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: My arguments are based on my reasoned opinion that to be a truly free and equal society, acting according to our founding principles in the Declaration of Independence, we should grant equal marriage rights to same-sex couples.

SOLUTION: Valid

PROBLEM: So what compelling reason does the government have for allowing gay marriage and NOT allowing incestuous marriages?

SOLUTION: Valid

PROBLEM: We as a nation have many times perceived that it did some bad things, or simply needed a bit of tweaking here and there, and hence we changed the Constitution to accomplish those mostly worthy ends.

SOLUTION:
Valid
