The correct answer is: A. Only assumption I is implicit
Fascism and communism are both political systems that restrict the rights of the individual. In fascism, the government has complete control over the economy and society, and individual rights are often ignored. In communism, the government owns all property and resources, and individual rights are also often ignored.
The statement “Neither fascism nor communism has any chance of succeeding in America” suggests that the American people are strongly in favor of preserving the rights of the individual. This is because fascism and communism both restrict individual rights, and the American people are unlikely to support a political system that does not respect their rights.
The statement does not suggest anything about whether or not Americans have suffered any pangs of poverty or deprivation. Therefore, assumption II is not implicit.
In conclusion, only assumption I is implicit in the statement.
