HESI A2 Reading Comprehension V1 2024

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: A

Rationale: The correct answer is A because baroreceptors and chemoreceptors are sensory receptors that detect changes in blood pressure and blood chemistry, respectively, and send nerve impulses to the brain to regulate these parameters. This is different from the kidneys, which are responsible for regulating blood volume by controlling the balance of salts, water, and waste removal through the production of urine. Therefore, the major difference lies in the function and location of these systems. Choices B, C, and D are incorrect because they either incorrectly describe the functions of baroreceptors, chemoreceptors, and kidneys or provide irrelevant information about their locations and interactions with other organs.

Correct Answer: A

Rationale: The correct answer is A: To consist of. In the context of the first paragraph, 'composed' refers to the elements or parts making up something. The word implies that something is made up of different components. This is evident as the paragraph discusses how the team is composed of individuals with diverse skills and backgrounds. Explanation of why other choices are incorrect: B: To be uniquely discovered - This does not fit the context of the paragraph which is describing the makeup of a team. C: To be set apart - This does not align with the meaning of 'composed' in the context of being made up of different parts. D: To be surprised - This has no relevance to the meaning of 'composed' in the paragraph.

Correct Answer: C

Rationale: The correct answer is C: disease-causing substances. In the first paragraph, pathogens are referred to as agents capable of causing disease. The term 'pathogens' specifically encompasses various microorganisms like bacteria, viruses, fungi, and parasites that can infect a host and lead to illnesses. Choice A, diseases, is incorrect as pathogens are the causative agents of diseases. Choice B, vaccines, is incorrect as vaccines are used to prevent diseases caused by pathogens. Choice D, foods, is also incorrect as pathogens are not related to foods but are rather disease-causing agents. Thus, the most appropriate interpretation of 'pathogens' in the context of the paragraph is disease-causing substances.
