Answer 1

To determine the age of rock #4, you should use Uranium-238 instead of Carbon-14.

Uranium-238 is suitable for dating very old rocks because it has a half-life of about 4.5 billion years, making it effective for dating geological materials that are millions to billions of years old. In contrast, Carbon-14 has a half-life of about 5,730 years, which makes it useful primarily for dating relatively recent organic materials (up to about 50,000 years old). Therefore, for a rock that is 700-750 million years old, Carbon-14 would not be appropriate.

The correct response would be: "700-750 Million Years; Uranium-238; because rock is non-living."
