D. The cultivated soils had poor drainage and caused salt deposits to be left behind in the soil.

Explanation:

Mesopotamian civilisation is known as the land between two rivers, the Tigris lied in the north and Euphrates lied in the south. the region used to experience seasonal rainfall due to which the land was flooded in the winter and spring while the water was scarce during the other seasons. Mesopotamia was scarce of the resources. Historians consider war and environmental changes as the main reason for its decline. Irrigation techniques utilised by the Mesopotamian also played an important role in its decline because if we leave  irrigation water on the fields to evaporate it leaves behind mineral salts. These salt concentrate on the upper layer of the soil, it is poisonous for the soil. The concentration of salts was the main reason for its collapse.

1- in bradbury's  fahrenheit 451, all books are banned and burned upon discovery. in the nazi germany, books considered to be subversive to the regime would be burned to keep the population from generating ideologies that could challenge nazism.

2- was bradbury correct in his literal interpretation of  “where they burn books, they will also ultimately burn people.”? in some way, yes. when knowledge is not only limited, but also controlled, the people tied to it are led to their demise. just like in the novel, people in nazi germany who owned  subversive books were punished not only by the burning of their property, but also by the discrimination that followed after such a public form of consequence. if a person was seen being confiscated  subversive  books, they may be considered as an ally to the jews, which meant pretty much the same as being the enemy back then. because of the extreme exclusion and suffering that followed this punishment, it's almost like dying a slow death.

in this way, the phrase  “where they burn books, they will also ultimately burn people.” is both literal and figurative.
