SECTION 1: READING COMPREHENSION (Questions 1-25)
Passages followed by questions testing main idea, details, inference, and
vocabulary in context.
Read the passage below and answer questions 1-5.
The human circulatory system is responsible for transporting oxygen, nutrients,
hormones, and cellular waste products throughout the body. The heart, a
muscular organ about 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 the body's tissues, while veins return oxygen-depleted blood back to the
heart. Capillaries, the smallest blood vessels, facilitate the exchange of oxygen,
carbon dioxide, nutrients, and waste products between blood and tissues. The
circulatory system also plays a vital role in regulating body temperature and
maintaining pH balance.
Question 1
What is the main idea of this passage?
A) The heart is the most important organ in the body
,B) The circulatory system transports substances and maintains homeostasis
C) Arteries and veins have different functions
D) Capillaries are the smallest blood vessels
Answer: B
Rationale: The passage describes the circulatory system's functions: transporting
oxygen, nutrients, and waste, plus regulating temperature and pH. While A, C,
and D are mentioned, they are supporting details, not the main idea.
Question 2
According to the passage, what is the function of capillaries?
A) Pumping blood to the lungs
B) Returning blood to the heart
C) Facilitating exchange between blood and tissues
D) Carrying oxygen-rich blood away from the heart
Answer: C
Rationale: The passage states: "Capillaries, the smallest blood vessels, facilitate
the exchange of oxygen, carbon dioxide, nutrients, and waste products between
blood and tissues."
,Question 3
The word "facilitate" in the passage most nearly means:
A) Prevent
B) Hinder
C) Enable or make easier
D) Delay
Answer: C
Rationale: In context, "facilitate" means to make an action or process easier.
Capillaries enable or make possible the exchange of substances between blood
and tissues.
Question 4
Which conclusion can be drawn from the passage?
A) The circulatory system works independently of other body systems
B) Veins carry blood toward the heart
C) Arteries always carry oxygen-rich blood
D) The heart is the largest organ in the body
, Answer: B
Rationale: The passage states "veins return oxygen-depleted blood back to the
heart." Option C is incorrect because pulmonary arteries carry oxygen-poor blood
to the lungs.
Question 5
The author's tone in this passage is best described as:
A) Persuasive
B) Entertaining
C) Informative and objective
D) Critical
Answer: C
Rationale: The passage presents factual information about the circulatory system
without attempting to persuade, entertain, or criticize; it is purely informative and
objective.
