A reading test measures one's ability to read reading tests, and reading tests are in themselves... somewhat akin to the world of crossword puzzles or Scrabble or the game of twenty questions.

But if we ask, What aspect of the world do they comprehend in doing these games well? the answer is, Only the world within the games themselves.
