The result of flipping an evenly weighted, or "fair," coin, a process commonly thought to be random, is, in fact, well determined by the impulse given the coin and by the height above the floor from which the coin starts. Yet it is difficult to predict the result of a fair coin flip.
Which of the following, if true, contributes most to an explanation of why the outcome of a coin flip is difficult to predict even though it is well determined?
(A) Coin flipping has been used as a prime example, of a random process for decades.
(B) The result of flipping an unevenly weighted coin can be predicted with great accuracy.
(C) If the impulses of coin-flipping remain perfectly constant, the results are determined only by the height from which the coin falls.
(D) An accurate prediction of the result of a coin flip requires extraordinarily precise estimation of height and impulse.
(E) That the results of coin-flipping are well determined runs counter to the randomness that physicists have been finding in more and more processes once thought to be determined.

out of scope
(B) The result of flipping an unevenly weighted coin can be predicted with great accuracy.
we are dealing with "fair" coin
(C) If the impulses of coin-flipping remain perfectly constant, the results are determined only by the height from which the coin falls.
impulse and height must be precisely determined
(D) An accurate prediction of the result of a coin flip requires extraordinarily precise estimation of height and impulse.
extraordinarily precise estimation of height and impulse may not be possible and for this reason the outcome can not be predicted
(E) That the results of coin-flipping are well determined runs counter to the randomness that physicists have been finding in more and more processes once thought to be determined.
do not explain why the outcome is difficult to predict

(B) The result of flipping an unevenly weighted coin can be predicted with great accuracy.
again of scope as we're talking about fair coin
(C) If the impulses of coin-flipping remain perfectly constant, the results are determined only by the height from which the coin falls.
irrelevant. doesn't help explaining why it's hard to predict
(D) An accurate prediction of the result of a coin flip requires extraordinarily precise estimation of height and impulse.
seems close enough. Extraordinary precision isn't common
(E) That the results of coin-flipping are well determined runs counter to the randomness that physicists have been finding in more and more processes once thought to be determined.
similarity of randomness with other processes doesn't provide any strong evidence
IMO D
