Can someone in a wheelchair see clearly?
A lecture hall is full of people listening to a speaker at a podium at the front of the room. The audience is listening intently. An astonished woman in a wheelchair is seated behind a pillar at the back of the hall and is trying to peer out from behind the pillar to get a glimpse of the speaker. The speaker is oblivious to the fact that the person in the wheelchair is unable to see her.
