Pretend a otter and a koala meet in forest. Look at the facts. Then you pick.

THE SCIENCE PICK

Otter!

A CLEAR PICK

You skipped a final pick. The facts still stamp a champ.

On forest, Otter wins. Otter's needle teeth plus twist helps more. Koala would still win some meetings at home.

In the wild, most animals skip a fight. We still judge who the bodies and the place would favor.

Science card: Otter 6 · Koala 1 · ties 1.

Your card: Otter 0 · Koala 0.

The last page follows the whole animal — body plus home — not one bar chart.
