Geographers and historians have traditionally held the view that Antarctica was first sighted around 1820,but some sixteenth-century European maps show a body that resembles the polar landmass,even though explorers of the period never saw it.Some scholars,therefore,argue that the continent must have been discovered and mapped by the ancients,whose maps are known to have served as models for the European cartographers.
which of the following if ture,is most damaging to the inference drawn by the scholars?

A the question of who first sighted America in modern times is still muh debated,and no one has been able to present conclusive evidence.

B.between3000and9000years ago,the world was warmer than it is now,and the polar landmass was presumable smaller.

c.there are only a few sixteen-century global maps that show a continental landmass at the South pole.

d.mose attribution of surprising accomplishments to ancient civilization or even extraterrestrials are eventually discredited or rejected as preposterous.

e.ancient philosophers believed that there had to be a large landmass at the South Pole to balance the northern continents and make the world symmetrical.

正确答案是e。为什么丫？

本题争论的焦点是“有没有证据显示这块大陆在18世纪以前已被人发现”。一些学者提出的观点是基于“有这样的证据”而对传统观点提出质疑的。若这个证据存在漏洞，则结论不成立。

e.ancient philosophers believed that there had to be a large landmass at the South Pole to balance the northern continents and make the world symmetrical.

古代的哲学家由于考虑到对称性才“认为”地图上应该有这么一块大陆，并不是实地考察得出的。

LS is right. E provides another reason why there is a land mass at the South pole other than some earlier human has found it.
