Answer:
The Answer is C the States
The answer would be Economic Growth.
The GATT (now WTO, World Trade Organization) was a trade agreement between 23 founding member nations to promote international trade and cooperation. This was achieved by eliminating trade barriers between the member nations such as tariffs/taxes or quotas
It is worth noting that the GATT only operated with tangible goods, where the WTO today operates with goods and services.
(The GATT was founded in 1947 and lasted until 1994 when the WTO was formed.)
Social tensions were similar to ethnic and religious. Immigrants wanted to go westwards and establish new states, and locals wanted to get land and become politicians in new states, which caused problems. For example, Mormons were religiously prosecuted constantly and had to go as far as Utah in the end. Political tensions were party related and slavery related. They grew out of ideas on whether new states should be slave states or not.
Representational structure is most likely the term you're looking for.
If you are familiar with the art of Pablo Picasso, you have a good example of someone who produced works of analytic cubism. There's not a use of perspective to give shape or depth to the figures. Instead, shapes are overlapped and structured in ways that represent the idea being presented. Do an Internet search for Picasso's 1909 painting, "Houses on the Hill Horta de Ebro," and you'll see the effect. You get a feeling of houses on a hill, even though everything is presented in layered cubic shapes.
