TASK DEFINITION: We would like you to classify each of the following sets of argument pairs (discussing Gun Control)  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.
PROBLEM: Sent1: ATF then obtains the sale records which every FFL dealer is required to maintain for every firearm and learns when the gun was received by the dealer and when and to whom the particular gun was sold.
 Sent2: To purchase a firearm in a commercial shop, one needs to have a Waffenerwerbsschein (weapon acquisition permit).

SOLUTION: Not similar

PROBLEM: Sent1: Their argument is hardly valid, they want to stop the selling of firearms to people because they think it will decrease the crimes and school shootings along with other dangers that are caused by guns.
 Sent2: So if its cause people in high crime areas want to buy guns for protection then why do they only want protection against gun murders but not other crimes.

SOLUTION: Not similar

PROBLEM: Sent1: To inact a law that makes a crime of illegal gun ownership has no effect on criminal ownership of guns.
 Sent2: If this is the case, then gun laws have a provable effect on how 'armed' criminals are - more gun control = less gun-carrying criminals, fact.

SOLUTION:
