Who were 5 important African Americans people/ groups in ww1?
Alisiya [41]

Answer:

The feudal states were not contiguous but rather were scattered at strategic locations surrounded by potentially dangerous and hostile lands. The fortified city of the feudal lord was often the only area that he controlled directly; the state and the city were therefore identical, both being guo, a combination of city wall and weapons. Satellite cities were established at convenient distances from the main city in order to expand the territory under control. Each feudal state consisted of an alliance of the Zhou, the Shang, and the local population.

Which consequence did marchers experience?
Talja [164]
Police violence should be the best answer. There are all types of marchers, marching for different things. There would only be a lack of support from other citizens if those marches weren’t agreed with by the majority, basically saying that some marches had support from others. A repeal of voting legislation is definitely not the answer, as a march is not enough to strip someone’s voting rights away, no matter what time period we’re speaking of. A lack of nation television coverage could be a near answer, as some marches may be seen unimportant and therefore not being televised. But as the question directs to marchers experiences, and not a certain march, this wouldn’t be right. By using order of elimination, the only available, and reasonable answer would be police violence, as many marches are seen as public disorder, and therefore treated by the law. Most of the time, these marches are made to disrupt, and polices mostly respond with brutality or brute.

How did shifting workforce demographics contribute to the dramatic changes that occurred in the US labor force and industry duri
Airida [17]

 Thesis:<span> The US labor force changed greatly toward a job market mostly made of women during the second world war, but then greatly changed back to a male-dominated labor force just shortly after the second world war.</span> 

At the start of World War II, women made on like a quarter of the workforce, as most had to stay home to continue tending their children and maintaining their home.<span> Even though many people kept from having children because of the Great Depression not just recently passing, and many people still couldn't afford maintaining a family, many women still stayed at home instead of signing up in the war because they felt that was the way things should be.</span>
