So for couple of particles to be entangled one requires assessment of three properties (A, B, C), unless of course there is some other definition of finding out correlation and establishing violation of inequality. Cat is dead, the other oft given example is that two photons are produced now due to conservation of angular momentum if one has clockwise angular momentum at the time of measurement then the other photon will be found with anti clockwise angular momentum when measured. So far no big deal both QMly and classically! Now as I could figure out.....once the first photon angular momentum is measured, the second photon angular momentum is determined, but the second photon is in a state of superposition (QMly) before measurement, that means it could have any direction angular momentum (of course axis being same) if only local effects are to be considered, but on measurement it is found counter to its remote entangled partner whose measurement was earlier done. Surely the correlation for this direction is higher thus violating Bell's inequality.
