• Question 1 of 5 1. Question Consider the following statements about the Major Atmospheric Cherenkov Experiment (MACE) Observatory: The MACE Observatory is located in the Himalayas, making it the highest imaging Cherenkov telescope in the world. The primary objective of the MACE project is to study cosmic rays using radio waves. The observatory was developed indigenously by Bhabha Atomic Research Centre (BARC) with support from Indian institutions. How many of the above statements is/are incorrect? (a) Only one (b) Only two c) All three d) None Correct Solution: a) Only statement 2 is incorrect. The Major Atmospheric Cherenkov Experiment (MACE) Observatory is a landmark scientific installation located in Hanle, Ladakh, at an altitude of 4,300 meters, making it the highest imaging Cherenkov telescope in the world. This location provides ideal atmospheric conditions with minimal light pollution and dry air, crucial for observing high-energy cosmic phenomena. The main goal of MACE is not to study cosmic rays using radio waves but to detect very high-energy gamma rays from astrophysical sources like supernova remnants, pulsars, and active galactic nuclei using Cherenkov imaging technique. This technology captures the faint light produced when gamma rays interact with Earth’s atmosphere, generating particle showers. Importantly, MACE is an example of indigenous scientific capability; it was developed by the Bhabha Atomic Research Centre (BARC) in collaboration with other Indian organizations such as the Electronics Corporation of India Limited (ECIL).

• Question 4 of 5 4. Question Why are Pluto and Charon often referred to as a “double dwarf planet system”? a) Due to their similar compositions of methane and nitrogen. b) Due to the close size and mass ratio between Pluto and Charon. c) Because both are located in the asteroid belt. d) Because Charon is more massive than Pluto. Correct solution: b) Pluto and Charon are referred to as a “double dwarf planet system” primarily due to their unusual size and mass ratio. Unlike most planetary systems where the moon orbits close to the planet’s center, Charon is about 50% the diameter of Pluto and has more than 12% of Pluto’s mass, making it one of the largest moon-to-planet ratios in the solar system. This significant mass results in the barycenter, or the center of mass around which both bodies orbit, lying outside Pluto’s surface—a rare trait among planet-moon systems. This configuration leads scientists to view Pluto and Charon more as a binary or “double dwarf planet” system rather than the traditional primary-satellite relationship. Their orbital dynamic is a striking example of gravitational balance in the outer solar system, especially within the Kuiper Belt.

• Question 5 of 5 5. Question Consider the following statements about the ecological role of the Indian Wild Ass: The Indian Wild Ass plays a role in seed dispersal, contributing to vegetation growth. It primarily inhabits forested areas where it clears dense undergrowth through grazing. The grazing activity of wild asses helps in creating pathways, thereby influencing habitat creation. How many of the above statements is/are correct? (a) Only one (b) Only two c) All three d) None Correct Solution: b) The Indian Wild Ass (Equus hemionus khur), found primarily in the Little Rann of Kutch in Gujarat, plays a vital ecological role in arid and semi-arid landscapes. Statement 1 is correct: as a grazer and browser, it aids in seed dispersal, which contributes to vegetation regeneration and ecological balance in these dry ecosystems. Seeds consumed during grazing are excreted at different locations, facilitating plant growth across a wider area. Statement 2 is incorrect: the Indian Wild Ass does not inhabit forested regions. Instead, it thrives in open, saline desert plains, grasslands, and scrublands, where it is adapted to harsh conditions. Forests are not part of its natural habitat. Statement 3 is correct: their grazing and movement patterns help form natural trails and open up dense patches, enabling smaller species to access new areas, thus promoting microhabitat creation and increasing biodiversity.
