红学索隐派是指研究《红楼梦》的一个派别，又称政治索隐派。所谓索隐即透过字面探索作者隐匿在书中的真人真事。索隐派的主要手段是大作繁琐的考证，从小说的情节和人物中考索出“所隐之事，所隐之人”。
定义，下列各项属于索隐派的是( )。

A．脂砚斋是《石头记》最早的评论家，他曾写下如“书中人目太繁，故注明一笔，使观者省眼”(解释“此即冷子兴所云之史氏太君，贾赦贾政之母也”一句)等诸多评语
B．蔡元培认为，《石头记》者，清康熙朝政小说也。作者持民族主义甚挚，书中本事在吊明之亡揭清之失，而尤于汉族名士仕清者寓痛惜之意
C．唤明在其《金陵十二钗咏》中，给宝黛钗指明了一条“出路”：冷香错拟似环肥．梦主荒唐惹是非。不为檀郎留佩玉，只怜贫女失罗衣。残春恨在莺儿老，暮雨愁深燕子飞。若向红楼觅佳偶，薛君才合配湘妃
D．国学大师王国维最早从哲学与美学的观点来批评《红楼梦》之艺术价值

The idea of test-tube babies may make you either delighted at the wonders of modern medicine or irritated while considering the moral, or legal, or technological implications of starting life in a laboratory. But if you’’ve ever been pregnant yourself, one thing is certain: You wonder what it’’s like to carry a test-tube baby. Are these pregnancies normal Are the babies normal The earliest answers come from Australia, where a group of medical experts at the Queen Victoria Medical Center in Melbourne have taken a look at the continent’’s first nine successful invitro pregnancies. The Australians report that the pregnancies themselves seemed to have proceeded according to plan, but at birth some unusual trends did show up. Seven of the nine babies turned out to be girls. Six of the nine were delivered by Caesarean section. And one baby, a twin, was born with a serious heart defect and a few days later developed life-threatening problems.What does it all mean Even the doctors don’’t know for sure, because the numbers are so small. The proportion of girls to boys is high, but until there are many more test-tube babies no one will know whether that’’s something that just happened to be like that or something special that happens when egg meets sperm in a test tube instead of a fallopian tube. The same thing is true of the single heart defect. It usually shows up in only 15 out of 60,000 births in that part of Australia, but the fact that it occurred in one out of nine test-tube babies does not necessarily mean that they are at special risk. One thing the doctors can explain is the high number of Caesareans. Most of the mothers were older, had long histories of fertility problems and in some cases had had surgery on the fallopian tubes, all of which made them likely candidates for Caesareans anyway.The Australian researchers report that they are quite encouraged. All the babies are now making normal progress, even the twin with the birth defects.

Which of the following statements about the experiment mentioned in the passage is true

A．Only the twins are defected.

B．Most of the babies are delivered by means of Caesarean.

C．There are some troubles during all mothers’ pregnancies.

D．One baby appears to be abnormal.
