If the central bank wants to expand aggregate de- mand, it can the money supply, which would the interest rate.

The correct answers that fills the gap are: increase, decrease

Explanation:

The aggregate demand is, therefore, the total expenditure that families, businesses, the public sector and foreigners make for an individual price level. On the other hand, the graphical representation of aggregate demand is known as the aggregate demand curve and shows the different quantities of product that economic agents are willing to acquire at each price level.

As with individual demand, aggregate demand increases as prices drop, and vice versa. On the other hand, by increasing the average price level, aggregate demand will decrease, since the amount of goods and services that can be acquired with the same money is reduced.

As we can see, prices are the main variable that determines what economic agents demand, although not the only one. Other conditioning factors are the amount of money circulating in the economy, the taxes established by the public sector or the level of income of economic agents.
