Concept: Khelo India supports grassroots talent through Khelo India Athletes (KIAs) and its training centres and academies.

1. As of February 2025, the government reported that 1424 athletes trained under Khelo India had set international records.
2. Khelo India was launched in 2017–18 by the Ministry of Youth Affairs and Sports to build a strong sports culture.

Yaad rakhein: Khelo India record-setters (Feb 2025) = 1424.

Answer: (A) 1424

Concept: Brønsted–Lowry theory: the stronger an acid, the weaker its conjugate base, and vice versa.

1. HF ionises only partly: $\text{HF}\rightleftharpoons {\text{H}}^{+}+{\text{F}}^{-}$, so it is a weak acid.
2. Its conjugate base ${\text{F}}^{-}$ therefore accepts protons to a limited extent – it is a weak base (stronger than ${\text{Cl}}^{-}$, but still weak).
3. ${\text{F}}^{-}$ cannot be an acid or neutral; it is a proton acceptor.

Yaad rakhein: Strong acid → very weak conjugate base; weak acid → weak conjugate base.

Answer: (C) It is a weak base.

Concept: The Defence Acquisition Council (DAC) approves capital acquisition proposals, with priority to "Buy (Indian-IDDM)".

1. In 2024, the Indian government approved defence acquisitions worth about US$17.3 billion.
2. About 99% of these were to be sourced from domestic suppliers, in line with Aatmanirbhar Bharat in defence.

Yaad rakhein: 2024 defence approvals: $17.3 billion, 99% Made-in-India.

Answer: (C) 99%

Concept: Concurrent access to a shared file is controlled by file locking (a synchronisation mechanism).

1. A lock (shared/read or exclusive/write) lets only safe combinations of processes use a file at once, preventing corrupted or lost updates.
2. Paging and virtual memory manage main memory, not file consistency.
3. Scheduling decides which process gets the CPU; it does not protect file data.

Yaad rakhein: Many writers, one file → lock it.

Answer: (A) File locking mechanisms

Concept: Between the Lesser Himalaya (Himachal) and the Shiwaliks lie flat longitudinal valleys called Duns (Doons).

1. Examples: Dehradun, Kotli Dun and Patli Dun.
2. Doab = land between two rivers; Khadar = new alluvium of floodplains; Meanders = river loops.

Yaad rakhein: Dehradun itself is a Dun valley.

Answer: (A) Duns

Concept: The Economic Survey 2024-25 discussed the heavy FPI selling in Indian equities in late 2024.

1. It cited slowing corporate earnings growth and high (stretched) valuations of Indian stocks.
2. It also pointed to global uncertainty – rising geopolitical tensions and a strong US dollar/high US yields – pulling funds away.
3. Hence all three factors apply.

Yaad rakhein: FPI exit = weak earnings + costly valuations + global risk.

Answer: (D) All 1, 2, and 3

Concept: The Bullets button (Home tab → Paragraph group) formats selected paragraphs as an unordered list.

1. Each selected paragraph gets a bullet symbol (•) at its start.
2. The Numbering button (next to it) creates a numbered list – the tempting wrong option.
3. Alignment and font size are separate buttons.

Yaad rakhein: Bullets = unordered list; Numbering = ordered list.

Answer: (C) The selected text is converted into a bulleted list

Concept: The 2024 ICC Women's T20 World Cup was played in the UAE (shifted from Bangladesh) in October 2024.

1. New Zealand beat South Africa by 32 runs in the final at Dubai.
2. It was New Zealand's first Women's T20 World Cup title; Amelia Kerr was Player of the Match and Player of the Tournament.

1. The 24th edition of WSDS was held in New Delhi from 5 to 7 March 2025.
2. Its theme was "Partnerships for Accelerating Sustainable Development and Climate Solutions".

Yaad rakhein: WSDS 2025 → 24th edition (2024 was the 23rd).

Answer: (B) 24^th

Concept: Diffusion models generate images by learning to remove noise step by step from random noise.

1. In 2025, researchers at the Indian Institute of Science (IISc), Bengaluru used a diffusion model to create realistic synthetic images.
2. These images enlarged the training data and improved object detection, especially where real labelled images are scarce.
3. GANs also generate images, but the IISc work used a diffusion-based approach.

Yaad rakhein: Noise → clean image = Diffusion.

Answer: (A) Diffusion Model

Concept: The Charter Act of 1853 was the last Charter Act of the East India Company.

1. It separated, for the first time, the legislative and executive functions of the Governor-General's Council.
2. It added six legislative members, creating a separate Central Legislative Council (a "mini-Parliament").
3. It also introduced open competition for the Civil Services. (1833 only made the Governor-General of Bengal the Governor-General of India.)

Yaad rakhein: 1853 = Legislative split + ICS open exam.

Answer: (C) Charter Act of 1853

Concept: The Aravalli range runs SW–NE across Rajasthan.

1. The Great Indian (Thar) Desert lies to the west and north-west of the Aravallis.
2. The Aravallis lie parallel to the moist SW monsoon winds and cannot stop them, so the region to their north-west stays dry.
3. East of the Aravallis lie the Mewar/Hadoti uplands, not desert.

Yaad rakhein: Aravalli ke paar (North-West) = Thar.

Answer: (A) North-West

Concept: When you create a folder in Windows (right-click → New → Folder, or Ctrl+Shift+N), it is named automatically.

1. The default name is "New folder".
2. Further folders become "New folder (2)", "New folder (3)" and so on.
3. "Untitled Folder" is the default on macOS/Linux, not Windows.

Yaad rakhein: Windows: New folder; Mac: untitled folder.

Answer: (B) New Folder

Concept: The Scheme of Assistance to National Sports Federations (NSFs) funds training and participation of Indian teams in international events.

1. In January 2025, the Sports Ministry decided, for the first time, to give financial assistance under this scheme to the Indian contingent for the 9th Asian Winter Games, Harbin (China), February 2025.
2. Earlier, winter-sport contingents had to arrange funding themselves.
3. TOPS supports individual elite athletes, not a whole contingent.

Yaad rakhein: Contingent funding → Assistance to NSFs.

Answer: (A) Assistance to National Sports Federations

Concept: NCERT's assessment of the LPG reforms of 1991.

1. Agricultural growth slowed after reforms, and public investment in agriculture (irrigation, power, roads, research) actually declined – so statement C is NOT correct.
2. Industrial growth also stayed sluggish; its GDP share did not rise enormously (B is correct).
3. Trade and investment were liberalised to make industry internationally competitive (D is correct).

Yaad rakhein: Reforms neglected agriculture – public investment fell, not rose.

Answer: (C) The 1991 reforms have caused a huge increase in public investment in the agriculture sector and increased its share in India's GDP.

Concept: In 1991 India faced a balance of payments crisis with foreign exchange reserves enough for only about two weeks of imports.

1. India took a loan from the International Monetary Fund (IMF) (and the World Bank).
2. In return it accepted structural adjustment conditions – the basis of the New Economic Policy (LPG).
3. The WTO was formed only in 1995; WHO and UN do not provide BoP support.

Yaad rakhein: BoP crisis → IMF; development loans → World Bank.

Answer: (B) International Monetary Fund

Concept: Salvarsan (arsphenamine, "compound 606"), the first effective drug for syphilis, was found in 1909 in Paul Ehrlich’s laboratory with Sahachiro Hata and came into use in 1910.

1. Salvarsan itself never received a Nobel Prize.
2. Ehrlich’s Nobel Prize in Physiology or Medicine was in 1908 (shared with Ilya Mechnikov) for work on immunity, a year before salvarsan was discovered, so (B) is not a prize for salvarsan.
3. 1905 (Robert Koch, tuberculosis) and 1929 (vitamins) were for other work, and no medicine prize was given in 1915.
4. The premise is false, so no option is correct.

Note: Ehrlich: Nobel 1908 for immunity; salvarsan 1909–10 is his "magic bullet" but not a Nobel subject. In the exam, every candidate gets full marks (bonus) for such a question.

Answer: Bonus – no option is correct as printed; full marks to all.

Concept: Warli is a tribal art of the Warli community of the Thane–Palghar region, Maharashtra.

1. The mud wall is first coated with a mixture of cow dung and water (often with red earth); this background preparation is called "Lipane".
2. Figures are then painted in white made from rice paste using a bamboo stick.
3. Rangoli is a floor design, not a wall-preparation step.

Yaad rakhein: Lipane = "lipna" – smearing the wall with cow dung.

Answer: (D) Lipane

Concept: The Urban Infrastructure Development Fund (UIDF) was announced in Union Budget 2023-24 on the lines of RIDF.

1. It is created through use of the priority sector lending (PSL) shortfall of banks.
2. It is managed by the National Housing Bank, about ₹10,000 crore a year, to fund urban infrastructure in Tier-2 and Tier-3 cities.
3. Rural infrastructure is financed by RIDF (NABARD), not UIDF.

Yaad rakhein: RIDF – rural – NABARD; UIDF – urban – NHB; both from PSL shortfall.

Answer: (C) To utilise priority sector lending shortfall

Concept: In humans, Plasmodium multiplies first in liver cells and then inside red blood cells (erythrocytic cycle).

1. Merozoites enter RBCs, mature and divide asexually (schizogony).
2. The RBCs rupture, releasing new merozoites and the toxin haemozoin – this causes the cycle of chills and high fever.
3. Liver multiplication does not burst RBCs; sexual reproduction happens in the mosquito gut, not in erythrocytes.

Yaad rakhein: RBC burst = merozoites multiply inside RBC = fever every 48 hours (vivax).

Answer: (A) Maturation and multiplication of merozoites inside the RBCs
