The entanglement experiment described in the textbook demonstrates that
A) any reduction of a particle's position uncertainty is accompanied by an increase in its velocity uncertainty, as predicted by quantum theory. B) a particle's energy is not continuous but is instead quantized in specific, discrete "bundles." C) any attempt to observe which slit a particle goes through, in the electron double-slit experiment, causes the interference pattern to switch to a non-interference pattern. D) two separated particles can exhibit instantaneous non-local connections, as predicted by quantum theory. E) quantum theory's prediction of instantaneous non-local connections between separated particles is incorrect.
