Concept: The Government of India Act, 1919 (Montagu–Chelmsford Reforms) introduced dyarchy in the provinces, dividing provincial subjects into Transferred and Reserved.

1. Transferred subjects were run by ministers responsible to the legislature: local self-government, education, health, agriculture, public works.
2. Reserved subjects stayed with the Governor and his Executive Council: police, justice, land revenue, irrigation, finance.
3. So Police was a Reserved subject, not a Transferred one.

Yaad rakhein: Law-and-order and money (police, justice, finance, land revenue) were 'reserved' by the British; welfare subjects were 'transferred'.

Answer: (B) Police

Concept: Across a period, nuclear charge increases while electrons enter the same shell, so the nucleus holds electrons more tightly.

1. Atomic radius decreases from left to right.
2. Metallic character decreases (elements lose electrons less easily).
3. Ionisation enthalpy – the energy to remove an electron – therefore increases across a period (with minor exceptions like N/O).

Yaad rakhein: Left → right: size ↓, metallic ↓, ionisation enthalpy ↑, electronegativity ↑.

Answer: (B) Ionisation enthalpy

Concept: The Chairman of the UPSC is appointed by the President under Article 316.

1. Former Defence Secretary Ajay Kumar was appointed UPSC Chairman in May 2025.
2. He succeeded Preeti Sudan, whose tenure ended in April 2025.

Concept: INCOIS (Hyderabad, under the Ministry of Earth Sciences) provides ocean information and early-warning services.

1. In 2025 INCOIS launched a submarine-cable-based ocean observation system that carries sensors on the sea floor and sends real-time data.
2. Its aim is to strengthen long-term, continuous observations of the Indian Ocean (for tsunami warning, climate and ocean studies) – not internet, tourism or defence.

Yaad rakhein: INCOIS = Ocean INFORMATION – so its cable is for ocean observation.

Answer: (D) Enhance long-term Indian Ocean observations

Concept: pH is a logarithmic scale: $\text{pH}=-\log [{\text{H}}^{+}]$, so each fall of 1 in pH means 10 times more ${\text{H}}^{+}$ ions.

1. pH 2: $[{\text{H}}^{+}]={10}^{-2}$; pH 4: $[{\text{H}}^{+}]={10}^{-4}$.
2. Ratio $=\frac{{10}^{-2}}{{10}^{-4}}={10}^2=100$.
3. So the pH 2 solution is 100 times more acidic.

Trick: Difference in pH = $n$ ⇒ acidity differs by ${10}^n$; here ${10}^2=100$.

Answer: (C) 100 times

Concept: The Green Revolution (from the mid-1960s) used high-yielding variety (HYV) seeds, chemical fertilisers, pesticides and assured irrigation.

1. It sharply raised the output of wheat and rice, ending India's dependence on food imports (PL-480).
2. Thus India became self-sufficient in food grains; oilseeds needed a separate 'Yellow Revolution'.

Yaad rakhein: Green = grains (wheat, rice); Yellow = oilseeds; White = milk.

Answer: (D) food grains

Concept: The Law of Definite Proportions says a compound always contains the same elements in the same fixed ratio by mass.

1. Dalton's postulate: atoms combine in simple whole-number ratios to form compounds.
2. If a compound always has, e.g., 2 H atoms per O atom, its mass ratio is fixed – this explains definite proportions.
3. 'Indivisible atoms' explains conservation of mass, not definite proportions.

Yaad rakhein: Fixed whole-number ratio of atoms ⇒ fixed mass ratio.

Answer: (D) Atoms combine in simple whole-number ratios to form compounds.

Concept: Radar imaging satellites (synthetic aperture radar, SAR) can image the Earth by day and night and through clouds – 'all-weather' observation.

1. EOS-09 is a C-band SAR earth-observation satellite launched on PSLV-C61 on 18 May 2025 to boost all-weather, day-and-night imaging (the mission could not reach orbit due to a third-stage problem). EOS-09 is the mission's official name.
2. INSAT-3DS is a meteorological satellite (2024) and Cartosat-3 an optical satellite (2019).

Yaad rakhein: SAR = sees through clouds and darkness; May 2025 → EOS-09 on PSLV-C61.

Answer: (D) EOS-09

Concept: The International Booker Prize is given jointly to the author and the translator of a book translated into English.

1. Banu Mushtaq's Kannada short-story collection 'Heart Lamp' won it in May 2025.

Yaad rakhein: Heart Lamp: Banu Mushtaq (author) + Deepa Bhasthi (translator).

Answer: (B) Deepa Bhasthi

Concept: Part XI (Articles 245–255) deals with legislative relations between the Union and the States.

1. Article 245: Parliament may make laws for the whole or any part of India; a State Legislature for the whole or any part of the State.
2. Art 249 – Parliament on State List in national interest (Rajya Sabha resolution); Art 250 – during emergency; Art 256 – obligation of States (administrative relations).

Yaad rakhein: 245 = territorial extent of laws; 246 = subject-matter (Seventh Schedule lists).

Answer: (B) Article 245

Concept: The 1991 reforms (Liberalisation, Privatisation, Globalisation – LPG) opened the economy to private and foreign investment.

1. Growth was led by the services sector – IT, telecom, banking, trade – and private firms expanded.
2. So employment opportunities increased, especially in private and service sectors; agriculture's share in jobs actually fell.

Yaad rakhein: LPG ⇒ boom in services & private sector.

Answer: (B) Increased, especially in private and service sectors

Concept: The Great Indian (Thar) Desert lies in north-western India, west of the Aravalli range.

1. About 60% or more of the Thar lies in Rajasthan (Jaisalmer, Barmer, Bikaner, Jodhpur).
