Answer:
Interestingly, many French maps showed zero degrees in Paris for many years despite the International Meridian Conference’s outcomes in 1884. GMT was the universal reference standard – all other times being stated as so many hours ahead or behind it – but the French continued to treat Paris as the prime meridian until 1911. Even so, the French defined their civil time as Paris Mean Time minus 9 minutes and 21 seconds. In other words, this was the same time as GMT.
In 1972, Coordinated Universal Time (UTC) replaced GMT as the world's time standard. France did not formally use UTC as a reference to its standard time zone (UTC+1) until August in 1978.
Standard time, in terms of time zones, was not established in United States law until the Act of March 19, 1918. The act also established daylight saving time in the nation. Daylight saving time was repealed in 1919, but standard time in time zones remained in law, with the Interstate Commerce Commission (ICC) having the authority over time zone boundaries.
Many countries started using hourly time zones by the late 1920s. Many nations today use standard time zones, but some places use 30 or 45 minute deviations from standard time. Some countries such as China use a single time zone even though their territory extends beyond the 15 degrees of longitude.

When scientists discuss the great oxygenation event, they are referring to a time when the transition from the mildly reducing Archean atmosphere-ocean system to the oxygenated atmosphere and shallow oceans of the early Paleoproterozoic that started between ~2.4 and 2.3 Ga and ended between 2.1 and 2.0 Ga.
- here The Great Oxidation Event, also called the Great Oxygenation Event, the Oxygen Catastrophe, the Oxygen Revolution, and the Oxygen Crisis, was a time interval when the Earth's atmosphere and the shallow ocean first experienced a rise in the amount of oxygen.
- in this event Gradually, the accumulated oxygen started escaping into the atmosphere, where it reacted with methane. As more oxygen escaped, methane was eventually displaced, and oxygen became a major component of the atmosphere.
- The Great Oxygenation Event (GOE) was the creation of free oxygen in our atmosphere. It was caused by cyanobacteria doing photosynthesis

Answer and Explanation:
1. Sub-Saharan Africa has a very strong economic dependency, which means that its population has less access to education and resources. The limitation of resources prevents the population from having full access to contraceptive methods that can limit the exacerbated growth of the population that did not have a structure that shelters it efficiently. In addition, deprivation of sex education has prevented families from learning concepts about contraceptive methods, family planning, among others that promote rational population growth. This all contributes to Sub-Saharan Africa's population growth, which is increasingly disproportionate and growing, compared to the rest of the world.
2. The two groups differ in their projections of population growth, because they make analyzes using different factors, at different intensities. This is because the projection of population growth is a subjunctive factor, which has countless variables and can have different analyzes and interpretations.
