TASK DEFINITION: We would like you to assess the QUALITY of each of the following argument (discussing Gun Control) 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 gun control. An invalid argument is a phrase that cannot be interpreted as an argument or not on the topic of gun control.
PROBLEM: That would theoretically work except the fact that more knife murders may occur then and perhaps guns will be brought in illegally to murder people.

SOLUTION: Valid

PROBLEM: I guess you either didnt see or chose to ignore the part about a gun on its own being no more dangerous than popsicle sticks, hence the words on its own.

SOLUTION: Valid

PROBLEM: The people in Mumbai learned that the hard way this year when that handful of terrorists came in and slaughtered several hundred innocent people in a matter of days without any opposition.
