问题 The most versatile______embryonic stem cells, which______found in the embryo at the earliest stage of development and grow into any part of the body.
选项 A、is: is
B、are: are
C、are: is
D、is: are
答案 B
解析 句意：最全能的是胚胎干细胞，胚胎干细胞在胚胎发育的早期就能被发现，并长成身体的任何部分。主语embryonic stem cells是复数，形容词versatile和定语从句均修饰主语，故两个空都填复数形式are。
