题目材料：

Agricultural historians theorize that farming originated when the pressures of growing populations or shrinking resources imposed the need to find new species to adapt for food. This hypothesis is supported by impressive work by anthropologists who have observed transitions to agriculture that happened in recent times. But, as an explanation for why agriculture arose in the first place, it seems ill matched to the facts of chronology. Extinctions--or even significant diminutions--in hunters' prey species cannot be shown to have happened in any of the right places at any of the right times. Populations certainly grew in the most dedicated farming cultures--but, in most places, more probably as a consequence than as a cause.

The author of the passage would be most likely to disagree with the "agricultural historians" over whether

Apreagricultural societies frequently adapted new species for food
Bpreagricultural societies were vulnerable to fluctuations in the populations of species they hunted
Cthe earliest transitions to agriculture resulted in population growth
Drecent transitions to agriculture and the earliest such transitions were triggered by similar conditions
Ethe first adoption of agriculture immediately created dramatic changes in social structure
