Query: Abelian quotients of subgroups of the mapping class group and higher
  Prym representations   A well-known conjecture asserts that the mapping class group of a surface
(possibly with punctures/boundary) does not virtually surject onto $\Z$ if the
genus of the surface is large. We prove that if this conjecture holds for some
genus, then it also holds for all larger genera. We also prove that if there is
a counterexample to this conjecture, then there must be a counterexample of a
particularly simple form. We prove these results by relating the conjecture to
a family of linear representations of the mapping class group that we call the
higher Prym representations. They generalize the classical symplectic
representation.
