<p dir="ltr"><span><span>Based on the meaning of the context, this question tests a fixed English sentence pattern that is used to say that someone demands that someone else do something. Not only does the verb “demand” fit this sentence pattern, but other verbs that express similar meanings also apply. </span></span></p><p><br></p><div dir="ltr" align="left"><table class="classic-table"><colgroup><col></colgroup><tbody><tr style=""><td><p dir="ltr"><span><span>S + </span><span>command/ order/ require/ request/ ask/ demand/ command/ purpose/ advise/ propose/ insist</span><span> that + S + (should) + the basic form of a verb</span></span></p></td></tr></tbody></table></div><p><br></p><p dir="ltr"><span><span>Thus, (A)</span><span> "is handed"</span><span> and (B) "</span><span>hands"</span><span> should be eliminated since they are not the basic form of a verb.
