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: When marriage laws were first written the idea of including gays probably never even occurred to anyone.

SOLUTION: Valid

PROBLEM: If one does not, then the correct path is to seek to amend the Constitution to exclude gay citizens, and this the GOP has repeatedly sought to do.

SOLUTION: Valid

PROBLEM: What I do about slavery, and the colored race, I do because I believe it helps to save the Union; and what I forbear, I forbear because I do not believe it would help to save the Union.

SOLUTION:
Invalid
