) as small as reasonably possible.
B) makes (1 −
) as large as reasonably possible.
C) makes (1 −
) as close to .5 as reasonably possible.
D) makes (1 −
) as close to .25 as reasonably possible.
E) makes (1 −
) as large as reasonably possible and makes
(1 −
) as close to .25 as reasonably possible.
