I read the following sentence:
Indeed, it was precisely because of its futuristic storyline that Star Trek was able to address many of the contemporary social problems that other programs shunned.
I am aware of the emphatic structure, "it is .... that..." and I think this structure "it was because of ... that" sort of resemble the "emphatic structure." Nevertheless, I still figure there are differences.
Could anyone explain why it is constructed this way?
