Query: On the eigenvalues of Grassmann graphs, Bilinear forms graphs and
  Hermitian forms graphs   Recently, Brouwer, Cioab\u{a}, Ihringer and McGinnis obtained some new
results involving the eigenvalues of various graphs coming from association
schemes and posed some conjectures related to the eigenvalues of Grassmann
graphs, bilinear forms graphs and Hermitian forms graphs. In this paper, we
prove some of their conjectures.
