Which of the statements given above is/are correct? a) 1 and 2 only b) 2 and 3 only d) 1 only d) 1, 2, and 3 Correct Solution: a) Statement 1 is correct as UDAN 5.0 introduces a new focus category for aircraft with more than 80 seats. Statement 2 is correct because, under UDAN 5.0, there is no restriction on the distance between the origin and destination of the flights. Statement 3 is incorrect because the viability gap funding cap under UDAN 5.0 differs for priority areas (60%) and non-priority areas (20%). Incorrect Solution: a) Statement 1 is correct as UDAN 5.0 introduces a new focus category for aircraft with more than 80 seats.

• Question 2 of 10 2. Question 1 points What does Nitrogen-use efficiency (NUE) refer to in the context of rice cultivation? a) The amount of nitrogen absorbed by the soil relative to the amount applied. b) The percentage of nitrogen lost to the environment during rice cultivation. c) The crop yield relative to the amount of nitrogen (both natural and artificial) available to it. d) The cost-effectiveness of nitrogen fertilizers used in rice farming. Correct Solution: c) A study has identified significant variations in nitrogen-use efficiency(NUE) among popular Indian rice varieties. This finding could lead to the development of new rice varieties that require less nitrogen while maintaining high yields,potentially reducing costs associated with imported fertilizers and decreasing nitrogen-related pollution. Nitrogen-use efficiency refers to the crop yield relative to the amount of nitrogen (both natural and artificial) available to it. The study found that some rice varieties are five times more efficient in nitrogenuse than others, although higher NUE doesn’t always correlate with the highest yields, which farmers typically prefer. The researchers emphasize the need to shift focus from merely increasing crop yields, as done during the Green Revolution, to improving NUE to reduce fertilizer waste and environmental pollution.

• Question 3 of 10 3. Question 1 points Consider the following statements about antimatter: Antimatter is composed of antiparticles, which have the same mass as ordinary matter particles but possess opposite electric charges. The antimatter counterpart of an electron is the positron, which has a positive charge. When matter and antimatter come into contact, they annihilate each other, releasing energy. Which of the statements given above is/are correct? a) 1 and 2 only b) 2 and 3 only c) 1 and 3 only d) 1, 2, and 3 Correct Solution: d) Scientists discovered the heaviest antimatter particle, named antihyperhydrogen-4, at the Relativistic Heavy Ion Collider in New York. What is Antimatter? Antimatter is a type of matter composed of antiparticles, which have the same mass as ordinary matter particles but possess opposite electric charges. For example, the antimatter counterpart of an electron (which has a negative charge) is the positron, which has the same mass as an electron but a positive charge. Similarly, the antiproton is the antimatter equivalent of a proton, having the same mass but an opposite, negative charge. Example: Matter: A hydrogen atom is made of one proton (positively charged) and one electron (negatively charged). Antimatter: The antimatter version, antihydrogen, consists of one antiproton (negatively charged) and one positron (positively charged). Difference from Matter: The key difference between matter and antimatter lies in the charges of their particles. When matter and antimatter come into contact, they annihilate each other, releasing energy in the process. This process is governed by the same fundamental forces, but the charge reversal leads to the annihilation phenomenon. Despite equal amounts of matter and antimatter being produced at the universe’s birth, matter dominates today. Scientists are still exploring why this imbalance occurred.
