继续请教aothough，but的用法！是平行么？

although是让步连词，两个句子主语不一定一致
but是转折连词，句子也不需要parallel，请问对么？

但是请大家看这个
Although early soap operas were first aired on evening radio in the 1920's, they had moved to the daytime hours of the 1930's
（A）were first aired on evening radio in the 1920's, they had moved to the daytime hours of the 1930's
(B) were first aired on evening radio in the 1920's, they were moved to the daytime hours in the 1930's
(C) were aired first on evening radio in the 1920's,moving to the daytime hours in the 1930's
(D) were aired first in the evening on 1920's radio,they moved to the daytime hours of the1930's
(E)aired on evening radio first in the 1920^'s, they were moved to the 1930's in the daytime hours
Verb form + Parallelism
The two clauses about soap operas should be parallel.  是although出现就是平行标志么？




而且我看了好多although的句子，发现好像although引导的句子，主从句都是平行的。。。彻底晕了.....这两个词连接句子的时候到底要不要平行？

问啊问啊

同问，although要平行me?
Although improved efficiency in converting harvested trees into wood products may reduce harvest rates, it will stimulate demand by increasing supply and lowering prices, thereby boosting consumption.
A.        in converting harvested trees into wood products may reduce harvest rates, it will stimulate demand by increasing supply and lowering prices, thereby boosting
B.        in converting harvested trees into wood products may reduce harvest rates, demand will be stimulated because of increasing supply and lowering prices, which boost
C.        of converting harvested trees into wood products may reduce harvest rates, it will stimulate demand by increasing supply and lowering prices, which boosts
D.        of harvested trees being converted into wood products may reduce harvest rates, it will stimulate demand, because it will increase supply and lower prices, thereby boosting
E.        when harvested trees are converted into wood products may reduce harvest rates, demand will be stimulated because of increasing supply and lowering prices, which boost


我觉得B中，除了GWD笔记写的 Which指代不清晰，还有问题是，未划线的让步状语从句是主动形式，efficiency reduce，为了保持平行，主句最好也用A中的主动形式

是这样me?
