The myth persists that in 1492 the Western
Hemisphere was an untamed wilderness and that it was
European settlers who harnessed and transformed its
ecosystems. But scholarship shows that forests, in
(5) particular, had been altered to varying degrees well
before the arrival of Europeans. Native populations had
converted much of the forests to successfully cultivated
stands, especially by means of burning. Nevertheless,
some researchers have maintained that the extent,
(10) frequency, and impact of such burning was minimal.
One geographer claims that climatic change could have
accounted for some of the changes in forest
composition; another argues that burning by native
populations was done only sporadically, to augment the
(15) effects of natural fires.
However, a large body of evidence for the routine
practice of burning exists in the geographical record.
One group of researchers found, for example, that
sedimentary charcoal accumulations in what is now the
(20) northeastern United States are greatest where known
native American settlements were greatest. Other
evidence shows that, while the characteristics and
impact of fires set by native populations varied
regionally according to population size, extent of
(25) resource management techniques, and environment, all
such fires had markedly different effects on vegetation
patterns than did natural fires. Controlled burning
created grassy openings such as meadows and glades.
Burning also promoted a mosaic quality to North and
(30) South American ecosystems, creating forests in many
different stages of ecological development. Much of the
mature forestland was characterized by open,
herbaceous undergrowth, another result of the clearing
brought about by burning.
(35) In North America, controlled burning created
conditions favorable to berries and other fire-tolerant
and sun-loving foods. Burning also converted mixed
stands of trees to homogeneous forest, for example the
longleaf, slash pine, and scrub oak forests of the
(40) southeastern U.S. Natural fires do account for some of
this vegetation, but regular burning clearly extended
and maintained it. Burning also influenced forest
composition in the tropics, where natural fires are rare.
An example is the pine-dominant forests of Nicaragua,
(45) where warm temperatures and heavy rainfall naturally
favor mixed tropical or rain forests. While there are
extensive pine forests in Guatemala and Mexico, these
primarily grow in cooler, drier, higher elevations,
regions where such vegetation is in large part natural
(50) and even prehuman. Today, the Nicaraguan pines
occur where there has been clearing followed by
regular burning, and the same is likely to have occurred
in the past: such forests were present when Europeans
arrived and were found only in areas where native
(55) settlements were substantial; when these settlements
were abandoned, the land returned to mixed
hardwoods. This succession is also evident elsewhere
in similar low tropical elevations in the Caribbean and
Mexico.

1. Which one of the following most accurately expresses the main idea of the passage?
(A) Despite extensive evidence that native populations had been burning North and South American forests extensively before 1492, some scholars persist in claiming that such burning was either infrequent or the result of natural causes.
(B) In opposition to the widespread belief that in 1492 the Western Hemisphere was uncultivated, scholars unanimously agree that native populations were substantially altering North and South American forests well before the arrival of Europeans.
(C) Although some scholars minimize the scope and importance of the burning of forests engaged in by native populations of North and South America before 1492, evidence of the frequency and impact of such burning is actually quite extensive.
(D) Where scholars had once believed that North and South American forests remained uncultivated until the arrival of Europeans, there is now general agreement that native populations had been cultivating the forests since well before 1492.
(E) While scholars have acknowledged that North and South American forests were being burned well before 1492, there is still disagreement over whether such burning was the result of natural causes or of the deliberate actions of native populations.

Explanation
1. Which one of the following most accurately expresses the main idea of the passage?
Explanation
The only choice properly reflecting Topic, Scope, and Purpose is (C), which correctly characterizes the passage as presenting—in rebuttal to paragraph 1’s scientists—”evidence of the frequency and impact of” native Americans’ forest burning.
(A) presents the main body of the text (44 lines) in a subordinate “Despite” clause, and gives pride of place to paragraph 1 only, as if the author were in sympathy with the “persistent scholars.”
(B) and (D) both fail because they fail to even mention the passage’s Scope (forest burning), falling back on weaker, broader words like “alteration” and “cultivation.” Also, “unanimously agree” (B) and “general agreement” (D) both contradict the “persistence of the myth” (line 1) that the pre-Columbian wilderness was untamed.
(E) focuses on a small question that the author in fact answers quite convincingly—yes, it was deliberate—as he goes on to his broader interest in the burnings’ impact.
