Answer: c

Explanation:

Anglers in Sikkim will organise a three-day river festival on the banks of the Rangeet river near Jorethang late this month, seeking to blend catch-and-release fishing with river conservation, adventure tourism and local culture.

About Rangeet River:

• The Rangeet, or Rangit, is a major tributary of the Teesta River, the largest river in Sikkim.
• Course:
  • It originates from a glacier of Mount Kabru at the lower Kanchenjunga
  • The river begins its course from the Himalayan Mountains in the West Sikkim district.
  • A perpetual river, Rangeet is fed by the melting snow of the Himalayas in early summer and the monsoon rains in June-September.
  • The convoluted river joins the Teesta at Teesta Bazaar on the periphery of West Bengal and Sikkim.
  • During its final few kilometres, it forms the boundary between the Sikkim and Darjeeling districts of West Bengal.
  • The river flows past the towns of Pelling, Jorethang, and Legship.
• It is important ecologically as a mountain river system that supports cold-water fisheries (notably trout), provides irrigation and freshwater to local communities, and supplies water for small hydropower projects.
• The banks of the river are enveloped by thick forest cover. Certain areas of the banks are used for terrace farming.
• It is popular among white water rafting enthusiasts because of its turbulent waters.
• The Rangeet Dam is built on this river, which started operating in 2000.
  • It has a 60 MW capacity.
  • It is a 45-metre-high concrete gravity structure of 100 metres length.

Hence option c is the correct answer.

Answer: b

Explanation:

Researchers recently published the first molecular characterization of Marfan syndrome in domestic cats. 

About Marfan Syndrome:

• It is a genetic condition that affects the connective tissue in the body.
  • Connective tissue helps support structures in the body, including organs, bones, and blood vessels.
• It most commonly affects the heart, eyes, blood vessels, and bones.
• Cause:
  • It is a hereditary
  • There’s a change in the fibrillin-1 or FBN1 gene that gives your cells instructions to make fibrillin, a protein.
  • This protein helps connective tissue stay strong and flexible.
• Symptoms:
  • Some people have only mild damage caused by Marfan syndrome, but others can have serious health issues.
  • The symptoms can be different from person to person, even among members of the same family.
  • Common Symptoms Include:
    • Tall, thin body.
    • Long arms, legs, fingers, or toes.
    • A chest that sticks out or sinks in.
    • Crowded teeth and a high, arched roof of the mouth.
    • Heart murmurs.
    • Very poor eyesight or nearsightedness.
    • A curved spine.
    • Flat feet.
  • Changes in the chest wall and spine can cause shortness of breath and back pain.
  • The most serious risk is damage to the aorta, the large blood vessel that carries blood from your heart to the rest of your body.
  • If the aorta becomes weak or tears, the condition can become life-threatening.
  • Changes to the heart and the aorta usually do not produce symptoms until they are advanced or until an emergency occurs.
• Treatment:
  • There’s no cure for Marfan syndrome, so treatment focuses on managing the symptoms and reducing the risk of complications.
  • Treatment usually includes medicines to keep your blood pressure low. This helps reduce the strain on your aorta.
  • Many people with Marfan syndrome eventually require preventive surgery to repair the aorta.

Hence option b is the correct answer.

Answer: c

Explanation:

The Government recently reduced the Basic Customs Duty (BCD) on major imported crude edible oils with a view to moderating domestic edible oil prices. 

About Basic Customs Duty (BCD):

• BCD is a type of tax imposed on goods imported into India.
• It is the principal custom duty levied on imported goods.
• It is levied under Section 12 of the Customs Act, 1962.
• It is calculated as a percentage of the assessed value of the goods, i.e., it is fixed based on the ad-valorem, with rates set out in the Customs Tariff Act, 1975.
• There is no specific rate of BCD, and it can vary on the basis of the country of origin and the types of goods being imported.
• The Central Government holds the power to exempt specific goods from BCD.
• Purpose:
  • It protects domestic manufacturers from underpriced foreign competition by raising the landed cost of comparable imports.
  • It generates revenue for the central government, since customs duty remains a significant indirect tax stream.
  • It also functions as a policy lever. The government raises or removes BCD on specific inputs to support sectors such as electronics, renewable energy, and defence manufacturing.
  • Because BCD applies before Integrated GST (IGST) on imports, it directly affects the final landed cost that a business builds into its pricing.
• The calculation of BCD involves several steps:
  • Classification of Goods: Imported goods are classified under specific Harmonized System (HS) codes, which determine the applicable duty rate.
  • Assessment of Value: The value of the goods is assessed based on the transaction value, including the cost of goods, insurance, and freight (CIF).
  • Application of Duty Rate: The BCD rate for that HS code is applied to the assessed CIF value to arrive at the duty payable.

Hence option c is the correct answer.

Answer: d

Explanation:

Saudi Arabia quietly exited the China-led mBridge digital currency project in 2025, saying it was part of its original plan. 

About mBridge Project:

• mBridge is a cross-border payments platform designed to allow central banks to transact directly using central bank digital currencies (CBDCs).
• It is a joint project launched in 2021 between the Bank for International Settlements (BIS) innovation hub and the Bank of Thailand, the Central Bank of the United Arab Emirates, the Digital Currency Institute of the People’s Bank of China, and the Hong Kong Monetary Authority.
• The project aimed to explore a multi-CBDC platform shared among participating central banks and commercial banks, built on distributed ledger technology (DLT) to enable instant cross-border payments and settlement.
• Need for mBridge:
  • The project aimed to tackle key inefficiencies in cross-border payments, including high costs, low speed, and operational complexities.
  • It also aims to address financial inclusion concerns, particularly in jurisdictions where correspondent banking (which connects countries to the global financial system) has been in retreat, causing additional costs and delays.
  • The system is designed to potentially reduce the need for the US dollar to act as an intermediary currency.

●       How does mBridge work?

• The platform uses blockchain technology, which makes all the participating banks connect to the same network, which is shared among them.
• The blockchain is a shared digital record which helps keep in tracking the transactions, including maintaining who has paid whom and how much.
• Participating central banks as well as monetary organisations use their own computers on the mBridge network, which are called as validating nodes.
• They play a role in maintaining the transactions that have taken place as well as also help in maintaining the shared digital record to maintain clarity on the transactions that have taken place.
• This means that international payments no longer pass through several banks, rather they are settled directly through one shared platform, mBridge in this case.

●       Why is it seen as China-led?

• The mBridge platform is often said to be a China-led cross-border digital currency project.
• China has been involved in this project since the very beginning in 2021, as the Digital Currency Institute of the People’s Bank of China was one of the founding partners.

Hence option d is the correct answer.

Answer: a

Explanation:

Archaeologists recently unearthed a monumental 2,700-year-old tomb at Vulci, an important ancient Etruscan town north of Rome. 

About Etruscan Civilization:

• They were a pre-Roman Mediterranean civilization that flourished between the 8th and 3rd centuries BCE.
• The Etruscans, also known as the Tyrrhenians, inhabited the area that is now Italy.
• Their country was called Tuscia, or Etruria, which was located in the central part of the Italian peninsula.
• Etruria was bounded on the west by the Tyrrhenian Sea, on the north by the Arno River, and on the east and south by the Tiber River.
• They played a significant role in the cultural and political development of early Rome.
• They established a confederation of twelve city-states.
• One of the key features of Etruscan society was their system of government.
  • The Etruscans were ruled by a series of kings, who were elected by the members of the aristocratic families.
  • This system of government was highly decentralised, with each city-state having its own king and its own system of laws and governance.
• Etruscan society was marked by a high degree of leisure and luxury, evident in their art, elaborate burial practices, and the status of women, who experienced more equality compared to many contemporary cultures.
• The Etruscans were skilled traders and builders, known for their wealth derived from local metal deposits and fertile agricultural land.
• The Etruscans possessed the biggest iron reserves in the whole of the western Mediterranean.
• They had a strong navy and dominated the seas on the western coast of Italy.
• They developed advanced architectural techniques, including the use of the arch and vault.
• Etruscans were the first in the Mediterranean region to construct a city on the basis of a grid plan.
  • In this plan, most of the streets were laid in a north-south direction with a few streets crossing them from the east-west direction.
• Despite their many accomplishments, the Etruscan civilization began to decline in the 5th c. BC, as they were gradually absorbed into the expanding Roman Republic.
• The Romans were heavily influenced by Etruscan culture and adopted many of their traditions and practices, such as their system of government, their religious beliefs, and urban planning.

Hence only statement 1 is correct.
