D would be the most appropriate. C and B would be very bias, especially since C was written by a general in World War II, meaning that it would only be his point of view and not the other argument. D, is by a trustworthy newspaper columnist (since it's popular) who has read both books and written a view on both which would most likely not be very bias.
The McCarthy Era was one of the darkest chapters in American
History. The U.S. government was so
determined to root out Communist threats in their country. Their suspicion was stronger than their
better judgment and as a result, many innocent were unjustly accused of either
being communist spies or sympathizers.
Some lost their careers while others were sentenced unjustly. It is a grim reminder that we should let
paranoia rule our actions. We must also
defend our freedoms against any unlawful arrest without any proof. Our freedom and understanding is far too
important for us to take for granted. That Era nearly took it away from us. We must never let it happen again.
I would say that Plessy v. Ferguson contributed to the Civil Rights movement. This was a court case that ruled that racial segregation in schools was allowed as long as the education for black students was equal to white students. Although this does not seem like a civil rights act, it later lead to Brown v. Board of Education, which ended racial segregation in schools all together.
