Query: On the relation between 2 and infty in Galois cohomology of number
  fields   We remove the assumption "let p be odd or k totally imaginary" from several
well-known theorems in Galois cohomology of number fields. For example, we show
that the Galois group of the maximal extension of a number field k which is
unramified outside 2 has a finite cohomological 2-dimension (also if k has real
places).
