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: If inclusion of same sex couples being allowed to marry is what you call "redefining", then the inclusion of interracial couples would also be a "redefiniton."
Output (English): Not similar
