The World Trade Organization (WTO) was established to promote free and fair trade among member nations. Its main objective is to provide a mechanism for the reduction of tariffs and other trade barriers to facilitate global trade liberalisation. It ensures that trade flows smoothly, predictably, and freely across borders.
Therefore, the WTO plays a crucial role in overseeing trade negotiations and resolving trade disputes between member countries.

In macroeconomics, total output or national income depends primarily on the level of total expenditure. This includes consumption, investment, government spending, and net exports.
An increase in total expenditure leads to a rise in aggregate demand, which in turn increases production and employment levels in the economy.
Hence, the volume of output is largely influenced by how much is spent overall in the economy.

The downstream sector of the oil industry deals with the refining, distribution, and marketing of petroleum products. The loading of crude oil at the terminal is part of this downstream process, as it involves preparing crude oil for transport and export after extraction and storage.
The upstream sector, on the other hand, focuses on exploration and production. Therefore, the loading operation belongs to the downstream sector.

In the short run, average variable cost (AVC) represents the per-unit cost of variable inputs like labour and raw materials. When the cost of labour increases, firms have to pay more for each unit of output produced, causing the AVC curve to rise.
Other factors such as factory expansion or directors’ salaries affect fixed costs and not variable costs. Hence, a rise in labour cost directly leads to an increase in the short-run AVC.

Vertical integration occurs when a firm expands its operations along the production or distribution chain, such as merging with suppliers or distributors. This strategy enables the firm to reduce transaction costs, improve efficiency, and enjoy economies of large-scale production by controlling more stages of the production process.
It helps firms to stabilise supply and demand, reduce costs, and increase profitability.

In co-operative societies, each member has equal voting rights regardless of their level of financial contribution or shareholding. The democratic principle of ‘one member, one vote’ applies, ensuring that decision-making power is distributed equally among all members.
Therefore, voting power lies with the shareholders or members of the co-operative society collectively.

Census data provides information about the size, distribution, and characteristics of a country’s population. Planners use this data to determine the population’s needs and to allocate resources effectively.
Accurate figures ensure equitable distribution of public goods and services such as healthcare, education, and infrastructure. Hence, census figures are vital for efficient resource allocation.

Agriculture remains a major employer of labour in Nigeria, engaging a large portion of the population, especially in rural areas. By providing employment, agriculture contributes to income generation, poverty reduction, and improved living standards.
Other roles such as supplying raw materials and ensuring food security are also significant, but job creation is the most important economic role.

Large-scale farming involves mechanised operations and greater capital investment, which allows for research, technological advancement, and the employment of more labour.
It enhances productivity and efficiency compared to peasant farming, which depends largely on manual labour and traditional tools. Hence, its advantage lies in the ability to engage in research and employ labour on a larger scale.

Localization of industry occurs when several firms within the same industry are concentrated in one geographical area. While it encourages specialisation, it also makes the region vulnerable to industrial decline.
If the dominant industry collapses or relocates, the workers in the region face structural unemployment due to a lack of transferable skills. Hence, the major disadvantage is the risk of structural unemployment.
