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: As a gun-owner and/or strong 2nd Amendment advocate, its importance cannot be overstated, and I do believe it has the potential to render a slew of local, state and federal laws null and void.

SOLUTION: Valid

PROBLEM: What about the fact that the UK feels the need to ban knives and toy guns now?

SOLUTION: Valid

PROBLEM: One can examine 19th century legal treates and find "When words of the enacting clause are clear and positive, recourse must not be had to the preamble."

SOLUTION:
Valid
