Answer 1

The response that best supports the evidence that an asteroid collision may have caused the extinction of dinosaurs is:

Rare metal on Earth called Iridium is found in layers where dinosaurs disappeared.

This is because the discovery of iridium, which is more common in asteroids than on Earth, in the geological layer corresponding to the time of the dinosaurs' extinction provides strong evidence for the asteroid impact hypothesis.
