D. The Espionage and Sedition Acts.
Explanation:
President Woodrow Wilson passed the Espionage and Sedition Acts in 1917. With these acts, it was against the law and was considered a crime to criticize the United States by using abusive and vile language. You also could not interfere with the United States trying to defeat Germany by stating different opinions publicly.
With the United States' involvement in World War I, many did not agree with what was happening. Some people thought that the United States should have just stayed out of it altogether, which resulted in many proving to be disloyal to the United States and its cause.
The Espionage and Sedition Acts made it illegal to say such things about the United States. You could not interfere with the United States relations with Germany by saying certain opinions or saying anything that related to being disloyal to the United States.

Here we go, long story begins: Many serbs believed that Sarajevo belonged to Serbia, but it belonged to Austria-Hungary. When Archduke Franz Ferdinand (Leader of Austria-Hungary) came to visit Sarajevo, a Black Hand member (The Black Hand was a group of Serbs that wanted independence for Sarajevo) threw a grenade at his car, but it missed, killing innocents. Later, the Archduke's driver took a wrong turn, and it passed Gavrilo Princip, another Black Hand member, getting a sandwich. Princip rushed the car, shooting with his pistol, and killing the Archduke and his wife, Sophie. This caused Austria Hungary to declare war on Serbia. Russia declared war on Austria Hungary to protect their fellow slavic nation Serbia. Germany then declared war on Russia. France (who made a secret alliance with Russia) then declared war on Germany. Realizing that Germany had to deal with France first, Germany invaded Belgium to get to France, but Belgium was allied with Britain, causing Britain to declare war on Germany, and then World War I began.

The correct answer is: C) familiarity with and disdain for the northern industrial workplace.
Secession and, therefore, Civil War were mainly about the right to own slaves. Slaves were, for the Southerns, the most important "material" in the workplace; their region relied on slave-owning in order to do agrarian work.
The Northerns, however, now were in their way to industrialization, where the work at factories was done by employed immigrants and, thus, they were all for abolishing slavery.
