Prep2012-Pack1-CR-020 Easy Public health official:Some researchers suspect that magnetic fields from high-voltage power lines cancause health problems for people who live especially near the fines. However,this is extremely unlikely: Beyond a distance of a few feet,[url=]the strengthof the magnetic fields[/url]from high-voltage powerlines is less than the average strength of magnetic fields in homes that arenot located near such lines. Which of the following would it be most useful toestablish in order to evaluate thepublic health argument? A. Whether magnetic fields in homes that are not locatednear high-voltage power lines can cause health problems for the residents ofthose homes B. What proportion of people who live near high-voltagepower fines [url=]believe[/url] that those fines may cause health problems C. Whether high-voltage power lines[url=]are routed near residential[/url] in urban areas D. What specific diseases or conditions are suspected bysome researchers to result from exposure to magnetic fields from high-voltagepower lines E. What is the[url=]average strength[/url] of magnetic fields in workplaces that are not locatednear high-voltage power lines
A选项，按照lawer大神方法，yes or no，
yes，——not located near的能cause，但是几尺外的磁场比not located near的磁场更弱，不知道到底能不能cause。——削弱
no，——not located near的不能cause 病，几尺外的磁场比not located near的磁场弱，也不能。——加强
