Task: Text Matching
Input (English): Sent1: If marriage can be redefined to include other arrangements people may want (right now, same-sex couples are trying to do this) then most certainly it can be redefined to include more people in a relationship to have it apply to.
 Sent2: Using the same logic, doesn't giving couples benefits, without marriage, to gay and straight couples, probably hurt polygamists too, and hurt single people who just want to co-habitate, but don't want to register for as a couple?
Output (English): Not similar
