The correct answer is C. This one is not a consequence of the Westward Expansion.

The term 'Westward Expansion' refers to the conquering of new territories performed by the United States of America after the Declaration of Independence.

A: Confrontation with natives and the superiority of the US nation in the conflict made native end up gathered in reservations.

B: Obviously there was an exchange of knowledge. In this case, the conquerors knew better technologies and transfered them to those who lived in the areas that they started to domine.

C: This was a consequence of the European colonization of the Americas, not the Westward Expansion. Europeans had better health conditions and had developed a stronger inmunitary system and were resistent to certain illnesses, that they spread among the natives who were not, and many of these died because of them.

D: Broad pieces of land which were previously untouched were straightaway dedicated to serve the monetary interests of the conquerors: grass was grazed, water was contaminated, and the reserves of precious minerals were quickly exploited.

The correct answer was B, as Native Americans didn't learn new techniques of irrigation as an effect of westward expansion.

As a result of the American expansion to the west, the native tribes were displaced from their lands. In many occasions armed confrontations between both groups took place, in which the American technological supremacy triumphed over the rudimentary Native weapons.

It was a process that was not developed with total peace, but on the contrary, quite tumultuous and conflictive. Therefore, the Native Americans could not have learned irrigation techniques, since there was no assimilation between the two cultures, but rather a clash between them.
