Direction: Read the following passage and answer the questions given below.

Theaters have evolved with different internal layouts according to the types of productions presented there. Proscenium stages have an architectural frame, known as the proscenium arch, although they are not always arched in shape. Their stages are deep and sometimes raked, meaning the stage is gently sloped, rising away from the audience. Sometimes the front of the stage extends past the proscenium into the auditorium. This is known as an apron or forestage. Theaters containing proscenium stages are known as proscenium arch theaters and often include an orchestra pit for live music and a fly tower for the movement of scenery and lighting.

As the name suggests, the thrust stages are projected, or ‘thrust’ into the auditorium, with the audience sitting on three sides. The thrust stage area itself is not always square but may be semi-circular or half a polygon with any number of sides. Such stages are often used to increase intimacy between actors and the audience. Theaters in the round have a central performance area enclosed by the audience on all sides. The arrangement is rarely ‘round’: more usually, the seating is in a square or polygonal formation. The actors enter through aisles or vomitories between the seating.
