3 remove 'all' or 'out'

4 są zatwierdzane/uchwalane
5 podmiot w zlym miejscu w pytanie, a w ogole po co strona bierna?

pozost ok

Zadanie jest z działu passive voice, dlatego strona bierna. Dziękuję za pomoc. A jeśli chodzi o 4 to zatwierdzać to approve, prawda? Mam napisać :No decisions are approved without his approval.?? To nie bez sensu?

w takim razie w 2 brakuje czasownika

są inne slowa niz approve. są slowniki kolokacji.

Wejdz np na cambridge i zobacz jaki czasownik lepiej pasuje do decision.

4. No decisions are made without his approval. ?

niech będzie, ale myslałem o adopted/passed

Dziękuje za wszelką pomoc :)
