FossilsofthecoralAcrocorapalmatathatdatefromthelastperiodwhenglaciersgrewandconsequen... 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

此题有个很明显的假设,就是认为化石在哪发现,它就一定生活在哪里。
换句话说就是,它死后的化石的位置是不变的。
