In my opinion, the answer to this question hinges on how fast you identify that it is "one species" that the town planners seem intent on planting.

C. A number of trees from one of the species widespread in Thomasville 20 years ago reached the end of their natural life span in the intervening period.


The goal of the "proposal" is to "assure downtown Thomasville of an abundant tree population 20 years from now." This answer choice tells us that a number of one particular species of tree died off naturally within the past twenty years. Is this because that kind of tree generally lives less than twenty years? Or because the trees were all planted at the same time more than twenty years ago? The first option would strengthen the proposal, while the second would call the data into question. We are not given enough information to determine the reason behind this statement, and therefore its effect on the strength of the proposal.

What we do know is that other types of trees have survived for the past twenty years, and that the proposal advocates planting those trees. So, answer choice (C) does not significantly undermine the proposal and we can throw it out.

Dear GMATNinja

Can you elaborate more on the highlighted part? I do not understand how the first strengthen and the second weaken.
Thanks

We cannot tell whether choice (C) undermines the claim that the tree planting proposal will assure an abundant tree population.

We could come up with a variety of hypothetical situations consistent with choice (C), for example:

    1) Maybe the trees mentioned in (C) -- those that "reached the end of their natural life span in the intervening period" -- were all relatively young when they died. And perhaps because a bunch of those wimpy trees died in the intervening period, that species did not have the best survival record. So it is possible that, given (C), Thomasville ruled out a wimpier species in favor of a more durable one. Great!

    2) But maybe the trees mentioned in (C) were actually a bunch of very old, durable trees that all just happened to reach the end of their natural life spans during the intervening period. And perhaps because a bunch of those strong/durable trees died in the intervening period, Thomasville decided not to plant that species. So it is possible that, given (C), Thomasville ruled out what may have been the most durable tree available. Bummer!

Then again, choice (C) only refers to "a number of trees." Is that a significant number? We have no idea. Maybe (C) only affects a few outliers and wouldn't affect the data analysis or the claim one way or the other.

The bottom line is that we have no reason to believe that (C) undermines the claim. As explained in my last post, (E) clearly undermines the claim. So, (E) is a much better choice than (C).
