Situation: I am facing a table while there is a backpack to my left and a chair to my right. There is also a window behind me.
Alternative situations: I am standing in front of the backpack on the floor behind me and examining the table in front of me. I just drop my backpack to the left side as I stand and place both my hands on the rounded edge of the table.
Question: How many chairs can I see on the other side of the table?
