Given statements: Q > W > X; J > W; Z < X < P Conclusions: I. P > Z → True (as J > W > X > Z & P > X → P > X > Z → P > Z. So, this conclusion is correct.) II. J > Q → False (as J > W > X > Z & Q > W; thus no clear relation between J and Q could be inferred from the given data.) III. W < P → False (as J > W > X > Z; Q > W; P > X; thus clear relation between W and P cannot be determined.) Hence, conclusion I is correct.
