Answer:
I believe that the answer would instead be;
Much of the action of the play takes place at a Sanatorium.
The Sanatorium is seen at the end of Act One, all throughout Act Two, and all throughout Act Three.
Step-by-step explanation:
The previous answer says "The play takes place over the course of four months.", but the 3 acts in total take place across around 8 months and a week, as Act One is across a week, Act Two is across 4 months, and Act Three is across 4 months. So that answer is wrong.
The option "There are two scenes in each Act.", is wrong because the 3rd Act doesn't have 2 scenes.
The option "One of the Carmodys' children is sick.", is incorrect as it never discusses the children in this excerpt.
