Expression of Ideas practice question

While researching a topic, a student has taken the following notes: - A proposed tidal energy scheme would supply 8 percent of the region's electricity. - It would close off a bay used by 20,000 wading birds, which could not be relocated. - Offshore wind turbines could supply 6 percent of the region's electricity at 1.4 times the tidal scheme's cost per unit. - The wind option would not affect the bay. The student wants to argue against the tidal scheme while acknowledging its main advantage.

Which choice most effectively uses relevant information from the notes to accomplish this goal?

  1. A. Although the tidal scheme would supply 8 percent of the region's electricity, it would destroy a bay that 20,000 wading birds depend on and cannot leave, whereas offshore wind could supply nearly as much power without that loss.Correct
  2. B. The tidal scheme would supply 8 percent of the region's electricity.
  3. C. Offshore wind costs 1.4 times as much per unit as the tidal scheme.
  4. D. The tidal scheme should not be built.

Answer: A. Although the tidal scheme would supply 8 percent of the region's electricity, it would destroy a bay that 20,000 wading birds depend on and cannot leave, whereas offshore wind could supply nearly as much power without that loss.

Advantage granted, cost stated, alternative offered.

Why the other answers are wrong

B. The tidal scheme would supply 8 percent of the region's electricity.
The advantage alone, arguing for the scheme.
C. Offshore wind costs 1.4 times as much per unit as the tidal scheme.
A point against the alternative.
D. The tidal scheme should not be built.
No acknowledgement, no reason.
