请问og56题 e选项 为何不好（老问题）

E is awkwardly phrased and produces a sentence fragment, because the appositive noun phrase Architects and stonemasons cannot serve as the subject of were the Maya.

为什么？

56. Architects and stonemasons, huge palace and temple clusters were built by the Maya without benefit of the wheel or animal transport.

(A) huge palace and temple clusters were built by the Maya without benefit of the wheel or animal transport

(B) without the benefits of animal transport or the wheel, huge palace and temple clusters were built by the Maya

(C)the Maya built huge palace and temple clusters without the benefit of animal transport or the wheel

(D) there were built, without the benefit of the wheel or animal transport, huge palace and temple clusters by the Maya

(E)  were the Maya who, without the benefit of the wheel or animal transport, built huge palace and temple clusters

A, B, and D illogically suggest that the palace and temple clusters were architects and stonemasons. For the modification to be logical. Architects and stonemasons must immediately precede the Maya, the noun phrase it is meant to modify. A, B, and D also use the passive verb form were built, which produces unnecessary awkwardness and wordiness. E is awkwardly phrased and produces a sentence fragment, because the appositive noun phrase Architects and stonemasons cannot serve as the subject of were the Maya. C, the best answer, places the Maya immediately after its modifier and uses the active verb form built.

有何不可？

Architects and stonemasons,   (E)  were the Maya who, without the benefit of the wheel or animal transport, built huge palace and temple clusters

多了这逗号, 句子结构零散

I think E changes the focus of this sentence.  In A, The maya built ... is the main idea.  In E, maya were architects is the main meaning.

不是不是…………

(E) Known as “The Iron Horse,” baseball star Lou Gehrig’s endurance and consistency are legendary.

B a baseball star known as “The Iron Horse”究竟是谁的同位语？也就说，把is改为are，b是否正确呢？？

同位语在句首修饰主句主语，同时不也就是就近修饰吗？
