Which of the following is NOT the purpose of America’s central bank? [br] [orig

America’s Central Bank is part of a larger financial system called the United States Federal Reserve System. It is not a single bank, but a banking system with operations that are both public and private. Its purpose is to control the flow of money in the economy, to supervise banking activity and to protect the financial system.

Windmills are sprouting across the United States, as Americans search for non-polluting alternative energy sources. However, the industry still has work to convince Americans of the virtues of wind power. Some residents complain that the large towers are unsightly, and environmentalists have criticized the windmills as dangerous to birds. This is more of a problem at another site in Northern California, which is on a migration route. In response to complaints, owners have agreed to a temporary shutdown of some of that area’s wind turbines during this year’s winter migration.
