UPPCS Prelims 2025 · CSAT (Paper II): What do you understand by the "mizzen-top" ?

<p>It has been part of Nelson's prayer that the British fleet might be distinguished by humanity in the victory which he expected. Setting an example himself, he twice gave orders to cease firing upon the Redoubtable, supposing that she had struck because her great guns were silent; for as she carried no flag, there was no means of instantly ascertaining the fact. From this ship, which he had thus twice spared, he received his death. A ball fired from her mizzen-top, which, in the then situation of the two vessels, was not more than fifteen yards from that part of the deck where he was standing, struck the epaulette on his left shoulder about a quarter after one, just in the heat of action. He felt upon his face on the spot which was covered with his poor secretary's blood. Hardy, who was few steps away from him turning round, saw three men raising him up. "They have done for me at last, Hardy !" said he. "I hope not !" cried Hardy. "Yes", he replied, "my backbone is shot through !" Yet, even now, not for a moment losing his presence of mind, he observed as they were carrying him down the ladder, that the tiller-ropes which had been shot away, were not yet replaced and ordered that new ones should be roped immediately. Then that he might not be seen by the crew, he took out his handkerchief and covered his face and his stars. Had he but concealed these badges of honour from the enemy, England perhaps would not have had cause to receive with sorrow the news of battle of Trafalgar. The cockpit was crowded with wounded and dying men; over whose bodies he was, with some difficulty, conveyed and laid upon a pallet in the midshipmen's berth. It was soon perceived, upon examination, that the wound was mortal. This, however, was concealed from all, except Captain Hardy, the Chaplain, and the medical attendents. He himself, being certain, from the sensation in his back and the gush of blood felt momentarily within his breast, that no human care could avail him, insisted that the surgeon should leave him and attend to those to whom he might be useful.</p>

How is deflation done? Most countries use a method called ‘double deflation’, where input and output prices are deflated separately. Consider a manufacturer importing oil for use in production. If oil prices fall, output prices do not and quantities remain the same, real value added should not change. But if the same deflator is used for inputs and outputs, as in India, it would look as if the manufacturer had become more productive.

India is starting to deploy AI for critical use cases such as weather forecasting, pest detection and control, and crop yield optimisation. However, penetration is limited to a small subset of tech-savvy farmers. In the US and in Europe, generative AI tools have started offering precision farming at scale, integrating large datasets to provide real-time agronomic insights. For at-scale integration and accessibility of AI tools in India, it would be helpful to develop Indian languages-based AI tools for smallholder farmers, partner with AgTechs to create affordable AI solutions, and disseminate AI-based advisory services through government programmes.

The process by which countries close their labour-productivity gap with the technology leader is based on convergence theory. The convergence model divides economic eras into three phases : the breakaway, the catch-up, and the fine-tuning phase. It also divides economic entities into two categories : the technology leaders and the technology followers. The process begins with the development of a new technology, such as scavenging three million years ago (MYA), hunting—one MYA, farming—12 thousand years ago, and industrial technology—a little more than 200 years ago. During the breakaway phase, the per capita income of the technology leaders (e.g., Western Europe and North America in the industrial era) rises, but is unchanged for the technology followers. In the catch-up phase, the followers adopt the new technology and close their per capita income gap with the technology leaders. In the fine-tuning phase, where participants try to extract the remaining benefits from an increasingly exhausted technology, leaders and followers have similar per capita incomes.
