HESI A2 Reading Comprehension V1 2024

Correct Answer: B

Rationale: The correct answer is B because it accurately summarizes the passage by mentioning the role of the cardiovascular system in regulating blood pressure through baroreceptors, chemoreceptors, and the kidneys. The other choices are incorrect because they either focus on specific organs like the heart and kidneys (A), or only mention one aspect of blood pressure regulation (C and D). B provides a comprehensive summary that includes all key elements mentioned in the passage.

Correct Answer: A

Rationale: The correct answer is A: requiring expert knowledge. In the fourth paragraph, the word 'technical' is used in the context of needing specific expertise or skill. The term 'technical' often refers to specialized knowledge or proficiency in a particular field. In this case, the text suggests that a certain level of expertise is necessary to understand or perform the task mentioned. Explanation for why the other choices are incorrect: B: Incomplete - This choice does not align with the context in the paragraph. The word 'technical' does not imply incompleteness, but rather a need for specialized knowledge. C: Foreign - The word 'technical' does not indicate something foreign or unfamiliar, but rather something requiring expertise. D: Plagiarized - This choice is unrelated to the meaning of 'technical' in the context. 'Plagiarized' refers to copying someone else's work without permission, which is not relevant to the paragraph's discussion of expertise.

Correct Answer: A

Rationale: The correct answer is A: call into service. In the context of the second paragraph, 'enlist' means to join or sign up for a particular cause or service. This is evident from the sentence mentioning individuals joining the army. Choice B, write down, is incorrect because 'enlist' doesn't refer to simply writing something. Choice C, send away, is incorrect as it implies the opposite meaning of 'enlist.' Choice D, put across, is also incorrect as it does not capture the idea of joining or signing up as 'enlist' does.

Correct Answer: B

Rationale: The correct answer is B because sound waves with a lower pitch have a longer wavelength, which means the waves are farther apart. In sound waves, pitch is determined by the frequency, and lower pitch corresponds to lower frequency and longer wavelength. Therefore, waves that are farther apart have a lower pitch. A: Waves that are closer together have a higher pitch. C: The distance traveled by the waves is not directly related to pitch. D: The distance traveled by the waves does not determine the pitch; it is the wavelength that matters.
