c. 26-34
d. 35+

According to the National Household Survey on Drug Abuse, the age cohort reporting the highest lifetime use of marijuana was 18-25 years of age.

Option B

Explanation:

The survey on drug abuse states that the adults in the age 18-25 are more stressed as compared to other adults as well as teens. This is the age where there is maximum peer pressure as well as parental pressure. The adults in the age group of 18-25 need to make important decisions in life like where to go for higher education, which job to apply for and other decisions related to relationships etc. This is the age when most adults are not able to take the stress and pressure and therefore resort to taking drugs like marijuana which provides relaxation to the mind.

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.
