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我都知道是错的，我想问有E这种情形吗？ 母亲免疫力会下降吗？
因为我不知道有E的情形我选A，但是A不是也算对吗？
母亲与胎儿的"细胞"应该有完全隔离吧！
