Q10 - Double-blind techniques should be

[dan]

10. (B)
Question Type: Analyze Argument Structure
This argument starts with the main conclusion, and answer (B) does the best job of expressing this conclusion (in slightly different words). Everything else in the passage is used to support this main conclusion.

(A) is attractive because it’s true according to the text. However, (A) restates a supporting premise of the argument, not the main conclusion of the argument. The fact that they are biased in their interpretations is reason to use double-blind techniques.
(C) may be reasonable as a conclusion that a normal person might draw, but it is not the conclusion stated in the passage.
(D) is attractive because it restates part of the text. Furthermore, this feels like a claim (conclusion), but is it the final conclusion? No. It is an intermediate conclusion that supports the final conclusion: Scientists should avoid misinterpretations, THEREFORE they should use double-blind experiments whenever possible.
(E) may be implied by the passage, but it is not the conclusion. The conclusion is that they should be used when possible.
