Is the word passaram the same in Brazilian and European Portuguese?

No

While the spelling, grammar, and core meaning of "passaram" are identical in both dialects, there are differences in typical usage regarding prepositions and certain grammatical constructions. In Brazil, "passar na" is a common way to say someone "stopped by" a location (e.g., passar na minha casa). In Portugal, "passar por" is the standard way to express passing by or visiting a place. Additionally, in European Portuguese, "passaram a [verb]" is a frequent construction used to indicate that an action started (e.g., passaram a estudar), whereas a Brazilian would more likely use "começaram a" (started to).
