People who object to the proposed hazardous waste storage site by appealing to extremely implausible scenarios in which the site fails to contain the waste safely are overlooking the significant risks associated with delays in moving the waste from its present unsafe location. If we wait to remove the waste until we find a site certain to contain it safely, the waste will remain in its current location for many years, since it is currently impossible to guarantee that any site can meet that criterion. Yet keeping the waste at the current location for that long clearly poses unacceptable risks. The statements above, if true, most strongly support which one of the following? ['The waste should be placed in the most secure location that can ever be found.', 'Moving the waste to the proposed site would reduce the threat posed by the waste.', 'Any site to which the waste could be moved will be safer than its present site.', 'Whenever waste must be moved, one should limit the amount of time allotted to locating alternative waste storage sites.']
