thnx for all explanation , firstly.
as far as what i have understood from you , it means it is expected to do so.
but today i get confused with sth again that likes this.this is the sentence
"if we are to look behind the mere facts of behaviour for an explanation of this phonemenon."
why it is not in such a way " if we look behind the mere.. ......."
or " if we are going to look.."
or sth else. i cant find a common point with "was to do sth"
has it a relevance with expectations?
