Question 1 of 5
1. Question
Consider the following statements about Luna Structure
- It is a 1.8-kilometer-wide crater and was created as a result of one of the most monumental asteroid crashes ever witnessed on Earth.
- It remains submerged in the low-lying Delta plains of Amazon River in Brazil.
Choose the incorrect statement:
Correct
Solution (b)
Statement Analysis
Statement 1 Statement 2 Correct Incorrect · It is a 1.8-kilometer-wide crater that has been linked to the ancient Harappan Civilization and is believed to be the outcome of one of the most monumental asteroid crashes ever witnessed on Earth. · It is believed that during impact, this meteorite may have generated a colossal fireball, shockwaves, and subsequent wildfires, potentially engulfing the region inhabited by the people of the ancient Indus Valley civilization thousands of years ago.
· It remains submerged and inaccessible for a significant part of the year due to its location in the low-lying Banni Plains of Gujarat’s Kutch Basin in Gujarat. · Further scrutiny of the rocks surrounding the Luna structure unearthed the presence of elements synonymous with extraterrestrial origins, including Rhodium, Palladium, Osmium, Iridium, and Platinum.
Context: Recently, scientists revealed that a crater could have formed due to one of the largest meteorites on Earth in the last 50,000 years.

· It emotes a play through dancing and singing, where the song is customarily in Manipravala, which is a mix of Sanskrit and Malayalam language.
· The recitation may be performed by the dancer or a vocalist, with the music style being Carnatic. · The dance is characterized by its graceful swaying body movements with no abrupt jerks or sudden leaps.
· More than the footwork, emphasis is given to hand gestures and Mukhabhinaya or subtle facial expressions.
· The hand gestures, 24 in number, are mainly adopted from ‘Hastha Lakshana Deepika’, a text followed by Kathakali.

Question 3 of 5
3. Question
Consider the following pairs of colored carbons and their sources
Colored carbons Sources Black Carbon emitted in incomplete combustion of biomass Red Carbon released through biological particles on snow and ice that reduce albedo. Gray Carbon released through industrial emissions. Teal Carbon stored in freshwater and wetland environments. How many of the above pairs are matched correctly?
Correct
Solution (d)
Option d Correct Scientists use color to classify carbon at different points in the carbon cycle based on carbon function, characteristics, and location. · Blue – Carbon stored in ocean plants and sediments.
· Green – Carbon stored in terrestrial plants.
· Brown – Carbon released by incomplete combustion of organic matter.
· Red – Carbon released through biological particles on snow and ice that reduce albedo.
· Gray – Carbon released through industrial emissions.
· Teal – Carbon stored in freshwater and wetland environments.
· Purple – Carbon captured through the air or industrial emissions.
· Black – Carbon emitted alongside other pollutants when biomass and fossil fuels are not fully combusted.
Black carbon
· It is the dark, sooty material emitted alongside other pollutants when biomass and fossil fuels are not fully combusted.
· It comprises a significant portion of particulate matter or PM, which is an air pollutant. It is a short-lived climate pollutant with a lifetime of only days to weeks after release in the atmosphere.
· It is an important contributor to warming because it is very effective at absorbing light and heating its surroundings. It contributes to warming by converting incoming solar radiation to heat.
Context: According to a study, the residential sector contributes 47% of India’s total black carbon emissions.

Question 4 of 5
4. Question
Consider the following statements
- Vikram-1 Rocket is a single-stage launch vehicle with a capacity to place around 300 kg of payloads in low-earth orbit.
- Vikram-1 Rocket is an all-carbon-fibre-bodied rocket that can place multiple satellites into orbit
- It has been built by NewSpace India Limited (NSIL), a commercial arm of ISRO.
How many of the statements given above are correct?
Correct
Solution (a)
Statement Analysis
Statement 1 Statement 2 Statement 3 Incorrect Correct Incorrect · ‘Vikram-1’ is a multi-stage launch vehicle. · This launch vehicle has a capacity to place 300 kg payloads in the Low Earth Orbit.
· The rocket is an all-carbon-bodied vehicle capable of placing multiple satellites into orbit; it also features 3D-printed liquid engines. · Globally, Vikram-1 is among ‘elite few’ rockets with the capability to deploy orbital satellites, says Skyroot.
· The ‘Vikram’ in the launch vehicles’ name is a tribute to Vikram Sarabhai, the father of India’s space programme.
· It has been built by Hyderabad-based Skyroot Aerospace, a space startup. Being a solid-fuel rocket and using relatively simpler technologies would mean that launching this vehicle would require minimal infrastructure and that the rocket could be assembled and launched within 24 hours from any site. Context: In a significant development towards its upcoming orbital space launch, Skyroot Aerospace, a Hyderabad based space-tech company, has successfully test-fired the Stage-2 of Vikram-1 space launch vehicle, called Kalam-250, at the Satish Dhawan Space Centre (SDSC) in Sriharikota.

Question 5 of 5
5. Question
Which of the following statements about Antarctic Circumpolar Current (ACC) is correct?
Correct
Solution (d)
Option d Correct · Antarctica is surrounded by the Southern Ocean. · Southern Ocean – Southern Ocean is an unbroken body of water with a rushing current that both isolates Antarctica’s coastal ocean and provides essential chemical nutrients for the Antarctic ecosystem.
· ACC – The Antarctic Circumpolar Current (ACC) is the largest wind-driven current on Earth.
· It is the only current that goes all the way around our planet and connects the Atlantic, Pacific, and Indian Oceans.
· It is driven by strong westerly winds and was discovered by Edmund Halley.
· The ACC is a massive flow of water that acts as a barrier separating the Southern Ocean from more northern oceans.
· Antarctica is also the place where waters form that flow through the deep ocean as part of the Global Ocean Conveyor (World Circulation).
Context: Scientists reconstruct history of world’s most powerful ocean current over last 5.3 million years and its link to global climate.
