"Ela vai dizer onde pode produzir."

[markmanson]

No pronoun in this sentence means it could have multiple meanings. For example "She will say where she can produce"

[devonreed]

"She will say where it can be produced"?

[Lingodingle]

Right, and also their sentences do not make sense in English. Yours does. As the Portuguese is stated the subject of that second clause could be he, she you or it.
