SAT OG語法題
OG 892
5.In the wild,pygmy chimpanzees are found only in an inaccessible region south of the Zaire River, since such is the case,very few are in captivity.
 (A) since such is the case,very few are in captivity
  (B) and very few are in captivity because of that
 (C) no more than a few are in captivity as a result
(D) the number in captivity is very few for this reason
 (E) and so no more than a few are in captivity
A和C的錯誤在哪里?還有正確答案的E“and”和“so‘在一起不算介詞連用么?
“and”和“so‘在一起不算連詞連用么？還是說“and so”一起作為一個連詞，可是字典說“and so”是個副詞……
