• Question 1 of 5 1. Question Consider the following statements about iron ore extraction in India: Bailadila mines in Chhattisgarh are known for high-grade iron ore. The majority of India’s iron ore reserves are hematite, while magnetite reserves are comparatively lower. India’s iron ore mines are located primarily in coastal areas for easy export. How many of the above statements is/are incorrect? a) Only one b) Only two c) All three d) None Correct Solution: A Statement 1 is correct. The Bailadila range in southern Chhattisgarh is internationally known for its very high-grade hematite iron ore, often exceeding 65% iron content, and has long been a major source for both domestic steel plants and exports. Statement 2 is also correct. India’s iron ore resource base is dominated by hematite, which is more readily usable in steelmaking, while magnetite reserves exist in smaller proportions and are largely concentrated in parts of Karnataka, Andhra Pradesh, and Tamil Nadu. Statement 3 is incorrect. Iron ore mining in India is primarily concentrated in the Peninsular Plateau region—such as Odisha, Jharkhand, Chhattisgarh, Karnataka, and parts of Maharashtra—not mainly in coastal areas. Although proximity to ports helps exports, geological distribution, not coastal location, determines the location of iron ore mines. Incorrect Solution: A Statement 1 is correct.

• Question 3 of 5 3. Question Consider the following statements regarding lab-grown diamonds (LGDs): LGDs are created in laboratories using different processes than those involved in the formation of natural diamonds. The Chemical Vapor Deposition (CVD) method is used to grow LGDs at temperatures around 800°C. LGDs are chemically different from natural diamonds due to their artificial creation. How many of the above statements is/are correct? a) Only one b) Only two c) All three d) None Correct Solution: b) Statement 1 is correct because lab-grown diamonds are produced through controlled technological processes such as High Pressure High Temperature (HPHT) or Chemical Vapor Deposition (CVD), whereas natural diamonds form over billions of years deep inside the Earth’s mantle under extreme pressure and temperature conditions. Statement 2 is also correct. In the CVD process, a carbon-rich gas mixture is activated at relatively moderate temperatures, typically in the range of about 700–900°C, allowing carbon atoms to deposit layer by layer on a diamond seed crystal. Statement 3 is incorrect. Chemically, both lab-grown and natural diamonds are composed of pure crystalline carbon arranged in the same cubic lattice structure. Their physical and chemical properties are essentially identical, which is why advanced instruments are required to distinguish between them. Differences, if any, relate to growth patterns or trace impurities, not to fundamental chemistry.

• Question 5 of 5 5. Question Which of the following is a key objective of the Square Kilometre Array Observatory? a) Search for new energy sources b) Build communication satellites for global internet c) Launch space probes for Mars exploration d) Detect and study gravitational waves Correct Solution: D The Square Kilometre Array Observatory is one of the world’s most ambitious scientific projects in the field of radio astronomy, designed to deepen our understanding of the universe through ultra-sensitive radio observations. A key scientific objective of the SKA is the detection and study of gravitational waves, particularly low-frequency gravitational waves that cannot be observed by ground-based laser interferometers like LIGO. The SKA aims to achieve this through a technique known as pulsar timing arrays, where extremely regular radio signals from millisecond pulsars are monitored for tiny distortions caused by passing gravitational waves. This will allow scientists to study cosmic events such as mergers of supermassive black holes and the structure of spacetime itself.
