138. Senator Lasker has proposed legislation requiring that employers should retain all older workers indefinitely or show just cause for dismissal.
(A) that employers should retain all older workers
(B) that all older workers be retained by employers
(C) the retaining by employers of all older workers
(D) employers' retention of all older workers
(E) employers to retain all older workers
in B, the awkward shift to the passive construction makes workers the subject of show, thus producing the unintended statement that older workers [rather than employers] are required to show just cause for dismissal.
=> I don't know what that means. Someone can interpret for me.
