Actors sometimes have to take on ___________ roles in a play if there are not enough people to play all the different parts.equalraremultiplelocal

The best word to fill in the blank is "multiple."

When actors take on "multiple" roles in a play, they play more than one character. This often occurs in smaller productions or when there are not enough actors available to fill all the parts. Such versatility allows the production to continue smoothly without casting issues and can also showcase the actors' range and talent. Playing multiple roles can be challenging, as it requires an actor to quickly switch between different characters, each with their own distinct personality, mannerisms, and motivations.

In summary, "multiple" fits perfectly in the context of the sentence, indicating that actors may need to assume more than one role due to limited cast availability.
