Answer:
D. United States (railroad trains. It is possible to go from one town to another before midday. The majority of communities maintained their own "time," and high noon was the closest thing to an exact measurement of 12:00 p.m. Every town in a time zone maintained the same time for the convenience of RR scheduling.)
Brief: America's railways implemented a standard time system with four time zones—Eastern, Central, Mountain, and Pacific—on November 18, 1883. All clocks were synced within each zone.
Step-by-step explanation:
Time zones are often political and social constructions driven by economic interests. Even though your associate's sunview is due South, it doesn't always indicate your view is the same in a globalized economy. A difference of even a few kilometers in either direction may be measured in seconds. You must undoubtedly take into account which high noon you anticipate delivery if you anticipate that stage at that time from different places. Thus, a standard time was determined through commerce. However, intercoastal trade could be misunderstood if it coincides with noontime sunrise or sunset. Therefore, based on the average high noon of a number of (perhaps 24) trade zones, a sequence of high noon was determined. This would have been successful, but a few sheep wandered off because they understood that high noon was not the same as commercial demands. Time zones were created as a result of such sovereign judgments, which differ from hourly commercial suggestions (GMT). Central Australia is GMT+9.5, whereas the entirety of India is GMT+5.5. But for the most part, commercial logic maintained. A time zone for which the GMT offset is validated yearly in seconds would be of great relevance.
