Studies have established that children who watched 2 more hours of TV on an average daily basis during the first 15 years of their life were 50℅ more likely to be arrested for property crimes in the country.
Researchers believe that these studies clearly establish that violence in movies and TV contribute to aggressive behavior in real life. On the other hand, there is no clear evidence that the programs that the kids watched on TV were violent in the first place. Even if we were to accept that TV watching contributed to the increased crime rate, it need not have been because of the nature of the programs.
Perhaps, children who watched programs such as Adams and Samson, a funny sit-com about two blundering cops began perceiving all cops as incompetent.What is the role of the sentences in boldface?
[A]The first establishes a theory that the author later clearly refutes while the second presents the author's conclusion
[B]The first is an interpretation made by researchers that the author contends against and the second provides an alternative explanation for statistical data
[C]The first is an opinion expressed by someone other than the author and which the author is completely in disagreement with while the second provides the reason for the author's doubt.
[D] The first is a fact supporting the researcher's conclusion while the second is the author's conclusion.
[E]The first is a clearly proven opinion even if the author disagrees with it while the second is an ambiguous opinion that has no supporting data.
The first bold face is the researchers conclusion/interpretation. The author does not blatantly says that researchers conclusion is wrong. He shows other possibilities or interpretations from the same set of data. Thus option B is correct.
