BPSC 70th CCE Prelims General Studies · Question 51 of 143

Correct — D, 4 1 2 3. Read the pairing as Vaishali – floriculture, Bhagalpur – silk textile, Jamui – gold, Madhepura – rail rolling stock. Three of those legs are firm. Bhagalpur is Bihar's silk town, known nationally for Bhagalpuri and tussar silk, and the b–1 pairing is the least disputable link in the whole set; every other option breaks it, which is why fixing Bhagalpur alone leaves only option (d) standing. Jamui is where Bihar's gold lies, in the Sono belt of the district, and Jamui is the answer BPSC's own published key gives for the same pairing on the 71st, while our derived answer for the 69th agrees — so c–2 is corroborated once by the Commission and once by us, as well as by the geology. Madhepura hosts the only rail rolling-stock plant among these four districts: the Electric Locomotive Factory, a joint venture in which Alstom holds 74 per cent and the Ministry of Railways 26 per cent, incorporated on 20 November 2015, with manufacturing starting on 11 October 2017 on a 250-acre site, building the 12,000 horsepower WAG-12 electric freight locomotive under a contract for 800 units over eleven years. That leaves Vaishali with floriculture, and honesty requires saying that this last leg is reached by elimination rather than by confirmation — Vaishali's headquarters, Hajipur, is far better known for its bananas than for its flowers, and no primary source has been found describing floriculture as the district's signature activity. Since the other three legs are secure and only option (d) accommodates all three, the answer stands regardless.

• (a)3 4 1 2 — Sends the rail plant to Vaishali and silk to Jamui, and pairs Bhagalpur with floriculture. It breaks the Bhagalpur–silk link, which is the one association in this question that can be treated as certain, so it can be discarded the moment you check that single leg.
• (b)2 3 4 1 — Gives gold to Vaishali in the Gangetic plain, the rail factory to Bhagalpur, floriculture to Jamui and silk to Madhepura. Every leg is wrong. Gold in Bihar is a hard-rock occurrence in the southern uplands, not something the alluvial districts of the north hold.
• (c)1 2 3 4 — The straight-down 1-2-3-4 sequence, which is always worth suspecting on a matching question. It attaches silk to Vaishali, gold to Bhagalpur, the rail factory to Jamui and floriculture to Madhepura — again destroying the Bhagalpur–silk pairing that anchors the item.

Bihar's industrial geography is thin but distinctive, and BPSC tests it as a set of district-to-activity associations that repeat from paper to paper. Bhagalpur, on the south bank of the Ganga in eastern Bihar, is the silk centre: its handloom weavers work tussar and mulberry silk, and 'Bhagalpuri silk' is the state's best-known textile identity. Jamui, in the hill country of south Bihar against the Jharkhand border, sits on the same Precambrian rocks as the Chota Nagpur mineral belt, and its Sono area holds the state's gold — an occurrence in hard rock, which is why it belongs to the southern uplands and not to the alluvium of north Bihar. Madhepura, in the Kosi region of north Bihar, was chosen in the 2010s for a greenfield electric locomotive plant, one of the two big railway manufacturing investments made in the state in that decade. Vaishali, with its headquarters at Hajipur, is an agricultural and horticultural district of the north Gangetic plain. Note the imprecision in the list: what stands at Madhepura is a locomotive factory, not a coach factory — India's rail coach factories are at Kapurthala, Perambur and Raebareli.

Matching questions are solved by anchors, and here the anchor is Bhagalpur with silk. It is the strongest single association in Bihar's economic geography, and only option (d) preserves it, so a candidate who knows nothing else can finish the question in one step. Add Jamui with gold as a second anchor and the answer is doubly confirmed. The right way to handle the two weaker legs is to notice that they cannot change the outcome. 'Rail coach factory' is loose wording — the Madhepura plant builds locomotives, and the coach factories are elsewhere — but among Vaishali, Bhagalpur, Jamui and Madhepura only one district has any rail manufacturing at all, so the intended pairing is unambiguous even though the label is inexact. Floriculture with Vaishali is the leg that cannot be independently confirmed, and it is also the leg you never need: once three matches are fixed, the fourth follows by elimination in a one-to-one match. That is the general lesson — in a four-by-four match you only ever have to be sure of three.

• Bhagalpur is Bihar's silk centre, associated with Bhagalpuri and tussar silk weaving; the b–1 pairing is the anchor that eliminates options (a), (b) and (c)
• Jamui district holds Bihar's gold, in the Sono belt of the southern uplands; BPSC's published key for the 71st gives Jamui as the gold district, and the 69th's derived answer agrees (the 69th has no official key)
• The Electric Locomotive Factory at Madhepura is a joint venture with Alstom holding 74 per cent and the Ministry of Railways 26 per cent, incorporated on 20 November 2015, with production starting on 11 October 2017 on a 250-acre site
• It builds the WAG-12 electric freight locomotive of 12,000 horsepower, under an order for 800 units over eleven years; the first was dedicated in April 2018 and about 300 had been produced by March 2023
• India's rail coach factories are at Kapurthala in Punjab, Perambur in Chennai and Raebareli in Uttar Pradesh — so the List – II label 'rail coach factory' is loose, and the Madhepura plant is a locomotive works

• Reading 'rail coach factory' literally and looking for a coach plant; the Madhepura unit builds electric locomotives, and India's coach factories are outside Bihar
• Marking the straight 1-2-3-4 option, which matching questions offer precisely because it is the sequence an unprepared candidate falls into
• Expecting gold in a north Bihar district; Bihar's gold occurrence is in the hard rock of the southern uplands, in Jamui

BPSC asks Bihar's economic geography as a four-by-four district-to-activity match, and it recycles the individual legs as standalone single-answer questions in adjacent years — Jamui and gold has now appeared in three consecutive editions in one form or another. UPSC asks the same skill at national scale, matching minerals to their typical areas of occurrence or railway units to their locations, and prefers the 'which pair is NOT correctly matched' format.

  The Electric Locomotive Factory at Madhepura in Bihar is a joint venture between Indian Railways and which company ?

  • (a)Siemens
  • (b)Alstom
  • (c)General Electric
  • (d)Bombardier

  Answer(b) Alstom — which holds 74 per cent of the joint venture against the Ministry of Railways' 26 per cent, and builds the 12,000 horsepower WAG-12 freight locomotive there.

• practice — not a real PYQ

  Bhagalpur in Bihar is best known for the production of which of the following ?

  • (a)Silk textiles
  • (b)Cement
  • (c)Aluminium
  • (d)Jute goods

  Answer(a) Silk textiles — Bhagalpuri and tussar silk, which is the association that anchors the whole matching question.
