Solution (b)

Explanation:

• The Miyawaki Method, developed by Japanese botanist Akira Miyawaki, is a technique for creating dense, native, self-sustaining mini-forests rapidly in small urban spaces. It is a revolutionary method for creating dense forests in limited spaces. It is also referred to as the ‘pot plantation method’, it involves planting trees and shrubs close to one another to accelerate their growth. Hence, statements 1 and 2 are correct.

• The competition for sunlight encourages trees to grow more vertically and less laterally. It emphasizes planting only plant species native to the local area. This fosters a more resilient and naturally balanced ecosystem. Plants grow 10 times faster with this technique, making it a practical solution for urban areas. Hence, statement 3 is not correct.

Solution (d)

Explanation:

• Molecular cloud is an interstellar cloud of gas and dust in which molecules can form, the most common of which is hydrogen (H2). The size of these clouds can be from a few light years up to 600 light years. Their total mass can reach several million solar masses. Molecular clouds with dimensions of more than about 15 light years are also called giant molecular clouds. Hence, statement 1 is correct.

• The complex interplay between three key forces, namely gravity, magnetic fields, and turbulence, determines how these clouds collapse to form stars. The central regions of these clouds are completely hidden from view by dust. These clouds do not last for a very long time. After the new stars are born, their solar winds blow away the remaining gas and dust. Hence, statements 2 and 3 are correct.

Solution (c)

Explanation:

Zanskar river is a major left-bank tributary of the Indus River, flowing entirely within the union territory of Ladakh in northern India. It drains the remote Zanskar Valley in the northwestern Himalayas. The entire catchment area of the Zanskar River has been formed by the action of glaciers. Its valley is U-shaped, and a number of hanging valleys open into it. Hence, statements 1 and 2 are correct.

Solution (c)

Explanation:

• NITI Aayog recently released the Export Preparedness Index 2024, a comprehensive assessment of export readiness across India’s States and Union Territories (UTs). It recognizes the diversity of subnational economic structures and their critical role in advancing India’s global trade ambitions. The first edition of the EPI was published in August 2020 and this is the 4th edition. Hence, option c is the correct answer.

Solution (b)

Minimum initial and annual contribution is ₹250 and there is no maximum limit on contribution. The contribution can also be gifted by relatives and friends. Hence, statement 1 is correct.

• It is regulated and administered by the Pension Fund Regulatory and Development Authority (PFRDA). It is open to all Indian citizens, including NRI/OCI, below 18 years of age. It expands the pension net to the younger population, ensuring “Viksit Bharat@2047” goals of a pensioned society. Hence, statement 2 is INCORRECT.
