In 1854, the Kansas-Nebraska Act was passed. This law allowed both of these territories to become states. However, before officially becoming a state, the federal government gave them the option to vote on whether Kansas/Nebraska would be a free or slave state. This is what causes "Bleeding Kansas."
Thousands of individuals vote, with the initial results showing that Kansas would be a slave state. However, individuals against slavery, cried foul as citizens from Missouri (a slave state) came over the border and illegally voted in the election. The people who did not want slavery refused to settle on this issue and violence broke out all over Kansas. This fighting between people who did and did not want slavery caused extreme violence and death. This is why it is called "Bleeding Kansas."
The Battle of Midway gave the allies an advantage in the pacific. This is because the US forces there destroyed four aircraft carriers, causing major damage to Japanese naval air forces to the point they couldn’t replace them in time before the war ended.
Here are why the other answers are incorrect:
The island of Midway was actually under US control before the attack, and was too far from Japan for attacks to be held there. However, it was a crucial airbase that had to be kept for control of the local region.
The Japanese took a few more years to surrender, but some historians consider this battle to be a turning point in the pacific campaign.
The majority of carriers were not destroyed at midway, but as stated above, the destruction of four proved to be a crucial victory, since the Japanese couldn’t replace them in a timely manner.
Hope this helps!
