Here we have a weakening question, as we are introducing a premise which weakens an argument: Which one of the following, if true, could Mark cite to counter evidence offered by Tina?

Our stimulus takes the form of a debate between Mark and Tina about whether paper or plastic-foam cups are more environmentally friendly. Mark begins by telling us that p-f cups contain chlorofluorocarbons, which are bad for the environment, and gives us his conclusion; paper cups are the better option. The LSAT sure loves these tongue-twister chemical compounds! But that’s not all Mark has for us, he further informs us that the production of p-f cups also produces the carcinogen styrene, and the cups never biodegrade. They definitely don’t sound like a great option so far. Let’s see what Tina has to say!

Tina begins by claiming that Mark isn’t properly considering the downsides of paper cups. To be fair to Tina, Mark didn’t really give us an argument about why paper cups are good, he just brought up a bunch of downsides of p-f cups. Tina cites a study from 5 years earlier which concluded that paper cups required much more resources to produce than p-f cups. Even worse, paper cups take more energy to transport. And if that wasn’t enough, the paper mills produce pollution and the cups themselves produce even more when they decay. Wow, this seems like a lose-lose situation! Maybe we should all just switch to glasses? But our job is to weaken Tina’s argument; we want some evidence that will make paper cups look better than p-f cups. Let’s see what the answer choices give us:

Answer Choice (A) This just gives another downside for paper cups!

Answer Choice (B) Our argument is about the actual environmental downsides of the two cup types, and regardless this just supports Tina’s foam cups.

Correct Answer Choice (C) This is the only answer that weakens Tina’s support. If the paper mills use waste wood instead of petroleum, then Tina’s points about the relative resource consumption and mill pollution are less of an issue for Mark.

Answer Choice (D) This weakens Mark’s argument!

Answer Choice (E) Same as A!
