The import-substitution strategy aims to reduce a country's dependence on imported goods by encouraging domestic industries to produce those goods locally.
This policy promotes self-sufficiency, conserves foreign exchange, and stimulates industrial growth within the country.
By substituting imports with locally manufactured products, domestic production is effectively encouraged.

Upstream oil activities refer to the early stages of petroleum operations, including exploration, drilling, and extraction of crude oil from the earth.
These processes are distinct from downstream activities such as refining and marketing of petroleum products.
Hence, upstream activities primarily involve the exploration of crude oil.

Although several factors affect agriculture in Nigeria, poor implementation of government policies remains a major constraint.
Policies are often well-drafted but poorly executed, leading to limited access to credit, low productivity, and inadequate infrastructure.
Effective implementation is key to improving agricultural output and sustainability.

The Nigerian National Petroleum Corporation (NNPC) was established to supervise and coordinate petroleum operations in Nigeria.
Its core function is to oversee the development of the oil and gas sector, ensuring proper exploration, production, and management of petroleum resources on behalf of the government.

Heavy investment in agriculture increases productivity and mechanisation, ensuring an adequate supply of food for the population.
It also creates employment opportunities and reduces the need for food imports.
Therefore, sufficient food production is the most direct outcome of increased agricultural investment.

When aggregate demand is less than total output, unsold goods accumulate and firms reduce production to match lower demand levels.
This reduction in production causes a decrease in employment and income levels.
Hence, national income will fall until equilibrium between demand and output is restored.

Before the invention of money, exchange of goods and services occurred through the barter system, where commodities were traded directly.
Items like salt, shells, and livestock served as mediums of exchange.
Thus, during the barter era, money existed in the form of commodities.

Economic development involves continuous improvement in living standards and productive capacity over time.
A sustained increase in per capita income indicates that citizens are earning more, leading to better welfare, education, and healthcare.
Therefore, such sustained growth in per capita income signifies economic development.

Gross Domestic Product (GDP) at market price measures the total value of all goods and services produced within an economy, including taxes and excluding subsidies.
An increase in GDP at market price over time reflects economic growth and productivity improvement.

Deficit financing occurs when a government borrows or creates money to cover budget shortfalls instead of raising taxes.
This approach increases public spending, boosts aggregate demand, and encourages investment in key sectors.
Therefore, deficit financing is primarily used to stimulate investment and economic activity.
