A more general question. Simply by watching the anime or reading the light novels or looking through the wiki, a whole bunch of problems presented by the Catastrophe already have solutions for them. Would Elder Tale EU have different solutions to said problems then (such as how to cook food with taste)? Or what.

They would have the same solutions (or different solutions, if the logic is soundproof), but the means would be different.
