題目如下:
Without seeming unworldly, William James appeared wholly removed from
the____ of society, the conventionality of academe .
A)ethos
B)idealism
C)romance
D)paradoxes
E)commonplaces
書本上解析為: society =academe 同指''學術界''， the conventionality
of academe 乃為一個分隔結構直接重複上文的語義，因此選填與conventionality同義
(E)commonplaces
→但我好奇的是the conventionality 前面的逗號應當是補述前面整句話，而非單
一名詞結構，以這個概念來看，由於前面擺著removed from 取conventoinality非，
我選(B)idealism
希冀版上強者能指導GRE 中逗號在填空解題邏輯架構為何，多謝~~
