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.
Yes, in general this is a true statement, since most of these important changes in technology occurred during the Industrial Revolution, which led to demand for far more resources from areas like South America, which previously did not export a great deal of materials.
Think of the problem this way:
$26.50 = 100% of the original price + 6% of the original price (sales tax)
Now, we have this information.
$26.50 = 106% of the original price.
There is no way you can just get 106% to 100%. So, we're going to find 1% of the original price, then multiply by 100.
And since $265 = 1060% of the original price:
$53 = 212% of the original price
53/212 = $1/4
$0.25 = 1% of the original price
$25 = 100% of the original price
Your answer is $25.
The answer is definitely A, the plague left Great Britain more powerful than any other country because the plague did not spread to there.
