[单选题]German people prefer extensive green roof systems to intensive ones.
回答下面的题目:Green Roof ResearchThe concept of green roofs is basically about growing plants on roofs, thus helping to replace the green footprint that had been destroyed due to the construction of the building. Green roofs are the most prevalent( 流行 ) in Germany, which is widely regarded as the leader in green roof research.The green roofs that are used these days can be classified as "extensive" and "intensive" systems. Extensive green roofs use mosses, grasses and herbs, which are tolerant to droughts. These plants do not need much maintenance, can be grown in a layer of substrate ( 土层 ) that can be as shallow as 1.5 inches, and generally are inaccessible to the public. In contrast, a wide range of species of plants are grown on intensive green roofs, such as shrubs ( 灌木 ) and even trees, which require deeper substrate layers, and are usually grown on flat roofs. They need intensive maintenance, and are usually areas that resemble parks which are accessible to people.There are several benefits of adopting green roof technologies. Apart from the obvious psychological and aesthetic (美学的 ) benefits of garden-like environments surrounding you, some of the common economic and ecological benefits are: a reduction in the consumption of energy; air and water purification; recovering green spaces; and the mitigation ( 缓解) of the heat island effect in urban areas.The green roof research that is currently ongoing is focused on evaluating the species of plants that are suitable to be grown on roofs, the methods of propagation ( 繁殖 ) as well as establishment, nutrient (养料 ) and water requirement, substrates, and the quantity and quality of water runoff. The evaluation criteria of plant species are: at what rate they can be established their capacity to withstand invasive weeds; tolerance of cold and heat; tolerance of drought conditions; capacity of persistence and survival.A number of experiments are being conducted on roof platform simulations at various research centers. These sites are generally outfitted with equipment, which are used to measure temperatures at different depths of the growing substrates, and the rate and volume of the runoff of stormwaters from each of the platforms.Green roof technology is representative of a completely new market for landscape contractors, and all roofs that currently exist and the future ones to be constructed are the potential market-a market that is too huge to be overlooked.It is estimated that around 10 percent of the flat roofs in Germany are green.

A New Strategy to Overcome Breast Cancer根据以下材料回答下面的题目：Post-menopausal ( 绝经后 ) women who walk for an hour a day can cut their chance of breast cancer significantly, a study has suggested. 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 longer activities 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 passage EXCEPT__________
