distinguish 也有 distinguish A from B 的用法

discard2

A former director of the Central Intelligence Agency has said that the surveillance capabilities of United States satellites would enable a skilled photographic interpreter to distinguish(between Guernsey and Hereford cows grazing) in a meadow.
A.between Guernsey and Hereford cows grazing
B.between Guernseys and Hereford cows that graze
E. Guernsey from Hereford cows grazing
why the answer is A?为什么E 不对？distinguish 也有 distinguish A from B 的用法

如果是distinguish a From B 的话, 那么Guernsey 就在Hereford cows 的里面了, 要把他分离出来才用distinguish from

discard2

有道理，那为什么不选B呢？用现在分词和定语从句修饰的区别在哪里呢？

现在分词在OG要旨中简洁明了于从句.

此题可以这样考虑,因为distinguish A from B 要求两者间具有同质性,可是Hereford cows grazing in a meadow中的Hereford cows 有定语,而前面的Guernsey 没定语,违反了平行结构的要求.
