How Well Do You Know Economics?

Explanation
Microeconomics is the correct answer because it focuses on analyzing the behavior of individual agents, such as households and firms, and how they make economic decisions. It also examines the interactions between these agents in specific markets, such as the market for goods and services or the labor market. Microeconomics aims to understand how these interactions shape the allocation of resources and the outcomes of economic transactions at a smaller scale. On the other hand, macroeconomics analyzes the overall performance and behavior of the entire economy, including factors like inflation, unemployment, and economic growth.

Explanation
Macroeconomics is the correct answer because it is the branch of economics that studies the overall performance and behavior of an economy as a whole. It analyzes aggregated variables such as national income, employment, inflation, and economic growth. Macroeconomics also examines the impact of government policies and interventions on the economy. In contrast, microeconomics focuses on individual economic units such as households, firms, and markets, while isoeconomics is not a recognized field of study in economics.

Explanation
Positive economics is said to describe "what is". Positive economics is the branch of economics that focuses on objective analysis and the study of economic facts and phenomena as they are, without making value judgments or prescribing what should be. It seeks to understand and explain economic behavior and outcomes based on empirical evidence and data. Unlike normative economics, which deals with what ought to be, positive economics is concerned with describing and analyzing the actual economic reality. Therefore, positive economics is the correct answer as it accurately describes the study of "what is" in economics.

Explanation
Normative economics is the branch of economics that deals with the advocating of "what ought to be." It focuses on value judgments and subjective opinions about how the economy should be structured and how resources should be allocated. It involves making recommendations and policy prescriptions based on ethical considerations and personal beliefs. This is different from positive economics, which focuses on objective analysis of economic phenomena without making value judgments. Isoeconomics and negative economics are not recognized branches of economics, so they are not relevant to the question.

Explanation
Adam Smith defines economics as a branch of the science of a statesman or legislator with the twofold objectives of providing a plentiful revenue or subsistence for the people and supplying the state or commonwealth with a revenue for the public services. This means that economics, according to Smith, is concerned with the study of how to generate enough resources to ensure the well-being of the people and to finance the necessary functions of the government.

Explanation
Production is defined as the conversion of inputs into outputs. It refers to the process of creating goods and services using various resources such as labor, capital, and raw materials. This involves transforming inputs into finished products or services that can be consumed or used by individuals or businesses. Production is a fundamental economic concept that plays a crucial role in the overall functioning of an economy.

Explanation
Opportunity cost refers to the economic cost of production. It represents the value of the next best alternative foregone when making a decision. In the context of production, it refers to the cost of choosing one production option over another, considering the potential benefits that could have been obtained from the alternative option. Therefore, opportunity cost is a crucial concept in economics that helps in decision-making and resource allocation.

Explanation
The correct answer is "Production–possibility frontier". The Production–possibility frontier refers to a graphical representation of the different combinations of two goods that can be produced using limited resources. It shows the maximum output of one good that can be produced given the level of production of the other good. The frontier represents the efficiency of production, and any point on the curve represents the optimal allocation of resources.

Explanation
The correct answer is "Demand." Demand refers to the quantity of a good or service that buyers are willing and able to purchase at various price levels. It represents the relationship between price and the quantity demanded, showing the quantity buyers are willing to purchase at each unit price.

Explanation
Uncertainty refers to the unknown prospect of gain or loss in economics, whether it can be quantified as risk or not. It represents a situation where the outcome is unpredictable or unknown, making it difficult to make accurate decisions. Unlike risk, which can be measured and assessed, uncertainty involves factors that are difficult to quantify or predict. In economics, uncertainty can arise due to various factors such as changes in market conditions, technological advancements, political instability, or natural disasters.
