A – Wrong
The text does not state how interested students from poorer families are in entering university.
B – Wrong
There is no mention of universities not willing to help the government.
C – Correct
The text states that the government is planning to change the policy of grants into loans which will cause the students to repay their debts. The last line of the paragraph says that this action will cause poor students to be deterred from entering university. So C is correct.
D – Wrong
The last line clearly specifies: “students from poorer families”. So D is wrong.
E – Wrong
The paragraph does not say whether grants were too expensive for the government.
