IMO (A)
Stimulus is saying: average rate of violent gun crime increased. 50% higher from other states that do not have strict gun control laws. therefore, to reduce gun crime -> remove gun control laws.
we want to weaken the argument
(A) weakens it. says, even though the AVG rate ^, the ANNUAL rate is lower in states with the laws. So to reduce annual gun crime > keep the laws
(B) strengthens the argument in stimulus
(C) has nothing to do with the stimulus
(D) this one might trick you. but the annual rate in NON-VIOLENT CRIMES....the stimulus talks about VIOLENT crimes.
(E) Again has nothing to do with the conclusion of stimulus
