TASK DEFINITION: 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.
PROBLEM: Sent1: Once the danger is gone killing a person is simply murder.
 Sent2: This process is needed in order to ensure that innocent men and woman are not executed for crimes they did not commit, and even with these protections the risk of executing an innocent person can not be completely eliminated.

SOLUTION: Not similar

PROBLEM: Sent1: It costs far more to execute a person than to keep him or her in prison for life.
 Sent2: First, it is more expensive than sentencing someone to life in prison.

SOLUTION: Similar

PROBLEM: Sent1: So what does he have to do with a debate like this about murderers and the death penalty?
 Sent2: If the same murderer had been given the death penalty, and never released in the first place, he would not be able to kill again.

SOLUTION:
Not similar
