单选题{{B}}Passage Four{{/B}} At its best, any prison is so unnatural a form of segregation from normal life that-- like too-loving parents and too zealous religion and all other well-meant violations of individuality-it helps to prevent the vicitims from resuming when they are let out, any natural role in human society. At its worst, the prison is almost scientifically designed to develop by force--ripening every one of the antisocial traits for which we suppose ourselves to put people into prison (I say "suppose", because actually we put people into prison only because we don't know what else to do with them). The prison makes the man who is sexually abnormal, sexually a maniac. The prison makes the man who enjoyed beating fellow drunks in a bar-room come out wanting to kill a policeman. Probably we cannot tomorrow turn all the so-called criminals loose and close the jails--though, of course that is just what we are doing by letting them go at the end of their sentences. No society cannot free the victims. Society has unfitted liar freedom. Doubtless, since the Millennium is still centuries ahead, it is advisable to make prisons as sanitary and well-lighted as possible, that the convicts may live out their living death more comfortably. Only keep your philosophy straight. Do not imagine that when you have by carelessness in no inoculating them, let your victims get smallpox, you are going to save them or exonerate yourselves by bathing their brows, however grateful the bathing may be.

单选题British cancer researchers have found that childhood leukaemia is caused by an infection, and clusters of cases around industrial sites are the result of population mixing that increases exposure. The research published in the British Journal of Cancer backs up a 1988 theory that some as-yet unidentified infection caused leukaemia—not the environmental factors widely blamed for the disease. "Childhood leukaemia appears to be an unusual result of a common infection," said Sir Richard Doll, an internationally-known cancer expert who first linked tobacco with lung cancer in 1950. "A, virus is the most likely explanation. You would get an increased risk of it if you suddenly put a lot of people from large towns in a rural area, where you might have people who had not been exposed to the infection. "Doll was commenting on the new findings by researchers at Newcastle University, which focused on a cluster of leukaemia cases around the Sellafield nuclear reprocessing plant in Cumbria in northern England. Scientists have been trying to establish why there was more leukaemia in children around the Sellafield area, but have failed to establish a link with radiation or pollution. The Newcastle University research by Heather Dickinson and Louise Parker showed the cluster of cases could have been predicted because of the mount of population mixing going on in the area, as large numbers of construction workers and nuclear staff moved into a rural setting. "Our study shows that population mixing can account for the (Sellafield) leukaemia cluster and that all children, whether their parents are newcomers or locals, are at a higher risk if they are born in an area of high population mixing, "Dickinson said in a statement issued by the Cancer Research Campaign, which publishes the British Journal of Cancer. Their paper adds crucial weight to the 1988 theory put forward by Leo Kinlen, a cancer epidemiologist at Oxford University, who said that exposure to a common unidentified infection through population mixing resulted in the disease.
