TASK DEFINITION: We would like you to classify each of the following sets of argument pairs (discussing Gay Marriage)  into either SIMILAR or NOT SIMILAR. A pair of arguments is considered SIMILAR if the arguments are about the same FACET (making the same argument), and is considered NOT SIMILAR if they do not have the same FACET. A FACET is a low level issue that often reoccurs in many arguments in support of the author's stance or in attacking the other author's position.
PROBLEM: Sent1: There is no good reason behind giving marriage benefits to people based on their sex and there are plenty of reasons to do just the opposite.
 Sent2: In the case of same-sex marriage, I can think of no reason why we should not extend the same rights that opposite-sex couples have to same-sex couples (and plenty of reasons why we should).

SOLUTION: Similar

PROBLEM: Sent1: If you wish to argue for gay rights, realize that other things you may not agree with become a lot more possible.
 Sent2: Also, you said that race is an issue of acceptance of another group, but that it is possible to oppose gay marriage while fully accepting gays.

SOLUTION: Not similar

PROBLEM: Sent1: We give married couples marriage benefits TO STRENGTHEN the marriage, because marriage STRENGTHENS society.
 Sent2: If we legalize polygamy, those in polygamous relationships will be able to bestow their marriage benefits on an unlimited number of people while those in monogamous relationships will only be allowed to bestow those benefits on a single person.

SOLUTION:
Not similar
