Passage

Forests are among the world’s most valuable resources, both in a narrowly economic sense and in a broader, ecological sense. Besides yielding over 5,000 commercial products that contribute some 2 percent to the world’s total economic production, forests provide recreation, reduce flooding, and prevent soil erosion that clogs rivers with silt. However, oxygen-renewing capacity of forests, the other about the role of forests in preserving biodiversity—merit special scrutiny.

Some consider the tropical rain forests of the Brazilian Amazon region “the lungs of the earth,” claiming that the foliage absorbs so much carbon dioxide and produces so much oxygen that the atmosphere would be depleted of the latter if these forests ceased to exist. But this belief is largely a myth. the trees produced. In net terms, therefore, forests neither produce nor consume oxygen.

Another claim made is that the preservation of biodiversity, the globe’s profusion of plant and animal species, requires a stricter policy to conserve forest, especially tropical rain forest. For one thing, many scientists believe that some tropical rain-forest plant species yet to be discovered may contain agents with unique disease-fighting properties. These diversity—or, at least, that to do so would be a noninstrumental, that is, an intrinsic, good.

Actually, careful review of official statistics suggests that tropical deforestation is not occurring as fast as has often been claimed. Some existing forests, however, do consist of commercial plantations, of which some people are highly critical. Such plantations tend to contain significantly fewer plant and animal species than natural forest. However, since of official data shows that plantations make up just 3 percent of the world’s forest area.

What this question is testing

Main Point

Your task

Common trap

Answers that are true but too narrow (a single paragraph) or too broad (beyond the passage's scope).

1.

Which one of the following most accurately states the main point of

Answer choices

  1. Correct87% picked this

    Arguments concerning the economic use of forests must be carefully examined before reasonable policy decisions

    Why this is right

    This is a pretty lame main point, because rather than "these arguments must be carefully examined", we should be hearing, "I've carefully examined these arguments, and they don't hold up". But it ends up being our best available answer. We know that the last couple sentences of the 1st paragraph are the Framing Ideas that the 2nd, 3rd, and 4th paragraphs are unpacking. This answer sounds like the sentence in the 1st paragraph where we got the holy Purpose Pivot (but, yet, however, recently): If well-grounded policy decisions are to be made concerning which forests must be preserved and how much forest must be preserved, policy makers should have a comprehensive understanding of the arguments for and against the use of forests. The rest of the passage focuses on two specific claims and tries to provide context for a fuller understanding of those issues.

  2. Too Strong: insignificant2% picked this

    The dangers posed to biodiversity by deforestation, although considerable, are insignificant when compared to those posed by ill-considered attempts at

    This sounds way too harsh. The author is diplomatically debunking a couple alarmist claims that go into the forest debate. But this answer makes it sound like the author is sneering at attempts to have stricter regulation, saying "The considerable dangers posed by deforestation are tiny when compared to the huge dangers posed by ill-conceived attempts to more strictly regulate forests". The author never discussed any huge dangers posed by more regulation.

  3. Too Narrow: only 2nd claim8% picked this

    Careful review of official statistics shows that neither deforestation nor displacement of natural forest by commercial plantations is proceeding as

    This answer only deals with the content of paragraph 3 and 4. It doesn't have a way to wrap its arms around the discussion about forests being the lungs of the earth. The author set out to debunk two claims that are ill-informed contributions to the debate over forest regulation. This answer only deals with the second claim.

  4. Wrong Emphasis / Too Narrow1% picked this

    While there is some hope that tropical rain forests might yield information that will result in new medicines, the primary reason for

    At the end of the 3rd paragraph, the author is saying that one can make a case that we should preserve forests' biodiversity for the sake of our own benefit (medical applications) or for the sake of the fact that nature made these diverse forests and it would be wrong for us to destroy it. The author never indicates that she agrees more with one rationale than the other, whereas this answer makes it seem like she is strongly on the side of defending forests on moral grounds. In addition to never committing to this position, this certainly isn't the main focus of the passage.

  5. Out of Scope: ineffective way3% picked this

    Assuming biodiversity is an instrumental good, imposing stricter regulation on the establishment of commercial plantations is an ineffective way

    The author never discusses the specific effects of stricter regulation in order to argue that this method is an ineffective way of preserving biodiversity. The author is just saying the urge to impose stricter regulations is based in part on two claims that merit special scrutiny, since they both seem wrong or overblown.
