Marta: There have been complaints about the lack of recreational areas

The simple answer, pankhuriarora28, is that Marta says, "There may be more productive ways of using that land," and this is not the same as saying that the proposed conversion "would be an entirely unproductive use of that land." That is, you cannot equate less productive to unproductive. There can be different levels of productivity, as we often see in machine/rate questions in the Quant portion of the exam. In general, you should be wary of extreme or definitive language—e.g., best, never, always—since it is easier to debate than cautious language—e.g., may, could, in some cases. I will admit that I paused myself when I came to promptly dismissed in (D), but I was only hesitant about the adverb. In the end, we have to get behind (D) because Arthur makes it clear that he perceives Marta to have passed a hasty judgment on the matter when he says, "we should not dismiss this proposal for walking trails without further consideration."

An effective approach to CR questions is to adopt a linear thinking strategy. The more you stick to the words on the screen, the harder your eventual answer will be to argue against; the more interpretive you get, the less likely you will be to answer correctly.

I hope that helps. Good luck with your studies.
