Reading Comprehension HESI A2

1. Why is an unwanted gift called a white elephant?

A. It is a good gift to give at the party
B. Gifts are never unwanted
C. Siam's rulers punished with the gift
D. It is rare to get an unwanted gift

Correct answer: C

Rationale: The term 'white elephant' originated from the practice of the kings of Siam (now Thailand) giving rare and sacred white elephants as gifts. These white elephants were highly prestigious but also very expensive to maintain, causing financial burdens on the recipients. The kings of Siam used white elephants as a punishment for those who displeased them. The recipients were required to care for the white elephant in a grand style, resulting in financial liabilities that could make them impoverished. Over time, the term 'white elephant' evolved to describe any valuable item that is burdensome or unwanted. Therefore, choice C is correct. Choices A, B, and D are incorrect because they do not accurately explain the origin and meaning of the term 'white elephant' in the context of unwanted gifts.

2. What is stated in the passage about the Olympic Games?

A. The Olympic Games are held every four years.
B. The Olympic Games are often postponed.
C. The Olympic Games are held only in leap years.
D. The Olympic Games only involve certain countries.

Correct answer: A

Rationale: The correct answer is A: 'The Olympic Games are held every four years,' as stated in the passage. The extract explicitly mentions that the Summer Olympic Games are held every four years. Choice B is incorrect as there is no mention of the Olympic Games being often postponed in the passage. Choice C is incorrect because although the Olympic Games occur during leap years, they are not exclusively held only in leap years. Choice D is incorrect as there is no indication in the passage that the Olympic Games only involve certain countries.

3. What is implied about the rainforest's role in global climate?

A. The rainforest has little impact on the climate.
B. The rainforest plays a crucial role in regulating the climate.
C. The rainforest is mainly important for biodiversity.
D. The rainforest's destruction has no global consequences.

Correct answer: B

Rationale: The rainforest plays a crucial role in regulating the global climate by absorbing carbon dioxide. The extract highlights the fact that trees take in carbon dioxide and give off oxygen. When trees are cut down, the amount of carbon dioxide increases, contributing to global warming. This emphasizes the significant impact of rainforests on the climate. Choice A is incorrect as the extract clearly states the importance of rainforests in absorbing carbon dioxide. Choice C, while true, is not directly related to the implied role of rainforests in regulating the climate. Choice D is also incorrect as the destruction of rainforests does have global consequences, such as contributing to global warming.

4. What is the meaning of the word 'established' as used in the first paragraph?

A. Created
B. Ascertained
C. Founded
D. Reputable

Correct answer: C

Rationale: In this context, 'established' means 'founded' or set up for a long time. The word is used to indicate that phototherapy has been a recognized and in place form of medicine for over a century. 'Created' (choice A) is incorrect as it implies the initial invention of phototherapy, which is not the intended meaning here. 'Ascertained' (choice B) means to find out for certain, which does not match the context of how phototherapy has been practiced. 'Reputable' (choice D) means having a good reputation, which is not the same as being long-standing or founded.

5. 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.
