HESI A2 Reading Comprehension V1 2024

Correct Answer: C

Rationale: The correct answer is C because the author's primary purpose is to inform the reader about how an electrocardiograph reads the electric currents emitted by the heart. This is evident as the essay likely discusses the technical aspects of electrocardiography. Choice A is incorrect because there is no indication of persuasion in the essay. Choice B is incorrect as the focus is not on entertaining but on providing information. Choice D is incorrect as the essay is not about analyzing the differences between specific nodes in the heart.

Correct Answer: C

Rationale: The correct answer is C: Something that is significant but unusual. In the context of the second paragraph, the word 'phenomenon' is used to describe something that is noteworthy and out of the ordinary. It implies that the subject being discussed is unique or remarkable. Choices A, B, and D are incorrect because they do not capture the essence of 'phenomenon' as being both significant and unusual. Option A focuses on being lifeless, B on nonchalant behavior, and D on chemical origin, none of which align with the meaning of 'phenomenon' in this specific 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.

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: A

Rationale: The correct answer is A: Something that is able to resist and be flexible.

Choice B is incorrect as elasticity is not related to being like plastic. Choice C is incorrect as it does not capture the essence of elasticity being about resistance and flexibility. Choice D is incorrect as silliness has no relation to the concept of elasticity.
