The three biggest problems were rain, disease, and transportation.
The rain, particularly during the wet season, would cause mud slides and make the ground very dangerous. Weeks of work were often wasted every time a mud slide filled in areas previously dug out. This was most evident in the Culebra Cut. The cut was an artificial valley, not too far from Panama City, that had to be dug two feet wide for every foot deep. It was considered one of the biggest engineering feats of the time. The cut was an early adopter of terracing for that reason.
Diseases such as malaria, yellow fever, cholera, and dengue fever were transmitted by mosquitos. While the French were building the canal, disease took a massive hit on the labor, killing thousands of able-bodied men. It was a long time before officials realized that standing water was attracting the mosquitoes. When the Americans took over the project, they made an enormous effort to remove all bodies of water from the cities. Hospital bed posts were submersed in water to prevent termites. People kept barrels for water outside their homes. All of that water had to be covered or removed. They were able to get the diseases under control, but it’d be a long time before cures and pesticide efforts were put in place. Panama still employs trucks that spray for mosquitoes regularly.
The third problem was the transportation of men, supplies, and the soil as it was being removed. The construction of a railway greatly helped by hauling millions of tons of men, equipment, and supplies, but more importantly hauled the hundreds of millions of cubic yards of material removed from the canal cuts.
I highly recommend reading the book The Path between the Seas: The Creation of the Panama Canal, by David McCullough. It is loaded with highly detailed information from the very beginning of the canal construction through the completion of the project 44 years later,
Hope this helps!
Answer:
The answer is National Security argument
Explanation:
In this question, the woman is arguing on the basis of national security as the over-reliance on foreign countries for something as important as one used in making weapons for defense does not appeal to her. From her point of view, she does not argue from an "unfair competition" point of view, neither is she arguing because she is a little player in the industry. Her point is valid as it is a threat to national security to depend on the purchase of a very important item that is used in the manufacture of weapons for defense.
Answer:
Compounds being broken apart using chemical change is called decomposition reaction. An example of this is when Electrolysis is used to break down a compound
"Types of juvenile delinquency", "juvenile delinquency law and prevention, "defining juvenile delinquency" and "factors leading to youth crimes" is the most logical sequence for these elements. The correct sequence is actually "D", "A", "C" and "B". I hope that this is the answer that has come to your desired help.
