Which river is associated with Jamshedpur's location and gives the town of Jugsalai its identity?
Correct Answer: B. Kharkai (and Subarnarekha confluence near Jamshedpur)
Jamshedpur is located at the confluence of the Subarnarekha and Kharkai rivers. The Kharkai River joins the Subarnarekha near Jamshedpur, and the city was established at this confluence point because of the abundant water supply for the steel plant. The rivers provide essential cooling and process water for Tata Steel's operations.
Coal India Limited (CIL), whose subsidiaries operate in Jharkhand, is the world's largest what?
Correct Answer: B. Coal mining company by production volume
Coal India Limited (CIL) is the world's largest coal mining company by production volume, producing over 700 million tonnes annually. Its subsidiaries BCCL and CCL in Jharkhand mine coking and non-coking coal respectively. CIL is a Maharatna central public sector enterprise and one of India's most profitable state-owned companies.
Jharkhand has the largest reserves of which coking coal type used in the steel industry?
Correct Answer: B. Prime coking coal (best quality for steel making)
Jharkhand (specifically the Jharia coalfield) has India's largest and best quality reserves of prime coking coal used in integrated steel plants. Prime coking coal is also called metallurgical coal and has strict specifications for coke strength, coking properties, and low sulfur content. Jharia prime coking coal reduces India's dependence on imported coking coal for steel production.
The Jharkhand government has proposed a Steel Hub policy. What is the vision?
Correct Answer: B. Develop Jharkhand as a major global steel hub by attracting new steel investments alongside Tata Steel and SAIL
The Jharkhand government has promoted a vision to develop the state as a major steel hub by leveraging its coal, iron ore, and water resources to attract new steel plant investments alongside existing giants Tata Steel and SAIL. The government offers incentives for new steel and metal industries to set up in Jharkhand. This policy aims to add value to Jharkhand's raw materials domestically rather than exporting them.
The Maoist (Naxalite) insurgency in Jharkhand is closely linked to which issue?
Correct Answer: B. Land acquisition, displacement, and tribal rights disputes related to mining
The Maoist insurgency in Jharkhand's 'Red Corridor' districts is closely linked to displacement of tribal communities from their land for mining projects, inadequate rehabilitation, and perceived exploitation of Adivasi communities by mining companies and the state. Districts like Latehar, Giridih, Chatra, and Palamu are affected by Naxalite violence. Addressing tribal land rights and mining governance is seen as key to reducing Naxalite influence.
What is the approximate area of the Jharia coalfield (one of the world's largest coal seams)?
Correct Answer: B. 453 sq km
The Jharia coalfield covers approximately 453 square kilometres in Dhanbad district of Jharkhand. This makes it one of the most concentrated coal deposits in the world. The coalfield contains billions of tonnes of coking coal reserves, though extensive mining and underground fires have affected accessibility of remaining reserves.
The Steel Authority of India Limited (SAIL) was established in which year?
Correct Answer: B. 1973
SAIL (Steel Authority of India Limited) was established in January 1973 to manage the major steel plants including Bokaro in Jharkhand. Prior to SAIL, steel plants were managed by Hindustan Steel Limited. SAIL is now one of India's largest companies by revenue and production capacity.
Which gas-based power project is located in the Jharkhand-West Bengal border area using pipeline gas?
Correct Answer: C. R-LNG based power plants in the Bokaro-Dhanbad area
The Bokaro-Dhanbad industrial area of Jharkhand has gas-based power generation facilities using regasified LNG (R-LNG) supplied through pipelines from LNG terminals. Industrial consumers in Jharkhand are increasingly using natural gas as a cleaner fuel alternative to coal. The HBJ (Hazira-Bijaipur-Jagdishpur) gas pipeline provides natural gas to industries in eastern India including Jharkhand.
Jharkhand's rich mineral resources attracted what during British colonial era?
Correct Answer: B. British establishment of coal mining companies and railways for mineral extraction
Jharkhand's mineral wealth, particularly coal, attracted British investment in the late 19th and early 20th centuries. The British established coal mining companies, railways to transport minerals, and industrial infrastructure in the region. This colonial extraction-based economy set the pattern for Jharkhand's industrial development but also led to the exploitation of tribal land and labour.
East Singhbhum district of Jharkhand is significant for which combination of minerals?
Correct Answer: B. Iron ore, copper, and uranium
East Singhbhum district (Dhalbhum) is one of Jharkhand's most mineral-rich districts, containing significant deposits of iron ore, copper (Mosaboni, Surda mines), and uranium (Jaduguda). The district is also the location of Jamshedpur (Tata Steel) and the Ghatsila copper complex. This concentration of multiple minerals in one district makes East Singhbhum uniquely important in Jharkhand's mining landscape.
