Answer:
Poor planning, and disease
Explanation:
The obstacles that the French faced while attempting to build a canal across Panama were diseases and poor planning. The French dealt with constant outbreaks of malaria and yellow fever, which slowed construction and caused the deaths of thousands of workers. The French also did not take into consideration the geographical differences between the Suez Canal region and the Panama region. The French had succeeded in building a canal at sea level in Egypt, and they mistakenly thought a similar design would work in Panama. However, the difference in the Atlantic and Pacific Ocean sea levels, as well as the difference in elevation of the Panamanian terrain, prevented them from building a sea-level canal. The United States knew about these two problems when they undertook the project. They took preventative measures by reducing the disease-spreading mosquito population and using a canal-lock system to overcome the elevation obstacle in Panama.
Answer: Sunday at 12h.
Explanation: The timezones are determined by the meridians, i.e., the longitudinal lines that crosses the Earth from pole to pole.
The initial referential is at GMT, abbreviation for <u>Greenwich</u> <u>Mean</u> <u>Time</u>, located at the Royal Observatory in the United Kingdom.
The Earth rotates 360° in 24 hours, so each 15° is exposed to the Sun for 1 hour. So, at each 15° we add an hour if the location is due to east or subtract an hour if the location is due to west.
Addis Ababa is located at 40°, which is in the band between 30° and 45°.
Counting from the referential, there are 3 timezones going east. So, we add 3 hours to the initial hour:
9h + 3h = 12h
And the day is the same since the difference is only 3 hours ahead.
Thus, fans located at 40° east will watch a football match on Sunday at 12h.
