In the 1960s, surveys of Florida's alligator population indicated that the population was dwindling rapidly. Hunting alligators was banned. By the early 1990s, the alligator population had recovered, and restricted hunting was allowed.

Therefore, in spite of whatever alligator hunting went on, the alligator population must have increased significantly over the decade of the 1990s. Which of the following, if true, most seriously weakens the argument?

【选项】The hunting restrictions applied to commercial as well as private hunters.
