secularization, history homework help

This research was done by one of studypool’s tutors, I submitted the paper but professor was kind enough to give a feedback what should be fixed so I can get a higher grade. 

Professor’s comment:

Essay is short of the required five pages which can easily be addressed by expanding som on topics. You could go into more detail on the mission system. You mention neophytes in the second part of the essay, they could be addressed in the first part and should be defined. More on secularization. You mention Portola but don’t discuss who he was. More on secularization. How is the mission used today? 

I’m attaching the research paper.
