Explanation:

• Academic Bank of Credit (ABC),proposed under the National Education Policy (NEP) 2020, was unveiled in July 2021.
• Set-up by the University Grants Commission (UGC).
• Under the ABC, students will be given multiple entry and exit options.
• This enables students to leave a degree or course and get a corresponding certification and rejoin studies after a certain time and be able to start from where they had left.
• It will also provide students with the flexibility to move between institutes while pursuing one degree or leave a course.

Ans: (a)

Explanation:

• It is a Water-Distribution Treaty, signed in Karachi on 1960, between India (Pm Jawaharlal Nehru) and Pakistan (President Ayub Khan), brokered by the World Bank.
• Under the provisions of the Indus Waters Treaty, signed between India and Pakistan in 1960, all the waters of the eastern rivers — the Sutlej, Beas, and Ravi — amounting to around 33 MAF (million acre-feet) annually is allocated to India for unrestricted use.
• The waters of western rivers — Indus, Jhelum, and Chenab — amounting to around 135 MAF annually are largely for Pakistan.

Ans: (c)

Explanation:

• The researchers use the non-observation of the lensing signatures to assess what fraction of the dark matter could be made of black holes. Gravitational lensing is useful to cosmologists because it is directly sensitive to the amount and distribution of dark matter.
• What is gravitational lensing? How does it work?
  • Gravitational lensing is an effect of Einstein’s theory of general relativity – simply put, mass bends light.
  • The gravitational field of a massive object will extend far into space, and cause light rays passing close to that object (and thus through its gravitational field) to be bent and refocused somewhere else.
  • The more massive the object, the stronger its gravitational field and hence the greater the bending of light rays – just like using denser materials to make optical lenses results in a greater amount of refraction.

Explanation:

• Better macroeconomic and societal indicators are needed to reflect the contribution of biodiversity and ecosystem services to human well-being.
• One approach that is gaining momentum across the globe is “green accounting” whereby national accounts are adjusted to include the value of nature´s goods and services
• Green accounting allows the computation of income for a nation by taking into account the economic damage and depletion in natural resource base of a country.
• It is a measure of sustainable income level that can be secured without decreasing the stock of natural assets.
