Explanation:
The economic problems faced by the Congress deeply touched the lives of most Americans in the 1780s. The war had disrupted much of the American economy. On the high seas the BRITISH NAVY had great superiority and destroyed most American ships, crippling the flow of trade. On land, where both armies regularly stole from local farms in order to find food, farmers suffered tremendously.
The correct answer would be the third option ''that American Indians worshipped false gods.''
Early navigation relayed on mariner's ability to read the stars, which were not always exact and led to failure, discretion and less disposition to explore.
<em>The Renaissance</em> created an intellectual ambiance that promoted exploration, bringing massive interest in science, ergo scientific methods made navigation more exact and safer while traveling by ship.
Exploration was enabled by the evolution and development of geography, the development of navigational tools such as compasses, accurate maps, sea charts, and the scientific advancement in vessel designs.
Thus "<em>explorers were able to take long and far trips across the ocean </em><em>because of the development of navigational tools"</em><em>.</em>
I believe it would be false because the first organized civilization was Sumer in Mesopotamia. If that where all that was required to be a civilization, then I could create my own! :)
Hope this helps! :)
