Understanding the argument -
Historian: The central claim of the “end-of-history” theory is that history has reached its final stage of development. - Background info and claim of someone.
According to its adherents, democratic ideals have triumphed over their rivals, and history is effectively at an ideological end. - Opinion.
But, this view fails to consider that it is impossible to stand outside history to judge whether history is at an end. - Historian's view expressed by contrast. He shares that it's impossible to stand outside all of history and tell whether history has reached an ideological end. Meaning we'll not be able to conclude whether the theory is true.
Which one of the following can be most reasonably inferred from the historian’s statements?
(A) We can never know whether the end-of-history theory is true. - ok.
(B) Advocates of the end-of-history theory have too ideological an understanding of history. - The historian doesn't accuse the advocates of having too ideological an understanding of history. He points out that we'll never know whether this theory is true.
(C) If we were at the end of history, we would automatically know whether the end-of-history theory is true. - No such sufficient condition is implied. Wrong.
(D) It is impossible for the end-of-history theory to be true. - It may be true or not. We don't know, but for now, we know that it's impossible to validate the theory.
(E) Ideological developments are the essential elements of history. - Not implied. Distortion.
