Contrary to anthropologists' predictions, the size of remaining hunter-gatherer societies has not decreased in recent decades. Yet even though deforestation and the disappearance of traditional food sources have continued, the size of hunter-gatherer societies over the last ten years has increased by more than 5 percent over the previous ten years' levels.
Any of the following statements, if true about the last ten years, helps to explain the increase in the size of hunter-gatherer societies EXCEPT:
(A) The anthropologists' predictions are now known to have ignored several environmental factors that affect the survival of these societies.
(B) Many traditionally violent hunter-gatherer societies have been unusually peaceful, losing few men in battle with other tribes.
(C) State financial support, designed to allow hunter-gatherer societies to survive in their present form, increased by 20 percent.
(D) Wildlife conservation programs around the world have made it easier for these societies to successfully hunt big game.
(E) Droughts, which typically strike many of the regions where hunter-gatherer societies live every three to five years, have been mild.
