1. What is the writer’s primary purpose in writing this essay?

• A. To inform the reader about the dangers of high blood pressure
• B. To inform the reader how high blood pressure leads to a higher risk of heart attack
• C. To inform the reader how the cardiovascular system regulates blood pressure
• D. To persuade the reader that controlling one’s blood pressure is important

Correct answer: C

Rationale: The primary purpose of the essay is to inform the reader about how the cardiovascular system regulates blood pressure. The essay provides detailed explanations about the components of the cardiovascular system that regulate blood pressure, such as baroreceptors, chemoreceptors, and the kidneys. Choices A and B are incorrect because the essay does not focus on discussing the dangers of high blood pressure or its correlation with a higher risk of heart attack. Choice D is incorrect as the essay does not aim to persuade the reader to control their blood pressure but rather to educate them on the regulatory mechanisms of the cardiovascular system.

2. What does the word 'obligatory' mean in the context of the passage on Daylight Savings Time?

• A. Approved.
• B. Sparse.
• C. Requisite.
• D. Aberrant.

Correct answer: C

Rationale: In the passage, Daylight Savings Time is presented as something that must be done by law, making it a requirement or something obligatory. 'Requisite' fits this meaning. 'Approved' (choice A) does not convey the sense of necessity as 'obligatory' does. 'Sparse' (choice B) means thinly dispersed and does not relate to the context. 'Aberrant' (choice D) means deviating from the norm, which is not applicable in this context.

3. What is the meaning of the word disparate as used in the first paragraph?

• A. Unusual
• B. Diverse
• C. Trivial
• D. Damaging

Correct answer: B

Rationale: "Disparate" means diverse or different. The passage discusses how Lyme disease has various symptoms that mimic other diseases, making it difficult to diagnose.

4. As used in the last sentence of this paragraph, the term 'concomitant' means?

• A. Accompanying
• B. Quiet
• C. Frustrated
• D. Prefer low-pitched tones

Correct answer: A

Rationale: In the provided extract, the term 'concomitant' is used to describe problems associated with alcohol abuse, such as the individual becoming alcoholic, contribution to highway deaths by drunken drivers, and spousal and child abuse. Therefore, in this context, 'concomitant' means accompanying, or going along with something else. The other choices of 'Quiet,' 'Frustrated,' and 'Prefer low-pitched tones' do not align with the meaning of 'concomitant' as used in the paragraph.

5. 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.
