问题     Once they decided to have children, MiShel and Carl Meissner tackled the next big issue: Should they try to have a girl? It was no small matter. MiShel’s brother had become blind from a hereditary (遗传的) condition in his early 20s, and the Meissners had learned that the condition is a【C1】______ passed from mothers to sons. If they had a boy, he would have a 50 per cent chance of having the condition. A girl would be【C2】______.

    The clinic offers sex selection for two purposes: to help couples【C7】______ passing on a gender-linked【C8】______ disease and to allow those who already have a child to "balance" their family by having a baby of the opposite sex.
    The technology is still【C9】______ However, Blauer says the company has an【C10】______ success rate: 91 per cent of the women who become pregnant after sorting for a girl are successful, while 76 per cent who sort for a boy and get pregnant are successful.
A) genetic B) overlapped C) impressive D) unaffected
E) perpetually F) investigation G) inquiries H) feats
I) disorder J) gropes K) experimental L) seemingly
M) elicit N) nonmedical O) avoid [br] 【C8】
选项
答案 A
解析 此处应填入修饰disease的词，可为名词、形容词或动词分词。从本文首段提到的个案和本句提到的gender-linked可以推断空格处的单词应表明“遗传性”疾病，因此genetic为本题答案。
