• Earth Hour was observed on March 25 this year.
• Earth Hour is an annual event that takes place on the last Saturday of March.
• Earth Hour, organized by World Wildlife Fund (WWF), is a global grassroots movement uniting people to take action on environmental issues and protect the planet.
  • The event was first introduced in Sydney, Australia, in 2007 by WWF and its partners as a symbolic lights-out event to raise awareness about climate change.
• It is held worldwide to encourage individuals, households, communities and businesses to turn off their non-essential lights for one hour as a symbol for their commitment to the planet.

 ANSWER: A

• A newly proposed ‘pellet-beam’ propulsion system could theoretically beam a heavy spacecraft to outside the confines of our Solar System in less than 5 years.
• The pellet-beam concept was partly inspired by the Breakthrough Starshot initiative, which is working on a ‘light-sail’ propulsion system.
• This system requires two spacecraft – one that sets off for interstellar space, and one that goes into orbit around Earth.
• The spacecraft orbiting Earth would shoot a beam of tiny microscopic particles at interstellar spacecraft.
• Those particles would be heated up by lasers, causing part of them to melt into plasma that accelerates the pellets further, a process known as laser ablation.
• Those pellets could reach 120 km/second(75 miles/second) and either hit the sail of the interstellar spacecraft or repel a magnet within it, helping to propel the spacecraft to huge speeds that would let it whizz out of our heliosphere – the bubble of the solar wind around our Solar System.
• This is new propulsion architecture for fast transit of heavy (1 ton and more) payloads across the Solar System and to the interstellar medium.

 ANSWER: A

• Chenab Railway Bridge, being claimed as world’s highest railway bridge by India, is expected to become operational by 2024.
• Bridge will allow trains to run along Udhampur-Srinagar-Baramulla Rail Link (USBRL) project, and will connect Jammu & Kashmir with the rest of India.
  • It’ll be 35 meters higher than Eiffel Tower in Paris.
• The 3 km long bridge has a design speed of 100 kmph for trains and a lifespan of 120 years.
• The bridge is designed to withstand high wind speed up to 266 Km/Hour, bear earthquake forces of highest intensity zone-V in India.

 ANSWER: B

• Ministry of Home Affairs has decided to further decrease the jurisdiction of “disturbed areas” under Armed Forces (Special Powers) Act (AFSPA), 1958 in Nagaland, Assam and Manipur.
• Earlier, AFSPA was completely withdrawn from Meghalaya in 2018, Tripura in 2015 and Mizoram in 1980s.
• Currently, AFSPA is in effect in Nagaland, Assam, Manipur and parts of Arunachal Pradesh.
• AFSPA grants special powers to armed forces to maintain public order in “disturbed areas”.
• Disturbed areas are declared under Section 3 of AFSPA Act, 1958 when a part or whole state/UT is in such a condition that the use of armed forces in aid of civil power is necessary.
• Disturbed areas are declared by Governor of state or administrator of Union Territory or by Central government.
• Under section 4 of Act, Armed forces can fire upon or arrest anyone who is acting against law & order in disturbed area after giving warning.
• Section 6 of the Act gives legal immunity to persons acting under Act.

 ANSWER: B

• A statue of Nadaprabhu Kempegowda was unveiled at the State Assembly premises in Bengaluru.
• Hailing from dominant agricultural Vokkaliga community in Karnataka, Kempegowda was a chieftain under Vijayanagara Empire.
• He is known as founder of Bengaluru in 16th century and had developed around 1,000 lakes in city to cater to drinking and agricultural needs.
• He prohibited the custom of amputating last two fingers of left hand of unmarried women during “Bandi Devaru“.
• He was multilingual and had authored ‘Gangagaurivilasa’, a yakshagana play in Telugu.

 ANSWER: A

• Marine biologists during routine monitoring of marine litter stumbled upon plastiglomerate (plastic rock) from a beach on Aves island of Andaman and Nicobar Islands.
• Plastiglomerate is a rock composed of sand, rock fragments, shells and other materials held together by plastic.
  • It is a new form of plastic pollution, which scientists described in 2014.
• This is the first such find from India.

 ANSWER: D

• Operation Interflex is a part of United Kingdom’s (UK) commitment of £2.3 billion for military aid and support to Ukraine.
• Under it, UK and other countries including Canada, New Zealand, Australia, Norway, Denmark, Finland, Sweden, Lithuania, and Netherlands are training Ukraine’s military.

 ANSWER: A

• In 1965, Gordon Moore postulated that roughly every two years, the number of transistors on microchips will double.
• Commonly referred to as Moore’s Law, this phenomenon suggests that computational progress will become significantly faster, smaller, and more efficient over time.

 ANSWER: A

• Muskan, the youngest Zila Parishad (ZP) chairperson in Himachal Pradesh from Bilaspur, resigned from her post today.
