Query: On the Busemann-Petty problem concerning central sections of centrally
  symmetric convex bodies   We present a method which shows that in $\Eb$ the Busemann-Petty problem,
concerning central sections of centrally symmetric convex bodies, has a
positive answer. Together with other results, this settles the problem in each
dimension.
