We learn that students from outside the province of Markland pay twice as much tuition as students from the province of Markland.
We also learn that students from outside the province of Markland have traditionally accounted for at least 2/3 of the students at Central Markland College. However, over the past 10 years, the proportion of students who are from outside the province of Markland has dropped to about 40%.
This means that the College now has a lower proportion of out-of-province students who pay twice as much tuition as local students.
Therefore, if the College's per capita revenue from tuition has remained the same over the least ten years, then tuition fees must have increased.
This is directly re-stated by answer choice (E), making it the correct answer.
Answer choice (A) is incorrect because the passage does not tell us anything about the relationship between tuition fees and academic standards.
Answer choice (B) is incorrect because we cannot draw this conclusion. Maybe a college opened up outside of Markland that attracted students; maybe the students from outside of Markland could no longer afford the higher tuition fees.
Answer choice (C) is incorrect because we are talking about proportion, not number of students.
Answer choice (D) is incorrect because there is no information provided in the passage to support this claim.
