Final answer:
The claim that actors in an English acting company were provided with 'sides' containing only their lines and cues, rather than the full script, is true.
Step-by-step explanation:
It is true that in an English acting company, actors were provided with 'sides' that contained only their own lines and cues rather than the full script. This practice was particularly common during the Elizabethan era when resources were limited and the printing of entire scripts would have been expensive and impractical.
Actors would have to memorize their lines from these sides and rely on cues for when to make their entrances and exits during performances. This methodology was a way to protect the playwright's work from being copied or plagiarized, and to focus actors on their roles within the larger tapestry of the play.
