eunion1-1, Exercise 3: Check a belief against the source

Model answer (one possible answer):

Belief written down: for example, "the EU requires all phone chargers to be the same type".
Source: EUR-Lex or the EU's own pages, where the actual rule (a directive or regulation) can be read in full.
Outcome: note whether the source agreed (the rule exists and says this), corrected you (it applies only to certain devices, or from a certain date), or showed the rule had changed or been repealed.

The point is the method: go back to the original text, read what it requires, check its date and whether it has been amended, and only then decide whether the common version of the story was fair.
