh! Right. Looks like I need to read the answer choices more carefully. Thanks!
