Ballast water is used in ship for its stability. However it poses big environmental risk that sometimes it carries invasive species and discharge in some other location. Under the Convention by IMO, all ships in international traffic are required to manage their ballast water and sediments to a certain standard, according to a ship-specific ballast water management plan.

Statement 1 is incorrect. The Agni missile is a family of medium to intercontinental range ballistic missiles developed by India. Prithvi is a tactical surface-to-surface short-range ballistic missile (SRBM) developed by DRDO of India under the Integrated Guided Missile Development Program (IGMDP). It is deployed by India’s Strategic Forces Command.

Statement 2 is correct. The Astra is an active radar homing beyond-visual-range air-to-air missile (BVRAAM)developed by the Defence Research and Development Organisation  (DRDO), India. The Akash is a medium-range mobile surface-to-air missile defense system developed by the Defence Research and Development Organisation (DRDO).

Statement 2 is incorrect. Large Hadron Collider (LHC), was built by the European Organization for Nuclear Research (CERN).

Statement 1 is correct. The Large Hadron Collider (LHC) is the world’s largest and most powerful particle accelerator. The LHC consists of a 27-kilometre ring of superconducting magnets with a number of accelerating structures to boost the energy of the particles along the way.

Statement 3 is correct. It is located beneath the franco-swiss border in Europe. At CERN, the European Organization for Nuclear Research, physicists and engineers are probing the fundamental structure of the universe.

Statement 1 is incorrect. Maglev is a transport method that uses magnetic levitation to move vehicles without making contact with the ground. This technology mainly used in train transportation.  The first maglev patent awarded to a German inventor Alfred Zehden.

Statement 2 is correct. Maglev is a system of train transportation that uses two sets of magnets, one set to repel and push the train up off the track as in levitation, then another set to move the ‘floating train’ ahead at great speed taking advantage of almost no friction.

Statement 3 is correct.The great speed by using this technology taking advantage of almost no friction.

All the above statements are correct. Coal Bed Methane (CBM) is natural gas found in coal seams. It mainly consists of Methane (CH4) with minor amounts of nitrogen, carbon dioxide and heavier hydrocarbons like ethane. Methane has been labeled as a Green House Gas (GHG) by United Nations Framework Convention on Climate Change (UNFCCC). Its global warming potential is 21 times more than that of the Carbon Dioxide. But CBM is considered as a clean fuel which on combustion emits only carbon dioxide and water.

All the above statements are correct.

LIDAR stands for Light Detection and Ranging. It is a remote sensing method that uses light in the form of a pulsed laser to measure ranges to the Earth. It helps to examine both natural and manmade environments with accuracy and flexibility. The technology is used to map the land and is used to measure seafloor and riverbed elevations.

Statement 1 is incorrect. DNA fingerprinting is a method used to identify an individual from a sample of DNA by looking at unique patterns in their DNA. The DNA Fingerprint pattern of a child is 50% bands similar to father and rest similar to mother.

Statement 2 is correct DNA Fingerprinting relies on difference in junk DNA patterns between individuals.
