Situation: I am facing a table with two lamps over it and there is a backpack behind me.
Alternative situations: I am trying to reach the lamp in front of me on my left side to turn on on the table but the table is on the way in front of me. I am standing at the head of the table on the left side of the room and frustratedly squinting to read the words on the whiteboard in front of me because it is too small.
Question: How many tables are in the room?
