and in the absence of evidence establishing the contrary a person shall be taken for the purposes of this section to decide upon an omission when he does an act inconsistent with doing the omitted act or, if he has done no such inconsistent act, when the period expires within which he might reasonably have been expected to do the omitted act if it was to be done.
