Query: Simple connectedness of Fano log pairs with semi-log canonical
  singularities   We show that any union of slc strata of a Fano log pair with semi-log
canonical singularities is simply connected. In particular, Fano log pairs with
semi-log canonical singularities are simply connected, which confirms a
conjecture of the first author.
