Question

Which statement highlights the difficulties faced by those working on the Panama Canal?

Workers had to clear and level mountains so that the entire length of the canal would be at sea level.

The treaty allowed only Americans and Panamanians to work at the site, resulting in a severe worker shortage.

Workers had to dig out tons of earth in rugged, jungle-filled terrain under hot, tropical conditions.

Because there were no railroads in Panama, railroads had to be built first in order to move workers and equipment to the site.
