PrepTest 87, Section 3, Question 8
Astronomer: Conditions in our solar system have probably favored the emergence of life more than conditions in most other solar systems of similar age. Any conceivable form of life depends on the presence of adequate amounts of chemical elements heavier than hydrogen and helium, and our sun has an unusually high abundance of these heavier elements for its age.
