Mayor: Downtown Rosco Lake is generally a clean area, but the Monday after the Fourth of July weekend, there was twice as much trash in the streets and parks as usual. Since downtown Rosco Lake is a major tourist destination on weekends, it must be the tourists who are littering.

The mayor's argument is most called into question by which of the following, if true?

(A) Usually community volunteers go through downtown on Monday mornings, picking up litter.

(B) There is a certain correlation between tourist traffic and incidents of vandalism in many towns.

(C) During other weekends in July, there were no unusual amounts of litter.

(D) The North Shore lakefront area in Rosco Lake is rarely visited by tourists, and has almost no litter, compared to the South Shore, which is a tourist area, and has lots of rubbish lying around.

(E) The nearby town of Graylord was able to control its litter problem by instituting large fines that could be levied against litterers.

Prethinking : The authors arguments is that the tourists are responsible for heavy littering in Downtown Rosco Lake area. Since it is the fourth of July weekend, may be the locals visited the lake area to see the fireworks and caused the littering.

(A) Usually community volunteers go through downtown on Monday mornings, picking up litter.

This option presents an information that is unrelated the authors argument. If this option is true, then the community volunteers will pick the litter as usual and doesn't have an impact on authors argument. INCORRECT

(B) There is a certain correlation between tourist traffic and incidents of vandalism in many towns.

This presents generic information of all towns and is unrelated to the authors arguments which says tourists caused the heavy littering. INCORRECT

(C) During other weekends in July, there were no unusual amounts of litter.

This aligns with the prethinking. If the local visited the lake area, they would account for the more littering and not the tourists. This weakens the authors argument.

(D) The North Shore lakefront area in Rosco Lake is rarely visited by tourists, and has almost no litter, compared to the South Shore, which is a tourist area, and has lots of rubbish lying around.

The authors argument is specific to fourth of July weekend and this option doesn't provide any information on that. INCORRECT

(E) The nearby town of Graylord was able to control its litter problem by instituting large fines that could be levied against litterers.

The authors argument is specific to fourth of July weekend and this option doesn't provide any information on that. INCORRECT

Hence option C

Mayor's argument is generalizing one-off event as a regular activity.

Probably this question assumes that tourists visit Rosco every weekend and this is why mayor decides that tourists are a source of litter. But option C says that on other weekends there is no litter and hence argument about tourists is weakened

The question doesn't assume that tourists visit Rosco Lake every weekend but it specifically states this before the conclusion. It says "Since downtown Rosco Lake is a major tourist destination on weekends, it must be the tourists who are littering"

Option C is correct as correctly pointed by you for the reason that it clearly points out that there were no unusual amounts of litter on other weekends, hence the tourists who visit the lake on every weekend do not litter the area. Therefore it is not the tourists who are littering, we can speculate who did the littering, but that doesn't matter.

Spasiba,
GyM

P.s. hope you don't mind my Russian, Cheers!

Privet GyMrAT!

Pozhaluista). You are welcome!

When i said "assumed" i meant that major tourist destination on weekends is the same as a place that tourists visit every weekend, not a place known as a destination but without tourists. That's all).

P.S No i don't mind your Russian). Hope to read something new soon). Cheers!

vasuca10 Here is an explanation that I found very helpful. Hope it helps!

The correct answer here is C, because the evidence states that downtown Rosco Lake is a tourist destination on weekends in general, but the conclusion is only addressing one specific weekend. Choice C points out that the causal connection isn't a strong one, because the same result hasn't occurred from the same situation on other weekends. Incidentally, D would be a good choice if this question was asking for a strengthener, since it helps to increase the correlation between tourists and litter. It's common for strengthen/weaken questions to have a wrong answer choice that does the opposite of what it's intended to do, so watch out for that trap!

Whenever you are in a situation that 2 things exist together and argument concludes that x - - - > caused y

If you want to weaken it -
Prove the opposite or an alternate cause of the effect.
( in this question, we have an anternate cause in C. It is not the tourist who did littering, maybe it is the locals)
