24. The author regards the idea that traditional quantum mechanics is incomplete with
(A) approval
(B) surprise
(C) indifference
(D) apprehension
(E) skepticism
25. It can be inferred from the passage that the author's conclusion that Einstein's approach is "
erroneous" might have to be modified because
(A) it is theoretically possible to generate plausible theories with hidden parameters within them
(B) some experimental tests of Einstein's theory do not disconfirm the hidden-parameter theory of quantum mechanics
(C) it is possible for a theory to have hidden parameters and yet be probabilistic
(D) traditional quantum mechanics has not yet been used to analyze all of the phenomena to which it could be applied
(E) there are too many possible hidden parameters to develop meaningful tests of hidden parameter theories
26. According to the passage, Einstein posed objections to the
(A) existence of hidden parameters in quantum theory
(B) probabilistic nature of quantum mechanics
(C) idea that quantum mechanics is incomplete
(D) results of experiments testing quantum theory
(E) the importance accorded quantum mechanics in physics
27. The passage suggests that which of the following would have resulted if the experiments mentioned had
not supported the predictions of traditional quantum mechanics?
(A) Einstein, had he been alive, would have revised his approach to quantum mechanics.
(B) Hidden-parameter theories would have been considered inaccurate descriptions of real-world phenomena.
(C) A deterministic description of the motion of a particle might still be considered possible.
(D) Quantum mechanics would have ceased to attract the attention of physicists.
(E) Einstein, had he been alive, would have abandoned attempts to specify the hidden parameters that describe motion.
