    In 1967, in response to widespread public concern aroused by medical reports of asbestos-related deaths, the National Medical Re search Council organised a committee of enquiry to investigate the health threats associated with the use of asbestos in the building industry.
    (41)______. The report confirmed the findings of similar research in the United States and Canada. Exposure to relatively small quantities of asbestos fibres, they concluded, was directly responsible for the development of cancers, asbestosis and related diseases. Taking into account evidence provided by economists and building industry management, however, the report assumed that despite the availability of other materials, asbestos would continue to play a major role in the British building industry for many years to come because of its availability and low cost.
    (42)______. They recommended that, where possible, asbestos free materials should be employed. In cases where asbestos was employed, it was recommended that it should be used in such a way that loose fibres were less likely to enter the air. The report recommended that special care should be taken during work in environments which contain asbestos. (43)______.
    The report identified five factors which determine the level of risk involved. The state and type of asbestos is critical to determining, the risk factors. In addition, dust formation was found to be limited where the asbestos was used when wet rather than dry.
    (44)______. Machine tools produce greater quantities of dust than hand tools and, where possible, the use of the latter was recommended.
    A critical factor takes place in risk reduction is the adequate ventilation of the working environment. (45)______. By closely following these advices, it was claimed that exposure can be reduced to a reasonably practical minimum.

A. Workers should wear protective equipment and take special care to remove dust from the environment and clothing with the use of vacuum cleaner.
B. After examining evidences provided by medical researchers and building workers and management, the Council published a report which included advices for dealing with asbestos.
C. When work takes place in an enclosed space, more asbestos particles circulate and it was therefore recommended that natural or machine ventilation should be used.
D. The building management preferred to use machine tools because machine tools were much more efficient.
E. The choice of tools was also found to affect the quantities of asbestos particles that enter the air.
F. When work takes place in an enclosed space, less asbestos particles circulate and it was therefore recommended that natural or machine ventilation need not to be used.
G. As a result, the council gave a series of recommendations which were intended to reduce the risks to those who might be exposed to asbestos in working environments.
选项
答案B
解析 本句解题的关键就在于分析下文，特别是在下文第一句中出现的the report一词，可以得到结论，前面这句话中，肯定已经提到了调查委员会提交了一个报告。再分析七个选项，只有选项B是最符合这个要求的，所以B是正确答案。
