问题 The first animals on this living sphere, the Earth, were primitive______animals, and then around 500 million years ago these sea animals developed shells.

选项 A、versatile
B、marine
C、redatory
D、feasible

答案 B

解析句子大意为：地球上的首批动物是原始海洋动物，然后在大约500万年前这些海洋动物进化出了身上的壳儿状物。句子后半句提到“这些海洋动物”，可知空中应该也是同样意思，四个选项中只有选项B是“海洋的”之意。
