    But this does not actually show it, it just suggest it might be true...

    I told you are correct. All I am saying is that the statement of the question is not worded correctly... This does not change what the answer is.

    Closure says that if you take two whole numbers and add them, you get another whole number. Since those two options both have whole numbers as their arguments, and the result is a whole number, we see closure. The other two options have negative numbers and thus are not even whole numbers and thus are not even in the conversation. :)
