But we are asked about the The Copenhagen interpretation specifically and what we know of that is it "remains the quantum mechanical formalism that is currently most widely accepted amongst physicists".
If the question asked what is true about "quantum mechanics" then E would make more sense.
I understand the the C Interpretation is a derivative of QM, but the only people who care about QM in general are the people mentioned in the passage.
Through POE one could get to E, but even then I don't think its an overly great question or answer.

dcummins - Quantum mechanics (QM) means nothing without Copenhagen interpretation (CI) since CI tells you what QM is. It explains what QM is - probabilistic behaviour of sub atomic particles (not deterministic). You can't separate one from the other. QM is difficult to understand because CI is difficult to understand.
I think we have spent enough time on this question.

Question 1 asks not what einstein thought bout loss of determinism, but what he thought was (correct or incorrect, or anything else.)

q - 3
The local hidden variable theory is discussed in the third paragraph. Consider these sentences: “Albert Einstein, himself one of the founders of quantum theory, disliked this loss of determinism in measurement…(AND) held that there should be a local hidden variable theory (also known as the local realism idea)” From that you can conclude that the local hidden variable theory would have more determinism in measurement, as that was why it was devised. Answer is (D). For (A), the local variable theory only attacked one component of quantum theory not most. For (B), it was later learned to be incorrect based on John Bell’s work. The Einstein-Podolsky-Rosen paradox was used in an attempt to contradict quantum theory and never proved the local hidden variable theory. For (E) it disagreed with those predictions. Answer is (D).
