CXD逻辑，从来没见过的一种意思表达

38.Fossils of the coral Acrocora palmata that date from the last period when glaciers grew and consequently spread from the polar regions are found at ocean depths far greater than those at which A. palmata can now survive. Therefore, although the fossilized
A. palmata appears indistinguishable from A. palmata now living, it must have differed in important respects to have been able to live in deep water.The argument depends on the assumption that
(A) no fossils of the coral A. palmata have been  found that date from periods when glaciers were not spreading from the polar regions
(B) geological disturbances since the last period during which glaciers spread have caused no major downward shift in the location of A. palmata fossils
(C) A. palmata now live in shallow waters in most of the same geographical regions as those in which deep-lying A. palmata fossils have been found
(D) A. palmata fossils have been found that date from each of the periods during which glaciers are known to have spread from the polar region
(E) A. palmata can live at greater depths where the ocean temperature is colder than they can where the ocean temperature is warmer
其中A.算什么？怎么会和Acrocora有关

难道这道题选择A？楼主能给个答案么？

girlwithwings

A吗？搞不懂也。
A：在冰河。。。之前没发现（文中：在之后有） 有什么关系呢？？？

我选B。 排除他因
意思就是没有任何的地壳板块移动（他因）造成A.Pdownward到海洋深处，而是它原来就长在那里。

我的本意是：
A. 为什么＝Acrocora

你不给出答案，让别人来猜啊，谁还能给你解释。
我感觉是A，没有答案，不解释

prayer

不对，重新看了，应该是B，算了，等楼主的答案吧

答案是ｂ，知道答案真的那么重要吗？

是啊，你有疑惑的题目，也是别人学习的一次机会，别人看完了，选了答案，不知道对错，你觉得花这个时间来看一道没有答案的题目有意义么？

A.表示缩写。

No. 这个很熟悉吧
