Without the ability to read ancient Chinese and Maya text, we would be limited to archeological findings and guesses made based on them. The fact, that we can read ancient texts, let us know for example:
the names and times of rule of many rulers,
the religious practices
some events from the past
some cultural and technological inventions such as their knowledge of astronomy
the social composition of the society
Our knowledge of urban live comes from the description of customs and occational information about who lived where and how much was paid for what services
England was the dominant commercial power in the Atlantic ocean in the mid-1700s. During this period, the English society contained a flourishing and more broad middling sector than any other western country. This provided a sturdy opportunity for commerce with, and settlement in, far-flung territories.
All of the aforementioned were designed to help the Allied powers during World War II. Even though the US wanted to stay "neutral" when World War II broke out, they did want to benefit by maintaining economic relationships with these countries.
The Lend-Lease Act is a perfect example. This allowed the US government to lend weapons and other materials to nations like France, Great Britain, and China during World War II. If the goods weapons/materials were destroyed, it was on the country using them to replace it.
The Cash and Carry policy was another example of the US government helping the Allied powers. This policy stated that countries may buy materials from the US, as long as they pay in cash and provide transportation for the materials at their own risk.
Both of these show that even though the US was not technically in the war yet, they heavily favored the Allied powers.
