This passage is adapted from "Yellowstone Wolf Project: Annual Report, 2012."

Yellowstone National Park northern range elk-wolf populations, 1995–2010.

1. The passage suggests that which of the following previous beliefs about wolf packs may be inaccurate?

  • A. The sizes of elk populations and wolf populations are related to one another.
  • B. Wolves are part of the naturally functioning ecosystem.
  • C. Predator control efforts can be extremely effective.
  • D. Wolf packs are too dangerous to be left alive.

2. As used in line 14, "native" most nearly means

  • A. inborn.
  • B. constitutional.
  • C. indigenous.
  • D. canine.

3. As used in line 28, "harvested" most nearly means

  • A. gathered.
  • B. killed.
  • C. acquired.
  • D. grown.

4. Which of the following, if true, would most weaken the author's argument in lines 30-32?

  • A. Predation studies on Delta and Bechler packs done by a separate research group show their diet to consist almost entirely of elk.
  • B. Northern packs that occasionally roam into the park's interior have more stable populations than other northern packs.
  • C. In 2013 a pack of coyotes infected with mange migrated into the park and wolf populations soon declined.
  • D. Studies of bison populations are incomplete and are known to over-estimate the number of bison living in YNP.

5. The fifth paragraph (lines 57-85) most strongly suggests which of the following about the predation data gathered in 2012?

  • A. The wolves are primarily responsible for the drops in the elk population.
  • B. The predation data is incomplete.
  • C. Most of the packs were observed by ground teams.
  • D. Researchers documented characteristics of only wolf prey.

6. Which choice provides the best evidence for the answer to the previous question?

  • A. Lines 59-63 ("Wolf packs…mid-December")
  • B. Lines 63-68 ("The Blacktail…session")
  • C. Lines 71-73 ("The Delta…located")
  • D. Lines 78-85 ("During…sites")

7. The passage suggests that the relationship between elk and wolf populations is best characterized as which of the following?

  • A. The size of the northern wolf packs is the major limiting factor on elk populations.
  • B. The superior hunting tactics that wolves possess are one of many factors that affect elk populations.
  • C. The sizes of wolf and elk populations affect one another.
  • D. The size of the elk population is the major limiting factor on the wolf packs.

8. Which choice provides the best evidence for the answer to the previous question?

  • A. Lines 25-27 ("Wolf numbers…YNP")
  • B. Lines 51-52 ("Wolf packs…2012")
  • C. Lines 57-59 ("Wolf-prey…sites")
  • D. Lines 90-94 ("In addition…severity")

9. The author references weather (lines 94-96) primarily in order to

  • A. illustrate one possible logistical difficulty in tracking wolves in YNP.
  • B. provide a reason for the improved quality of elk food.
  • C. argue for the design of a new predation study in YNP.
  • D. provide additional information relevant to the decline of elk.

10. Which claim about wolf and elk populations studied by the National Park Service is supported by the graph?

  • A. Currently, elk populations out-number wolf populations in YNP.
  • B. Since wolf reintroduction in YNP, elk populations have only decreased.
  • C. Wolf populations are highest when elk populations are lowest.
  • D. Currently, elk populations and wolf populations are about the same.
