Today, one of mexico city’s greatest technological challenges is
a. arable land
b. sinking land
c. extreme drought
d. population decline

The correct answer is Option b) Sinking Land

Mexico City is the capital of Mexico and is one of the largest cities in the world by population.

Despite being the capital and the economic hub of the country, it is facing a huge problem of sinking.

In the last 60 years, the city has sunk several feet since it was developed on top of soft land with a large aquifier beneath it.

As the population of the city grew, the aquifer has reduced in size. Today, in some extreme cases, some parts of the city are sinking by over 1 feet every year.
