Scientists attempting to replicate certain controversial results reported by a group of experienced researchers failed to get the same results as those reported. The conclusion drawn from this by the scientists who conducted the replication experiments was that the originally reported results had been due to faulty measurements.

The argument of the scientists who conducted the replication experiments assumes that

(A) the original experiments had not been described in sufficient detail to make an exact replication possible
(B) the fact that the originally reported results aroused controversy made it highly likely that they were in error
(C) the theoretical principles called into question by the originally reported results were themselves based on weak evidence
(D) the replication experiments were not so likely as the original experiments to be marred by faulty measurements
(E) the researchers who originally reported the controversial results had themselves observed those results only once

Answer D
The Conclusion of the argument
scientists who conducted the replication
experiments was that the originally reported results had been due to faulty measurements.
Negation of Option D
the replication experiments were likely as the original experiments to be marred by faulty measurements.
If the replication experiments were marred by faulty measurements then the conclusion falls apart.
Please give me kudos . I need them badly to increase my score.
