Realpolitik.
.
It's a theory where politics are based on practical matters rather than theory/ethics.
A is wrong, as if you check, John Adams' presidency was from 1797 to 1801--only a single four year term.
B is true. Since George Washington made the Proclomation of Neutrality before him, John Adams ended up having to uphold it. There's a famous debacle called the <em>XYZ </em><em>Affair</em> where US diplomats were stopped from talking to the French foreign minister by his agents unless they paid a hefty bribe. (whose names were replaced with X, Y, and Z when Adams released the documents so as to avoid involvement in French wars)
C is wrong. John Adams' wife, Abigail Adams, had been married to Adams for over thirty <em>years</em> before he took office.
D <em />is wrong. The Louisiana Purchase was in 1803, during which the third president, Thomas Jefferson, was in office.
The correct answer is B) German-American schools, churches, and magazines largely abandoned the use of the German language.
One effect that World War I had on German Americans was that German-American schools, churches, and magazines largely abandoned the use of the German language.
Without a doubt, the German community in the United States suffered from anti-German sentiments during and after World War 1. US citizens started to demand the ban of the German language in the country. This meant no more German-speaking in schools or churches. Many German sites such as theaters were closed. And people also demanded to stop any kind of publication in German, magazine or newspaper.
The executive branch carries out and enforces laws. It includes the president, vice president, the Cabinet, executive departments, independent agencies, and other boards, commissions, and committees.
