单项选择题


I doubt that any historically valid treatment of that presidential administration can emerge for at least another decade, if then. I confess that when I came out of the White House I signed up to do an "insider volume", but sober, professional second thoughts have led me to put that project on ice until at least 1980. The problem is that I simultaneously know too much, and not enough. I know what I thought was happening. But I cannot fully document what happened. And I have seen enough highly classified documents to know that most of what the observers thought was happening was at best half right, at worst dead wrong. This has steered me in a different direction as far as writing is concerned. I am now preparing what is frankly and unashamedly an ex parte memoir, "My Experiences in Washington." It is based on what I believed to be true, on the picture as I conceptualized it, of the presidential administration under which I worked.
The speaker’s experience in reading classified documents made him realize that ______.

A.others had been mistaken in interpreting events that they had observed
B.others knew more about current events than he did
C.he was the only responsible person who knew the truth about government affairs
D.he was a more impartial observer than anyone else in the government
