Directions: Read the following selection, and answer the question that follows. Blue-Screen Technology

The camera rolls as an actor stands in front of a blue screen. The actor stands alone, saying his lines. However, when you see the actual movie, he is talking to a formidable seven-foot-tall monster in a creepy dark forest. A process called blue-screen technology is used to insert images into a background. Today, moviemakers use this process to combine digitally created, or computer-generated, characters with real people on the screen. Here's how it works:

The scene calls for a real character to interact with a seven-foot-tall digitally created monster. First, the real character's part must be filmed. He may rehearse with another actor who plays the part of the monster. During the rehearsal, the "monster" might wear a tall hat to represent the stature of the monster. The real actor practices looking at the top of the hat during the scene so that it seems that he is looking up at a very tall creature. The actor gets used to where the monster stands and moves. The monster's movements are marked on the floor so that the actor doesn't walk on top of the monster during the scene. Then it is time for the scene to be shot. The actor stands alone in front of a blue screen and delivers his lines as if the monster were there. Eventually, the blue background is deleted, using a computer, and images of the digital monster and background are then transferred to the film.

Which of the following is a reasonable conclusion to draw from the reading?
a.
Scenes with seven-foot-tall monsters are easy to add with blue-screen technology.
b.
Movies are more fun to watch because of blue-screen technology.
c.
Adding special effects to movies using blue-screen technology isn't worth the effort.
d.
As a result of blue-screen technology, adding special effects to movies is easier and faster.
