[单项选择]Hollywood is a suburb of the city of Los Angeles in California. Until 1908 it was no more than a quiet village on the northern side of the city, but in that year William Selig, one of the first people to make films, set up a film-producing workshop in Los Angeles. By 1911, David and William Horsely had set up another one in Hollywood, and at about the same time oil was discovered in the neighborhood. Thus Hollywood quickly became a big district given over to the film industry and to oil wells.
The early makers of films found Hollywood a good place for their work because of its clear, sunny, rain-free weather, which allowed pictures to be taken all the year round. Also, it was known that every kind of scene needed for films, whether town, country, sea, desert or snowcapped mountains, could be found within the area of California. Today, when most films can be "shot" under cover by man-made lighting, these advantages are not so important.
In spite of a drop in its importance,
A. Hollywood is becoming less advantageous than before
B. Hollywood makes more television films than cinema films
C. Hollywood is famous for both its oil industry and film industry
D. Hollywood has been the most important film production place since early this century
