Piaget proposed that the active construction of reality takes place through the use of schemes. schemes are:

Assimilation and accommodation are the two progressions involved in the use of schemes.  Assimilation occurs when new info is altered to fit a remaining scheme while accommodation involves changing the scheme to adapt to the new information. Schemes Piaget proposed that the active construction of reality takes place through the use of schemes. 

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.
