During the Sixteenth and Seventeenth Centuries in England, the Curriculum

During the sixteenth and seventeenth centuries in England, the curriculum at schools like Trinity College at Cambridge (The College of the Holy and Undivided Trinity) leaned very heavily on theology. Today, the vast majority of university students will never take any theology classes. Why did this change?

A) We have fundamentally changed biologically.
B) Universities in those days were controlled by the state.
C) The Internet has altered social relations to such an extent that education in certain subjects no longer seems important.
D) There are more colleges now, so students who are told they must take theology classes can simply transfer to a different school.
E) The knowledge, values, and expectations required to succeed in contemporary society are different from those required then.
