The fertility rate in a low-income country tends to be more than twice that in a high-income country, and the mortality rate in a low-income country tends to be twenty times higher than that in a high-income country. Given the higher fertility (birth) rate in a low-income country, one major factor that might explain the dramatically higher mortality rate would be that .

High Population

Explanation:

The low incomes countries tend to have high fertility rate which leads to high number of populations. The low income countries are low earners and cannot be able to properly feed there families and provide basic amenities like health care and good water supply which leads to the death of the citizens, and this gives rise to high mortality rate in the low income earners country.

the lack of adequate medical and health resources in a low-income country is far greater than in high-income countries.

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.
