Questions 71 to 75 are based on the following passage：
The failed Skylab will come screaming home to earth in disappointmentsometime next month, but it will fall we know not where. That precise information is beyond even the calculations of scientistsand their computers. The best they can tell us is that the space station, weighing 77 tons andas high as a 12-story building, will break into hundreds of pieces that willbe scattered across a track 100 miles wide and 4,000 miles long. We are again exposed to one of those unexpected adventures, or misadven-tures, of science that attracts our attention from the boring routines ofdaily existence and encourages us to think a lot about man's future. What worries Richard Smith, the Skylab's director, is the'big pieces'that will come through the atmosphere. Two lumps, weighing 2 tons each, andten, weighing at least 1,000 pounds each, will come in at speeds of hundredsof miles an hour, and if they crash on land they will dig holes up to 100feet deep. What worries us, with our lack of scientific knowledge and our quickimagination, is both the big and little pieces, although project officialssay there is a very small chance that anyone will be injured by them. That's good to know , but it doesn't remove the doubts of the millionswho still remember the nuclear accident at Three Mile Island. That accidenttook place in 1979 in spite of what scientists had assured us as to thesafety of the nuclear reactor.
