Paragraph 3 supports the idea that one problem with the broken-forest hypothesis is that A. ecologists have found gliding animals in areas of Southeast Asia where trees are connected by vines and not found them in Amazonian forests where trees are not connected by vines B. in Southeast Asia, the forests with the fewest woody vines connecting the tops of trees turn out to have the most gliding animals C. according to ecologists in different regions of the world, gliding animals are as abundant and varied in some forests of Africa and the New World as they are in Southeast Asian forests D. gliding is no easier in broken forests with an uneven canopy structure than it is in forests where the trees are all about the same height
