Global population was around 1.6 billion in 1990—today it is around 7.2 billion and growing. Recent estimates on population growth predict a global population of 9.6 billion in 2050 and 10.9 billion in 2100. Unlike Europe and North America, where only three to four per cent of population is engaged in agriculture, around 47 per cent of India’s population is dependent upon agriculture. Even if India continues to do well in the service sector and the manufacturing sector picks up, it is expected that around 2030 when India overtakes China as the world’s most populous country, nearly 42 per cent of India’s population will still be predominantly dependent on agriculture.

Question: Which of the following is the most logical and rational inference that can be made from the above passage?

The correct answer is: "Prosperity of agriculture sector is of critical importance to India."

This is a logical inference question, which means we must identify the conclusion that is most directly and strongly supported by the evidence presented in the passage — without overstretching or reading in information that isn't there. Let's analyse the passage step by step.

Step 1: Identify the key facts stated in the passage.

The passage presents the following data points:

• Global population is growing rapidly, from 1.6 billion (1990) to 7.2 billion today, and projected to reach 9.6 billion by 2050.
• Currently, around 47% of India's population is dependent on agriculture.
• Even with growth in the service sector and manufacturing, around 42% of India's population will still be predominantly dependent on agriculture by 2030.
• By 2030, India is expected to overtake China as the world's most populous country.

Step 2: Understand what the passage is emphasising.

The central message is that agriculture is not a shrinking or transitional sector for India — it is a persistent and dominant livelihood for a very large share of the population. Even as other sectors grow, nearly half the population remains tied to farming. This makes agriculture not just an economic activity, but a foundation of India's social and economic fabric.

Step 3: Evaluate each option against the passage.

Option 1 – "Prosperity of agriculture sector is of critical importance to India"
This is a direct and proportionate conclusion from the facts. If nearly half the population — in a country soon to be the most populous in the world — depends on agriculture, then the health and prosperity of that sector is critically important to the nation's overall well-being. This follows logically and directly. ✅

Option 2 – "Indian economy greatly depends on its agriculture"
While this sounds similar, the passage speaks about population dependent on agriculture — not the contribution of agriculture to GDP or the economy as a whole. In fact, service and manufacturing sectors are also growing. This option slightly distorts the passage's focus from "people's livelihoods" to "economic output." It is a weaker and less precise inference. ❌

Option 3 – "India should take strict measures to control its rapid population growth"
The passage mentions population growth as context, but it does not suggest that population growth is a problem that needs strict control. Drawing a prescriptive policy conclusion like this goes well beyond what the passage states. This is reading too much into the data. ❌

Option 4 �� "India's farming communities should switch over to other occupations"
The passage makes no such recommendation. It actually implies the opposite — that even with sectoral growth, farming will remain the dominant occupation. Suggesting a switch is a prescriptive assumption not supported by the passage. ❌

Step 4: Confirm the correct inference.

A logical inference must be:

• Supported by the facts in the passage
• Not an exaggeration or assumption beyond the stated data
• The most rational conclusion one can draw

Given that ~47% of India's population currently depends on agriculture and ~42% will still do so by 2030 (even as the country becomes the most populous in the world), it is an unavoidable and well-grounded conclusion that the prosperity of the agriculture sector is of critical importance to India. If farming fails, nearly half the population suffers — making this inference both logically sound and directly proportionate to the evidence presented.

Therefore, Option 1 is the most logical and rational inference that can be drawn from the passage.
