In contrast to the monetarists, the keynesians assume that the velocity of money varies directly with

Government expenditures

Explanation:

 The major difference between the monetarist and Keynesian economic theory is that the monetarist argue for the control of money in the economy while the Keynesian economics involve the government expenditures.

Milton Friedman formulated the monetarist economic theory and John Maynard Keynes formulated the Keynesian economics theory.

two jet streams that directly affect the formation of weather in the continental part are a polar jet and a subtropical jet. they are responsible for the transportation of weather systems, which directly affect people. the polar front is the boundary between cold air from the north pole and warmer equatorial air. both the polar jet and the subtropical jet blow from the west to the east, and follow the boundary between cold and warm air.

the strongest jet streams are polar jets, while subtropical jets are somewhat weaker.

the right answer is c. the polar jet stream is generaly stronger than the subtropical jet stream.
