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: In either case, it is a weak argument for the RC being anti-gay, since homosexual sex is just one of a hundred or so "risk factors" that disqualify one from donation.

SOLUTION: Valid

PROBLEM: It's moral for women to remain silent, not teach, and never have authority over men?

SOLUTION: Invalid

PROBLEM: Several calls to Mark Potok of the Southern Poverty Law Center seeking comment for this article were not returned by press time.

SOLUTION:
Invalid
