THE SCIENCE PICK

Hippo!

A CLEAR PICK

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

On river country, Hippo wins. Hippo likes river country more. Walrus 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: Walrus 0 · Hippo 7 · ties 1.

Your card: Walrus 0 · Hippo 0.

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