Match the following items. Part A1. best fit curve 2. law 3. control 4. quantitative 5. qualitative 6. hypothesis 7. direct relationship 8. theory Part Ba. general or nonspecific observation b. educated guessc. when two variables change in the same direction, one remaining larger than the other by the same factord. "measured" observation e. standard, reference data, or experiment f. a presently accepted explanation of how something happens g. a statement that explains what something does under the same conditions h. a curve drawn to average the data's deviations

Explanation:

Part A and B match as under  

1. best fit curve  ⇔ a curve drawn to average the data's deviations

2. law ⇔ a statement that explains what something does under the same conditions  

3. control ⇔ standard, reference data, or experiment⇔

4. quantitative⇔ "measured" observation

5. qualitative⇔ general or nonspecific observation

6. hypothesis⇔   educated guess

7. direct relationship ⇔ when two variables change in the same direction, one remaining larger than the other by the same factor

8. theory ⇔   a presently accepted explanation of how something happen

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.
