Teacher: We would like you to assess the QUALITY of each of the following argument (discussing Death Penalty) and determine if the argument is Valid or Invalid. A valid argument is clearly interpretable and either expresses an argument, or a premise or a conclusion that can be used in an argument for the topic of death penalty. An invalid argument is a phrase that cannot be interpreted as an argument or not on the topic of death penalty.
Teacher: Now, understand the problem? If you are still confused, see the following example:
The fact that you do not want to donate to these poor, needy people only shows me that you really do not care about the embryos
Solution: Invalid
Reason: It is not an argument on the topic of death penalty.

Now, solve this instance: If revenge is comparable to justice, doesn't it make more sense (at least in economic terms) to allow communities to kill the people who've committed murder in any way they choose?
Student:
Valid
