The Current Affairs questions are based on sources like ‘The Hindu’, ‘Indian Express’ and ‘PIB’, which are very important sources for UPSC Prelims Exam. The questions are focused on both the concepts and facts. The topics covered here are generally different from what is being covered under ‘Daily Current Affairs/Daily News Analysis (DNA) and Daily Static Quiz’ to avoid duplication. The questions would be published from Monday to Saturday before 2 PM. One should not spend more than 10 minutes on this initiative.
Gear up and Make the Best Use of this initiative.
Do remember that, “the difference between Ordinary and EXTRA-Ordinary is PRACTICE!!”

Consider the following with respect to ‘Bubble Baby Syndrome’
Select the correct statement(s)
Solution (c)
Statement Analysis:
| Statement 1 | Statement 2 | Statement 3 |
| Correct | Incorrect | Correct |
| ‘Bubble baby syndrome,’ known medically as Severe Combined Immunodeficiency (SCID) is very rare genetic disorder that causes life-threatening problems with the immune system.
It is a type of primary immune deficiency. |
Autosomal Recessive: This is the most common pattern, affecting around 70% of SCID cases. In this scenario, a child inherits a faulty copy of the same gene from both parents, who may not exhibit any symptoms themselves if they carry only one faulty copy. This means the risk of SCID for subsequent children born to the same parents is 25% with each pregnancy. | Treatment:
The most common treatment is a stem cell transplant (also called a bone marrow transplant). This means the child receives stem cells from a donor. The hope is that these new cells will rebuild the child’s immune system. |
Context: A two-month-old girl with bubble baby syndrome underwent bone marrow transplant (BMT) in Mumbai recently.

With reference to ‘Pangolins’ consider the following statements
Select the INCORRECT statement(s)
Solution (c)
| Statement 1 | Statement 2 |
| Incorrect | Incorrect |
| Pangolins, also known as scaly anteaters, are the only known mammals with large keratin scales covering their skin.
Of the eight species found worldwide (four each in Asia and Africa), two are found in India: the Indian Pangolin (Manis crassicaudata) and the Chinese Pangolin (Manis pentadactyla). About Indian Pangolin The Indian pangolin, also called the thick-tailed pangolin, is native to the Indian subcontinent. They are one of the most trafficked mammals in the world, despite an international ban on their trade. Distribution: It lives in India (south of the Himalayas), Bangladesh, Southern Nepal, Sri Lanka, and small parts of Pakistan.
Conservation status: IUCN Red List: Endangered Wildlife (Protection) Act, 1972: Schedule I CITES: Appendix I |
The Chinese pangolin, with its armour of shimmering scales and specialized ant-eating tongue, inhabits a diverse but increasingly fragmented array of ecosystems. Understanding their preferred homes and the threats they face is crucial for their conservation.
Conservation Status: · Critically Endangered: Sadly, the Chinese pangolin is listed as Critically Endangered by the IUCN Red List. This means they face an extremely high risk of extinction in the wild due to multiple threats. |
Context: The pangolin conservation project launched to protect pangolins has succeeded at Pench Tiger Reserve and Satpura Tiger Reserve, as the mammals have started to breed there.

With reference to ‘KH-22 missile’ consider the following statements
How many statement(s) given above are correct
Solution (a)
Statement Analysis:
| Statement 1 | Statement 2 | Statement 3 |
| Correct | Incorrect | Incorrect |
| It is a Soviet-era long-range airborne supersonic cruise missile.
Armed with a nuclear or highly explosive fragmenting cumulative warhead, it was initially designed to destroy aircraft carriers and other large warships, or even groups of such carriers
The missiles and the aircraft were modernized as part of the so-called “Kh-22 special air-to-surface missile complex.”. |
It is long-range airborne supersonic cruise missile
Capabilities: Long Range: Boasting a range of around 1,000 kilometers, the Kh-22 can strike targets far out at sea, posing a significant threat to naval vessels. Supersonic Speed: Traveling at Mach 3, the missile is incredibly fast, making interception challenging for most defense systems. High Payload: Capable of carrying a conventional or nuclear warhead, the Kh-22’s destructive potential is immense. |
The Kh-22 employs a liquid-fuel rocket engine, specifically a Tumansky RD-33K engine. This type of engine provides the necessary thrust for the missile to reach its high speeds and long range. |
Context: Recently, KH-22 missile was used in Russia-Ukraine war.
