Read the given paragraph and answer the following questions.

Inflation, a complex phenomenon affecting economies, manifests in various forms including demand-pull, cost-push, stagflation, and structural inflation. Demand-pull inflation arises when there's a rapid growth in aggregate demand that outpaces aggregate supply, leading to higher prices due to limited goods. Cost-push inflation results from increased production costs, such as wages and raw materials, prompting producers to raise prices to retain profit margins. Stagflation, a term coined by Iain Macleod in 1965, is characterized by slow economic growth, high unemployment, and inflation, posing a significant challenge to policymakers. Lastly, structural inflation occurs in the wake of changes in supply and demand structures, often observed in developing countries, where inadequate supply fails to meet the demand surge, driving prices up. Each type underlines different causes and impacts on the economy, indicating the necessity for tailored policy responses.
