[...] it is possible to have descriptions exemplifying each of four combinations of "definitiveness" of the adjective and appropriateness of the article. In conditions 1 and 3, the adjective effectively partitions the environment, and is thus "definitive". The article is appropriate in conditions 2 and 3, and anomalous in condition 1 and particularly in condition 4.
