Some philosophers of science claim that no serious scientific theory can be tested experimentally without taking for granted some other body of scientific beliefs, the operation of the instruments-for we cannot interpret the experimental results without appealing to such beliefs. If this is true, then which of the following conclusions seems most likely?
A) Any particular scientific theory can be consistently retained, even in the face of apparently incompatible evidence, if we are willing to give up certain other scientific beliefs.
B) Experimental evidence is really irrelevant to scientific theorizing.
C) Experimental evidence is more relevant to the testing of scientific theories than to their initial formulation.
D) Experimental evidence is more relevant to the initial formulation of scientific theories than to their testing.
E) The best scientific theories are those which are formulated in such a way as to be subject to conclusive experimental refutation.

"for we cannot interpret the experimental results without appealing to such beliefs"

(D) says that experimental evidence is more useful for formulating scientific theories than for testing the theories. And the quoted statement above says that results cannot be interpreted without using previous scientific beliefs. Thus experimental evidence + old theories are used to create new theories, not test old theories.

Is (D) the right answer?

"no serious scientific theory can be tested experimentally without taking for granted some other body of scientific beliefs"

Thus experimental results of other theories are important for testing of new theories..

@S0laris

I think LSAT CRs are very tough as compared with GMAT CRs, but i have seen many high scorers recommending these...not sure whether they would help...
