求教，这一题我很怀疑答案是不是错了

lr081919

The Emperor Augustus, it appears, commissioned an idealized sculpture portrait, the features of which are so unrealistic as to constitute what one scholar calls an "artificial face."
(A)so unrealistic as to constitute

(B)so unrealistic they constituted

(C)so unrealistic that they have constituted

(D)unrealistic enough so that they constitute
（E）unrealistic enough so as to constitute

答案选A我觉得A也是错的！！

沒錯阿 BC中用了過去時和濄完時 不知道為什麼 因為一般現在式即可 然後用短語so as to 結構比so that。。。從句簡潔明瞭
DE中使用了enough 這樣的口頭詞彙
A就沒錯阿

但是constitude不是应该有一个逻辑主语的吗？

greatbelief

so as to 用于单一主谓结构，constitute 的逻辑主语应该是features. 不可能是The Emperor Augustus，这样意思就更不对了。
