Question 4 of 10
4. Question
1 pointsConsider the following statements regarding Misagh-2, recently seen in the news:
- It is a long-range ballistic missile system.
- It was developed by Iran.
Which of the statements given above is/are correct?
Correct
Answer: b
Explanation:
Russian forces have begun using an Iranian Misagh-2 man-portable surface-to-air missile system to intercept Ukrainian unmanned aircraft, according to Ukrainian reporting and imagery.
About Misagh-2:
- It is an Iranian man-portable infrared-guided surface-to-air missile system.
- It is a variant of the Chinese QW-2 Vanguard missile system.
- Its main mission is to strike tactical targets such as fighters, attackers, and armed helicopters at low and very low altitudes.
- It can also supply effective air defense for military bases, political and industrial centers, and other important facilities.
- Features:
- The missile itself weighs 11.32 kg at launch, the warhead 1.42 kg, and the complete system 18 kg in the firing position.
- It can engage approaching targets out to 6 km and receding targets out to 5.2 km.
- The maximum effective altitude against jet fighters is about 5 km, and helicopters and subsonic aircraft about 3.5 km.
- It uses a passive infrared (IR) seeker and is designed as a fire-and-forget weapon.
- Once launched, the missile can track the infrared signature of its target without requiring continued guidance from the operator, allowing the firing team to immediately leave its position.
- Its dual-band passive IR seeker has strong resistance to heat flares dispensed by the target and solar/ground heat, thus improving the missile’s performance in day/night, all-weather conditions.
Hence only statement 2 is correct.

Question 5 of 10
5. Question
1 pointsWith reference to Permafrost, consider the following statements:
- It is any ground that remains completely frozen for at least ten years straight.
- More than half of the land area in the Northern Hemisphere has permafrost underneath.
- It is made of a combination of soil, rocks, and sand that are held together by ice.
How many of the above statements are correct?
Correct
Answer: a
Explanation:
Alaska’s thawing permafrost is releasing acid and metals that turn rivers orange, changing water chemistry for dozens of miles.
About Permafrost:
- Permafrost is any ground that remains completely frozen—32°F (0°C) or colder—for at least two years straight.
- While two years is the minimum for permafrost consideration, some regions have had frozen ground for hundreds of thousands of years.
- Scientists discovered the oldest known permafrost in Siberia, which has been frozen for the past 650,000 years.
- Where are they found?
- These permanently frozen grounds are most common in regions with high mountains and in Earth’s higher latitudes—near the North and South Poles.
- It can be found on land and below the ocean floor.
- Its thickness can range from one meter to more than 1,000 meters, covering entire regions, such as the Arctic tundra, or a single, isolated spot, such as a mountaintop of alpine permafrost.
- Permafrost covers large regions of the Earth. Almost a quarter of the land area in the Northern Hemisphere has permafrost underneath.
- It occurs in 85 percent of Alaska and 55 percent of Russia and Canada, and covers probably all of Antarctica.
- What Is Permafrost Made Of?
- Permafrost is made of a combination of soil, rocks, and sand that are held together by ice.
- The soil and ice in permafrost stay frozen all year long.
- Although the ground is frozen, permafrost regions can be snow-free in summer.
- Near the surface, permafrost soils also contain large quantities of organic carbon—a material leftover from dead plants that couldn’t decompose, or rot away due to the cold.
- Lower permafrost layers contain soils made mostly of minerals.
- Permafrost loss, also known as permafrost thaw, is the progressive loss of ground ice in permafrost, usually due to input of heat.
- A layer of soil on top of permafrost does not stay frozen all year. This layer, called the active layer, thaws during the warm summer months and freezes again in the fall.
- In colder regions, the ground rarely thaws—even in the summer. There, the active layer is very thin—only 4 to 6 inches (10 to 15 centimeters).
- A thawing permafrost layer can lead to severe impacts on people and the environment.
- When permafrost melts, it raises water levels in Earth’s oceans.
- Melting permafrost and warming global temperatures have a positive feedback loop.
- Organic matter currently frozen in the permafrost will start to decompose when the ground thaws, resulting in the emission of methane and carbon dioxide into the atmosphere.
- As ice-filled permafrost thaws, it can turn into a muddy slurry that cannot support the weight of the soil and vegetation above it.
- Infrastructure such as roads, buildings, and pipes could be damaged as permafrost thaws.
- Melting permafrost also releases heavy metals, such as mercury, and other toxins.
- As it melts, the contaminated permafrost can pollute water sources for local people.
- It is even possible that thawing permafrost may release dormant, disease-causing microbes that are harmful to animals and humans.
Hence option a is the correct answer.

Question 6 of 10
6. Question
1 pointsConsider the following statements regarding Swyer Syndrome:
- It is a rare genetic condition where individuals have one X and one Y chromosome but develops female reproductive structures.
- Its symptoms are visible during childhood.
Which of the statements given above is/are correct?
Correct
Answer: a
Explanation:
Swyer syndrome is a rare condition which is estimated to occur in about one in 80,000 people.
About Swyer Syndrome:
- It is a rare difference of sex development, medically known as 46, XY complete gonadal dysgenesis.
- It is a rare genetic condition where individuals have one X and one Y chromosome in each cell (typically associated with males) but develop female reproductive structures.
- It is characterized by the failure of the sex glands (i.e., testicles or ovaries) to develop.
- It results from disruption of the genetic pathway involved in testicular development during early embryonic development.
- This syndrome is one of many “Disorders of Sex Development”, or DSDs.
- People with Swyer syndrome are genetically male but phenotypically female, meaning they have a female appearance and female external genitalia.
- Symptoms:
- Swyer syndrome may not be apparent during childhood and often comes to light during adolescence, when puberty does not progress normally.
- One of the most characteristic signs is primary amenorrhoea, meaning that menstruation does not begin.
- Treatment:
- There is currently no treatment that can change the 46, XY chromosome pattern or turn the streak gonads into functioning ovaries.
- However, the effects of Swyer syndrome can be effectively managed through hormone replacement therapy.
Hence only statement 1 is correct.

- It is radio telescope located in Hanle, Ladakh.
- It was built to map the distribution of hydrogen gas in the early universe.
- It consists of parabolic radio antennas that collect radio waves in the 400 to 800 MHz range.
How many of the above statements are correct?
Correct
Answer: b
Explanation:
An international team, including researchers from the Raman Research Institute (RRI) in Bengaluru, has detected the faint radio glow of hydrogen from 9 billion years ago by using CHIME radio telescope.
About CHIME Telescope:
- The CHIME (Canadian Hydrogen Intensity Mapping Experiment) is a radio telescope located in British Columbia, Canada which was built in 2017.
- Focus: It was built to map the distribution of hydrogen gas in the early universe.
- It is capable of mapping the sky with unprecedented sensitivity and speed.
- It delivers a snapshot of what our sky looks like at radio wavelengths every day.
- Components:
- CHIME comprises four massive parabolic radio antennas that collect radio waves in the 400 to 800 MHz range.
- It has no moving parts and instead uses signal processing techniques to combine the information from over a thousand antennas to focus and point the telescope digitally.
- The telescope receives radio signals each day from half of the sky as the Earth rotates.
- CHIME focuses incoming signals using a correlator—a powerful digital signaling processor that can work through huge amounts of data, at a rate of about 7 terabits per second.
- It has capability to detect and study Fast Radio Bursts (FRBs), transient flashes of radio waves originating from distant galaxies.
Hence only statements 2 and 3 are correct.
