单选题{{B}}Passage Four{{/B}} Most of the plans and programs for diminishing crime by means of comprehensive community organization have made prevention their major purpose. However, the underlying concepts on which such programs are based suffer from inconsistency (不一致，矛盾) and confusion. It would be inaccurate to speak as if concise, clear, and explicit models for crime prevention existed especially since writing and discussion on the subject often have been more ideological than scientific. One conception heavily weighted with ideology is the argument that crime can be prevented by massive or total programs of social and economic improvement directed at the root causes of crime in society as a whole. The assumption is that eliminating harmful social conditions such as poverty, malnutrition, disease, poor housing, family disorganization, unemployment, and racial discrimination will make crime disappear. Crime is traced to a pathological (病态的) or broken social structure, and only a thorough renovation or replacement of that structure will usher in a crimeless society. This conception has revolutionary implications going back to older socialist beliefs that poverty or class exploitation causes crime. Among the methods it advocates to solve social problems is the activation of some forms of popular democracy. Another form of social improvement more sophisticated in conception has been loosely designated as "opportunity theory ". This conception holds that crime results from psychic pressures in individuals who are culturally indoctrinated (灌输) with achievement values and yet have, no opportunity for upward mobility because of their unfortunate position in a rigid social structure. Those so disadvantaged are primarily youths in the lower socio-economic strata. Amelioration (改善) inspired by opportunity theory employs vaguely martial imagery: it speaks of the "mobilization" of community resources to make "war" on poverty. Broad-scale programs of social and cultural improvement may be desirable or necessary at times, but since they fail to explain why some poverty-stricken youths turn to crime while others do not, their efficacy (功效) in eradicating and preventing crime is questionable at best. So far only one country, the Soviet Union, has conducted a large-scale revolutionary experiment in social improvement, and the results have not been affirmative: Soviet authorities are still plagued by juvenile crime. This experiment suggests that social improvement is too scattered in its impact to be an effective means of crime prevention.

单选题 More boys than girls are born all over the world, but a new study has found that the closer people live to the equator (赤道), the smaller the difference becomes. No one knows why. The imbalanced sex ratio at birth has been known for more than a hundred years, and researchers have found a large variety of social, economic and biological factors that relate to the sex ratio at birth—war, economic stress, age, diet, selective abortion and more. But latitude (纬度) is a natural phenomenon, unaffected by cultural or economic factors. To look at the effect of latitude, Kristen J. Navara of the University of Georgia used the latitude of the capital city in 202 countries, as well as 10 years of data on sex ratio at birth and annual variations in day length and temperature. Dr. Navara performed a statistical analysis which showed that there was a significant relation between sex ratios in favor of boys and latitude. African countries produced the lowest sex ratios—50.7 percent boys—and European and Asian countries had the highest with 51.4 percent. There are some possible explanations, but none entirely satisfactory. It could be that there is some survival value in producing more girls in warmer regions, but it is unclear what this might be. There may be genetic or racial differences that could explain it, but the connection persists over so many varied populations that this seems unlikely. Mice also produce more male offspring during shorter days or colder weather, but the reasons in these animals are just as mysterious as they are in humans. "There's a possibility that humans might be responding to factors they were programmed to respond to a long time ago—not cultural or socioeconomic, but climate and things like latitude," Dr. Navara said. "What's interesting is that we may be seeing something that connects us with our animal ancestry."
