P, Q, R, S, T, and U are six giraffes in a jungle, each with a different height. S is taller than Q. P is taller than R. S is shorter than T. Q is taller than P but shorter than T. T is shorter than U. Which of the six giraffes is the shortest?

Explanation

Let’s analyze the given information step-by-step to determine the order of heights from shortest to tallest. S is taller than Q. This means Q is shorter than S. P is taller than R. This means R is shorter than P. S is shorter than T. This places T taller than S. Q is taller than P but shorter than T. This places Q between P and T in height. T is shorter than U. This means U is the tallest among the six giraffes. Arranging the Information From the clues, we can arrange the giraffes in order from shortest to tallest: Since R is shorter than P, and Q is taller than P, R must be the shortest. Then we have P, who is shorter than Q but taller than R. Q is taller than P but shorter than S, so the order so far is R < P < Q < S. S is shorter than T, so T is next: R < P < Q < S < T. Finally, T is shorter than U, so U is the tallest. The final order from shortest to tallest is: R < P < Q < S < T < U. Answer: The shortest giraffe is R.
