Match List – I with List – II and select the correct answer from the code given below the lists. List – I (Revolution) A. Golden Revolution B. Grey Revolution C. Yellow Revolution D. Black Revolution List – II (Related with) 1. Oil seed production 2. Horticulture and Honey 3. Petroleum production 4. Fertilizers Code :
- (a)A-2, B-3, C-4, D-1
- (b)A-4, B-2, C-1, D-3
- (c)A-2, B-4, C-1, D-3
- (d)A-1, B-2, C-3, D-4
Correct — C, A-2, B-4, C-1, D-3. The commission pairs the Golden Revolution with horticulture and honey, the Grey Revolution with fertilizers, the Yellow Revolution with oilseed production, and the Black Revolution with petroleum. Two of those four are firm and two are not, and it is worth being straight about which. Yellow for oilseeds is settled — it belongs to the Technology Mission on Oilseeds of 1986 and no compilation disputes it — and Golden for horticulture is the standard usage, with honey commonly attached to it. Grey and Black are the unstable pair. This colour vocabulary has no single government source behind it; it is a preparation-book convention, and the books disagree. Grey is given as fertilizers in most Indian compilations but as wool in others, and Black is given as petroleum in most but as coal in some. This card therefore reports the key's pairings as the convention the commission used, and does not present the Grey and Black pairings as settled fact.
- (a)A-2, B-3, C-4, D-1 — It opens correctly with Golden for horticulture and honey, then breaks on the one pairing nobody disputes: it gives the Yellow Revolution to fertilizers and pushes oilseeds onto Black. Yellow means oilseeds, so this option fails on its third pair regardless of what one thinks about Grey.
- (b)A-4, B-2, C-1, D-3 — The near miss, and the one to study. It has Yellow with oilseeds and Black with petroleum exactly as the key does, but swaps the first pair — Golden becomes fertilizers and Grey becomes horticulture and honey. Golden is the horticulture revolution in every compilation, so the swap is the error.
- (d)A-1, B-2, C-3, D-4 — The straight 1-2-3-4 order. It makes Golden the oilseed revolution and Yellow the petroleum one, both of which reverse the standard usage. As in most match-the-list items, the serial sequence is a decoy rather than an answer.
Indian preparation literature labels sectoral production drives by colour, and the exams draw on that vocabulary even though it is not an official taxonomy. The ones that are stable across sources: Green for foodgrains, the wheat and rice transformation from the mid-1960s; White for milk, meaning Operation Flood from 1970 under Verghese Kurien; Yellow for oilseeds, the Technology Mission on Oilseeds of 1986; Blue for fisheries; Golden for horticulture, with fruit, honey and beekeeping usually folded in; Silver for eggs and poultry; Round for potato; Brown for leather. Golden Fibre Revolution is a separate label and means jute, not horticulture — a distinction worth keeping because the two names look alike.
The reasoning route here does not require you to settle the disputed colours at all, which is the useful thing about this question. Anchor on the one pairing that is beyond argument: Yellow means oilseeds. Only options (b) and (c) place C with 1, so (a) and (d) go straight out. Then anchor on the second-firmest: Golden means horticulture. Option (b) gives Golden to fertilizers, so it falls, and (c) is left. That is the whole solution, and it never asks you to decide whether Grey is fertilizer or wool, or whether Black is petroleum or coal. Learn the settled colours cold and use them as anchors; do not try to memorise the whole disputed spectrum, because the sources you would memorise from do not agree with each other.
- As keyed by the commission: Golden – horticulture and honey; Grey – fertilizers; Yellow – oilseed production; Black – petroleum production
- Yellow for oilseeds is the settled pairing, associated with the Technology Mission on Oilseeds launched in 1986
- Grey and Black are genuinely disputed in Indian compilations — Grey appears as fertilizers in most and as wool in others; Black as petroleum in most and as coal in some
- This colour vocabulary has no single official government source; it is an exam convention, not a scheme classification
- Undisputed elsewhere in the spectrum: Green – foodgrains; White – milk (Operation Flood, 1970); Blue – fisheries; Silver – eggs and poultry
- 'Golden Fibre Revolution' is a separate label and refers to jute, not to horticulture
Together these give A-2, B-4, C-1, D-3, which is option (c). The two highlighted rows are the ones no source disputes, and they are enough on their own: fixing Yellow to oilseeds removes options (a) and (d), and fixing Golden to horticulture removes (b). The unhighlighted rows are reported as the commission keyed them, not asserted as settled.
- Treating the whole colour spectrum as official; only a handful of the pairings are stable, and Grey and Black are not among them
- Confusing the Golden Revolution (horticulture) with the Golden Fibre Revolution (jute)
- Trying to solve the question through the disputed colours instead of anchoring on Yellow and Golden, which settles it without them
UPPSC asks the colour revolutions as a four-way match and expects the prep-book convention rather than a scheme document. UPSC has stayed away from the colour labels almost entirely and asks the underlying programmes instead — who led the Green Revolution, what Operation Flood did, what the fisheries or horticulture missions cover — which is the more durable way to hold the material.

The White Revolution in India is associated with the increased production of
- (a)Foodgrains
- (b)Milk
- (c)Fish
- (d)Eggs
Answer(b) Milk — the White Revolution was driven by Operation Flood, launched in 1970 and led by Verghese Kurien on the Anand cooperative pattern, which made India the world's largest milk producer.

The Blue Revolution in India refers to development in the field of
- (a)Fisheries and aquaculture
- (b)Drinking water supply
- (c)Irrigation canals
- (d)Solar energy
Answer(a) Fisheries and aquaculture — Blue is one of the stable colour labels, covering inland and marine fisheries development; drinking water and irrigation carry no colour label of their own.
