Passage for Questions 1-4:
The human circulatory system, also known as the cardiovascular system, consists of the
heart, blood vessels, and approximately 5 liters of blood. This remarkable system
transports oxygen, nutrients, hormones, and waste products throughout the body. The
heart, a muscular organ roughly the size of a fist, pumps blood through a network of
arteries, veins, and capillaries. Arteries carry oxygen-rich blood away from the heart to
tissues, while veins return oxygen-poor blood back to the heart. Capillaries, the smallest
vessels, facilitate exchange between blood and tissues. The circulatory system
collaborates with other systems—delivering oxygen from the respiratory system to cells
and carrying waste to the excretory system for removal.
Q1: Which of the following best states the main idea of the passage?
A. The heart pumps blood through arteries and veins
B. Capillaries are the smallest blood vessels in the body
C. The circulatory system transports materials and works with other body systems
D. The human body contains approximately 5 liters of blood
,Correct Answer: C
Rationale: The main idea must encompass the entire passage. Option C captures both
the transport function and the intersystem collaboration discussed. Options A, B, and D
are supporting details that are too narrow. Key Concept: The main idea is the central
point; supporting details provide evidence but don't represent the whole.*
Q2: According to the passage, which statement is accurate?
A. Veins carry oxygen-rich blood to body tissues
B. Arteries return blood to the heart
C. Capillaries connect arteries and veins and allow exchange of substances
D. The circulatory system works independently of other body systems
Correct Answer: C
Rationale: The passage explicitly states capillaries "connect arteries and veins and
facilitate exchange." Option A reverses the function of veins. Option B reverses the
function of arteries. Option D contradicts the passage's discussion of system
collaboration. Key Concept: Verify each option against the text; eliminate
contradictions.*
Q3: The word "collaborates" in the final sentence most nearly means:
A. Competes
B. Works together
C. Functions separately
D. Dominates
,Correct Answer: B
Rationale: "Collaborates" means to work jointly with others. Context clues indicate the
circulatory system works with respiratory and excretory systems. Key Concept: Use
surrounding context to determine word meaning; eliminate antonyms.*
Q4: Which text feature would be most helpful for locating specific information about
blood vessels in a textbook?
A. Title page
B. Table of contents
C. Index
D. Glossary
Correct Answer: C
Rationale: An index alphabetically lists topics with page numbers, making it most
efficient for locating specific information. A table of contents (B) provides chapter
overviews but not detailed topic locations. A glossary (D) defines terms but doesn't
direct to content locations. Key Concept: Different text features serve different
navigation purposes.*
Q5: Read the following sentences:
The experiment yielded unexpected results. _______, the researchers decided to repeat the
procedure to verify their findings.
Which transition word best completes the sentence?
A. However
, B. Consequently
C. Furthermore
D. Nevertheless
Correct Answer: B
Rationale: "Consequently" indicates a result or logical outcome—the researchers
repeated the procedure because of the unexpected results. "However" (A) and
"Nevertheless" (D) indicate contrast. "Furthermore" (C) indicates addition. Key Concept:
Transition words show logical relationships between ideas.*
Q6: Which of the following is a primary source for a research paper on the 1969 moon
landing?
A. A textbook chapter about space exploration
B. A documentary film about NASA
C. Audio recordings of communications between astronauts and mission control
D. An encyclopedia article about the Apollo program
Correct Answer: C
Rationale: Primary sources provide firsthand, original material from the time period.
Audio recordings from the actual event are primary sources. Textbooks (A),
documentaries (B), and encyclopedias (D) are secondary sources that analyze or
interpret primary materials. Key Concept: Primary sources are original; secondary
sources interpret.*
