1. Based on the information given, what is spelunking?

• A. exploring inside a cave
• B. an outdoor adventure
• C. walking with a double stroller
• D. a hot, summer day

Correct answer: A

Rationale: The passage describes spelunking as 'hit the road towards it as soon as you can' and 'discover the wonders of the cool, dark earth even while it is weltering hot in the outside world.' This indicates that spelunking involves exploring inside a cave, making option A, 'exploring inside a cave,' the correct answer. Choices B, C, and D are incorrect as they do not align with the description of spelunking provided in the passage.

2. In which of the following situations is the inclusion of a citation necessary?

• A. The author is stating an opinion about a new biography of Abraham Lincoln.
• B. The author is describing a trip to Abraham Lincoln's birthplace.
• C. The author is quoting another author's opinion about a new biography of Abraham Lincoln.
• D. The author is describing a play she saw about Abraham Lincoln.

Correct answer: C

Rationale: The correct answer is C. A citation is required when directly quoting another author's opinion to give credit and avoid plagiarism. Choices A, B, and D do not necessitate citations as they involve the author's own opinion, personal experience, and description of a play, respectively, without directly quoting another source.

3. Why do cicadas make a buzzing sound?

• A. To orient via echolocation
• B. To attract a mate
• C. To locate a food source
• D. To ward off predators

Correct answer: B

Rationale: Cicadas make a buzzing sound primarily to attract a mate. This sound is a mating call produced by the males to attract females for reproduction. While echolocation is used by some animals like bats for navigation, cicadas do not use buzzing for orientation. Buzzing is not related to locating a food source or warding off predators in the case of cicadas.

4. Which of the following is NOT a major function of the respiratory system in humans?

• A. It provides a large surface area for gas exchange of oxygen and carbon dioxide.
• B. It helps regulate the blood's pH.
• C. It helps cushion the heart against jarring motions.
• D. It is responsible for vocalization.

Correct answer: C

Rationale: Option C, 'It helps cushion the heart against jarring motions,' is NOT a major function of the respiratory system in humans. The primary functions of the respiratory system include gas exchange, regulation of blood pH, and vocalization. The respiratory system does not play a role in cushioning the heart; that function is primarily carried out by the pericardium and other protective structures around the heart. Choices A, B, and D are major functions of the respiratory system in humans. Choice A refers to the respiratory system's role in gas exchange, Choice B highlights its involvement in regulating blood pH, and Choice D points out its responsibility for vocalization.

5. What is the formula to calculate kinetic energy?

• A. Kinetic Energy = Mass × Velocity
• B. Kinetic Energy = Force × Distance
• C. Kinetic Energy = Power × Time
• D. Kinetic Energy = Potential Energy ÷ Time

Correct answer: A

Rationale: Kinetic energy is the energy an object possesses due to its motion. The formula to calculate kinetic energy is KE = 0.5 × mass × velocity^2, which can also be written as KE = mass × (velocity)^2. Therefore, the correct formula is Kinetic Energy = Mass × Velocity. Choice B is incorrect because it represents the work formula. Choice C is incorrect as it represents the formula for work done. Choice D is incorrect as it does not accurately represent the formula for calculating kinetic energy.
