Situation: I am facing a trash can, while there is a cabinet on my left and an office chair behind me.
Alternative situations: I am throwing out my gum in the trash bin in front of me, the gum was tucked on the backrest of the chair behind me. I am facing the trashcan in front of me and throwing my chewing gun in the trash using my right hand, a chair is behind me.
Question: How many trash cans are on my far left?
