The correct answer is probably the Candidates website. It would usually be biased towards the side of the candidate and would not include opposing arguments.
None or a thing, or an adverb clause
It takes place<span> when slavery was at its height in America</span>
The answer should be D. The first two answer choices, A and B, are completely opinion based. A claims that the vehicles are very ugly, which is an opinion, and B says that it is all a conspiracy. We can rule out those tow answer choices pretty easily. For C, the fact is false. Not many people get electrocuted while driving the cars. This means D is the only logical answer. It gives a good, factual reason why schools shouldn't switch to electric vehicles. I hope this helps!
