Pretend a rattlesnake and a grizzly bear meet in river country. Look at the facts. Then you pick.

Would they meet?

Almost never. Their homes sit next to each other.

This is pretend and based on facts. Real animals usually hide or leave.

THE SCIENCE PICK

Grizzly Bear!

A STOMP

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

On river country, Grizzly Bear wins. Grizzly Bear likes river country more. Rattlesnake 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: Rattlesnake 0 · Grizzly Bear 7 · ties 1.

Your card: Rattlesnake 0 · Grizzly Bear 0.

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