The correct answer is A. The hills forced the Inca to build terraces to farm.

Explanation

The Incas were a prehispanic civilization located in South America in the current Peruvian territory. This civilization was characterized by its innovative construction methods because they developed a method to build in the mountain chain of the Andes. Indeed, their territory was characterized by many steep hills that made it difficult to build houses, ways, and farming. But Incas used rocks to build walls to hold the soil creating flat surfaces known as terraces and these were used to grow crops, built houses, among others. According to the above, the correct answer is A. The hills forced the Inca to build terraces to farm.

relations between the soviet union and the united states were driven by a complex interplay of ideological, political, and economic factors, which led to shifts between cautious cooperation and often bitter superpower rivalry over the years. the distinct differences in the political systems of the two countries often prevented them from reaching a mutual understanding on key policy issues and even, as in the case of the cuban missile crisis, brought them to the brink of war.

the united states government was initially hostile to the soviet leaders for taking russia out of world war i and was opposed to a state ideologically based on communism. although the united states embarked on a famine relief program in the soviet union in the early 1920s and american businessmen established commercial ties there during the period of the new economic policy (1921–29), the two countries did not establish diplomatic relations until 1933. by that time, the totalitarian nature of joseph stalin's regime presented an insurmountable obstacle to friendly relations with the west. although world war ii brought the two countries into alliance, based on the common aim of defeating nazi germany, the soviet union's aggressive, antidemocratic policy toward eastern europe had created tensions even before the war ended.
