The report, which followed 73,000 women for 17 years, found walking for at least seven hours a week lowered the risk of the disease. The American Cancer Society team said this was the first time reduced risk was specifically linked to walking. UK experts said it was more evidence that lifestyle influenced cancer risk. A recent poll for the charity Ramblers a quarter of adults walk for no more than an hour a week, but being active is known to reduce the risk of a number of cancers. This study, published in Cancer Epidemiology,Biomarkers&Prevention, followed 73.615 women out of 97,785 aged 50-74 who had been recruited by the American Cancer Society between 1992 and 1993,so it could monitor the incidence of cancer in the group. They were asked to complete questionnaires on their health and on how much time they were active and participating in activities such as walking, swimming and aerobics ( 有氧运动) and how much time they spent sitting watching television or reading. They completed the same questionnaires at two-year intervals between 1997 and 2009. Of the women, 47% said walking was their only recreational activity. Those who walked for at least seven hours per week had a 14% lower risk of breast cancer compared to those who walked three or fewer hours per week. Dr. Alpa Patel, a senior epidemiologist at the American Cancer Society in Atlanta, Georgia, who led the study, said: "Given that more than 60% of women report some daily walking, promoting walking as a healthy leisure-time activity could be an effective strategy for increasing physical activity amongst post-menopausal women. We were pleased to find that without any other recreational activity, just walking one hour a day was associated with a lower risk of breast cancer in these women." "More strenuous ( 紧张的) and longeractivities lowered the risk even more." Baroness Delyth Morgan, chief executive of Breast Cancer Campaign, said: "This study adds further evidence that our lifestyle choices can play a part in influencing the risk of breast cancer and even small changes incorporate into our normal day-to-day activity can make a difference."She added: "We know that the best weapon to overcoming breast cancer is the ability to stop it occurring in the first place. The challenge now is how we turn these findings into action and identify other sustainable lifestyle changes that will help us prevent breast cancer."All of the following factors relating to cancer risk were mentioned in the EXCEPT__________.

根据材料,回答问问题。The Science of the Future Until recently, the "science of the future" was supposed to be electronics and artificialintelligence. Today it seems more and more likely that the next great breakthroughs intechnology will be brought through a combination of those two sciences with organic chemistryand genetic engineering. This combination is the science of biotechnology. Organic chemistry enables us to produce marvelous synthetic (合成的) materials. However,it is still difficult to manufacture anything that has the capacity of wool to conserve heat and alsoto absorb moisture. Nothing that we have been able to produce so far comes anywhere near thecombination of strength, lightness and flexibility that we fred in the bodies of ordinary insects.Nevertheless, scientists in the laboratory have already succeeded in "growing" a material that has many of the characteristics of human skin. The next step may well be "biotech heartsand eyes" which can replace diseased organs in human beings. These will not be rejected by thebody, as is the case with organs from humans. The application of biotechnology to energy production seems even more promising. In1996 the famous science-fiction writer, Arthur C. Clarke, many of whose previous predictionshave come true. He said that we may soon be able to develop remarkably cheap and renewablesources of energy. Some of these power sources will be biological. Clarke and others havewarned us repeatedly that sooner or later we wi/1 have to give up our dependence on non-renewable power sources. Coal, oil and gas are indeed convenient. However, using them alsomeans creating dangerously high levels of pollution. It will be impossible to meet the growingdemand for energy without increasing that pollution to catastrophic (灾难性的) levels unlesswe develop power sources that are both cheaper and cleaner. It is attempting to think that biotechnology or some other "science of the future" can solveour problems. Before we surrender to that temptation we should remember nuclear power.Only a few generations ago it seemed to promise/imit/ess, cheap and safe energy. Today thosepromises lie buried in a concrete grave in a place called Chernobyl, in the Ukraine.Biotechnology is unlikely, however, to break its promises in quite the same or such a dangerousway.According to the passage, the science of the future is likely to be__________
