1. 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.

2. Which part of the bridge was built first according to the passage on Golden Gate Bridge?

A. The cables.
B. The anchorages.
C. The roadway.
D. The towers.

Correct answer: B

Rationale: The correct answer is B, 'The anchorages.' The passage states that construction began by building the anchorages first. After that, the builders moved on to the towers, then the cables, and lastly, the roadway. Building the anchorages was crucial to providing a stable foundation for the bridge. Choices A, C, and D are incorrect because the passage clearly outlines the sequence of construction starting with the anchorages.

3. 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.

4. What conclusion can be drawn from the passage on bicycles?

A. Bicycles have been evolving for centuries.
B. Bicycles have evolved significantly over time.
C. Bicycles have remained unchanged since their invention.
D. Bicycles are no longer a popular means of transportation.

Correct answer: B

Rationale: The correct conclusion that can be drawn from the passage is that bicycles have evolved significantly over time. The passage discusses the evolution of bicycles from their early wooden, pedal-less designs to the modern safety bicycle with equal-sized wheels and chain-driven pedals. Each inventor mentioned in the passage contributed to significant improvements in bicycle design, making them more efficient and popular for transportation and recreation. Choice A is incorrect because the passage does not mention bicycles evolving continuously for centuries, but rather highlights specific innovations over time. Choice C is incorrect as the passage clearly describes the various improvements and changes made to bicycles since their invention. Choice D is also incorrect as the passage emphasizes the continued popularity and usefulness of bicycles for transportation all over the world.
