But there is no earthquake data... I chose A initially and I understand how it strays from the conclusion-signaling language in the stim and how its actually a misrepresentation of a premise, but I don't see how the last part of B is warranted. Like where is the earthquake data? By earthquake data would we be referring to the lack of earthquake data?

I think the key here is going back the Plant Manager's text to search for what they thing is not fuel efficient.
