• Question 4 of 5 4. Question Consider the following statements regarding the criteria for appointment of the Chief Justice of India (CJI): The CJI can be appointed based on a rotation policy from different regional Supreme Court benches. Merit and integrity are considered alongside seniority in CJI appointments. The CJI is selected by a committee of sitting Supreme Court judges and then recommended to the President. How many of the above statements is/are correct? a) Only one b) Only two c) All three d) None Correct Solution: A Statement 1 is incorrect because there is no rotation policy for appointing the CJI based on regional Supreme Court benches. The appointment is based primarily on seniority and the outgoing CJI’s recommendation. Statement 2 is correct, as factors like merit and integrity, along with seniority, are considered when making the recommendation. This was evident in past appointments where the consideration of these factors led to certain judges being recommended or passed over. Statement 3 is incorrect because the selection of the CJI is not made by a committee of Supreme Court judges. Instead, the outgoing CJI recommends the senior-most judge to the President, following established conventions. Incorrect Solution: A Statement 1 is incorrect because there is no rotation policy for appointing the CJI based on regional Supreme Court benches. The appointment is based primarily on seniority and the outgoing CJI’s recommendation. Statement 2 is correct, as factors like merit and integrity, along with seniority, are considered when making the recommendation. This was evident in past appointments where the consideration of these factors led to certain judges being recommended or passed over.

• Question 5 of 5 5. Question Consider the following statements about the functioning of atomic clocks: Quartz crystal oscillators are essential components of atomic clocks. Atomic clocks primarily depend on the vibration of caesium atoms for timekeeping. Atomic clocks compare the vibrations of atoms with that of quartz oscillators to maintain precision. Atomic clocks are less accurate than GPS satellites in time measurement. Which of the above statements are correct? (a) 1 and 2 only (b) 1, 3, and 4 only (c) 1, 2 and 3 only (d) 1, 2, 3 and 4 Correct Solution: C Quartz crystal oscillators are also essential components of atomic clocks, providing a base frequency that is later compared to the atomic transitions, so statement 1 is correct. Atomic clocks rely on the vibration of caesium atoms (or other atoms like hydrogen or rubidium) for their precise timekeeping, making statement 2 correct. Statement 3 is also correct, as atomic clocks compare the consistent frequency of atom vibrations with quartz oscillators to ensure precision in time measurement. Statement 4 is incorrect because atomic clocks are more accurate than the clocks in GPS satellites. In fact, GPS satellites use atomic clocks to maintain the precision required for navigation. Topic Information Atomic Clock An atomic clock is a highly accurate timekeeping device that combines a quartz crystal oscillator with an atom, typically caesium or hydrogen, to measure time precisely. It uses the consistent frequency of atoms to maintain accurate time, making it more stable than conventional quartz clocks. It was Invented in 1955 by Louise Essen. It combines a quartz crystal oscillator with an atom for precise timekeeping. Types of Atomic Clocks Caesium and hydrogen maser atomic clocks Hydrogen maser clocks are more accurate and used in scientific research. Working Quartz crystal oscillators are commonly used in modern clocks, vibrating at a precise frequency when voltage is applied. However, they become slightly slow every hour and require frequent adjustments. Atomic clocks are like super accurate timekeepers. They use special atoms, usually caesium atoms, which vibrate at a very steady rate. By sending microwaves to these atoms, we can make them vibrate even more regularly. Then, we compare these vibrations with the vibrations of a quartz crystal in a regular clock. The most advanced atomic clocks lose just one second every 300 billion years. Incorrect Solution: C Statement 1 is correct; Great Nicobar is the southernmost tip of India (containing Indira Point) and features Galathea Bay, a critical nesting site for leatherback turtles. Statement 2 is correct; the island sits adjacent to the Six Degree Channel and the Malacca Strait, giving it immense strategic leverage over global maritime trade.
