The correct answer is D. The land has subsided about 30 feets in the last 100 years, and the rate is increasing.
Explanation
Mexico City is the capital of Mexico, a country in North America. This country during its pre-Hispanic stage was inhabited by civilizations such as the Mayas and the Aztecs who built great empires; the Aztecs built their main city Tenochtitlan on Lake Texcoco, later with the arrival of the Spanish this city was occupied by the colonizers who built houses and buildings in this area filling sectors of this immense lake. Over time, this lake seems to have been covered forming underground water sources such as aquifers, at the same time the city evolved and its infrastructure increased radically. Today this city is suffering from subsidence that has caused the buildings and the surface in general, to have sunk at least thirty feet during the last hundred years, because when Mexico City was built on Lake Texcoco, they were Aquifers and groundwater sources are used to supply water to the city, so they leave empty spaces in the sub-layers of the ground causing buildings and everything on the surface to sink. Additionally, during the last ten years, this pattern has increased making that the surface sink faster than before. According to the above, the correct answer is D. The land has subsided about 30 feet in the last 100 years, and the rate is increasing.
