Sentence Correction (SC) | Re: Unlike the steam locomotive, which required an hour or two

Hi Experts /sayantanc2k / @e-gmat /GMATNinja ,

Can you tell me what's wrong with choice E? My understanding is that adverb/adjectives can come before a Noun in 'Like/Unlike + comma' construction. Is the adverb almost instantly wrong here? I even remember seeing an official question similar to this (can't seem to find now). Please advise.

Thanks!
