This question tests naming the category for items used to perform farming tasks. Utensils like axes, shovels, ploughs, and spades are tools. A tool is a handheld device that helps you carry out a job such as digging, cutting, or turning soil. Fertilizer and seeds are inputs—things added to aid crop growth—while irrigation is about providing water. So the best term for these farming aids is tools.

As people become more affluent, their demand for meat, including beef, increases. Beef has relatively high income elasticity, so when incomes rise, households are willing to spend more on meat. This boosts the domestic market because more beef is bought and consumed at home, whether production rises to meet it or imports fill the gap. In short, rising affluence drives stronger domestic demand for beef. The other options describe situations that aren’t the usual immediate result of increasing wealth. An export-led pattern would require a country to prioritize selling more beef abroad than it consumes domestically, which isn’t the typical outcome of rising incomes. Import competition can occur, but the primary trend when affluence grows is a growing domestic market to satisfy higher domestic consumption.

Investing in machinery is about physical capital—durable assets used to produce goods. A harvester that can process 30 tons of wheat per day represents a fixed asset whose value and productivity stay with the business over many seasons, increasing overall output. That’s why capital is the best fit. Chemicals are inputs consumed in production, not the assets themselves; research and development refers to creating new knowledge or products; and processes describe the methods used, not the actual investment in equipment.

The main idea here is that farming happens through a series of actions that transform inputs into crops. Ploughing, sowing, and harvesting are the steps in the production sequence—the actions taken to prepare the soil, plant seeds, and then collect the crop. These are processes: they describe what happens in the farming cycle to convert resources like soil, seeds, water, and labour into the harvest. Expenditure refers to money spent, physical inputs are the resources themselves (soil, seeds, tools), and human inputs are the people and management involved. So the sequence of activities is best described as processes because it captures the actual steps that produce the final yield.
