Which statement below best describes the political party changes of the mid-1800s? A. a new Whig party formed
B. The republican party grew
C. The democrat party grew
D. Most of the United States supported slavery

The correct answer is B. The republican party grew.

Explanation

During the mid-nineteenth century, the policy of the United States was changed because during this time it was the end of the Civil War in which the Union achieved victory on April 9, 1865, over the Confederation. This meant including changes in the laws including three amendments to guarantee the freedom of the nearly four million African Americans who had been slaves, making them citizens and giving them the right to vote. This had consequences because the Democrats party's supporters were mainly in the Southern States (Confederate), and they had to accept the measures that the Republican majority congress imposed to reunify the country. Therefore, the Democratic party could not participate in some elections while the Republican Party was strengthened. So the correct answer is B. The republican party grew.

world war i began in 1914, after the assassination of archduke franz ferdinand, and lasted until 1918. during the conflict, germany, austria-hungary, bulgaria and the ottoman empire (the central powers) fought against great britain, france, russia, italy, romania, japan and the united states (the allied powers). to new military technologies and the horrors of trench warfare, world war i saw unprecedented levels of carnage and destruction. by the time the war was over and the allied powers claimed victory, more than 16 million people—soldiers and civilians alike—were dead.

explanation:

                the united states presidential election of 1912 was the 32nd quadrennial presidential election, held on tuesday, november 5, 1912. the election was a rare four-way contest.

                incumbent president william howard taft was renominated by the republican party with the support of its conservative wing. after former president theodore roosevelt failed to receive the republican nomination, he called his own convention and created the progressive party (nicknamed the "bull moose party"). it nominated roosevelt and ran candidates for other offices in major states. democrat woodrow wilson was finally nominated on the 46th ballot of a contentious convention, to the support of william jennings bryan, the three-time democratic presidential candidate who still had a large and loyal following in 1912. eugene v. debs, running for a fourth time, was the nominee of the socialist party of america.

                wilson won the election, gaining a large majority in the electoral college and winning 42% of the popular vote, while roosevelt won 27%, taft 23% and debs 6%. wilson became the only elected president from the democratic party between 1892 and 1932, and the second of only two democrats to be elected president between 1860 and 1932. this was the last election in which a candidate who was not a republican or democrat came second in either the popular vote or the electoral college, and the first election in which all 48 states of the contiguous united states participated.
