What point does the professor make when she discusses the maclura tree?A. The feeding habits of large animals could help revive some diminishing plant species.B. The climate has changed in North America since the Pleistocene epoch.C. Mass extinctions of animals are generally preceded by mass extinctions of plants.D. The maclura tree has changed very little since the Ice Age.

Answer 1

Professor: Another example is the interaction of megafauna with local flora, in particular, plants that rely on animals to disperse their seeds. Like Pleistocene rewilding could spark the re-emergence of large seeded American plants, such as the maclura tree.教授说一些大型动物和本土植物会相互作用，有些植物会依靠动物去传播自己的种子。然后举 maclura tree 的例子。所以教授提到 maclura tree 是为了说明有些植物会依靠动物去传播自己的种子。所以 A 选项正确。
