For people who use K12, this is the correct answer:))
I had this on my test too, and I scored a 100!
Answer:
D
Explanation:
The space was a well-constructed thrust stage however, the stage was not raised off the ground and the seats appeared to be mobile which lead to the belief that this is an Environmental Theater. As for the layout of the stage, there was a couch and a table in center stage for the first two acts, a door to the unseen outside front of the house upstage right, there were two large double doors upstage center leading to the backyard garden, and a raised floor upstage left containing a piano, a bookcase and a door leading to the home library. Stage left there was a half spiral staircase that lead up to the second floor which had a painting and lights that extended across to stage right. The second floor also contained the bedrooms for the house but the doors were not in sight. The detail was greater than expected: the hardwood floor throughout the first floor seemed to be genuine, the actual bookcase filled with real books not stage books, and the extremely large double doors with translucent glass and floral designs lead to the Garden, which featured an array of plants behind the doors. The entire space was well lit for the duration of the play; the stage took place inside the Bliss’ home so the bright lighting added a confortable feel to the inside of the house. The theatre was nearly sold out; it was hard to spot an empty seat, including the balcony and lower level seating. The crowd contained nearly an even amount of student audience members and senior citizens; there was few in the audience that appeared middle aged.
