The thirteen original British colonies in North America,some formed as commercial ventures,others as religious havens,each had a written charter that set forth its form of government and the rights of the colonists.

B.some being formed as a commercial venture,others as religious havens,all of which had written charters

D.with some being formed as a commercial venture,others as religious havens,all had a written charter
E.with some formed as commercial ventures,while others as religious havens,each had a written charter
此题选A.一个疑问.因为句尾的its,决定了选each.但是set forth的主语是谁?如果是each,不应该用第三人称单数么

我晕!
each had a written charter that set forth its form of government and the rights of the colonists.
这里set forth的主语不就是that前面的名词a writtern charter么.前面用了had,所以这里就像1楼说的set是过去式.本来定语从句that就是修饰前面的一个名词.而在GMAT语法中,定语从句就算是用which引导的,99%也只修饰逗号前面的名词,而不会修饰逗号前面的整个句子.
例如:The coat is very expensive,which costs me 1000 yuan.这种非限定性定语从句,从句逗号隔开的两个句子如果单拿出来会分别是两个句意完整的独立句子；但如果是限定性主句和从句分开则不是完整的句子.
例如:The coat is a birthday present which my mother sends.GMAT考试中为了避免出现歧义,更多的出现的是这种句子,即WHICH只指代(逗号)前面的那个名词,此句中,则是present.
其实GMAT语法考的不是语法,而是语意和逻辑.这道题读完5个选项,只能选A了.其他的逻辑意思都存在各种问题,这里就不详细说了.

set forth主语是charter，set用的是过去式
