托福听力official32 The phrase “the latter adaptation” in the passage refers to 答案解析

原文出处：Alternative strategies have evolved in some plants, such as those that produce fewer but larger seeds that are dispersed to suitable sites by birds or small mammals or those that produce long-lived seeds. Many forest plants seem to exhibit the latter adaptation and viable seeds of pioneer species can be found in large numbers on some forest floors. the latter adaptation,指代的是前面提到的两种适应方法的后一种，所以我们需要往前找答案。前一句话提到2种适应性：第一种是生产少一点，但是个头更大的种子，可以被鸟类或其他小的哺乳动物传播到合适的地方；第二种就是生产long-lived seeds, 所以后一种适应性是指长命种子。所以D选项正确。
