as well as 不表示平行
非常正确 + 3个鸡腿 ！！！as well as and

as well as这里的用法是因为emit是修饰成分，并不是burn up的并列。因此用的emitting，在逻辑上表并列时，还是应该与前面表平行。
gases复数可数，表示气体的种类，所以用fewer
错选D
as well as emiting这一结构可不可以类似看成是连词+分词的伴随结构，修饰burn的？
不是连词 是介词吧 连词要连接两个句子 而且 as well as前面有个逗号

It is an idiomatic usage that when we use a verb after 'as well as', we always use and verb+ing form. Emitting is a gerund here because as well as is preposition rather than conjunction in this context and a preposition is always followed by a noun of an action noun 'gerund'. A question of parallelism arises only when a coordinate conjunction is involved and not with a prepositional phrase.
so, i can't think of a situation in which "having __ed" (without a comma) makes much sense, since that would imply that "having __ed" is a temporary state. hm.
so, here's the thing: once you have done something... well, that's true forever.
e.g., if you have seen a certain movie, or if you have smoked cigarettes, or if you have done just about anything... then you never STOP being "someone who has seen the movie", or "someone who has smoked cigarettes", etc.
these descriptions remain true in perpetuity. forever and ever and ever amen.
as well as' is not strictly a parallel marker.
the most straightforward thing in choice B:
"gas" is singular, so "far fewer of the other gas" is nonsense. (you can't have "fewer" unless you can count things, and you can't count things unless they're plural.)
但是正确选项A里用的也是far fewer other gases啊
gas在B里是单数形式指气体可以理解为和二氧化碳那个部分一样就是排放量不可数，在A里的gases复数形式代表气体种类所以能加fewer
manhattanprep的原题里面 b是"other gas", 不要误导
B选项: of comparable size as well as emit far less carbon dioxide gas and far fewer of the other gas having

note that you can't read this as "less (carbon dioxide ... and other gases...)", either -- i.e., with "less" applying to both things -- because "less other gases" doesn't make sense.
you could have "fewer gases" (= not as many different kinds), or "less OF the gases" (= a smaller total quantity)... but not "less gases".
the most straightforward thing in choice D:
"far less carbon dioxide and other gases that have..." appears to indicate that the engines emit other gases (not LESS OF those other gases).
此题不应该错，是道简单题目，错选A了。burn 和 emit 连接并列做 Diesel enginess 的谓语。
你看错答案了 A是正确选项 emitting是burn的修饰

as well as doing something 位于逗号后，对主句的谓语动作做出补充
as well as这里的用法是因为emit是修饰成分，并不是burn up的并列。因此用的emitting，在逻辑上表并列时，还是应该与前面表平行。
as well as 后面不能跟 verb
此题除了fewer/less之外，有其他考点吗？
有啊，and和as well as的措辞，还有平行。
