    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] 【C1】
选项
答案 I
解析 此处应为单数名词。根据该句中的blind一词可以知道句中提到的condition其实是一种“疾病”或“不正常的情况”。disorder为本题答案。
