TASK DEFINITION: We would like you to assess the QUALITY of each of the following argument (discussing Gay Marriage) and determine if the argument is Valid or Invalid. A valid argument is clearly interpretable and either expresses an argument, or a premise or a conclusion that can be used in an argument for the topic of gay marriage. An invalid argument is a phrase that cannot be interpreted as an argument or not on the topic of gay marriage.
PROBLEM: If we want to distinguish between same-sex marriage and opposite-sex marriage, we can simply say, "same-sex marriage" or "opposite-sex marriage".

SOLUTION: Valid

PROBLEM: I think the lack of monogamy problem among gay men stems from the fact that homosexuality has always been hand-in-hand with promiscuity.

SOLUTION: Valid

PROBLEM: And when all the world that we know is following something and everything that we have been taught since the day we were born is being contradicted by this strong innate feeling, it's a staggering feeling.

SOLUTION:
Invalid
