Complete the relative clause with no repeated subject pronoun: The supervisor ___ starts at six. Use exactly who followed by manages and the noun phrase the night shift, with no added words.
الإجابة الصحيحة
who manages the night shift
الشرح
Who is itself the subject of manages and connects that action to the supervisor. Adding he or she after who would be the closest error because it would create a second coreferential subject.
