Answer:
If someone refused to answer questions asked by the House Un-American Activities Committee, he could be accused of being a communist.
Explanation:
The House Un-American Activities Committee was active between 1934 and 1975. This committee, whose activities accelerated especially in the 1950s, investigated many American artists and intellectuals. In 1969, the name of the Committee was changed to "House Committee on Internal Security", and in 1975 it was ceased.
Many prominent artists such as Albert Einstein, Hanns Eisler, Orson Welles and Jules Dassin were investigated, suspected on being communists, or even worse, Soviet spies.
You didn't list options, but I'll suggest an item which famously occurred during Warren G. Harding's presidency:
<h2>The Teapot Dome Scandal</h2>
This was a scandal in which one of President Harding's cabinet members illegally leased oil reserves. President Harding was not directly implicated in the scandal, but was affected by it. After President Harding transferred supervision of the naval oil-reserve lands from the navy to the Department of the Interior in 1921, Secretary of the Interior Albert Bacon Fall secretly gave Harry Sinclair of the Mammoth Oil Company exclusive rights to the Teapot Dome reserves in Wyoming. He granted a similar deal to another oil company executive. The secret leases came under Congressional investigation. Congress directed President Harding to cancel the leases, and the Supreme Court ruled that Harding's transfer of authority to Interior Secretary Fall had been illegal. The whole affair took a toll on President Harding's health. He died in office in 1923.
The most correct answer here would be are D - tribal and religious groups.
Tribal and religious groups are a serious obstacle in the middle east which disabled the probability of achieving a stable and democratic government in any short period to be seen.
