Continental drift!

Expert replies
by gmat_perfect » Fri Jun 04, 2010 2:40 am
Early in this century, Alfred Wegener developed the concept of continental drift. His ideas were rejected vehemently because he postulated no identifiable force strong enough to make the continents move. We have come to accept Wegener's theory, not because we have pinpointed such a force, but because new instruments have finally allowed continental movement to be confirmed by observation.

The passage best illustrates which one of the following statements about science?

(A) The aim of science is to define the manifold of nature within the terms of a single harmonious theory.
(B) In accepting a mathematical description of nature, science has become far more accurate at identifying underlying forces.
(C) The paradox of science is that every improvement in its measuring instruments seems to make adequate theories harder to work out.
(D) Science, employing statistics and the laws of probability, is concerned not with the single event but with mass behavior.
(E) When the events a theory postulates are detected, the theory is accepted even without an explanation of how those events are brought about.

OA: E
=> I am not convinced with the OA.

E is good

W developed the concept of Continental Drift, but he didnt explain which force caused it, so his theory was rejected. Now, new instruments have confirmed continental drift by observation, so W's theory has been accepted even if there is still no explanantion on what causes continental drift.

E is a paraphrase of the above and hence correct. All others are out of scope and do not follow from the passage
