Question 1

True or false: The Panama Canal was built at sea level, with no locks needed for most of its length.

Accepted Answer

False. It is a lock-and-lake canal, raising ships 85 feet above sea level via Gatun Lake, not a sea-level canal.

Question 2

True or false: The U.S. gave Panama full control of the canal in 1999 as part of a treaty signed by Jimmy Carter.

Accepted Answer

True. The Torrijos-Carter Treaties (1977) transferred control to Panama on December 31, 1999, ending nearly a century of U.S. control.

Question 3

True or false: The Panama Canal was originally built by the French, who succeeded in completing it.

Accepted Answer

False. The French started the canal in 1881 but failed due to disease and financial issues. The U.S. completed it in 1914.

Question 4

True or false: A ship traveling through the canal pays the same toll no matter how much cargo it carries.

Accepted Answer

False. Tolls are based on ship size, type, and cargo capacity (in TEUs or tons). A small yacht pays far less than a massive container ship.

Question 5

True or false: More workers died building the Panama Canal than during the entire American Civil War.

Accepted Answer

True. Over 25,000 workers died during the French and U.S. efforts, mostly from yellow fever and malaria—exceeding the ~24,000 Civil War combat deaths on the Union side.

Question 6

True or false: Mosquito control was the key innovation that allowed the canal to be finished after the French failed.

Accepted Answer

True. Dr. William Gorgas’s mosquito eradication program drastically reduced yellow fever and malaria, enabling the U.S. to succeed where the French failed due to disease.

Question 7

True or false: The Panama Canal uses freshwater, not seawater, to move ships through its locks.

Accepted Answer

True. Each lock chamber is filled with freshwater from Gatun Lake, not seawater, to prevent mixing saltwater ecosystems and reduce lock corrosion.

Question 8

True or false: The Panama Canal cut the sea voyage from New York to San Francisco by over 12,000 miles.

Accepted Answer

False. It actually cut about 7,800 miles off the trip around Cape Horn—still huge, but not over 12,000.
