Based on the information in the passage, with which one of the following statements regarding solar electrical system...

Renewable sources of energy

Whyyy A??? Is it that if they lol at long term and use local involvement in all levels, they too can succeed and profit ?? Why not C? Is it because we only know rural we cannot assume about dense and not rural?? Thank you!! :)

(A) is the correct answer because of the wording the author uses. In line 44 the author states, "Thus, the movement toward a sustainable, rural electricity system in Brazil remains stalled." The author doesn't say rural electrical systems are not implementable. She merely states that rural electricity systems in Brazil remain stalled. Furthermore, the use of the word "stalled," is important. Something that is stalled, is merely hampered, delayed or interrupted, as opposed to being completely thwarted or halted. More over, line 46 sheds more light on the author's opinion, "But some efforts have avoided these pitfalls." Therefore, there are some places that can use electrical systems, such as in India. Though it is true that the system that worked in India was wind energy as opposed to solar energy, the tone of the author sets forth that though there are difficulties, some countries can profitably implement solar electrical systems.

(C) is incorrect because we never discuss the characteristics of densely populated areas as opposed to rural areas. Thus, we do not know the author's opinion on where the systems would be more effectively employed.

Hi, Naz... The issue I have with A is that I can not see how one successful implementation in India translate in successful implementations in many countries. I could have assumed that, but using the information in the passage, it not apparent.

Answer choice (A) states: "Despite previous difficulties, these systems CAN be implemented profitably in many countries."

The answer choice states that the systems COULD work in many countries. It does not say that they WILL work. Through the example set forth in the last paragraph, the author explains that because the Danish agency "recognized the importance of local involvement at all levels," the project was successful (59-60). Thus, the author is explaining that it is POSSIBLE for this kind of system to work; therefore, it COULD work in other places.

We use the tone of the passage, which is a hopeful tone for these systems as long as they are implemented correctly, to infer that the author would agree that these systems CAN work in other countries.

Hope that clears things up! Please let us know if you have any other questions.
