The U.S. Constitution provides that Congress shall have the power to "borrow money on the credit of the United States". Congress has exercised that power by authorizing Federal Reserve Banks to issue Federal Reserve Notes. Those notes are "obligations of the United States" and "shall be redeemed in lawful money on demand at the Treasury Department of the United States, in the city of Washington, District of Columbia, or at any Federal Reserve bank". Federal Reserve Notes are designated by law as "legal tender" for the payment of debts. Congress has also authorized the issuance of more than 10 other types of banknotes, including the United States Note and the Federal Reserve Bank Note. The Federal Reserve Note is the only type that remains in circulation since the 1970s.
If it is possible to answer this question, answer it for me (else, reply "unanswerable"): Where, other than Congress can notes be redeemed?
Ah, so.. unanswerable

Unwilling to accept and license Columbia's system, in February 1949 RCA Victor, in cooperation of its parent, the Radio Corporation of America, released the first 45 rpm single, 7 inches in diameter with a large center hole. The 45 rpm player included a changing mechanism that allowed multiple disks to be stacked, much as a conventional changer handled 78s. The short playing time of a single 45 rpm side meant that long works, such as symphonies, had to be released on multiple 45s instead of a single LP, but RCA claimed that the new high-speed changer rendered side breaks so brief as to be inaudible or inconsequential. Early 45 rpm records were made from either vinyl or polystyrene. They had a playing time of eight minutes.
If it is possible to answer this question, answer it for me (else, reply "unanswerable"): What did RCA release to complete against Columbia's LP?
Ah, so.. The 45 rpm player

Some NPOs may also be a charity or service organization; they may be organized as a profit corporation or as a trust, a cooperative, or they exist informally. A very similar type of organization termed a supporting organization operates like a foundation, but they are more complicated to administer, hold more favorable tax status and are restricted in the public charities they support. Their mole is not to be successful in terms of wealth, but in terms of giving value to the groups of people they administer to.
If it is possible to answer this question, answer it for me (else, reply "unanswerable"): How are groups that focus on financial success organized?
Ah, so..
