1. What is the meaning of the word 'shifts' as used in the third paragraph?

A. Alterations
B. Stints
C. Removals
D. Transfers

Correct answer: A

Rationale: In this context, 'shifts' refers to changes or alterations in brain chemistry and electrophysiology. The word 'alterations' best captures the idea that significant changes are occurring in the brain. 'Stints' (choice B) refer to short periods of time or work, which is not the meaning intended here. 'Removals' (choice C) and 'transfers' (choice D) do not fit the context of the sentence and are not related to the changes happening in the brain as described in the extract.

2. Which conclusion can the reader draw after reading this passage?

A. The climate crisis has increased deaths from heatstroke.
B. Heat exhaustion rarely occurs in dry environments.
C. The cessation of sweat is not necessarily a positive sign.
D. Temperatures below 90 degrees are usually not dangerous.

Correct answer: C

Rationale: The passage notes that stopping sweating entirely is a serious sign that requires medical attention.

3. Where is Thailand located?

A. Africa
B. Europe
C. South America
D. Asia

Correct answer: D

Rationale: Thailand is located in Asia, not South America. Thailand is a country in Southeast Asia known for its beautiful beaches, rich culture, and delicious cuisine. It shares borders with Myanmar, Laos, Cambodia, and Malaysia. The extract provided also mentions the country of Siam, which is now known as Thailand, indicating its location in Asia. Choices A, B, and C are incorrect as Thailand is not located in Africa, Europe, or South America.

4. What is the meaning of the word 'evolved' in the first paragraph?

A. To spread
B. To gradually develop
C. To revolve
D. To shift

Correct answer: B

Rationale: In the context of the given extract, 'evolved' means to gradually develop. The systems in the body have evolved over time, indicating a gradual development and adaptation. 'To spread,' 'to revolve,' and 'to shift' do not capture the idea of a gradual development as portrayed in the text, making them incorrect choices.

5. What is the main idea of the passage about MRSA?

A. Methicillin-resistant Staphylococcus aureus (MRSA) is a significant problem both within and outside of hospitals, and there are ways to mitigate the risk.
B. A new textile made of nanomaterials could significantly reduce the spread of hospital-associated MRSA infections.
C. There are multiple strains of MRSA, and they pose various risks beyond just fatality.
D. MRSA is a significant problem both within and outside of hospitals, but there are ways to mitigate the risk.

Correct answer: D

Rationale: The main idea of the passage is that MRSA is a significant issue both within and outside of hospitals. It highlights the challenges posed by MRSA, including its resistance to antibiotics, high mortality rates, and widespread presence in various settings. While the development of new technologies like nanomaterial textiles shows promise in reducing hospital-associated MRSA, the passage also emphasizes the importance of practicing good hygiene to prevent community-associated MRSA infections. Choices A, B, and C are incorrect because they do not capture the comprehensive overview of MRSA provided in the passage. Choice A encompasses the main idea by emphasizing the significance of MRSA and ways to mitigate the risk. Choice B focuses on a specific solution rather than the broader issue of MRSA. Choice C is incorrect as it oversimplifies the risks associated with MRSA strains by only mentioning fatality.
