reason rocks are interesting.
pursuit of a career in geology.
importance of learning geology.
impact of a good science education.

I think it's C. The importance of learning geology. for example; if I were to talk about the importance of architecture it would only be important to me and  it's design is interesting to me. Architecture would be the main topic of my personal summary, not how interesting the little things are about the topic. Hope this helps :)

c hope this you
