Explanation

Start with the last blank because it is the easiest. The clue tells you that the plaintiff’s case disintegrated. Therefore, the claims must have been shown to be false. Facetious, though somewhat negative, does not mean false but does not go far enough. Unerring goes in the
opposite direction. Specious is the best match. The first blank is the easiest one to attempt next. The case fell apart when something happened to the witnesses’ credentials, so a goodphrase for the first blank—which described the role of the witnesses in the plaintiff’s case—is “based on.” Dependent on is the only match.

If the plaintiff’s claims were based on the witnesses, and the case fell apart, logically the witnesses must have been discredited somehow.

A good word for the second blank—which describes what the court decided about the witnesses’ credentials—is denied. Vindicated goes in the opposite direction. Repudiated is the best match.

Hence options C, E and I are correct!
