Four rivers have different lengths. River P is longer than River Q. River R is shorter than River Q. River S is longer than River P. Which river is the shortest ?
River R
Comparison statements can be chained into a single order from longest to shortest when every item is linked to another.
Step 1 — P is longer than Q: P > Q. R is shorter than Q: Q > R. S is longer than P: S > P.
Step 2 — Chaining the three statements gives S > P > Q > R, a complete and unique ordering of all four rivers.
Step 3 — River R is at the bottom of the order, so it is the shortest. River S is the longest, while River P and River Q lie in between; none of them is the shortest, so they and the remaining choice do not apply.
River R option is correct.
