[单选题]The author tends to think that the fifth level________

回答下面的题目Human needs seem endless．They might be regarded as making up several levels．When there is　enough money to satisfy one level of needs, another level appears．The first and most basic level of needs involves food．Once this level is satisfied, the second level　of needs, clothing and some sort of shelter, appears．By the end of World War Ⅱ , these needs were satisfied for a great majority of Americans．Then a third level appeared．It included such items as automobiles and new houses．By 1957 or 1958 this third level of needs was fairly well satisfied．Then, in the late 1950s, a　fourth level of needs appeared: the "life-enriching level．While the other levels involve physical satisfaction, that is, the feeding, comfort, safety, and transportation, this level stresses mental needs for recognition, achievement, and happiness．It includes a variety of goods and services．Among them are vacation trips, the best medical and dental care, and recreation．Also included here are fancy goods and the latest styles in clothing．On the fourth level, a lot of money is spent on services, while on the first three levels more isspent on goods．A fifth level would probably involve needs that can be achieved best by community action．Consumers may be spending more on taxes to pay for government action against disease, ignorance, crime, and prejudice．After filling our stomachs, our clothes closets, our garages, our teeth, and our minds, we now may seek to ensure the health, safety, and leisure to enjoy more fully the good things on the first four levels．According to the passage, man will begin to think about such needs as housing and clothing only when________

A. would be little better than the fourth level
B. may be a lot more desirable than the first four
C. can be the last and most satisfying level
D. will become attainable before the government takes actions

[单选题]回答{TSE}题Never laugh at a snow covered mountain! Laughter and yelling, during the avalanche season, can cause a deadly pile of snow．Huge snow slides are most common in mountains where there are steep slopes that are well buried in snow and ice．The snow builds up slowly and lands very softly．This can create a very touchy, unstable situation．Tons of snow may be held up by only the friction between snowflakes．The deep snow is like a house of cards．The slightest movement can cause it to fall．As soon as something slips, this great mass of snow will come crashing down the mountainside．Slides may be started by sound vibrations．They may also be started by the weight of wet, melting snow．Once an avalanche has been triggered, the cause no longer matters．Moving down a steep slope, it picks up great speed and added snow．Some avalanches travel as fast as two hundred miles per hour．The force of an avalanche will mow down anything in its path．Whole houses have been swallowed up by these fast-paced piles of snow．The wind that is caused by an avalanche is almost as destructive as the snow itself．Winds from an avalanche have been known to travel as fast as those of a tornado．So, when approaching a thickly snow covered mountain, speak softly!{TS}Avalanches can be started by________

A. falling snow
B. the wind
C. loud sounds
D. friction between snowflakes
