Q29: PP-10

The yield per acre of coffee berries varies enormously in that a single tree, depending on both its size and on climate and altitude, could produce enough berries to make between one and twelve pounds of dried beans a year.




A. enormously in that a single tree, depending on both its size and on climate and altitude, could produce

B. enormously in that a single tree, dependent on its size and also on climate and altitude, is able to produce

C. enormously, because a single tree, depending on its size and on climate and altitude, is able to produce

D. enormously, because a single tree, being dependent on its size, climate, and altitude, is capable of producingE. enormously, because a single tree, dependent both on its size as well as on climate and altitude, could produce

答案是C，疑惑项是B。
B的and also不能算是错误标志吧？错在哪了呢？
想问一问Ｃ中关于并列的表达：depending on its size and on climate and altitude
这样复杂的表达是标准的么？还有没其他正确的表达呢？

The yield per acre of coffee berries varies enormously, because a single tree, depending on its size and on climate and altitude, is able to produce enough berries to make between one and twelve pounds of dried beans a year.
这个句子里depending不能改为dependent，因为depending和dependent的区别在于，前者伴随修饰谓语动词is able to produce，后者则是修饰名词single tree，会造成逻辑上不对 —— “一棵树依靠它的size”。
