SECTION 1: READING COMPREHENSION
Passage 1: The Role of Sleep in Healing
Sleep is a vital, often neglected, component of every person's overall health and well-being. Sleep is
important because it enables the body to repair and be fit and ready for another day. Getting adequate
rest may also help prevent excess weight gain, heart disease, and increased illness duration. During
sleep, the body produces cytokines, proteins that target infection and inflammation, effectively creating
an immune response. Therefore, when sleep is deprived, the production of these protective cytokines
decreases, as does the production of infection-fighting antibodies and cells. Individuals who do not get
quality sleep or enough sleep are more likely to get sick after being exposed to a virus, such as the
common cold. Furthermore, the recovery time from illness is often prolonged in those who do not get
adequate rest.
Q1: What is the main idea of the passage?
A. Cytokines are proteins that target infection.
B. Sleep deprivation leads to weight gain.
C. Adequate sleep is essential for immune function and overall health.
D. Viruses like the common cold are prevented by sleep.
Correct ANSWER: C
,Rationale: The passage discusses the various ways sleep contributes to health, specifically focusing on
the immune system, healing, and disease prevention. Option A is a detail mentioned in the passage but
does not capture the overall main idea. Option B is mentioned as a secondary point but is not the
central focus of the passage. Option D is too specific and misrepresents the passage, which states that
sleep helps the body fight viruses rather than preventing them entirely.
Q2: According to the passage, what is the function of cytokines?
A. They help individuals gain weight.
B. They target infection and inflammation.
C. They cause sleep deprivation.
D. They prevent heart disease.
Correct ANSWER: B
Rationale: The passage explicitly states that cytokines are "proteins that target infection and
inflammation." Option A is incorrect as cytokines are not associated with weight gain. Option C is
incorrect because cytokines are produced during sleep, not causing deprivation. Option D is incorrect
because while sleep prevents heart disease, cytokines specifically target infection and inflammation.
Q3: What happens to cytokine production when an individual is sleep deprived?
A. It increases significantly.
B. It remains unchanged.
C. It decreases.
,D. It doubles.
Correct ANSWER: C
Rationale: The passage states that "when sleep is deprived, the production of these protective cytokines
decreases." Option A is the opposite of what the passage indicates. Option B contradicts the passage.
Option D is not supported by any information in the passage.
Q4: Which of the following is NOT mentioned as a benefit of adequate sleep?
A. Prevention of excess weight gain
B. Reduction of heart disease risk
C. Improved memory function
D. Decreased illness duration
Correct ANSWER: C
Rationale: The passage mentions prevention of weight gain, reduction of heart disease, and decreased
illness duration. Improved memory function is not discussed in this passage. Options A, B, and D are all
explicitly mentioned as benefits of adequate sleep.
Q5: The passage suggests that individuals who do not get enough sleep are:
A. Less likely to get sick
B. More likely to get sick after virus exposure
, C. Unable to produce antibodies
D. Completely immune to the common cold
Correct ANSWER: B
Rationale: The passage states that individuals who do not get quality sleep or enough sleep are "more
likely to get sick after being exposed to a virus." Option A is the opposite of what the passage suggests.
Option C is too extreme; the passage says production decreases, not that it stops entirely. Option D
contradicts the passage completely.
Q6: The word "prolonged" in the last sentence most nearly means:
A. Shortened
B. Extended
C. Prevented
D. Ignored
Correct ANSWER: B
Rationale: "Prolonged" means extended or lengthened. In context, recovery time from illness is
extended in those who don't get adequate rest. Option A is the opposite meaning. Option C and D do
not relate to the length of time.
Passage 2: The Water Cycle
The water cycle, also known as the hydrologic cycle, describes the continuous movement of water on,
above, and below the surface of the Earth. Water can change states among liquid, vapor, and ice at
