4/10 here.
And even though I got 6 of them wrong, the one that bothers me the most - weirdly enough (because I've got no interest in any Chinese stuff) - is the fact that China uses only 1 timezone despite of how large of a landmass it is. Like, how TF is this even possible??
I think this was a trick question, and the tricky part about it - if I were to guess - I'd say is the use of the word "official" in the question. Because I have a feeling that most nations that have more than 1 timezone only use 1 of them as official, so this is probably the same with China too even if (unofficially) there is more than 1 timezone.
If this was a trick question it got me good, which is why I'm so pissed about it, I fell for it like a complete rookie
