Task: Text Matching
Input (English): Sent1: If there are cases where we can not determine what sex a person is, how can we determine if they are homosexual or not?
 Sent2: I have seen only two arguments (and one of them is restated here) for gay marriage to not be a thing: we have to protect the sanctity of marriage or marriage should only be for people who can reproduce.
Output (English): Not similar
