Query: An explicit contextualized hidden variable model replicating an
  indivisible quantum system   Recent experiments and theory have further illuminated the concept of
"quantum contextuality". In this paper we take an inequality - the Pentagram
(or KCBS) inequality, which is violated by an unentangled spin-1 system - and
given a relaxed assumption of non-contextuality show that a hidden variable
model may be constructed that replicates exactly the quantum bound. This is in
contrast to the case of an entangled pair of spin-1/2 particles where a similar
relaxation of the assumption of locality does not lead to a replication of the
quantum bound. Some reasons are proposed for why this may be the case.
