I thought the whole point of argument here is ensuring objectivity mainly due to the fact that the issue of misrepresentation and expectations and opinions scientists already hold all all bout objectivity. This creaky makes answer choice E more dare levant and correct than B

Hi, Bereket -
This question is tricky because the "conclusion" of the argument is actually its first statement: "Double-blind techniques should be used whenever possible in scientific experiments." The remainder of the paragraph consists of the supporting argument. The correct answer is therefore the one that is most nearly a restatement of this conclusion, i.e., [B].
[E] is tempting, but although the argument recommends double-blind techniques to "help prevent" misinterpretations caused by lack of objectivity, it does not claim that these techniques ENSURE objectivity. That statement is too strong. Moreover, the argument's actual conclusion is that double-blind techniques should be used wherever possible; this answer does not express that. (The reader may infer that the techniques should be used, but that is not the same thing.)
