1. Which of the following statements is an opinion related to Barefoot Running?

• A. Running barefoot is natural and advantageous.
• B. The cost of modern running shoes keeps increasing.
• C. Concrete sidewalks are harder than dirt paths.
• D. The arch of the foot gives a spring to the step.

Correct answer: A

Rationale: The statement that "running barefoot is natural and advantageous" reflects a subjective opinion, which cannot be definitively proven or measured objectively. The other statements (B, C, and D) provide factual observations or comparisons that can be validated through evidence, which distinguishes A as the only opinion-based statement.

2. Which sound waves have a higher pitch?

• A. Those waves that are closer together
• B. Those waves that are farther apart
• C. Those waves that travel a long distance
• D. Those waves that travel a short distance

Correct answer: A

Rationale: Sound waves that are closer together have a higher pitch. This is explained by the Doppler Effect, where as a source of sound moves closer to an observer, the waves are compressed, resulting in a higher frequency and a higher pitch. Conversely, when the source moves away, the waves are stretched, leading to a lower frequency and a lower pitch. Therefore, choice A is correct. Choices B, C, and D are incorrect as they do not accurately describe the relationship between sound wave frequency and pitch.

3. How were white elephants regarded by the people of Siam?

• A. If a village elder received a white elephant, the entire village shared in the supply of meat.
• B. White elephants were highly prized as they were very hard workers in the cane fields.
• C. The people of Siam vied for the honor of receiving the king's gift or a white elephant.
• D. White elephants were a financial burden despite being considered sacred.

Correct answer: C

Rationale: The correct answer is C. In the culture of Siam, white elephants were highly regarded as sacred and receiving one as a gift from the king was considered an honor. It was a symbol of prestige and status to receive the king's gift of a white elephant. Option A is incorrect as white elephants were not used for meat supply. Option B is also incorrect as white elephants were not prized for their work but rather for their symbolic value. Option D is partially correct but does not capture the full significance of white elephants in Siam.

4. Which of the following is a conclusion that a reader can draw from this passage?

• A. Humans are not the only mammals that exhibit symptoms when infected by Borrelia burgdorferi.
• B. The life cycle of an uninfected tick includes a dormant phase before the nymph stage, which is not excluded.
• C. Unless a tick feeds on an infected mouse or squirrel, it will not spread Lyme disease.
• D. The combination of fever, headache, and joint pain is not a definite indication of Lyme disease.

Correct answer: C

Rationale: The correct answer is C. The passage clearly states that for Lyme disease to spread, a tick must feed on an infected host, such as a mouse or squirrel. This conclusion can be drawn from the information provided in the extract. Choice A is incorrect because the passage does not specify that humans are the only mammals that exhibit symptoms when infected by Borrelia burgdorferi. Choice B is incorrect as the passage mentions that the life cycle of an uninfected tick includes a dormant phase before the nymph stage, without excluding it. Choice D is incorrect because the passage does not state that the combination of fever, headache, and joint pain is a definitive sign of Lyme disease.

5. Which statement would not be inferred by the reader in the passage about Barefoot Running?

• A. Runners who take their shoes off may face some hazards.
• B. Modern running shoes may increase the odds for injury.
• C. Walking barefoot is good for the muscles and tendons.
• D. Before 1950, even Olympic runners ran barefoot.

Correct answer: D

Rationale: The passage does not imply that Olympic runners specifically ran barefoot before 1950. While it discusses historical context regarding running shoes, the claim about Olympic runners is not substantiated within the text, making D the correct answer. It represents an inference that cannot be drawn from the provided information.
