53. The "immunotolerance" of a pregnant woman toward her unborn child
is the result of
(A) the complete physical separation from her cells and those of
the unborn child.
(B) the tenacity with which the unborn child's immune system
counteracts the woman's immune system.
(C) the unborn child having enough of the woman's identity so as
to escape detection as foreign.
(D) modern medical intervention during every pregnancy.
(E) the relative quiescence of a pregnant woman's immune system
compared to when she was not pregnant.
答案E
B、C、D我都知道是錯的，我想問有E這種情形嗎？ 母親免疫力會下降嗎？
因為我不知道有E的情形我選A，但是A不是也算對嗎？
母親與胎兒的"細胞"應該有完全隔離吧！
