Question 1 of 5
1. Question
1 pointsWhat is TROPEX, recently seen in the news?
Correct
Answer: B
Explanation:
• Option B is correct: The 2025 edition of Indian Navy’s capstone Theatre Level Operational Exercise (TROPEX), is currently underway in the Indian Ocean Region.

Question 2 of 5
2. Question
1 pointsConsider the following statements:
- All eggs and all sperm contain an X chromosome.
- Individuals with an XX chromosome configuration can never develop male characteristics.
Which of the statements given above is/are correct?
Correct
Answer: D
Explanation:
- Statement 1 is not correct: All eggs contain an X chromosome, but sperm can carry either an X or a Y chromosome. Since not all sperm contain an X chromosome, this statement is incorrect.
Statement 2 is not correct: While XX individuals usually develop as females, rare cases exist where an XX individual with an SRY gene translocation can develop male characteristics, such as testes. Therefore, this statement is also incorrect.
Incorrect
Answer: D
Explanation:
- Statement 1 is not correct: All eggs contain an X chromosome, but sperm can carry either an X or a Y chromosome. Since not all sperm contain an X chromosome, this statement is incorrect.
Statement 2 is not correct: While XX individuals usually develop as females, rare cases exist where an XX individual with an SRY gene translocation can develop male characteristics, such as testes. Therefore, this statement is also incorrect.

Question 3 of 5
3. Question
1 pointsConsider the following statements with reference to quasars:
- They are distant galaxies whose bright cores are powered by supermassive black holes.
- Quasars occur when immense amounts of matter fall into a supermassive black hole, spiraling around it in the form of a disk before entering.
Which of the statements given above is/are correct?
Correct
Answer: C
Explanation:
- Statement 1 is correct: Quasars are distant galaxies whose incredibly bright cores are powered by supermassive black holes. Quasars have been found with luminosities between 10 to 100,000 times that of our Milky Way galaxy, generated from an area just a few light-days to a few light-years across.
Statement 2 is correct: Quasars occur when immense amounts of matter fall into a supermassive black hole, spiraling around it in the form of a disk before entering. This “accretion disk” is subjected to extreme gravitational and frictional forces, causing the gas and dust to heat up to millions of degrees and become luminous, blasting out dazzling jets of material into the universe. Together, the jets and glowing disk outshine their host galaxies.

Question 4 of 5
4. Question
1 pointsConsider the following statements with reference to Monarch Butterfly:
- It is native to the Asian continent.
- Males possess distinguishing black dots along the veins of their wings and are slightly bigger than females.
- They lay their eggs in a wide selection of habitats.
How many of the above statements are correct?
Correct
Answer: A
Explanation:
- Statement 1 is not correct: Monarch butterflies embark on a marvelous migratory phenomenon. They travel between 1,200 and 2,800 miles or more from the northeast United States, and southeast Canada to the mountain forests in central Mexico, where they find the right climate conditions to hibernate from the beginning of November to mid-March.
- Statement 2 is correct: The monarch butterfly is known by scientists as Danaus plexippus, which in Greek literally means “sleepy transformation.” The name evokes the species’ ability to hibernate and metamorphize. Adult monarch butterflies possess two pairs of brilliant orange-red wings, featuring black veins and white spots along the edges. Males, who possess distinguishing black dots along the veins of their wings, are slightly bigger than females. Each adult butterfly lives only about four to five weeks.
Statement 3 is not correct: Milkweed is the only plant on which monarchs will lay their eggs and the only source of food for baby caterpillars. But urban planning and agricultural expansion have paved and plowed over millions of acres of milkweed. Planting the right species of milkweed in a given area can help these amazing butterflies and other pollinators thrive.

Question 5 of 5
5. Question
1 pointsConsider the following statements with GreenVoyage2050 initiative:
- It is a global programme supporting developing countries to reduce emissions from ships.
- It has been initiated by the United Nations Environment Programme.
Which of the statements given above is/are correct?
Correct
Answer: A
Explanation:
- Statement 1 is correct and 2 is not correct: GreenVoyage2050 is a global programme supporting developing countries to reduce emissions from ships, in line with the 2023 International Maritime Organisation GHG Strategy.
- Phase 1 was launched in May 2019 and ran until December 2023, delivering activities to support the development of legal and policy frameworks for reducing emissions from ships in various partnering countries, and scoping out potential pilot projects, through the GreenVoyage2050 Accelerator, to demonstrate energy efficiency technologies and undertaking feasibility studies for their implementation.
Phase 2 began in January 2024, running until December 2030, building upon the foundation laid by Phase 1, and plans to scale up implementation of activities, with a focus on delivering pilot projects and technology demonstrations, and the establishment of a financial mechanism to support developing countries to access financing for technology uptake.
