题目信息
The retinas of premature babies are not fully developed at birth. Because their retinas are so delicate, premature babies sometimes lose their sight. Methods for preventing this syndrome, which is called retinopathy of prematurity, have improved, but the proportion of premature babies who lose their sight because of this syndrome has increased.
Which of the following, if true, best reconciles the apparent discrepancy described above?
Which of the following, if true, best reconciles the apparent discrepancy described above?
A:When premature babies are born, their retinas are developmentally unprepared to deal with light and air in the environment outside the womb.
B:The oxygen that must be administered to premature babies at birth can sometimes have a damaging effect on the babies' retinas, but the oxygen is now administered in less damaging concentrations than it used to be.
C:The effects of retinopathy of prematurity can be reduced by controlling the exposure of premature babies to light and oxygen, but this method cannot completely prevent the syndrome.
D:The improvement of methods to prevent retinopathy of prematurity has been a gradual process, and there is still a need for further knowledge.
E:Improved medical technology is saving the lives of premature babies who would previously have died, but these babies have even more delicate retinas than do other premature babies and are more apt to lose their sight.

答案E
题目大意：早产儿的视网膜在出生时并未完全发育。由于视网膜如此细腻，早产儿有时会失去视力。预防这种综合征（称为早产儿视网膜病变）的方法已经得到改善，但是由于该综合征而失明的早产婴儿的比例有所增加。
核心逻辑：要区分早产儿、有早产儿视网膜病变的早产儿和因为早产儿视网膜病变而眼睛最终失明的早产儿，来解释为何预防技术提高，但是失明婴儿比例增加。
A.提出无关因素，这不能解释题目中的矛盾。
B.该选项说：出生时必须给早产婴儿使用的氧气有时会对婴儿的视网膜产生破坏作用，但是现在所使用的氧气浓度低于以往。按照这个逻辑婴儿视网膜被破坏的应该减少，该选项仍有矛盾错误。
C.矛盾仍然存在，只是解释了预防的问题。
D.矛盾仍然存在，只说明体术未来仍然有提升空间。
E.先进的医疗技术挽救本该死亡的早产婴儿的生命，但这些婴儿的视网膜比其他早产婴儿的视网膜更加脆弱，更容易失明。这解释了矛盾，技术的提升保护了部分早产儿的生命，但是因为他们本身健康情况较差，所以更容易失明。
