Answer:
1: The formation of elements heavier than iron and nickel requires the input of energy. Supernova explosions result when the cores of massive stars have exhausted their fuel supplies and burned everything into iron and nickel. The nuclei with mass heavier than nickel are thought to be formed during these explosions.
Explanation:
2: The more luminous they are, the more reactions are taking place in their cores. Massive stars live shorter lives than the common small stars because even though they have a larger amount of hydrogen for nuclear reactions, their rate of consuming their fuel is very much greater.

Explanation:
Colleges should have no interest in what your parents did, as it isn't necessarily applicable to the path you want to follow. Your employment history is also irrelevant because, again, it's your path. What makes A wrong is that they should have very little interest in your personal life and do not need to know any of your private information (e.g. credit cards, relationships, etcetera). The correct answer is C because you are going to college to pursue a certain career and they must know what it is you want (or plan) to do.
