The California region boasts a wide variety of climates and geographical features, rivaling any other area of comparable dimensions. Nearly all but the eastern-edge California Native Americans lived where environmental conditions were favorable, making food relatively accessible. Along the Pacific Coast, they hunted fish and sea mammals by boat. Included were such California tribes as the Chumash, Yurok and Pomo. The Maidu and Pomo principally ate acorns, which have a higher calorie rating than wheat. They pounded the hard nuts with stones and washed out the bitter taste with water.The Pomo crafted what were arguably the finest baskets in all of indigenous America. They made baskets as small as a thimble and as big as a yard in width. They made watertight baskets for cooking acorn mush and seed gruel, as well as for carrying and storing food. They wove especially beautiful baskets for presents and as offerings to forebears. Some were bedecked with colorful bird feathers and shells. Their skill also was applied to trays, boats, headgear and baby carriers, such as a wickerwork cradleboard in which an infant spent his first year. Their mothers wore hats that resembled bowl-shape baskets.The California natives lived in communities numbering up to 2,000 with dwellings arrayed in groups. A house consisted of a round frame covered with grass. There was a skylight in the roof and the beds were made on skin-covered frames—each with a partition for privacy. In the center of the floor, they made a cook fire for seeds, nuts, fish and other foods. More than 100 languages flourished in California before European contact; most are gone today. From the passage we know that their houses were ______.
A. round and strong
B. very dark
C. made of only grass
D. built in groups

Among the most popular books being written today are those which are usually classified as science fiction. Hundreds of titles are published every year and are read by all kinds of people. Furthermore, some of the most successful films in recent years have been based on science fiction stories.It is often thought that science fiction is a fairly new development in literature, but it can be found in books written hundreds of years ago. These books were often concerned with the presentation of some form of ideal society, a theme which is still often found in modern stories.Most of the classics of science fiction, however, have been written within the last hundred years. Books by writers such as Jules Verne and H.G. Wells, to mention just two well-known authors, have been translated into many languages. Modern science fiction writers don"t write about men from Mars or space adventure stories. They are more interested in predicting the results of technical developments on society and the human mind; or in imagining future world which are a reflection of the world which we live in now. Because of this their writing has obviously political undertones.In an age where science fact frequentlyovertakesscience fiction, the writers may find it difficult to keep ahead of scientific advances. Those who are sufficiently clear-sighted to see the way we are going, however, may provide a valuable lesson on how to deal with the problems which society will inevitably face as it tries to master its new technology. According to the passage, we know that ______.
A. science fiction is a fairly new development in literature
B. the history of science fiction is less than a hundred years
C. the science fiction in the past is more popular than modern science fiction
D. modern science fiction usually has obviously political undertones
