Answer:
The infamous "grandfather clauses" of the late 19th and early 20th centuries stated that people who exerted their right to vote prior to 1866, as their descendants, were exempt of certain requerements for voting such as the owning of property, payment of poll taxes and literacy tests.
Explanation:
These clauses existed in many Southern states and were a direct attempt to prevent African-Americans from voting. They were outlawed by the Supreme Court in 1915 that decided they were against the 15th Amendment. Despite this decision African-Americans in some Southern states were able to vote only after the Voting Rights Act of 1965.
The transcontinental railroad made it much easier and faster to bring goods and people across the continental United States. This made shipping easier and cheaper, and commerce increased drastically (Answer is B).
The railroad made many people, namely capitalists, incredibly rich, and very influential in government. Corruption naturally occurred, but it was not so huge as to have a net negative effect on commerce, since the gains brought by the railroad were so great.
The railroad did not make all trading posts disappear. Although some trade posts that were not located on or near the railroad may have become less relevant, a large number of trade posts thrived thanks to the traffic brought by the railroad.
The government wanted to keep the number of free and slave states equal so that neither of would throw off the balance of congress.
For example, if there was more slave states in congress, then most likely the laws would be made in favor of slavery. Or vice versa.
