Who built the panama canal second? did they succeed? why or why not?

France was the first to built the Panama Canal, but had to stop halfway through, so the second country to build the Panama Canal was the United States which took over a decade to finish it. They were very successful as their engineer work in the Panama Canal enabled people trying to go through it to avoid the lengthy and hazardous route called the Cape Horn route around the tip of South America. Instead it was replaced with a faster and safer route which has proved very beneficial so far.

The correct answer is a. when they started making tools that will them in cultivating lands, they could raise crops and that made them attached to one place for a longer period of time. after that, they started domesticating animals and building their own permanent settlements that resemble the ones we have today.
