"Os quatro artistas têm carreira internacional."

Translation: The four artists have international careers.

[Afoita]

In English the sentence would be correct if it read, "The four artists have international careers"

[bretonparano]

Either An international career or International careers (with s). Answer with s was not considered as mistaken.

[pnehls]

agreed, i think this is a bad sentence when international career is written as a singular thing for four people.

[Danmoller]

In Portuguese there is a very subtle difference between "eles têm carreira internacional" and "eles tem carreiras internacionais".

The first emphasizes a quality they all have in common.
The second emphasizes the "to each his own" idea.

[Lingledingle]

English could do that also, in, "The four artists have AN international career.", with the idea that they are all in the career, perhaps working together or maybe separately.

[AimeLesLangues]

I used "an" and it accepted it.

[mastakhan]

So to be clear, this sentence is fine in Portuguese, but for the English translation we would need to add "an" to convey the proper meaning and grammar?

[Danmoller]

Exactly. (And it shall be fixed soon)

[mckara]

What do artists have to do with sports?
