OK. Here we have three blank 'envelopes' ... a common everyday 'object' has been placed in one of the objects. Your task is the same .... identify which envelope the object has been placed in, and what is the object?
There is a third part to this exercise ... a much harder task even ... the object in the envelope was not my original choice of object for this object ... some other object has been chosen and, at the last moment, not used for this exercise. I am projecting this awareness of this object into this post ... can you get a sense of what this unused object is (Its awareness can be an abstract statement to describe it) ... Good Luck as this task is not easy.
