Which social changes occurred after World War I and prior to World War II?

Answers

World War I brought about tremendous change for African Americans and their place in American society.

The Great Migration transformed the demographics of black communities in the North and the South.

The war effort allowed black men and women to assert their citizenship, hold the government accountable, and protest racial injustice. Military service brought thousands of black men into the army, exposed them to new lands and new people, and allowed them to fight for their country. Black people staked claim to democracy as a highly personal yet deeply political ideal and demanded that the nation live up to its potential.

World War I represents a turning point in African American history, one that shaped the course of the black experience in the twentieth century.

The American colonists viewed the deaths of native Americans due to disease as:

unfortunate

divinely sanctioned opportunities

preventable realities

none of these responses are correct ​

Answers

Answer:

divinely sanctioned opportunities

Explanation:

correct me if I am wrong

[tex]{hope it helps}}[/tex]

The American colonists viewed the deaths of native Americans due to disease as divinely sanctioned opportunities Option(b) is correct. The genuine thought of appeasement is obliterated on the off chance that man doesn't be aware for what he is making amends.

What does divinely sanctioned opportunities denotes?

The term divine sanction is utilized to pass the possibility that man is eventually responsible on to God for his activities here on the planet.

This conviction is principal to a strict perspective on the world. It suggests that man isn't independent yet is under God but simultaneously a free specialist and not the survivor of destiny (see destiny and resignation). It implies that occasions in this life have impacts far rising above the simply transient request.

The idea of remuneration and discipline found among non-Christian people groups communicates this reality, truth be told, insufficiently. The principle of metempsychosis in its different structures is boundless and owes its prevalence to the trouble man encounters in envisioning a sanction that is conclusive and irreversible.

A progression of lives, as propounded by numerous Asian religions and different types of theosophy, considers a prize or discipline of some kind or another yet doesn't consider the proceeded with presence of the human individual.

Therefore Option(b) is correct.

B. He had lost World War II.
C. He did not want to run again.
O D. Southern Democrats were upset he supported civil rights.

Answers

your answer is should be D <3
your welcome

Harry Truman faced a difficult reelection campaign in 1948 due to several reasons, but one of the main factors was the opposition from the Southern Democrats who were upset with Truman's support for civil rights. Hence option D is correct .

Why did Harry Truman face a difficult reelection campaign in 1948?

During his presidency, Truman had taken several actions aimed at addressing racial inequality and discrimination, including desegregating the armed forces and supporting anti-lynching legislation. However, these actions were deeply unpopular among Southern Democrats who were staunchly opposed to racial integration.

In response to Truman's civil rights initiatives, a group of Southern Democrats formed the States' Rights Democratic Party, also known as the Dixiecrats, and nominated South Carolina Governor Strom Thurmond as their presidential candidate. The Dixiecrats ran a campaign focused on defending racial segregation and states' rights, which further divided the Democratic Party and made Truman's reelection campaign even more challenging.

Despite facing significant opposition, Truman managed to win the 1948 election in a stunning upset, largely due to his energetic campaigning and his ability to connect with working-class voters. His victory marked one of the most remarkable comebacks in American political history.

What was not a business practice employed by the titans of industry in the late 1800s?
O building monopolies
O establishing trusts
standardizing production
developing international cartels


Answers

Answer: developing international cartels

Explanation:

The business practices that were employed by the titans of industry in the late 1800s include the building of monopolies, establishing trusts and the standardizing of production.

This led to the growth of the industries. While the owners of the businesses got richer, their employees were bit treated well and they were paid unfairly for the services that they rendered.

It should be noted that developing international cartels wasn't among the practices that they used. Therefore, the correct option is D.

C.
the rise of rock and roll and demise of jazz
D.
dissatisfaction with a segregated society

Answers

Answer:

The correct answer is A. The embrace of machismo by mainstream society.

Explanation:

Machismo refers to a man who behaves overly masculine and displays his courage, physical masculinity, taste for women and aggressiveness. According to the cliché, machos are supporters of the traditional division of roles between men and women. They would take a negative view of a woman's rights to work, participate in sports, or pursue other traditionally masculine roles in society. Regardless of their underlying views, machos certainly stand out because of their imperious behaviour.
