Correct answer: A
Rationale: The most dangerous part of building the Golden Gate Bridge, as mentioned in the passage, was keeping the road balanced to prevent it from collapsing. While constructing the towers and suspending the cables were challenging tasks, the passage specifically highlights the balancing of the bridge as the most treacherous aspect of the construction. Therefore, choice A is the correct answer. Choices B, C, and D are incorrect as they do not reflect the primary danger emphasized in the passage.

Correct answer: D
Rationale: The correct answer is D because the passage specifically states that at the nanoscale, unique properties of materials emerge, which is a key benefit of nanotechnology. Choice A talks about what scientists can do but does not directly describe the benefits mentioned in the passage. Choice B is the definition of nanotechnology and not a specific benefit. Choice C mentions the use of different colors in medical tests, which is a specific application rather than a general benefit of nanotechnology.

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.
