For centuries, sugar crystals were made from the evaporated juice of sugarcane, a plant grown only in tropical and subtropical climates. In the 1800s, industrial methods were developed to manufacture crystalline sugar from sugar beets. This allowed for large amounts of sugar to be produced in colder, temperate climate zones. Which of the following geographic concepts best explains the ability of humans to use technology to overcome the limitations of climate and modify the landscape? A) Environmental determinism B) Possibilism C) Cultural relativism D) Contagious Diffusion E) Political Ecology

The hypothetical island country of gilder lies in the mediterranean sea off the coast of france. demographers have studied gilder for the past 50 years. at the beginning of the study, gilder had a population of 20 million. the demographers have measured birth and death numbers, as well as immigration and emigration numbers, as shown in the data table. from the data, calculate the population of gilder for each 10-year period by filling in the population (no) and population (nt) columns in the data table. use this formula to do your calculations: population size: nt = no + (b + i) – (d + e)initial population = 20,000,000
