SECTION 1: READING (Questions 1–37)
The Reading section assesses your ability to comprehend, analyze, and
evaluate written passages. Questions cover key ideas and details, craft and
structure, and integration of knowledge and ideas.
Passage 1: The Role of Honeybees in Agriculture
Honeybees are essential pollinators for approximately one-third of the food
crops consumed by humans. These industrious insects transfer pollen
between flowering plants, enabling fertilization and the production of fruits,
vegetables, and nuts. The economic value of honeybee pollination in the
United States alone is estimated at over $15 billion annually.
Despite their importance, honeybee populations have been declining at
alarming rates over the past decade. This phenomenon, known as Colony
Collapse Disorder (CCD), is characterized by the sudden disappearance of
worker bees from a hive, leaving behind the queen and immature bees.
, Page 2 of 59
Scientists have identified multiple factors contributing to CCD, including
pesticide exposure, habitat loss, parasitic mites, and viral infections.
The decline of honeybees poses a significant threat to global food security.
Without adequate pollination, crop yields would decrease dramatically,
leading to higher food prices and reduced nutritional diversity. Farmers and
researchers are working together to develop sustainable solutions, including
planting pollinator-friendly habitats, reducing pesticide use, and breeding
more resilient bee populations.
1. What is the primary purpose of this passage?
• A. To describe the life cycle of honeybees
• B. To persuade readers to become beekeepers
• C. To inform readers about the importance of honeybees and the
threats they face
• D. To compare different types of pollinators
Answer: C. To inform readers about the importance of honeybees and the
threats they face
Rationale: The passage provides factual information about the role of
honeybees in agriculture, the threats they face, and the potential
consequences of their decline. The primary purpose is to inform, not to
persuade or describe.
2. According to the passage, what is Colony Collapse Disorder (CCD)?
• A. The complete destruction of a bee hive by predators
• B. The sudden disappearance of worker bees from a hive
• C. The death of the queen bee
• D. The migration of bees to warmer climates
Answer: B. The sudden disappearance of worker bees from a hive
Rationale: The passage states that Colony Collapse Disorder is
, Page 3 of 59
"characterized by the sudden disappearance of worker bees from a hive,
leaving behind the queen and immature bees."
3. Which of the following is NOT mentioned as a factor contributing to
Colony Collapse Disorder?
• A. Pesticide exposure
• B. Habitat loss
• C. Parasitic mites
• D. Climate change
Answer: D. Climate change
Rationale: The passage lists "pesticide exposure, habitat loss, parasitic
mites, and viral infections" as contributing factors. Climate change is not
specifically mentioned.
4. Based on the passage, which conclusion can be drawn about the
relationship between honeybees and food production?
• A. Honeybees are only important for honey production
• B. Honeybees play a critical role in producing many food crops
• C. Honeybees are becoming more abundant
• D. The decline of honeybees has no effect on food prices
Answer: B. Honeybees play a critical role in producing many food crops
Rationale: The passage states that honeybees pollinate "approximately
one-third of the food crops consumed by humans" and that their decline
"poses a significant threat to global food security."
5. What is the meaning of the word "resilient" as used in the final
sentence?
, Page 4 of 59
• A. Weak and fragile
• B. Able to withstand or recover from challenges
• C. Aggressive and hostile
• D. Slow and inactive
Answer: B. Able to withstand or recover from challenges
Rationale: In the context of "breeding more resilient bee populations," the
word "resilient" means able to withstand or recover from the challenges
(pesticides, disease, habitat loss) that bees face.
6. Which of the following is the best summary of the passage?
• A. Honeybees produce honey and are important to agriculture
• B. Honeybees are vital pollinators whose populations are declining
due to multiple factors, threatening global food security
• C. Colony Collapse Disorder is a mysterious phenomenon that
scientists have not been able to explain
• D. Farmers should stop using pesticides to protect honeybees
Answer: B. Honeybees are vital pollinators whose populations are
declining due to multiple factors, threatening global food security
Rationale: This summary captures the main idea of the passage: the
importance of honeybees, the threats they face, and the consequences of
their decline.
Passage 2: The History of Vaccines
The practice of vaccination dates back centuries, but the modern era of
vaccines began with Edward Jenner's work in the late 18th century. Jenner
observed that milkmaids who had contracted cowpox, a relatively mild
disease, seemed to be immune to smallpox, a deadly disease that had
plagued humanity for millennia. In 1796, Jenner conducted his famous
experiment, inoculating a young boy with cowpox and later exposing him to
