Explanation
The correct answer is A, Red Sindhi. Red Sindhi is an indigenous Indian dairy breed of cattle, while the other three are Indian dog breeds.
Red Sindhi cattle take their name from the Sindh region and are reddish-brown, hardy and able to bear heat, which is why they have been used to improve milk yield in many tropical countries. Sahiwal, Gir, Tharparkar and Deoni are the other well-known indigenous milch breeds, while Amritmahal, Hallikar and Kangayam are draught breeds. Under the Rashtriya Gokul Mission the government works to conserve and develop such native breeds.
B is wrong: Chippiparai is a sight hound dog breed of Tamil Nadu. C is wrong: Kanni is also a dog breed from southern Tamil Nadu. D is wrong: Kombai is a Tamil Nadu hunting dog breed, not cattle.
Exam tip: Indigenous milch cattle - Red Sindhi, Sahiwal, Gir, Tharparkar, Deoni; Chippiparai, Kanni and Kombai are dog breeds.

View allIn which State/Union Territory is the Jog Waterfall located?
- A.Punjab
- B.Karnataka
- C.Jammu and Kashmir
- D.Ladakh
Show answer
Correct answer: B. Karnataka
Explanation
The correct answer is B, Karnataka. Jog Falls is in the Shivamogga district of Karnataka.
The Sharavathi river drops about 253 metres here in four separate streams known as Raja, Rani, Rocket and Roarer, which makes Jog one of the highest plunge waterfalls in India. It lies in the Western Ghats, is fed by the monsoon, and the Linganamakki dam upstream supplies the Mahatma Gandhi hydroelectric station, so the flow is strongest in the rains. The falls are also called Gersoppa or Jogada Gundi.
Option A is wrong because Punjab is a flat alluvial plain with no waterfall of this kind. Options C and D are wrong as Jammu and Kashmir and Ladakh lie in the Himalayan north, far from the Sharavathi; India's highest waterfall, Kunchikal, is also in Karnataka.
Exam tip: Jog on the Sharavathi and Kunchikal on the Varahi are both in Karnataka; Dudhsagar is in Goa.
In which part of India does the hot wind 'Loo' blow?
- A.West and Southwestern
- B.North and Northwestern
- C.East and Northeastern
- D.South and Southwestern
Show answer
Correct answer: B. North and Northwestern
Explanation
The correct answer is B, North and Northwestern. The Loo is the hot, dry wind of the northern and north-western plains of India.
The Loo blows from the west and north-west during the day in May and June, when the land heats up and a low pressure trough forms over north-west India. Rajasthan, Punjab, Haryana, Delhi, Uttar Pradesh and Bihar feel it most, and it often pushes the afternoon temperature past 45°C and causes heat stroke. It dies down at night and disappears once the monsoon arrives.
A is wrong: the west and south-west coast is cooled by sea breezes and the pre-monsoon Mango showers. C is wrong: the east and north-east get Kaal Baisakhi thunderstorms and Bardoli Chheerha instead. D is wrong: the south and south-west are peninsular and coastal, where the sea keeps temperatures even.
Exam tip: Loo - hot summer wind of north India; Kaal Baisakhi - Bengal; Mango showers - Kerala and Karnataka.
Which of the following crops is described as - 'It is a crop which is used both as food and fodder. It is a Kharif crop that requires temperature between 21°C to 27°C and grows well in old alluvial soil'?
- A.Sesamum
- B.Maize
- C.Bajra
- D.Ragi
Show answer
Correct answer: B. Maize
Explanation
The correct answer is B, Maize. Maize is the crop grown both as food and as fodder, needing 21°C to 27°C and old alluvial soil.
Maize is a kharif crop sown with the onset of the monsoon, though in Bihar and a few other states it is also raised in the rabi season. Its output rose with high-yielding seeds, fertilisers and irrigation under the Green Revolution. Karnataka, Madhya Pradesh, Bihar, Tamil Nadu, Telangana and Maharashtra are among the leading producers, and the grain also feeds the poultry and starch industries.
A is wrong: sesamum, or til, is an oilseed, a kharif crop in the north and a rabi crop in the south. C is wrong: bajra grows on sandy soils and shallow black soil in dry areas. D is wrong: ragi is a hardy millet of dry regions, grown on red, black, sandy and shallow soils.
Exam tip: Maize - kharif, 21°C to 27°C, old alluvial soil, food and fodder both.
Read the following statements carefully and choose the correct option: Assertion (A): Iron and steel is considered a heavy industry. Reason (R): It requires lightweight raw materials like cotton and rubber.
- A.Both A and R are true, and R is the correct explanation of A
- B.Both A and R are true, but R is not the correct explanation of A
- C.A is true, but R is false
- D.A is false, but R is true
Show answer
Correct answer: C. A is true, but R is false
Explanation
The correct answer is C, A is true, but R is false. Iron and steel is indeed a heavy industry, but not because of light raw materials.
Industries are classified by the weight of the material they handle. A heavy industry uses bulky, heavy raw materials and turns out bulky products, so iron and steel, which consumes iron ore, coking coal, limestone, dolomite and manganese by the tonne, is the classic example. A light industry uses light raw materials and gives light finished goods, and it is here that cotton, rubber, silk and electronics belong. That is why the reason given is false: cotton and rubber are never the inputs of an iron and steel plant.
A is wrong as a choice because the reason is false. B is wrong for the same reason. D is wrong because the assertion about iron and steel being a heavy industry is perfectly true.
Exam tip: Heavy industry - iron and steel, cement, shipbuilding; light industry - cotton textiles, electronics, rubber goods.
Which of the following is a tributary of the river Brahmaputra that flows through Bhutan?
- A.Ayeyarwady River
- B.Sittaung River
- C.Chindwin River
- D.Wang Chhu River
Show answer
Correct answer: D. Wang Chhu River
Explanation
The correct answer is D, Wang Chhu River. The Wang Chhu flows through western Bhutan and joins the Brahmaputra system in India.
The Wang Chhu rises in the Himalayas of Tibet, passes Thimphu and Paro in Bhutan, and enters West Bengal, where it is known as the Raidak. It then flows through Assam and meets the Brahmaputra. Several other Brahmaputra tributaries also come down from Bhutan, among them the Manas, the Sankosh and the Torsa, while the Subansiri, Dibang and Lohit join it in Arunachal Pradesh and Assam.
A is wrong: the Ayeyarwady, or Irrawaddy, is the main river of Myanmar and drains into the Andaman Sea. B is wrong: the Sittaung is also a river of Myanmar. C is wrong: the Chindwin is the largest tributary of the Ayeyarwady in Myanmar.
Exam tip: Brahmaputra tributaries from Bhutan - Wang Chhu (Raidak), Manas, Sankosh, Torsa; the Ayeyarwady, Sittaung and Chindwin belong to Myanmar.
