I took a first look at the Hungarian vs. English versions. The first impression is that the translator didn't really knew the corresponding Hungarian technical expressions (and was guessing).

Question 3 has some silly errors: it turned "investments in infrastructure and generation capacity" into something like "investments in infrastructural and generation capacity"; and "Increase the share of EU financial support" was translated by dropping "the share of".

Regarding question 4, I ask a question does 'competitive' there have the meaning "competition-based" (e.g. marketised)? If yes, another minor mistranslation. In the choices, methinks significant omission: from "Focus on cost effective savings of energy", cost-effective is dropped. In "Decrease dependency on imported fuels", 'imported fuels' becomes 'imports' (that would include electricity, but I don't see this difference as a big problem).

English vs. Hungarian versions, continued.

Question 6: this is the worst change so far. Above all in the second option ("Develop smart electricity networks, demand management and distributed energy generation, bearing in mind their potential to help at times of sudden shortage"):  First, the sentence has been turned around, with the original second sub-sentence changed to something like: "At times of sudden shortage, it could help to...". Second, two really bad cases of not knowing technical expressions: 'demand management' became something that can also be read as "income farming", and 'distributed energy generation' tunred into "divided energy generation"... In the fourth option, "likely shortfalls" turns into "foreseeable shortfalls", not insignificant.

Question 7, first option about "a solidarity mechanism to assist a Member State facing difficulties following disruptions of its energy supplies under emergency circumstances": emergency circumstances is dropped, plus loose wording: facing difficulties becomes "gets in trouble". Third option, 'emergency demand restraint' is horribly mistranslated, something like "keeping emergency income in bounds"... Fourth option, "early notice" becomes "early forecast"...

Question 8: nuance cut, "Europe, taken as a whole, promotes the diversification of energy supplies" becomes something like "Europe's energy supplies become more diverse".

I already wrote about question 9.

Question 12: "Disposal of nuclear waste" becomes "management of nuclear waste" (which is NOT the same!)

Question 14, last option, another horrible mistranslation totally changes the meaning: "Member States should be able to rely on at least three different supply sources" becomes something like "the Member States must purchase from at least three sources"...

(Next, I'll look at the German version.)

English vs. German versions: overall, much much better. Only three little problems with wording:

Question 6, sixth option: 'emergency disruption' becomes 'unforeseen disruption'.

Question 9, first option: " widest possible international actions" becomes "weitestreichenden internationalen Aktionen", I think should have been "weitestreichend internationalen Maßnahmen" (the first is about actions with the widest reach, the second about widest participation in the action, where in my reading the original English means the latter).

Question 12: 'Smart electricity networks' is translated as "Ausgeklügelte Elektrizitätsnetzwerke", instead of "Intelligente Elektrizitätsnetzwerke" (the first does mean smart, but not in place in this context, it has a meaning roughly like "well-thought-out")
