Answer:
 1 is this: The four middle lines of latitude are the Tropic of Cancer, the Tropic of Capricorn, the International Date Line and the Prime Meridian.
2 is: Climate models project robust differences in regional climate between present-day and global warming up to 1.5°C, and between 1.5°C and 2°C (high confidence), depending on the variable and region in question (high confidence).
3 is: The term civilization refers to complex societies, but the specific definition is contested.
The advent of civilization depended on the ability of some agricultural settlements to consistently produce surplus food, which allowed some people to specialize in non-agricultural work, which in turn allowed for increased production, trade, population, and social stratification.
The first civilizations appeared in locations where the geography was favorable to intensive agriculture.
Governments and states emerged as rulers gained control over larger areas and more resources, often using writing and religion to maintain social hierarchies and consolidate power over larger areas and populations.
Writing allowed for the codification of laws, better methods of record-keeping, and the birth of literature, which fostered the spread of shared cultural practices among larger populations.

World War II took place from 1939 to 1945 and the following events led up to the United States becoming involved in WWII. 
In 1939, the US cancelled its trade agreement with Japan.
The US embargoed (or outlawed the buying or selling) of Japanese iron, steel, and mechanical parts.
Japan sent troops to Indochina to pressure British and Dutch Far East possessions and US, British, and other Western nations reacted by freezing Japanese assets and blocking the buying of Japanese oil. 
Japan and the US were in talks to ensure peace, but ideas put forth by the Japanese were considered to be inadequate by the US. Japan was asked by the US to evacuate China but the Japanese refused to, suggesting they would instead be preparing for a war.
The Japanese bombed/attacked British and American holdings on December 7, 1941 (including Pearl Harbor).
