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: Not only will the criminals still have access to guns, but they will also have the added knowledge that either the person they intend to rob does not have a gun or they are breaking the law.

SOLUTION: Valid

PROBLEM: That means the federally licensed dealers who maintain the current sales records, would have to keep a much greater number of sales records than ever before.

SOLUTION:
Valid
