Give an example where the read one, write all available approach leads to an

erroneous state.

In the majority protocol, what should the reader do if it finds different values

from different copies, to (a) decide what is the correct value, and (b) to bring

the copies back to consistency? If the reader does not bother to bring the

copies back to consistency, would it affect correctness of the protocol?
