Final answer:
The best unit to report the population of a major global city would depend on the actual population of the city. If the population is in the range of a few hundred thousand to a few million, it would be appropriate to report the population in millions. If the population is in the billions, then it would be appropriate to report it in billions. The best way to determine how to report the population is to use the most appropriate unit to provide clarity and avoid confusion.
Step-by-step explanation:
The best unit to report the population of a major global city would depend on the actual population of the city. If the population is in the range of a few hundred thousand to a few million, it would be appropriate to report the population in millions. For example, if a city has a population of 2.5 million, it would be more accurate to report it as 2.5 million rather than 2500 hundred thousand. If the population is in the billions, such as 10 billion, then it would be appropriate to report it in billions.
The best way to determine how to report the population is to use the most appropriate unit to provide clarity and avoid confusion.
In the case of Hundred, millions, billions - the correct answer would be D) Any, depending on the city.
