A reliable source (WP:RS). The encyclopedia is about the citations; it's a travel atlas to the sources about a subject. Any conclusions the encyclopedia draws "itself" are secondary to the sources.
No, I merely being sarcastic, because I know it's all boils down to power. Just ask yourself, why different language wikipedias diverge on some hot topics.
Because they're run by completely separate teams of moderators and Wikimedia (as in the organization) basically never interferes with other versions of Wikipedia?
Because every other language has far worse moderation, and you can pretty much guess how good the moderation is simply by asking yourself how relevant that version of Wikipedia even is in the first place?
I can understand 6 different versions of Wikipedia and my experience is the complete opposite of what you're insinuating, English version beats the other five 99.8% of the time even the topic at hand is completely local.

You are almost there. Yes, different groups of people can have different opinions on which sources are reliable, and reach different conclusions based on different sources.
