As for the alleged value of expert opinion , one need only consult government records to see strong evidence of the ___ of such opinions in many fields.
A complexity
B failure
C uniqueness
D success
E excitement
選B
翻譯：至于專家意見的所謂的價值，任何人只要翻翻政府記錄就會發(fā)現(xiàn)，它們在很多領域都相當不靠譜。
only引導的條件關系。
as for 關于，至于，說到……
alleged 所謂的，questionably true or of a specified kind(韋氏大學詞典)
consult 查詢
本題結構簡單，重點在于通過alleged和only判斷情感色彩，“所謂的”價值隱含作者對專家意見價值的負評價，only…to see strong evidence 顯示出這種評價的證據(jù)是顯而易見的(排除了AC等模棱兩可的選項)，直接選出來是B失敗。
