"Lupul nu este un animal rău!"

Translation: The wolf is not a bad animal!

[JamesTWils]

Here, I would actually say "the wolf," speaking of the species in general.

[gluadys]

Me too, But the English is ambiguous here. It could refer to a specific wolf as well. However, I would probably say "This/that wolf" in that case.

Why "Lupul nu e un animal rău" is not accepted?
