Part 1. 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.
Part 2. Example
Sent1: Therefore, people will think twice before they choose to commit a crime and also, the death penalty has been proven to deter the crime rate. 
 Sent2: i think the death penalty should be abolished because some people are sentenced to deathfor a crime they might have not committed.
Answer: Not similar
Explanation: The two arguments are talking about totally different things. The first one says we should have death penaly since it can deter the crime rate, and the second says we should abolish death penalty since people may not have committed the crime they are accused of.
Part 3. Exercise
Sent1: So your argument is that if the death penalty was cheaper than life in prison it would have the advantage of being cheaper than life in prison.
 Sent2: Life imprisonment without parole is more effective than execution, and it is cheaper.
Answer:
Not similar
