Which three topics became a major focus of the enlightenment?

I believe the Enlightenment period was also called the Age of Reason.

1. science- tying to understand the natural world and the reason why humanity was on earth without incorporating religion.

2. philosophy- writers who  looked at occurring events and tried to explain the causes of them through reasoning

3. Literature

4. The Arts- music paintings

Hopefully this helps somewhat. The Enlightenment  era was during the 17th and 18th century. I think the easiest way of explaining this era, it's really complex, is that it was an era in which people questioned things such as events, behaviors, or whatever by using science instead of religion.

by 1890, the united states had by far the world's most productive economy. american industry produced twice as much as its closest competitor--britain. but the united states was not a great military or diplomatic power. its army numbered less than 30,000 troops, and its navy had only about 10,000 seamen. britain's army was five times the size of its american counterpart, and its navy was ten times bigger. the united states' military was small because the country was situated between two large oceans and was surrounded by weak or friendly nations. it faced no serious military threats and had little interest in asserting military power overseas.
