Answer: c

Explanation:

Scientists recently confirmed that Moken sea nomad children living on the Andaman Sea can see underwater with twice the clarity of other children, constricting their pupils to dolphin-like precision through years of ocean training.

About Moken People:

• Often called sea nomads or sea gypsies, the Moken are seafaring people who have been living off the coast of Thailand and Myanmar on the Andaman Sea.
• Their name, in their own language, means “sea drowned.”
• The Moken have lived across the Andaman Sea for centuries, moving between the roughly 800 islands that stretch along the coastlines of Myanmar and Thailand.
• They are one of the last sea nomad peoples in the world.
• Traditionally, they travel in wooden vessels called kabang, moving with the seasons and tides.
• Fishing, diving, and gathering shellfish form the backbone of their subsistence lifestyle, and from a very young age, Moken children are immersed in the marine environment.
• Possessing a rich knowledge of the reefs, the Moken have exceptional underwater skills such as free diving and spear hunting.
• They have their own language, which is Austronesian, a language used in Southeast Asia and Oceania.
• Most Moken are stateless as a result of their nomadic lifestyle. They have no citizenship in Thailand or Myanmar.
• They came into the international spotlight following the 2004 Indian Ocean tsunami because they managed to sense warning signs from nature in the form of the water receding back into the ocean and moving away from dangerous areas.

Hence option c is the correct answer.

Answer: c

Explanation:

The Union Health Ministry has urged people to monitor alanine aminotransferase (ALT) levels as an early indicator of liver injury.

About Alanine aminotransferase (ALT):

• Alanine aminotransferase (ALT), also known as serum glutamic-pyruvic transaminase (SGPT), is an enzyme found predominantly inside liver cells, though it exists in other parts of your body.
• It plays a key role in the metabolism of amino acids, breaking them down to produce energy for the body’s essential functions.
• Usually, you will have low levels of ALT in your blood. But when liver cells are damaged due to conditions like inflammation, infection, or injury, the enzyme leaks into the bloodstream.
• High levels of ALT in your blood may be a sign of a liver injury or disease.
• However, since ALT is also present in smaller amounts in other parts of the body, an elevated ALT level does not necessarily indicate liver disease and should prompt further evaluation to identify the source of the abnormality.
• ALT is one component of the liver function test, which includes other liver enzymes and measures of liver function.
• Although ALT is a sensitive indicator of ongoing liver injury, patients can still have significant liver disease despite normal ALT values.
• ALT testing is performed on a blood sample, with results typically available within a few hours.
• Although many laboratories consider ALT levels below 40 units per litre as normal, interpretation depends on the patient’s condition.
  • For example, lower thresholds are often applied in people with chronic hepatitis B or C.

Hence option c is the correct answer.

Answer: b

Explanation:

The government has so far approved or accorded in-principle approval to 33 projects under the Urban Challenge Fund (UCF), Union minister informed the Lok Sabha recently.

About Urban Challenge Fund (UCF):

• It is a new centrally sponsored scheme of the Ministry of Housing and Urban Affairs.
• It supports transformative and bankable urban projects through competitive “challenge-mode”.
• Financial Outlay: Total Central assistance of ₹1 lakh crore.
• Tenure: It will be operational from FY 2025–26 to FY 2030–31, with an extendable implementation period up to FY 2033–34.
• Under UCF, cities will be supported to do projects under three verticals,
  • Creative development of cities
  • Cities as growth hubs
  • Water and sanitation
• Cities will be expected to take reforms in urban governance, urban finance, and urban planning.
• Features:
  • Centre’s assistance under the scheme is capped at 25 percent of the cost of bankable projects.
    • This will lead to a total investment of ₹4 lakh crore in the urban sector in the next five years.
  • At least 50 percent of the project cost has to be mobilised through market-based sources such as municipal bonds, bank loans, and public-private partnerships (PPPs).
  • The remaining share may be contributed by States, Union Territories (UTs), Urban Local Bodies (ULBs), or other sources.
  • Projects will be selected through a transparent and competitive challenge mode, ensuring support to high-impact and reform-oriented proposals.
  • Private sector participation will be encouraged through structured risk-sharing frameworks and benchmarking of service delivery standards.
  • Credit Repayment Guarantee for Smaller Cities:
    • In order to facilitate first-time access to market finance for all Cities/ULBs in Northeastern & Hilly States and smaller ULBs (<1,00,000 population) in other States/UTs, a Credit Repayment Guarantee Scheme of ₹5,000 crore has been approved.
    • The scheme will provide a Central guarantee of up to ₹7 crore or 70 percent of the loan amount (whichever is lower) for first-time loans.
  • The Fund will cover:
    • All cities with a population of 10 lakh or more (2025 estimates);
    • All State and Union Territory capitals not covered above; and
    • Major industrial cities with a population of 1 lakh or more
    • Additionally, all ULBs in hilly states, Northeastern States, and smaller ULBs with a population below 1 lakh will be eligible for support under the Credit Repayment Guarantee Scheme.
    • In principle all cities will be covered under UCF.

Hence option b is the correct answer.

Answer: c

Explanation:

Recently, the India Meteorological Department (IMD) rejected reports that Assam and Nagaland had experienced cloudbursts over the preceding few days and that they were responsible for the Upper Assam floods.

• A cloudburst is an extreme weather phenomenon characterized by an intense and sudden downpour of rain.
• It can also occur in plains, the phenomenon is most common in hilly regions.
• According to the India Meteorological Department (IMD), a cloudburst occurs when a small area, around 20-30 sq. km, receives 10 cm or more of rain in an hour.
• Impact: Short spells of very heavy rainfall over a small geographical area can cause widespread destruction.
• How does a cloudburst form?
  • It typically begins with convection, when warm, moist air rises rapidly into the atmosphere.
  • In mountainous areas, this is called orographic lifting, where monsoon winds are forced upwards by steep slopes.
  • As the air rises, it cools and condenses into towering cumulonimbus clouds, which can be up to 15 km tall.
  • Water droplets begin to form inside these clouds and, as they get heavier, they would normally fall as rain.
  • However, if the currents of warm air moving upwards are very strong, they can keep the raindrops suspended in the air for longer.
  • Eventually, the weight of the water droplets becomes too great for gravity and the updrafts to hold, or the updrafts weaken, sending the water plummeting down like an ocean descending on the ground.

Hence both statements are correct.

Answer: b

Explanation:

Recently, the Parliamentary committee on External Affairs has recommended that India should appoint a Polar Ambassador and urged the government to seek “full-fledged membership” of the Arctic council.

About Arctic council:

• It was established by the Ottawa Declaration in 1996.
• It is an intergovernmental forum for addressing issues related to the Arctic Region.
• It is not a treaty-based international organization but rather an international forum that operates on the basis of consensus.
• Member Countries: Canada, Denmark, Finland, Iceland, Norway, Sweden, the Russian Federation, and the United States
• It has six Permanent Participants (PP) groups representing the indigenous people of the Arctic.
• Observer States: Observer status in the Arctic Council is open to non-arctic states, inter-governmental and inter-parliamentary organizations, global and regional and non-governmental organizations.
  • India is currently one of the 13 observer countries (France, Germany, Netherlands, Poland, Spain, U.K., India, China, Japan, Singapore, South Korea, Italy and Switzerland) of the Arctic Council.
  • The observer countries do not have decision making powers. They also can’t make financial contributions or undertake research in the arctic directly.
• Function: The Council focuses its work on matters related to sustainable development, the environment, and scientific cooperation.
• Traditionally, the Council is chaired by the foreign minister of the country holding the chairmanship.

Hence only statements 1 and 3 are correct.
