Situation: I am sitting on the office chair studying.
Alternative situations: I am reading a letter while sitting on the office chair in front of the desk. I am about to write a postcard for my friend, sitting at a desk and reaching for a lamp in my eleven o'clock direction. There are some drafts I did earlier in a trash can in my five o'clock direction.
Question: What color is the carpet that I am sitting on top of in a chair?
