   Suppose, on the other hand, that, for each ground model M, we can isolate a privileged acceptable interpretation as the correct interpretation of T. Gupta and Belnap present a number of considerations against the three-valued semantics, so conceived. (See Gupta &amp; Belnap 1993, Chapter 3.) One principal argument is that the central theorem, i.e., that for each ground model there is an acceptable interpretation, only holds when the underlying language is expressively impoverished in certain ways: for example, the three-valued approach fails if the language has a connective ~ with the following truth table:
