Answer:
Increase; decreasing
Step-by-step explanation:
Grants are specific amounts of money given to entities by government, individuals, organizations for a specific purpose in which the entity given the money doesn't pay back.
Loans are specific amounts of money, properties and the likes given to entities in exchange for future repayment in loan value along with interest.
When there are increases in the loan and grant for college expenses, there would be an increase in the number of graduates. But an increase in the number of graduates reduces the amount available for each graduate, thus decreasing wages paid to college graduates.
