Explanation
A pipeline’s maximum capacity is fundamentally constrained by its physical diameter and the pressure it can safely withstand. Unlike road or rail transport, where more vehicles can be added to handle peak demand, a pipeline cannot be easily scaled up once it is laid. Increasing throughput beyond design limits is impossible without constructing parallel lines. Pipelines ensure a continuous supply of energy resources.Explanation
Brownfield Foreign Direct Investment occurs when a company or government entity purchases or leases existing production facilities or acquires an existing company in a foreign country to launch new business activity. This is different from greenfield investment, where a parent company starts a new venture by constructing new facilities. Brownfield investments are often preferred because they allow for faster market entry.I. EPR shifts the responsibility of waste management physically and financially to the producer.
II. EPR encourages manufacturers to design environmentally friendly products.
III. It does not apply to brand owners and importers.
IV. It aims to increase recycling rates.
V. It was mandated in India under the Plastic Waste Management Rules, 2016.
Which of the above statement(s) is/are correct?
Explanation
A policy approach to waste management requires those who produce or import products to be responsible for their entire lifecycle, including disposal and recycling.

By holding companies accountable, it encourages the design of more eco-friendly packaging and promotes higher recycling rates, ultimately reducing the volume of waste.Explanation
Land revenue was the backbone of the Chola economy, and the state maintained a meticulous system of land survey and assessment. The general term used for the land tax or the share of the produce payable to the king by the cultivators was Kadamai.

It was distinct from other levies, such as Vetti (forced labor), and was essential for funding the empire’s massive military and architectural projects.I.

III. High Courts can strike down central laws, subject to appeal to the Supreme Court.
IV. The Chief Justice of India can transfer a judge from one High Court to another without consulting anyone.
V. The law declared by the Supreme Court is binding on all High Courts.
Which of the above statements are correct?
Explanation
Appeals lie to the Supreme Court if a High Court reverses an acquittal to a death sentence. High Courts can strike down central laws, and Supreme Court rulings are binding on them. However, Article 227 gives High Courts supervision over subordinate courts, not the Supreme Court over High Courts. Also, transferring a High Court judge requires the President’s order after specific consultations.| Major Pipeline/Network | Associated Region/Country |

| B. Trans-Arabian Pipeline (Tapline) | ii. India |
| C. COMECON pipeline (Druzhba) | iii. United States |
| D. HVJ Pipeline | iv. Russia and Eastern Europe |
Explanation
Pipeline networks are critical infrastructure in major energy regions. The Big Inch is a historic American pipeline. The Trans-Arabian Pipeline is a major route in the Middle East. The Druzhba pipeline connects Russia to Eastern Europe. In India, the HVJ pipeline is a vital artery for transporting natural gas from western offshore fields to the northern industrial heartland of the country.Explanation
Tiny, pre-production plastic pellets are the fundamental building blocks for nearly all plastic goods. During shipping and manufacturing, these small granules are often spilled, eventually finding their way into rivers and oceans. Because they are small and buoyant, they wash up on beaches worldwide. These pellets are easily mistaken for food by birds and fish, making them a significant source of marine pollution.Explanation
