Question 1 of 5 NDA MCQ

Which one among the following states is the leading producer of Manganese in India ?

Detailed Explanation

Correct Answer

✓ Option A is correct. Madhya Pradesh leads in manganese production in India.

📖 Core Anchor Concept

The question pertains to the production of manganese ore in India. Manganese is a vital mineral for steel production and various industrial applications.

📜 Detailed Breakdown & Chronology

Madhya Pradesh emerged as the leading producer of manganese ore in India, contributing approximately 33% of the total production in 2019-20. This is a significant share, as other major contributors include Maharashtra (25%) and Odisha (19%). The mineral is crucial for various industries, making its production a key economic factor.

Geologically, manganese deposits in Madhya Pradesh are primarily found in the form of deposits in the Bastar plateau region, characterized by its rich mineral base.

Question 3 of 5 NDA MCQ

Consider the following statements with regardto a steel plant:

1. It was set up in 1964 with Russian collaboration.

2. It receives iron ore from the Rourkela region.

3. Water and hydel power is supplied by the Damodar Valley Corporation.

Identify the steel plant on the basis of the abovefacts:

Detailed Explanation
✓

1. Correct Answer

Option B is correct.

📖 Short Explanation

The question involves identifying the steel plant set up with Russian collaboration, receives iron ore from the Rourkela region, and uses resources from the Damodar Valley Corporation, which are characteristic of the Bokaro Steel Plant.

💡 3. Why Correct Answer is Correct

The Bokaro Steel Plant fulfills all the given conditions:

  • - It was established in 1964 with assistance from the USSR, marking it as a collaboration with Russian entities.
  • - It receives iron ore from Rourkela, which is well-known for its rich mines in the state of Odisha.
  • - Since the plant is located in Jharkhand, integrated resource management with the Damodar Valley Corporation ensures regular water and power supply, critical for steel production.

❌ 4. Why Other Options are Wrong

  • •Option A (Bhilai Steel Plant): It was established with Soviet aid but receives its iron ore from Dalli-Rajhara, not Rourkela.
  • •Option C (Rourkela Steel Plant): Although it receives iron ore from nearby regions, this plant was established with German aid, not Russian.
  • •Option D (Durgapur Steel Plant): Built with British collaboration, it does not match the Russian collaboration criterion, nor does it solely rely on Rourkela for iron ore.

NDA Speed-Run / Mnemonic Shortcut

Remember, Bokaro is associated with Russia and DVC, while Bhilai and Durgapur are linked with USSR and UK, respectively. This helps in quick identification on the exam day.

🎯

5. Key Learning Point

Understand the pivotal features and foreign collaborations of Indian steel plants like Bokaro, which symbolize post-independence industrial alliances.

A detailed map showcasing locations of major steel plants in India, color-coded by country of collaboration, would simplify identifying Bokaro's association with Russia and its logistics.

Question 4 of 5 NDA MCQ

Which one among the following is NOT a major oil field located in Gujarat?

Detailed Explanation
✓

1. Correct Answer

Option D is correct. Moran is not a major oil field located in Gujarat.

📖 Short Explanation

Gujarat is home to several significant oil fields that contribute to India's onshore oil production. However, Moran is an oil field located in Assam, not Gujarat.

💡 3. Why Correct Answer is Correct

The question asks us to identify the oil field that is not located in Gujarat. Gujarat's key oil fields include Ankleshwar, Kosamba, and Mehsana, all known for their contribution to oil production in the state. On the other hand, the Moran oil field is located in the Dibrugarh district of Assam, making it geographically disconnected from the other options. Thus, Moran being in Assam and not in Gujarat, fulfills the condition of being the correct option.

❌ 4. Why Other Options are Wrong

  • •Option A: Ankleshwar is a well-known oil field in Gujarat, actively involved in oil production.
  • •Option B: Kosamba is located in Gujarat, contributing to the state's oil output
  • •Option C: Mehsana is another significant oil field in Gujarat, known for its production activities.

Remember key oil fields in Gujarat with the acronym "AKM" — Ankleshwar, Kosamba, Mehsana. Any option not fitting "AKM" is the outlier.

🎯

5. Key Learning Point

Familiarity with major geographical locations of natural resources is crucial in exams like NDA.

6. Visual Suggestion

A detailed map of India marking key oil fields in Gujarat such as Ankleshwar, Kosamba, and Mehsana alongside Moran in Assam would clearly illustrate their geographical distribution.
