Explanation:

The Moving to Opportunity study found that those in the group who received assistance in relocating and life-skills training in addition to housing vouchers experienced less stress and better health.

The Housing and Urban Development (HUD) of the United States of America sponsored the unique random experimental research in 1982 among a total of 4,600 low-income families with children living in high-poverty public housing projects in five (5) participating cities, Baltimore, New York City, Los Angeles, Chicago and Boston. This families were mainly headed by a Hispanic or African-American single mums.

These families who participated were divided into three (3) research groups by lottery;

1. Traditional voucher groups: didn't receive counseling but got vouchers that could be used anywhere.

2. Low poverty voucher groups: received counseling in finding private units to lease and vouchers that could only be used in low poverty areas

3. Control groups: were eligible for public housing projects or programs but didn't receive any voucher.

After the study, it was observed that those in the low poverty voucher groups experienced less stress and better health.

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.
