Answer:
The right answer is A) Literacy tests were banned and federal enforcement powers strengthened.
Explanation:
The Voting Rights Act of 1965 intended to eliminate barriers erected in southern states that impeded African-Americans from voting, a violation of the 15th Amendment. One common obstacle used to block black people was to make them pass literacy tests. This population had lived for centuries in opression, poverty and lack of education opportunities. That was a repugnant racist trick to make ineffective the rights of a good part of American society.
The economy has been extremely stable since the recession ended ten years ago. By historical standards, the volatility of quarter-to-quarter changes in GDP is unusually low. This seems to be a repeat of the Great Moderation.
Here’s a description from my past article on the Great Moderation: “Think back to December 1982 and visualize a business leader with 25 years of experience. That executive had managed through five recessions. Now fast forward to December 2007 and visualize the next generation business leader. In that person's 25 years of experience, he or she had managed through only two recessions. Five recessions or two recessions over the course of 25 years: it makes a difference to how one perceives the world.”
The economy has ups and downs, frequently called business cycles, although the word “cycle” often connotes a regularity that the economy lacks. The volatility has calmed in the last 70 years compared to the era before World War II. It has calmed in two different ways. The frequency of recessions has dropped, and the incidence of unusually strong growth periods has dropped.
Not only were the last 70 years calm, the years from 1983 through 2007 were especially calm. So calm, in fact, that economists dubbed the era “The Great Moderation.”
Then the 2008-09 recession clobbered the economy, and economists declared the Great Moderation over. Since then, however, calm has returned. One economist said “the Great Moderation never really left. It just…treated itself to a two-year vacation.”

Answer:
Tropical rain forest has been most affected by human actions throughout history.
Explanation:
Human actions and inaction have had a devastating effect on the ecosystem. Human actions like deforestation, combustion of fossil fuels, bush burning, use of deadly fertilizers, herbicides and insecticides, etc, had all affected the ecosystem and led to increased depletion of the Ozone layers, thus leading to global warming. These human activities have affected water, food and energy production over the years. They have resulted in environmental degradation and reduced the soil quality. Of all the forests affected by the effect of these human action, the tropical rain forest, which is notable for abundance of rainfall, wildlife and vegetation appears to be the most affected by these human actions. Global warming has led to climate change, and has thus affected global rainfall.
