Assertion (A) is true: Industries using raw materials that lose weight during processing (like sugar cane or iron ore) locate near the source to avoid transporting waste material.


Reason (R) is true: Transporting heavy, bulky, weight-losing raw materials over long distances increases transportation costs significantly. Locating near the source minimizes this cost, thereby reducing the final cost of production.


Logical Link: The reason for locating near the source (A) is precisely to cut down transport costs and thus reduce the product cost (R). Therefore, (R) explains (A).
Quick Tip: Weight-losing raw material = High Transport Cost. Location Strategy = Minimize Distance = Minimize Cost.

Statement I is correct: Gathering is practiced in high latitude zones (very cold) and low latitude zones (very hot/humid forests), which are harsh climates.


Statement II is correct: Commercial gathering (collecting valuable plants, leaves, bark) has become market-oriented in modern times.


Statement III is incorrect: Denmark is a classical example of Cooperative Farming (Dairy), not gathering. Gathering is associated with less developed economies.


Statement IV is correct: It is the oldest economic activity practiced by primitive societies.


Therefore, the correct combination is I, II, and IV.
Quick Tip: Denmark = Dairy/Cooperative Farming. Gathering = Amazon/Congo/Tundra.

(A) is incorrect because retail trading happens in both rural (periodic markets, village stores) and urban areas.


(B) is incorrect; Wholesale traders typically act as collection and distribution centers connecting manufacturers to retailers.


(C) is correct; This is the standard definition of retail trading—selling goods in small quantities directly to the final consumer for personal use.


(D) is incorrect; This function (directing manufacturing specs) is more characteristic of large wholesale chains or big commercial buyers, not typical small retailers.
Quick Tip: Retail = Direct to Consumer. Wholesale = Business to Business (Retailer).

The Panama Canal cuts across the Isthmus of Panama, connecting the Atlantic Ocean and the Pacific Ocean.


(A) Yokohama (Japan) and Vancouver (Canada) are both in the Pacific; no canal needed.


(B) Auckland and Honolulu are both in the Pacific; no canal needed.


(C) San Francisco is on the US West Coast (Pacific) and New York is on the US East Coast (Atlantic). The Panama Canal shortens this journey significantly by avoiding the route around South America (Cape Horn).

Quick Tip: Atal Tunnel = Rohtang Pass = Pir Panjal Range.

Assertion (A) is true: International trade allows countries to specialize and exchange goods, leading to mutual economic benefits (Comparative Advantage).


Reason (R) is true: The fundamental basis of trade is obtaining goods that a country cannot produce efficiently itself (needed items) from others.


Logical Link: Because trade allows countries to acquire what they need but lack (R), it results in a situation where all participating nations benefit by satisfying their demands (A). Thus, (R) explains why it is beneficial.
Quick Tip: Trade = Exchange of Surplus for Deficit = Mutual Benefit.

The Yamuna river in Delhi is severely polluted.


While agricultural runoff (pesticides/fertilizers) contributes to pollution in general, the specific and most massive source of pollution for the Yamuna in the Delhi stretch is the discharge of untreated domestic waste water (sewage) and industrial effluents from the city.


Flood water spreading is a natural event, not a primary continuous polluter.


Therefore, (B) is the main anthropogenic cause in the urban context of Delhi.
Quick Tip: Urban River Pollution = Domestic Sewage + Industrial Effluents.

Water-borne diseases are spread through the transmission of pathogens (bacteria, viruses, parasites) in contaminated water.


Diarrhoea, Hepatitis (specifically Hepatitis A and E), and Intestinal worms are classic examples of diseases caused by drinking polluted water or poor sanitation.


Asthma is a respiratory condition. Blood pressure is a lifestyle/genetic condition. Headache is a general symptom. These are not primarily transmitted through water.
Quick Tip: Common Water-borne diseases: Cholera, Typhoid, Diarrhoea, Hepatitis, Jaundice.

Migration factors are classified into Push (adverse conditions) and Pull (attractive conditions).


Push factors force people to leave rural areas:

I. Unemployment: Lack of work drives people out.

III. Economic backwardness: Poverty and lack of development.

IV. Lack of medical facilities: Poor infrastructure.


Factor II (Job opportunities) is a Pull factor that attracts people to urban areas, not a push factor.


Therefore, the correct set of Push Factors is I, III, and IV.
Quick Tip: Push = "Go away" (Negative/Problem). Pull = "Come here" (Positive/Attraction).

We need to identify reasons associated with the deterioration (degradation) of land quality.


I. Soil erosion and waterlogging: These are primary physical causes of land degradation.


II. Salinisation and alkalinisation: These are chemical degradation processes often caused by improper irrigation.


IV. Decline in land productivity: This is a direct consequence/manifestation of deterioration.


III. Rich land fertility: This describes high-quality land, which is the \textit{opposite of deterioration. Therefore, statement III is incorrect in this context.


Eliminating options containing III, we are left with (B).
Quick Tip: Elimination Strategy: "Rich fertility" is a positive trait. The question asks about "deterioration" (negative). Eliminate any option with III.

The Namami Gange Programme focuses on pollution abatement and conservation of the river Ganga.


(A) Monitoring industrial effluents is a key pillar to stop untreated waste from entering the river.


(D) is incorrect because the Ganga does not flow through Assam (the Brahmaputra does). Ganga Grams are developed in states along the Ganga banks.


(B) and (C) are general irrigation/water projects, not the specific primary objectives of the Namami Gange clean-up mission.
Quick Tip: Geography Fact: The River Ganga flows through Uttarakhand, UP, Bihar, West Bengal. Not Assam.

The passage explicitly states in the first sentence: ``There are many professionals who provide their services against payment of their fee.''


Therefore, a person avails these services by exchanging payments or fees.
Quick Tip: Source-based answer: Look for the "How" in the first line of the text.

Secondary Sector: It is related to the manufacturing, processing, and construction industries where tangible goods are produced (e.g., making steel, weaving cloth).


Tertiary Sector: As mentioned in the passage, it is related to the "service sector". It involves the provision of special skills, expertise, and knowledge (intangible services) rather than physical goods (e.g., teaching, medical treatment).
Quick Tip: Secondary = Factory/Goods. Tertiary = Skills/Services.

The relationship is interdependent:


Example 1: The Primary sector produces raw cotton (agriculture). The Secondary sector (textile industry) uses this cotton as a raw material to manufacture cloth.


Example 2: The Secondary sector manufactures tools and machinery (tractors, fertilizers). The Primary sector uses these inputs to increase agricultural production.
Quick Tip: Input-Output Link: Farm output \(\rightarrow\) Factory input. Factory output \(\rightarrow\) Farm tool.

Number of towns in 1941 = 2,250

Number of towns in 1991 = 4,689

Increase = \(4689 - 2250 = 2439\).
Quick Tip: Simple subtraction: Value(1991) - Value(1941).

Comparing the "% of Total Population" column:

1931-41: \(13.86 - 11.99 = 1.87\)

1941-51: \(17.29 - 13.86 = 3.43\)

1951-61: \(17.97 - 17.29 = 0.68\)

1961-71: \(19.91 - 17.97 = 1.94\)

The minimum increase of 0.68 percentage points occurred in 1951-1961.
Quick Tip: Look for the smallest jump in the percentage column. 17.29 to 17.97 is very small.

The "Decennial Growth (%)" column shows the rate at which the urban population grew.

It increased significantly from 19.12% (1931) to a peak of 41.42% (1951).
