Daily Current Affairs Quiz Prelims Practice 2027
- It is a secondary pollutant, not emitted directly by vehicles or industries.
- It forms when sunlight drives reactions among nitrogen oxides and volatile organic compounds.
- It is a greenhouse gas and is harmful to crops.
- Its rate of formation slows down during heatwaves.
Statements 1, 2 and 3 are correct — surface ozone is a secondary pollutant formed in situ rather than emitted directly, it forms via sunlight-driven reactions among NOx and VOC precursors, and it is both a greenhouse gas and damaging to crops and health. Statement 4 is incorrect because heat accelerates formation; ozone spikes during heatwaves and falls back only 3–4 days after they end, so the heat–ozone relationship in the statement is inverted.
Hormuz connects the Persian Gulf to the Gulf of Oman and is bordered by Iran and Oman (the Musandam peninsula), making (b) correct. Option (a) describes the Bab-el-Mandeb strait, not Hormuz; option (c) is wrong because Chabahar lies on the Gulf of Oman outside the strait — precisely why it is valued as a strategic bypass gateway; and option (d) is wrong because the Gulf of Oman opens into the Arabian Sea (Indian Ocean).
- The Nicobarese are a Scheduled Tribe represented by seven Tribal Councils.
- The 'Tuhet' is the traditional extended-kinship unit that anchors Nicobarese society.
- The Andaman and Nicobar Islands fall under the Fifth Schedule of the Constitution.
- The draft rules propose a legally binding five-year tenure for tribal councils.
Statements 1, 2 and 4 are correct — the Nicobarese are a roughly 30,000-strong Scheduled Tribe with seven Tribal Councils, the Tuhet (extended/joint family) is their social foundation, and the draft rules replace the fluid customary cycle with a fixed five-year term. Statement 3 is incorrect because, as a Union Territory, A&N lies outside the Fifth Schedule; tribal protection instead flows from the 1956 and 2009 Regulations, so not every tribal-protected area is automatically Fifth Schedule.
- AB-PMJAY
- eSanjeevani
- Ayushman Bharat Digital Mission (ABDM)
- Tele-MANAS
The correct sequence is AB-PMJAY (2018), eSanjeevani (November 2019), ABDM (September 2021) and Tele-MANAS (October 2022), giving the order 1 – 2 – 3 – 4. Options b and d wrongly swap the 2018 scheme with the 2019 telemedicine platform, while options c and d wrongly invert ABDM and Tele-MANAS.
- A. Shahed-136 | 1. AI-enabled counter-drone system using net capture or collision
- B. Heron | 2. One-way loitering ('kamikaze') munition
- C. Blue Moon | 3. Crewed lunar lander
- D. Iron Drone Raider | 4. Medium-Altitude Long-Endurance ISR drone
The Shahed-136 is a loitering ('kamikaze') munition that circles before diving on its target (A→2), while the Heron (IAI, Israel) is a Medium-Altitude Long-Endurance ISR drone (B→4). Blue Moon is Blue Origin's crewed lunar lander, one of the two Artemis human landing systems alongside Starship (C→3), and the Iron Drone Raider is Israel's AI-enabled counter-drone system that uses net capture or collision instead of costly missiles (D→1).
