Ever since Uranus was discovered in 1781, astronomers have thought there might be more planets to be discovered in the Solar System. Because of small deviations in the orbits of Uranus and Neptune - deviations which would occur if another planet existed - some astronomers think there must be an undiscovered planet - Planet X. But the search for Planet X is futile, because these deviations would occur if the orbits had been wrongly predicted. Since Uranus and Neptune take many decades to circle the sun, astronomers must rely on old data in order to calculate their orbits. If this data is inaccurate, the calculated orbits are wrong. If the calculated orbits are wrong, Uranus and Neptune will deviate from them even if there is no Planet X. Which of the following is the best statement of the flaw in the argument above?
A.
From the fact that the old data is inaccurate, it cannot be inferred that the calculated orbits are wrong.
B.
From the fact that the data about the orbits is old it cannot be inferred that it is inaccurate.
C.
From the fact that deviations occur which would occur if Planet X existed, it cannot be inferred that Planet X exists.
D.
From the fact that the calculated orbits are wrong, it cannot be inferred that Uranus and Neptune will deviate from them.
E.
From the fact that Planet X has not been discovered, it cannot be inferred that the search for it is futile.
