Suppose you are buying a car. How would the trade-offs disscussed above affect your decision?

When purchasing a vehicle it is important to weigh out your decisions prior to your purchase. Safety is very important but it comes with a price. For example if you want airbags and anti-lock brakes you will need to buy a newer vehicle and that will cost you more money. If you want to drive a larger SUV that will protect you more because of its size you will be paying more for gas. It all comes down to a person's views on safety and personal freedoms...and of course cost of the vehicle. For me it will always boil down to cost and efficiency of the vehicle.

Explanation:

I did the homework in class and got it correct.

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.
