In these scenario, the pair that correctly pinpoint a variable in this Research is the caffeine — independent variable.
Answer:
Based on the reconstructed temperatures, precipitation changes, and occurrences of extreme climate events, together with historical records on fiscal deterioration, food crises, and the frequencies of popular unrest, rebellions and wars, we identified three principal ways in which climate change contributed to the collapse in the Ming dynasty. Firstly, cooling, aridification, and desertification during a cold period destroyed the military farm system, which was the main supply system for the provisioning of government troops on the northern frontiers; these impacts increased the military expenditure from 64 % of total government expenditure in 1548–1569 to 76 % in 1570–1589 and thus aggravated the national fiscal crisis that occurred during the late Ming dynasty. Secondly, climate deterioration (e.g., cooling, aridification, and an increase in the frequencies of frost- and drought-related disasters, etc.) led to a 20–50 % reduction in the per capita production of raw grain in most areas of China, which resulted in widespread food crises and exacerbated the vulnerability of social structures during the last several decades of the Ming dynasty

Economy:
South America comprises approximately 410 million people living in twelve nations and three territories. It encompasses 6 percent of the world's population.
From the 1930s to 1980s, countries of South America used Import Substitution, an economic policy which replaces foreign businesses as well as imports with domestic production. This was a policy made to produce more development and help grow domestic businesses, which are not competitive with other international industries. However, this policy created a debt crisis in South America.
Politics:
All South American countries are presidential republics with the exceptions of Peru, which is a semi-presidential republic, and Suriname, a parliamentary republic. French Guiana is a French overseas department, while the Falkland Islands and South Georgia and the South Sandwich Islands are British overseas territories. It is currently the only inhabited continent in the world without monarchies; the Empire of Brazil existed during the 19th century and there was an unsuccessful attempt to establish a Kingdom of Araucanía and Patagonia in southern Argentina and Chile. Also in the twentieth century, Suriname was established as a constituent kingdom of the Kingdom of the Netherlands and Guyana retained the British monarch as head of state for 4 years after its independence.
