Explanation:

Question 18 (Assuming the first question is about wind turbine benefits or issues, but the exact question is unclear from the image. Let's assume it's about a positive effect of wind turbines. Option B says "One good effect from wind turbines is that they do not create air or ground pollution the way conventional or nuclear power plants do." So if the question is about a benefit, B is correct. But since the exact question is partially visible, let's proceed with the visible parts.)

Question 19: Which sentence shows the author’s perspective that wind power is a great choice?

To determine this, we analyze each option:

• Option A: "Wind power is one of the sustainable power sources we use." (Paragraph 1) directly states wind power is a sustainable (and thus great) power source.
• Option B: Talks about farmland value, not the author's view on wind power as a great choice.
• Option C: Discusses cost to taxpayers, not a positive view of wind power as a choice.
• Option D: Mentions a negative (disturbing night views), not a positive view of wind power as a choice.

So Option A is correct.

The main idea of an article about wind energy likely addresses its overall worth considering challenges.

• Option A: Introduces wind power as sustainable, but not the main idea (which might involve challenges).
• Option B: Presents data on property values, a detail.
• Option C: Mentions a negative (disturbing views), a detail.
• Option D: "Until we meet [the challenges], wind energy may not be worth it." (paragraph 8) suggests wind energy has challenges to overcome to be worthwhile, which is a main idea - weighing wind energy's value against its challenges.

So Option D is correct.

Answer:

A. "Wind power is one of the sustainable power sources we use." (paragraph 1)
