Choose the correct letter, A, B, C or D.
Write the correct letter in boxes 22-26 on your answer sheet. [br] The decrease in the number of whales and seabirds is due to
选项
A、killer whales’ activity around Antarctica.
B、the correlation between sea birds’ migration and the salinity level of the ocean.
C、the lower productivity of food source resulting from less sea ice.
D、the failure of seals to produce babies.
答案
C
解析
根据关键词“whales and seabirds”定位到原文E段最后两句话“Antarctic krill…breed well in years when sea ice is extensive and poerly when it is not”,南极洲的磷虾在海冰丰富的时候繁殖良好,反之不然。而磷虾是“whales and seabirds”的主要食物,因此符合冰少磷虾就少(这里的“Antarctic krill”等同于“food source”),磷虾少就是等同食物变少,食物变少“whales and seabirds”的数量也就下降了,所以正确答案是C。
