73.The British Admiralty and the War Office met in March 1892 to consider a possible Russian attempt to seize Constantinople and how they would have to act militarily to deal with them.
(A) how they would have to act militarily to deal with them
(B) how to deal with them if military action would be necessary
(C) what would be necessary militarily for dealing with such an event
(D) what military action would be necessary in order to deal with such an event
(E) the necessity of what kind of military action in order to take for dealing with it
不懂為什麼畫線部份不能解釋為:The British Admiralty and War Office當主詞,how "they"的they就有先行詞可代,句意解釋成"他們要如何在軍事上行動及處理..."?
謝謝大家
