C) If we can show that something besides the court system may explain the increase in crime we would weaken the argument. The author assumes that there is no other cause. Tackle the choices, looking for another cause besides the allegedly lenient court sentences.
The argument's scope is the crime rate increase in this particular city only. In (A), the fact that white collar crime is also on the rise is more of a strengthener than a weakener. (C) presents an alternative explanation for the increase in crime (reduction in police). As for (B), what if 65 percent of people in the city oppose capital punishment? This provides little insight into why crime has gone up since last year. (D) tells us that numerous judges have been replaced in the last year. It is possible that the new judges are more lenient, but this would only strengthen the author's argument. (E) does not compare one city to another.
(A) This conclusion makes sense only if we assume (A), that the media CEO is the one who decides what to print. If (A) weren't true and this decision were up to someone other than the media CEO, the argument would fall apart. (B) is not relevant.
