Question

president nixons action to end the gold standard
created a budget deficit.
meant gold was no longer valuable.
meant the value of the dollar changed.
ended the us economic downturn.

Explanation:

In 1971, Nixon ended the gold standard, which tied the U.S. dollar's value to a fixed amount of gold. Removing this link meant the dollar's value would now float based on market forces, so its value changed. A budget deficit was not directly caused by this action; gold still held intrinsic value; and the action did not immediately end the U.S. economic downturn.

Answer:

meant the value of the dollar changed.
