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 presence of iridium, which is more common in asteroids, in rock layers corresponding to the time of the dinosaurs' extinction is a key piece of evidence supporting the asteroid impact hypothesis.
