Definition: In this task you will be given a passage and a yes/no question based on the passage. You should answer the question using the information from the passage.
Input: passage: Today, like the currency of most nations, the dollar is fiat money, unbacked by any physical asset. A holder of a federal reserve note has no right to demand an asset such as gold or silver from the government in exchange for a note. Consequently, some proponents of the intrinsic theory of value believe that the near-zero marginal cost of production of the current fiat dollar detracts from its attractiveness as a medium of exchange and store of value because a fiat currency without a marginal cost of production is easier to debase via overproduction and the subsequent inflation of the money supply.
 question: is the united states currency backed by gold?

No
