Given some of them are disputed (heaviest type of wood is one of about three depending on who you ask and when (some are nearly extinct and like all natural things, vary considerably)), some require knowing knowledge from Edison's timeframe (what planet was recently found to be enormous size - certainly wasn't Jupiter - possibly Neptune) and a couple are opinions (what country and city produce the finest china), I feel like there is a lot of leeway in the answers, but knowing all but three seems unlikely.
