在OG的第96頁有一題
For some time now, _____ has been presumed not to exist: the cynical
conviction that everybody has an angle is considered wisdom.
選項有 (A) rationality; (B) flexibility; (C) diffidence; (D) disinterestedness
(E) insincerity
我瞭解答案是disinterestedness
但是請問這句的主詞是不是"disinterestedness has been...has an angle"呢？
謝謝 :)
