Answer:last year
Step-by-step explanation:

This year it was used for 32 wedding receptions and 45 anniversary parties. Therefore, the ratio of wedding receptions to anniversary parties this year is 32/45 = 0.71
Therefore last year, the event hall used for a higher ratio of wedding receptions to anniversary parties.
