even though you have attached neither the chart nor the generalizations, i have located them online. the right answer is d, since they are asking you about a generalization. you can only infer from the chart that between 2008 and 2009 the number of employed workers decreased significantly (from over 115 millions to 107 millions approximately), which signals some type of economic crisis.  

in the united states a public policy is an agreed upon way that our federal, state, or local government fulfills its responsibilities, such as protecting the rights of individuals and promoting the welfare of all the people. some public policies are written into laws by legislatures. other policies are contained in rules and regulations created by executive branches of government, the branches responsible for carrying out and enforcing laws.

the following are examples of public policies and the governmental agencies responsible for carrying them out.

school districts are responsible for making policies regarding student behavior and discipline. teachers and school administrators enforce these policies. state legislatures are responsible for making laws that place speed limits on drivers. police officers enforce these laws. city governments often adopt policies that prohibit people from operating liquor stores near public schools. city inspectors and zoning departments enforce these policies.

existing policies or laws that do not work well,

to be able to participate effectively, however, citizens need to know which levels of government and which governmental agencies are responsible for changing, enforcing, or developing a specific public policy. for example, state legislatures may direct agencies to enact policies resulting from federal legislation. or, local governments may create policies in order to carry out responsibilities assigned to them through laws enacted at the state or federal level. additionally, as part of the process of developing and implementing policy, governmental agencies must determine if the new policy conflicts with existing legislation or policy.

this project is intended to you learn how to express your opinions, how to decide which level of government and which agency is most appropriate for dealing with the problem you identify, and how to influence policy decisions at that level of government. it calls for you to work cooperatively with others in your class and, with the of your teacher and adult volunteers, to accomplish the following tas
