Explanation:
Long time ago, it was common for the early humans to travel from one place to another in a group. They did this in order to follow their food supply. In order to catch their food, they started making tools. Then, they discovered to use fire and so they started to eat food by cooking them first. It also kept them warm. So, this was how they adapted to their early environment.
However, they soon realized that <em>they could control their food supply by planting and raising animals.</em> So, this allowed them to<u> stay in one place. </u>This started the development of agriculture in the world.

Part A: Working hours changed from around 14 hours a day before the 1880's to being reduced slowly down to 12, then 10, eventually moving to an 8 hour day. This change allowed for workers to to have more time to sleep and for leisure. Another change was the end of child labor. Similar to the decrease in hours, the minimum age increased over time as well moving from 10 to 16.
Part B: One strategy used by unions to achieve these goals were strikes. Workers would leave the job and picket outside of a job which shut down operations. This tactic did not work at first because there were plenty of workers to fill the jobs. However, when immigration slowed the tactic had more impact with no people to fill the jobs. Some strikes were so large they brought the attention of police forces and the government.
