1 The main purpose of the passage is to
A) counter the claim that mind-body therapies have no effect on the immune system.
B) inform readers that mind-body therapies can influence immune responses in the body.
C) advance the argument that mind-body therapies have become an increasingly popular alternative.
D) uphold the findings of a previous study about the effect of mind-body therapies on behavior.
2 Based on the passage, behaviors can influence physical health by
A) impacting the body’s immune response
B) reinforcing the body’s reactions to physical stress
C) changing the body’s recovery time during illness.
D) increasing the body’s reception to inflammation.
3 Which choice provides the best evidence for the answer to the previous question?
A) lines 1-5(“Over…practices”)
B) lines 6-8(“According…months”)
C) lines 8-10(“Currently…priority”)
D) lines 15-18(“In… system”)
4 The discussion of “multi-dimensional behavioral therapies” in paragraph 3 (lines 30-42) primarily serves to
A) introduce the claim that integrating mental and physical exercise can have a strong impact on health.
B) provide a specific example of how these kinds of therapy can influence a person’s overall health better than any others.
C) inform readers about the different kinds of therapies they can use to supplement their physical activity.
D) defend the study’s findings regarding the efficacy of mind-body therapies on bolstering the immune system.
5 In line 32, "confer" most nearly means
A) bestow
B) negotiate
C) admit
D) allocate
6 The author implies that the study of mind-body therapies is especially important because
A) there has not previously been a comprehensive study on the connection between MBTs and the immune system.
B) MBTs are a new and unexplored way of helping to regulate moods, behavior, and immune responses.
C) MBTs are becoming an increasingly effective method when combined with regular overall exercise.
D) new findings show that MBTs have a greater impact on overall health and can replace physical exercise.
7 Which choice provides the best evidence for the answer to the previous question?
A) lines 43-49(“To…responses”)
B) lines 49-54(“Indeed…vaccinations”)
C) lines 54-58(“Our…approaches”)
D) lines 58-63(“For…infections”)
8 In line 74, "potent" most nearly means
A) influential
B) vigorous
C) useful
D) stiff
9 How does the graph relate to the passage?
A) It indicates that stress hormones are only loosely linked with physical exercise.
B) It highlights findings that exercise has an impact on lowering stress in the body.
C) It supports the claim that cortisol is closely linked in the body with free fatty acids.
D) It emphasizes the disparity between pure physical exercise and mind-body therapies.
10 According to the graph, the largest decrease in cortisol occurs between
A) 15-30 minutes of exercise.
B) 45-60 minutes of exercise.
C) 60-90 minutes of exercise.
D) 90-120 minutes of exercise.
11 It can reasonably be inferred from the graph that
A) while stress hormones rise sharply at the beginning if exercise, they drop below the initial value after 120 minutes.
B) the benefits of prolonged exercise are minimal at best unless one exercises for longer than 180 minutes.
C) both cortisol and free fatty acid levels largely remain the same if exercising for a duration shorter than 60 minutes.
D) a sustained drop in cortisol is beneficial only when combined with a large increase in free fatty acid levels.
