Answer 2

The term 'megacity' refers to metropolitan areas with a total population of more than 10 million people. The definition of what constitutes a megacity generally refers to the population of an urban agglomeration, that is, it includes people living in the immediate suburbs outside of the established border of the city.

Eggs certainly came before chickens, but chicken eggs did not—you can't have one without the other. However, if we absolutely had to pick a side, based on the evolutionary evidence, we're on Team Egg.
