Situation: I am sitting on a chair facing another chair with a jacket on it while there is a backpack on the table by my right.
Alternative situations: I am sitting on a brown chair on the left side of the room with both my feet resting on the black office chair in front of me. I am sitting in a chair with a table to my right and a backpack on it next to me.
Question: How many backpacks are behind me to the right?
