Recall that harold kelley (1950) told some college students that their guest lecturer was a warm person, and others that he was a cold person. the visitor then lectured for twenty minutes, and behaved in a very arrogant way during the lecture. when students evaluated the lecturer,

I believe the answer is: students expecting a warm person rated the lecturer as funnier, but no less arrogant than students who expected a cold person.

People who make the assumption that another people is generally kind and warm would be much more likely to interpret the arrogance as an effort to be comical. People who make the assumption that other people is cold on the other hand would see the arrogant behaviour as an affirmation to their initial assumption.

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.
