UPSC 2013 CDS 2 GK Paper

Silent Spring is an environmental science book by Rachel Carson. The book was published on 27th September 1962 and it documented the adverse effects on the environment of the indiscriminate use of pesticides. So, the most appropriate answer would be fourth option because specifically the adverse effect of pesticide on environment is not mentioned. In the absence of fourth option, second option would have been the closest.
