Say you swapped "fatalities" to "head injuries" in AC D, would this constitute a necessary assumption? My feeling is probably no because it was never mentioned how many injuries, proportionally, were prevented by the new laws for motorcycle helmets, only that some were prevented. Head injury was also never mentioned as the most common injury for motorcycle riders. Please let me know if I am wrong!

Yeah the LSAT is definitely in its own linguistic world. Also have to find the balance where you know a question is using a suitable synonym (in reference to the text) or is actually trying to see if you misread.
