Query: Section and towers   We discuss the towers of finite \'etale covers which were essentially
introduced by A.Tamagawa. The statement about correspondence between sections
and cofinal towers is a folklore but perhaps not in a very explicit form. The
last section explains how the "injectivity statement" of Grothendieck section
conjecture fails for abelian varieties, which is also known in some form.
  The paper is based on an earlier article which was aimed to reinterpret
anabelian setting in model theory terms.
