    No, that's the first law. The second law is F=ma.

    I don't think we're understanding each other. You said:

    "the second law states that unless you push an object, the velocity of that object would not change."

    It's the first law that says that, not the second. The second law is F=ma. The question wants you to explain why F=ma implies that unless you push an object, the velocity of that object would not change. To begin, what would "F" be if you don't push an object?
