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: Those who feel that same sex marriage should not be allowed are free to get married and divorced as many times as they like.

SOLUTION: Valid

PROBLEM: I also doubt I've argued that a hospital shouldn't be required to be decent, or that 'visiting a lawyer' would mean one was 'all set' in every way.

SOLUTION:
Invalid
