You will be given a definition of a task first, then an example. Follow the example to solve a new instance of the task.
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.

It is usually just as religiously important to same-sex couples to be married as it is for opposite-sex couples, and no one should be able to tell those people that the government cannot recognize their relationship.
Solution: Valid
Why? It is a clear argument that supports gay marriage by saying it is as religiously important as opposite-sex marriage.

New input: A valid argument against incestuous marriage would not have as its only premise "Marriage is defined as a legal bond between a man and a woman who are not x-apart related."
Solution:
