incorrect. In the first paragraph, the passage mentions that wolves were regarded as
dangerous and were deliberately exterminated. However, the rest of the passage focuses on
how wolves have been restored to their natural habitat. Therefore, (D) is correct.
C The passage uses the word native to describe species that had existed in particular places
until human interference affected their populations; therefore, the word is being used to
describe animals that originated in or had long inhabited an area. Although (A) might sound
like it could have such a meaning, inborn actually describes factors or traits present at
birth, so (A) is incorrect. Choice (B), constitutional, is used to refer to someone’s physical
or mental condition and is also incorrect. Choice (C), indigenous, means originating in a
specific area, making it the correct answer. Choice (D), canine, can be used to refer to
animals of the dog family, which includes wolves; however, canine is not a synonym for
native, so (D) is incorrect.
B The passage mentions that the wolf hunts harvested the wolves. The word hunt suggests
that the wolves were trapped or killed. The next sentence reinforces this idea by noting that
the number of wolves in the interior declined less, and the paragraph as a whole discusses
the declining wolf population. Therefore, the only answer choice that makes sense is (B),
killed.
A The author’s argument in lines 30–32 is that the wolves in Yellowstone have a more stable
population because they eat bison in addition to elk. Choice (A) proposes that the Delta and
Bechler packs survived without eating much bison, which undermines the author’s theory
that eating bison is what prevented the wolf populations from declining as dramatically
within the park as without. Therefore, (A) is correct. Choice (B) indicates that wolves
entering the park have more stable populations, which agrees with the author’s point that
wolves in the park have a more stable population. Choice (C) says that the population of
wolves in Yellowstone has declined, but the author acknowledges that the population
declined; his point is that the population has declined less in the park than elsewhere.
Therefore, (C) is incorrect. Because (D) does not mention wolves, it cannot be correct.
B The paragraph explains how data on wolf-prey relationships was gathered but makes no
claims regarding what patterns that data revealed, so (A) is not supported by the paragraph
and is incorrect. Because the paragraph mentions a wolf pack for which predation data
could not be gathered, (B) is strongly supported by the content of the fifth paragraph. The
paragraph notes that some of the packs were monitored by radio-tracking, ground teams,
and aircraft, while others were monitored by only aircraft or not monitored at all, so there
is no indication that most of the packs were monitored by ground teams, and (C) is
incorrect. Because it is noted that researchers also documented things like percent
consumption by scavengers, (D) is incorrect. Choice (B) is the correct answer.
C The answer to the previous question is that the predation data is incomplete. Choices (A)
and (B) describe the method of gathering data but do not mention gaps in the data collected.
Therefore, both are incorrect. Choice (C) mentions two packs that were not monitored fully,
which supports the idea that the predation data is incomplete. Therefore, (C) is correct.
Choice (D) describes some of the data gathered without alluding to any gaps in the data.
