1. What observational consequences would we find in H-R diagrams for star clusters as a result of the universe having a finite age? Could we use these consequences to establish constraints on the possible age of the universe? Explain.

2. Discuss the possibility of life-forms and biological processes occuring in giant molecular clouds. In what ways might conditions favor or hinder biological evolution?
