Based on your understanding of the birth rate, death rate, and life expectancy in niger and italy, which of the above sets of graphs is labeled correctly?

Option D --Four (4)

Explanation:

Graph Four(4) makes a very good comparison between two different countries namely: Italy and Niger.

Italy is one of the developed countries in europe while Niger is one of the underdeveloped African countries.

In developed countries people have access to more information and contraceptive methods and family planning, so, there's low birth rate while underdeveloped countries have higher mortality rate. Likewise, due to better economic conditions, developed countries have a longer life expectancy while it's the contrary in underdeveloped countries. These two information has been demonstrated in the Graph 4, where Italy has a higher life expectancy (green column) and lower birth rate (blue column).

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.
