In short, nothing (read more, things do definitely happen). The money supply however changes and by extension the money multiplier changes over time. The way that question is presented however is asking about a direct relationship, which there is none. Absolutely there is an indirect result however.
Increasing the reserve ratio effectively reduces the money supply within the banking world. This results reduced loan availability with reduces investment. Lower investment causes a stagnation in industry. A stagnation in industry causes recession (through countless ways). People are laid off and companies are hesitant to explore markets. Net result? Less spending. With less spending people/businesses in this situation worry more about their long term stability and care less about immediate spending needs. Both industry and individual "tighten" their belt so to speak. No more investment, and therefore the banks continue the cycle. The money multiplier changes to reflect the propensity to save across all fronts.
Basically, an increased ratio requirement results in a lower multiplier factor. Not directly, but that's what happens.
On second thought, I should probably give the simple response that you're going to face in a test. Very simple. Fractional banking infrastructure means that increasing the required reserve reduces loan capacity. Reduced loan capacity results in a propagation of less loan potential. This effect permeates through all of society. The result is that money cannot be "created" by banks/enterprises/individuals as much as before by relying on interest. Hence, the multiplier of money goes down because the velocity of money goes down.

Yes b/c this would increase the banker's availability to funds and thus increase the money supply, stimulating the economy.
A decrease in aggregate demand, an increase in the reserve requirement, an increase in the discount rate, increase in interest rates, a decrease in government spending.

If the Federal Reserve decided to increase the reserve requirement in banks, it is likely that banks would be targeted more often for robbery. This would be because there would be more money in every federally-insured bank.
The required reserve ratio is lowered.

Under a fractional reserve banking system, the amount of money loaned out can only increase if there is an increase in the bank's reserves or a rise in customer deposits. This can occur when the central bank injects more liquidity into the banking system, or when banks attract more deposits from customers. Additionally, if banks are able to maintain a lower reserve requirement set by the central bank, they can lend out a greater portion of their deposits, thus increasing the overall money supply.

how can we increase the general reserve
Consumer spending is called consumption, which is a component of Aggregate Demand in our economy. In monetary policy, the Federal Reserve can buy treasuries, lower the reserve requirement, and lower the discount rate which will increase consumption. In fiscal policy, the government can cut taxes to increase consumer spending.
will discourage aggregate demand.
