In a well-known adaptation of Hamlet, one actor plays both Hamlet and the ghost. What is the effect of this adaptation

yes the first one is correct .

the author is showing that it is the insatisfaction of basic needs that brings about the protests such as the strikes.if workers do not earn enough to buy food and feed their families and themselves in order to continue working, what is the use of working? besides, another message from the author is that of the owners of factories should be worried about ensuring their furure by having a second and third generation of workers in their industries.if they do not hear the workers demands, they will not have any more workers to make their pockets full.

can you give me a hint
