1. As used in the second paragraph, what does the term ubiquitous mean?

A. Indigenous
B. Often ignored
C. Found everywhere
D. Dangerous

Correct answer: C

Rationale: The correct answer is C: 'Found everywhere.' Ubiquitous in this context means widespread presence. In the provided extract, it is mentioned that MRSA bacteria have become ubiquitous not only in hospitals but also in various other settings, indicating they are found everywhere. Choice A, 'Indigenous,' is incorrect as it refers to something native or originating from a specific place, which is not the intended meaning in the context. Choice B, 'Often ignored,' is incorrect as ubiquitous means something that is widely present, not something that is ignored. Choice D, 'Dangerous,' is incorrect as ubiquitous does not directly imply danger, but rather the widespread presence of something.

2. What statement about global warming is made in the passage on the Amazon Rainforest?

A. Global warming is caused by deforestation.
B. Global warming is unrelated to deforestation.
C. Global warming is exaggerated.
D. Global warming is not a concern.

Correct answer: A

Rationale: The correct statement about global warming in the passage on the Amazon Rainforest is that it is caused by deforestation. The passage explains that cutting down trees in the rainforest increases the amount of carbon dioxide in the air, leading to global warming. This is supported by the fact that the burning of Brazilian rainforests alone produces 200 million metric tons of carbon dioxide a year. Choice B is incorrect as the passage clearly establishes a direct link between deforestation and global warming. Choice C is incorrect as the passage does not suggest that global warming is exaggerated, but rather highlights the harmful effects of deforestation. Choice D is incorrect as the passage emphasizes the serious concern of global warming due to deforestation.

3. What is the author’s primary purpose in writing the essay?

A. To persuade the reader to have an ECG
B. To entertain the reader with a heartwarming story
C. To inform the reader how an electrocardiograph reads the electric currents emitted by the heart
D. To analyze the difference between the SA node and the AV node

Correct answer: C

Rationale: The author's primary purpose in writing the essay is to inform the reader about how an electrocardiograph reads the electric currents emitted by the heart. Choice A is incorrect because there is no attempt to persuade the reader to have an ECG. Choice B is incorrect because the essay is focused on providing information rather than entertaining with a heartwarming story. Choice D is incorrect as the essay does not primarily analyze the difference between the SA node and the AV node; instead, it focuses on explaining how an electrocardiograph reads electric currents from the heart.

4. In this passage, which of the following is not mentioned as a role of HGH in the human body?

A. Regulating the metabolism.
B. Stimulating the immune system.
C. Regulating leptin, an appetite-controlling hormone.
D. Facilitating calcium retention.

Correct answer: C

Rationale: The correct answer is C: Regulating leptin, an appetite-controlling hormone. In the provided passage, it is stated that human growth hormone (HGH) is essential for regulating metabolism, building muscle, facilitating calcium retention, and stimulating the immune system. However, leptin is not mentioned as directly regulated by HGH. Instead, the passage discusses how inadequate sleep can lead to lowered levels of leptin, affecting appetite control. Choices A, B, and D are all roles of HGH explicitly mentioned in the passage, making them incorrect answers. Therefore, C is the correct choice as it was not directly linked to HGH in the passage.

5. What is the meaning of the word impoverished in the first paragraph?

A. Honored
B. Nobility
C. Rich
D. financially weakened

Correct answer: D

Rationale: The word 'impoverished' typically refers to a state of extreme poverty or being financially ruined. In the context of the first paragraph, where it is used to describe the condition of a certain group of people, it indicates that they are lacking in financial resources or are in a state of deprivation. Choice A 'Honored' is incorrect as it has a positive connotation opposite to the negative meaning of 'impoverished.' Choice B 'Nobility' is incorrect as it refers to a high social rank or class, which is unrelated to the financial state implied by 'impoverished.' Choice C 'Rich' is incorrect as it is the opposite of 'impoverished,' denoting wealth and abundance, not financial weakness.
