The correct answer to this open question is the following.
Although there are no options attached we can say the following.
Slavery continued to spread after the Revolutionary War because southern landlords needed slaves to continue the production of crops. These slaves worked for long hours in the southern plantations under risky conditions. Indeed, the southern economy depended so much on slaves.
The drafting of the Constitution reflected a growing divide between Northern and Southern states on the question of slavery in that slaves were considered or be counted as three-fifths of a person.
Although framers such as George Washington and Thomas Jefferson -who, by the way, owned slaves- opposed the institution of slavery, delegates during the Constitutional Convention of 1787 in Philadelphia Pennsylvania agreed on establishing a limit to allow slavery in the United States until 1808. This created more tense moments and divided the nation.

Officially on the third of October, 1990, East Germany reunited with West Germany. There was a significant amount of apprehension from the perspective of social welfare. The East was known to have a lower standard of living, including less access to goods, products, services and a balanced diet. In addition, education and work opportunities were lower prior to the time of reunification. The industrialized West, had concerns over the ability of the East to quickly improve and reform much of the basic infrastructure in order to get in line with the West's standards.
Over time, the East greatly improved and adopted the same standards for living, including improved roadways, education, products and services. The standards are on par with much of the rest of the country now. In addition, the system effectively integrated much of what was once thought to be only a drain on the West's financial and industrial systems. And of course, Berlin has resumed being the capital. In fact, much of what is done and said in Germany today, is considered the guiding parameters for continued growth and development in the Eurozone block. The European Union relies on Germany's status as an economic power house, clearly demonstrating some of the positive effects that have resulted from reunification.
