Hello. You did not submit the text to source b to which the question refers, which makes it impossible for it to be answered. However, I will try and help as best I can.
To answer this question, you need to read the text presented in source b and find the techniques presented by the poor theater. These techniques will be a set of procedures that those involved with poor theater will need to do to achieve the objectives of poor theater.
It is important to remember that poor theater was created by Grotowski to express a theater group that presented plays without excesses, that is, without luxurious sets and costumes, but showing the actors' acting skills and the essence of the characters. The techniques of this type of theater should be associated with a presentation with few accessories but with maximum acting.
