1. What is the meaning of the word 'ideal' as it is used in the first paragraph?

• A. thoughtful
• B. confined
• C. hostile
• D. perfect

Correct answer: D

Rationale: In this context, 'ideal' means perfect. The human body provides a perfect environment for many microbes, as stated in the extract. It is the immune system's role to keep these microbes out or destroy them. The other choices are incorrect: 'thoughtful' does not fit the context of the sentence, 'confined' and 'hostile' are not synonymous with 'ideal' in this context.

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. 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.

4. Why was the roadway of the Golden Gate Bridge so dangerous to build?

• A. It was located above a fast-moving river.
• B. It had to be perfectly balanced to avoid collapse.
• C. The materials used were very unstable.
• D. It was built during bad weather.

Correct answer: B

Rationale: The correct answer is B. The passage describes how the road had to be balanced during construction to avoid collapse into the bay. Choice A is incorrect as the Golden Gate Bridge crosses a strait, not a river. Choice C is incorrect as there is no mention of unstable materials. Choice D is incorrect as bad weather is not highlighted as a specific reason for the danger in building the roadway.

5. In context, the word 'defective' in the first sentence of the passage means which of the following?

• A. Unusual
• B. Remarkable
• C. Postponed
• D. Faulty

Correct answer: D

Rationale: In the context provided, 'defective' means faulty, referring to the gene that causes cystic fibrosis (CF). The passage explains that CF is caused by a defective gene, resulting in the production of abnormally thick and sticky fluid. The word 'defective' suggests that the gene is not functioning correctly, leading to the symptoms associated with the disease. Therefore, 'faulty' is the correct choice. The other options, 'unusual,' 'remarkable,' and 'postponed,' do not accurately capture the meaning of 'defective' in this context and are therefore incorrect.
