Question

I think its D? What enabled the United States to become involved in the construction of the Panama Canal?

The government that started building the canal was overthrown by pro-U.S. rebels.
The company that owned the rights to the Canal Zone sold the rights to the highest bidder.
The government that controlled the Canal Zone requested financing from the United States.
The company that was originally constructing the canal could not afford to finish the project.

Answer 1

Considered one of the wonders of the modern world, the Panama Canal opened for business 100 years ago this Friday, linking the Atlantic and Pacific Oceans and providing a new route for international trade and military transport.
At the time it was built, the canal was an engineering marvel, relying on a series of locks that lift ships – and their thousands of pounds of cargo – above mountains.

But thousands of workers died during its construction, and its history has seen no shortage of controversy, including a contentious transference of authority from the US to Panama in the 1970s.

Work recently began on a substantial expansion effort that will allow the canal to accommodate modern cargo needs.

PBS NewsHour recently interviewed several regional experts to discuss the canal’s first 100 years, and to get a sense of what’s ahead.
