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: There have also been no scientifically documeted cases of gays changing their sexual orientation anymore than straights becoming gay.

SOLUTION: Valid

PROBLEM: The usual reason given for banning first-cousin marriage is because there is a risk of offspring of first cousins having biological problems.

SOLUTION: Valid

PROBLEM: And once they accomplish that special right, according to the American legal process, every other non traditional marriage interest will have a precedent setting case law in which to justify their own reason for having a non traditional marriage.

SOLUTION:
Valid
