Based on the passage, we can infer that the author would be most supportive of which one of the following practices?
Explanation:
The question asks us to pick a choice that the author would be most supportive of. 1 goes out because the author in the last paragraph says that localised renewable energy systems is unlikely to generate high returns for investors. 2 can be definitely inferred because the author clearly says at the end of second last para that disposal of toxic waste has perpetuated social injustice. Thus 2 is the right choice. For many 3 might be a tempting choice, but it is beside the point. The author is not concerned with more environment friendly carbon based fuels. He is talking about renewable energy sources, and the social and financial costs behind it. The whole discussion in the passage is based on the premise that we have already taken the path low carbon based renewable energy path. So the suggestion in 3 is pointless. 4 goes out because the author is not favouring any study. He wants resolution to the problem, so he wants action.
Hence, option (b) is correct.
