Teacher:We would like you to classify each of the following sets of argument pairs (discussing Death Penalty)  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.
Teacher: Now, understand the problem? Solve this instance: Sent1: Prison guards, other inmates, etc., are all potential victims of lifers behind bars.
 Sent2: It is also possible for an innocent person to be sentenced to life in prison without the possibility of parole, but nobody is making the argument to stop sending people to prison.
Student:
Not similar
