Section 1: Reading Comprehension
Question 1
Passage: "Hand hygiene is the single most effective method for preventing
healthcare-associated infections. Despite this, studies show that compliance
among healthcare workers averages only 40-50%."
According to the passage, what is the most effective method for preventing
healthcare-associated infections?
A) Wearing sterile gloves at all times
B) Isolating infected patients
C) Performing proper hand hygiene
D) Using strong disinfectants on surfaces
Rationale: The passage explicitly states that "hand hygiene is the single most
effective method for preventing healthcare-associated infections." Options A,
B, and D are not mentioned in the passage as the most effective method.
Question 2
Passage: "In 1928, Alexander Fleming returned from vacation to find a mold
contaminating a bacterial plate and killing the surrounding Staphylococcus
bacteria."
The discovery described is best categorized as:
,A) Accidental
B) Theoretical
C) Systematic
D) Computational
Rationale: Fleming's observation was unplanned ("returned from vacation to
find"), which fits the description of accidental. The other options imply
deliberate hypothesis-testing or modeling, which did not occur.
Question 3
Passage: "Urban green roofs reduce ambient temperatures by
evapotranspiration, lowering HVAC costs and decreasing energy expenditures."
Which inference is valid based on the passage?
A) All buildings must install green roofs
B) Green roofs decrease energy expenditures
C) HVAC systems become obsolete with green roofs
D) Evapotranspiration increases indoor humidity
Rationale: The text explicitly links green roofs to "lowering HVAC costs,"
which implies decreased energy spending. Option A is too extreme ("must"),
and Option C is unsupported by the passage.
Question 4
Passage: "Children who read five books over summer maintain vocabulary
gains, whereas non-readers lose 20% of progress."
The author's purpose is primarily to:
A) Entertain parents with anecdotes
B) Persuade educators to shorten summer break
C) Inform about literacy retention strategies
D) Argue against standardized testing
Rationale: The passage provides data to encourage summer reading, which
aligns with informing readers about literacy retention strategies. The other
options are outside the scope of the passage.
,Question 5
Passage: "The word 'unified' in the context of plate tectonics theory means
bringing together disparate geological phenomena."
The word "unified" most nearly means:
A) Contradicted
B) Integrated
C) Questioned
D) Predicted
Rationale: "Unified" signifies bringing together, which is synonymous with
"integrated." The other options do not convey synthesis or combining.
Question 6
Passage: "Despite rigorous training, long-haul pilots experience circadian
disruption."
Which conclusion is supported by the passage?
A) Training eliminates jet lag
B) Circadian disruption persists for pilots
C) Short flights cause more disruption than long ones
D) Technology has solved fatigue issues
Rationale: The phrase "Despite rigorous training... experience circadian
disruption" implies that the disruption persists. Option A is directly refuted,
while Options C and D are unmentioned.
Question 7
Passage: "Municipal water fluoridation lowers dental caries incidence by 25%."
The passage relies on which evidence type?
A) Anecdotal
B) Statistical
C) Expert opinion
D) Historical precedent
Rationale: The passage cites a specific numerical percentage (25%), which is a
statistical form of evidence. Anecdotal evidence would involve personal
, stories, expert opinion would cite authorities, and historical precedent would
reference past events.
Question 8
Passage: "Inflammation is a protective process triggered by injury, involving
vessel dilation and white blood cell migration."
What is the primary purpose of the inflammatory response?
A) To permanently repair damaged tissue within minutes
B) To prevent all types of infections from entering the body
C) To protect the body by initiating a localized response to injury
D) To increase carbon dioxide levels in the blood
Rationale: The passage states that inflammation is a "protective process"
triggered by injury. Option A is incorrect because repair is not immediate or
permanent; Option B is too absolute ("prevent all"); Option D is unrelated to
inflammation.
Question 9
Passage: "Vessels dilate and become more permeable, allowing white blood
cells to migrate to the affected area."
In the passage, the word "permeable" most nearly means:
A) Closed off
B) Allowing substances to pass through
C) Thick and rigid
D) Inflamed and painful
Rationale: The passage states vessels become more permeable, "allowing
white blood cells to migrate." Context clues indicate permeability means
letting things pass through. Options A and C are opposites; Option D
describes a symptom, not a vessel property.
Question 10
Passage: "Compliance with hand hygiene guidelines averages only 40-50%
despite clear CDC recommendations."
What can be inferred about healthcare worker compliance?
