"E" for me. Waiting for the OA.National debates are the engine that powers political campaigns,
dissecting issues and not oversimplifying them, as in campaign commercials.
A. dissecting issues and not oversimplifying them, as in campaign commercials
Read this choice as "National debates are the engine that powers political campaigns, dissecting issues and not oversimplifying them, as in campaign commercials"
If we read this sentence without the strike part, it is comparing engine that powers political campaigns with campaign commercials. We can't see the contrast here. This is basically +ve comparison and not contrast.B. dissecting issues instead of oversimplifying them, like campaign commercials
Same as option AC. dissecting issues rather than oversimplifying them, as campaign commercials do
Same as option AD. and dissects the issues but does not oversimplify them, as is done in campaign commercials
Same as option AE. and dissects the issues, unlike campaign commercials that oversimplify them
Correct. Th intended contrast can be seen clearly here. "engine" unlike "campaign commercials". We need to compare a noun with another noun, so we need a like NOT as. The action is not being compared. If we were comparing actions, we would have used "as".
