109. Recently a court ruled that current law allows companies to reject a job applicant if working in the job would entail a 90 percent chance that the applicant would suffer a hear heart . The presding judge justified the ruling, saying that it protected both employees and employers.

The use of this court ruling as part of the law could not be effective in regulating employement pratices if which of the following were true?


B:No really accepted methods exists for calculating the risk of a job applicant's having a heart attack as a result of being employed in any particular occupation.

不明白B为何是假设,OG的解释我也不太明白.能帮助讲讲吗?谢谢.
