The children and adults participating in stacey's experiment are promised a reward just for participating, but no rewards are given. stacey predicts that the children will be more likely than the adults to express anger when they do not get a reward. this prediction is a(n):

The prediction that Stacey suggested is described as a hypothesis. Hypothesis is being defined as a supposition or proposed explanation by which the person who made such prediction is likely to be based on the basis of limited evidences that we could read in the scenario above.

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.
