1. Which of the following elements are used in the production of semiconductors?
- Neon
- Palladium
Select the correct answer using the codes given below:
[A] Only 1
[B] Only 2
[C] Both 1 & 2
[D] Neither 1 nor 2
Show Answer
Correct Answer: C [Both 1 & 2]
Notes:
Both neon and palladium are essential in semiconductor manufacturing. Neon is used in the photolithography process for fabricating integrated circuits, while palladium is used to coat electrodes and in plating microprocessors and printed circuit boards. Shortages of these elements can significantly impact semiconductor production globally.
2. With respect to the military weapons in news, terms ‘Stinger’, ‘Igla’, Starstreak’ pertain to which of the following?
[A] MANPADS
[B] Drones
[C] Assault Rifle
[D] Submarines
Show Answer
Correct Answer: A [MANPADS]
Notes:- Man-portable air defense systems (MANPADS) are surface-to-air missiles that can be fired by an individual or a small team of people against aircraft. These weapon systems often are described as shoulder-fired anti-aircraft missiles. They help shield troops from aerial attacks and are most effective in targeting low-flying aircrafts.
- MANPATs or Man-Portable Anti-Tank Systems work in a similar manner but are used to destroy or incapacitate military tanks.
- The United States and the Soviet Union first deployed MANPADS—the Redeye and Strela systems respectively—in the 1960s to provide their infantries with portable anti-aircraft weapons.
- Stinger Missiles (US), Igla MANPADS (Russia), Starstreak (Britain), RBS-70 MANPADS Series (Sweden), Next Generation Light Antitank Weapon or NLAW missiles and Javelin missiles (US and NATO).
3. Mumbai Climate Action Plan was prepared by Brihanmumbai Municipal Corporation (BMC) with the technical support of which of the following agencies?
- World Resource Institute
- C40 Cities Network
- World Bank
Choose the correct answer using the codes given below:
[A] Only 1 & 3
[B] Only 2 & 3
[C] Only 1 & 2
[D] 1, 2 & 3
Show Answer
Correct Answer: C [Only 1 & 2]
Notes:- The Mumbai Climate Action Plan (MCAP) has laid down a 30-year roadmap for the city to tackle the challenges of climate change by adopting inclusive and robust mitigation and adaptation strategies.
- The Brihanmumbai Municipal Corporation (BMC) prepared the plan with technical support from the World Resources Institute (WRI), India and the C40 Cities network.
- The action plan has set short-, medium- and long-term climate goals aimed towards zero emission of greenhouse gas or a net-zero target for 2050.
- Six strategic areas to be focussed—sustainable waste management, urban greening and biodiversity, urban flooding and water resource management, energy and buildings, air quality and sustainable mobility.
