D选项平行
E选项usage of spices is in small quantities语义模糊,可能表示spices不经常用,一旦用就会用很多,与想表达的意思不符。
A选项 比较对象不平行using和they比较;主语前面不能加介词
B选项 后面的they没指出in medicine;主语前面不能有介词短语; in using应该有who,否则用usage;using spices for medicine表示spices用于medicine的生产
C 为什么对 Maya is a group of people or Mayans (Americans, Britans etc).
In this case the arhcitects and stonesmasons are used to describe them as a people.
ex. The maya are known to be architects and stonemasons.
E is wrong because of "were the maya who" -- this doesn't clearly refer back to "Architects and Stonemasons". You can make the connection in your head yes, but grammatically this is wordy/awkward and incorrect.
