A. Reflect actual changes in the nature or organization of work activities in the economy.

Explanation:

The Standard Occupational Classification system is a federal statistical standard used by federal agencies to classify workers into occupational categories for the purpose of collecting, calculating, or disseminating data.

The main function of the SOC is to monitor the work force of a country and provide insightful data such as changes in the structure, skill of the work force nature of the work activities in the economy.

Critically analyzing the other options, we may see that they may not fit into the whole point of the SOC.  

The data gathered and information presented during the Standard Occupational Classification process is completely free of third party interference as suggested by options b and c. hence eliminating them as one of the uses of the system.

The SOC does not really help organizations seek greater recognization for their members. The classification is done by the Federal government , for documentation study and analysis purposes. Organizations cannot use it as a means of advertising themselves.

The SOC does not allow organizations seek a higher profile for their members occupations, as occupations cannot be ranked economically higher than they really are because of personal interest of private parties.

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.
