Kidneys<br>My friend Cam's back started hurting him. He went to urgent care. They said his kidneys were not functioning well. He went to his pcp, a urologist, and a nephrologist. They are still running tests.
Cam knew where his kidneys were
Cam knew he had pain, but there was no context for his knowledge of anatomy and therefore no indicator that he knew where his kidneys were. This was difficult for the system because the computer has no context for Cam's background knowledge
