Richard Nixon was the 37th President of the United States from 1969 to 1974 and he was very well known for the Water Gate s Scandal which eventually got him impeached and he had to resign as US president.
Choices C he imposed two types of wage control and D he ended the gold standard, are the correct choices. Richard Nixon very nearly destroyed the US economy. In what was them a very small case of inflation, which he tried to correct it by imposing two types of damaging wage price controls, without caring about American free market economy. The consequences of this move were extremely negative for the US economy, because it produced a Stagflation situation that lasted for 10 years.
At the same time, getting the US out of the Gold Standard which connected the value of the dollar to gold, was even more negative than the previous measure. Terminating the gold standard, allowed the US to print more money which was not backed by any gold reserves, to solve a present economic liquidity problem. This in terms, made the dollar lose value for many years to come and create more economic problems.
