This scenario also sees an accelerating pace of change in the power

Hello, YuChenChen. We have no way of assessing what this sentence means to convey, since it appears to have been taken from some news source without any surrounding context. Why does the sentence start with the demonstrative this scenario? What scenario? I feel as if I am missing some information that is crucial to evaluating the sentence. Maybe it does mean to wrap up by discussing a year (in which case I would expect to see by 2050, which is not even an option). But it is just as likely that this 2050 figure refers to some unseen information that pertains to electricity demand. I would not bother working out this one when the poster, in all likelihood, lifted some sentence from something he or she was reading and decided to build a question around it. I am not even certain whether the usage at the end is a result of a difference in regional English or dialect, or whether the source material was not edited too well. Some sentences, even those found in reputable sources, are not worth turning into SC questions, at least without significantly altering the source material.

I would advise anyone to, well, just see my signature below. Trust the material that GMAC™ produces for the test for which you intend to prepare. There are plenty of questions to cover, and nothing compares in quality for the task at hand.
