Question 1 of 5
1. Question
Consider the following statements with respect to ‘Petroleum Coke (Pet Coke)’
- It is a final carbon-rich solid material and residual waste material extracted from oil refining
- It emits toxic gases like carbon dioxide, nitrous oxide, mercury, arsenic and chromium on burning
- It is low in calorific value and easy to transport and store
How many of the statement(s) given above are correct
Correct
Solution (b)
Statement Analysis:
Statement 1 Statement 2 Statement 3 Correct Correct Incorrect It is a final carbon-rich solid material and residual waste material extracted from oil refining. It is a spongy, solid residue from oil distillation that can be burned for fuel similar to coal. It releases toxic gases like carbon dioxide, nitrous oxide, mercury, arsenic, chromium, nickel, and hydrogen chloride after burning. It is high in calorific value and easy to transport and store. Context – The Union government of India permitted the import of pet coke for making graphite anode material for lithium-ion batteries.

Question 2 of 5
2. Question
Consider the following statements with respect to ‘Kavach System’
- It is an indigenously developed Automatic Train Protection (ATP) system developed by the Research Design and Standards Organisation
- It is a set of electronic devices and Radio Frequency Identification devices installed in locomotives as well the tracks which communicate through ultra-high radio frequencies
- The system can alert the loco pilot, take control of the brakes and bring the train to a halt automatically when it notices another train on the same line
How many of the statement(s) given above are correct
Correct
Solution (c)
Statement Analysis:
Statement 1 Statement 2 Statement 3 Correct Correct Correct Kavach System is an indigenously developed Automatic Train Protection (ATP) system. Kavach was developed by the Research Design and Standards Organisation (RDSO) under Indian Railway (IR) in collaboration with Medha Servo Drives Pvt Ltd, HBL Power Systems Ltd and Kernex Microsystems. It is a set of electronic devices and Radio Frequency Identification devices installed in locomotives, in the signalling system as well the tracks, that talk to each other using ultra-high radio frequencies to control the brakes of trains and also alert drivers, all based on the logic programmed into them. The system can alert the loco pilot, take control of the brakes and bring the train to a halt automatically when it notices another train on the same line within a prescribed distance. The device also continuously relays the signals ahead to the locomotive, making it useful for loco pilots in low visibility. Context – It was in news due to the recent train accident in Odisha

Question 3 of 5
3. Question
With reference to ‘Seaweeds’, consider the following statements
Statement 1 – Seaweeds are generally anchored to the sea bottom or other solid structures by rootlike “holdfasts”
Statement 2 – Substances found in seaweed help increase the production of a protein that metabolises fat effectively
Which one of the following is correct in respect of the above statements?
Correct
Solution (b)
Statement Analysis:
Statement 1 Statement 2 Correct Correct Seaweeds are generally anchored to the sea bottom or other solid structures by rootlike “holdfasts,” which perform the sole function of attachment and do not extract nutrients as do the roots of higher plants. Animal studies have found that substances found in seaweed help increase the production of a protein that metabolises fat effectively. Both the statements are independent of each other. Hence, statement 2 is not the correct explanation of statement 1 Context – Clusters of brown Sargassum seaweed reported to be infested by flesh-eating bacteria were recently found awash in Florida.
