The biggest safety threat facing airlines today may not be a terrorist with a gun, but the man with a portable computer in business class. In the last 15 years, pilots have reported well over 100 【B1】______that could have been caused by electromagnetic interference. The source of this interference remains【B2】______, but increasingly, experts are pointing the blame at portable electronic【B3】______such as portable computers, radio and cassette players and mobile telephones. RTCA, an organization which advises the aviation industry, has recommended that all airlines ban such devices from being used during "【B4】______" stages of flight, particularly take-off and landing. Some experts have gone further, calling for a total ban during all flights. Currently, rules on using these devices are left up to【B5】______airlines.

The difficulty is predicting how electromagnetic fields might affect an aircraft’s computers.

选项
答案
have no way of
解析
分析句子结构可知,主句缺少谓语部分,故可以优先考虑填一动词(短语)前半句说,专家们无法在实验室里复制这种效果,由此可见,后半句应该是说他们无法确定这种干扰是否具有危险性,故所填词应包含“没有办法……”之意。
