• Question 1 of 10 1. Question 1 points Consider the following statements regarding the Pradhan Mantri Matsya Sampada Yojana (PMMSY): It is a Central Sector Scheme designed to replace all existing state-level fisheries welfare programs. The scheme incorporates the promotion of seaweed cultivation and ornamental fisheries to diversify livelihoods. It aims to modernize the fisheries value chain specifically through the development of fishing harbours and cold chain facilities. Which of the above statements are correct? (a) 1 and 2 only (b) 1 and 3 only (c) 2 and 3 only (d) 1, 2 and 3 Correct Solution: C Statement 1 is incorrect because PMMSY is an umbrella scheme that operates through two components: Central Sector (CS) and Centrally Sponsored Scheme (CSS). It does not “replace” all state programs but provides a comprehensive framework for holistic development across the country. Statement 2 is correct as the scheme explicitly supports non-traditional activities like biofloc farming, seaweed cultivation, and ornamental fisheries to increase income and provide climate-resilient livelihoods. Statement 3 is correct because a core pillar of the scheme is infrastructure development, which includes the modernization of fishing harbours, fish landing centers, and the establishment of robust post-harvest management systems like cold chains. The scheme represents a shift from traditional fishing to a more technology-driven and value-added approach, aiming to reduce post-harvest losses, which are currently high in the Indian fisheries sector. This holistic focus ensures both economic growth for fishers and the sustainable management of marine and inland aquatic resources.

• Question 3 of 10 3. Question 1 points Consider the following statements regarding “Jhumka” jewellery and its heritage: It is a three-dimensional, bell-shaped earring that originated during the Mughal era in Northern India. These designs are ineligible for patent protection under current Intellectual Property regimes because they lack a single identifiable creator. The design of Jhumkas is deeply rooted in ancient temple sculptures and flourished during the Chola dynasty. Which of the statements given above is/are correct? (a) 1 and 2 only (b) 3 only (c) 2 and 3 only (d) 1, 2 and 3 Correct Solution: C Statement 1 is incorrect because the origin of the Jhumka dates back significantly further than the Mughal era. It is traced to around 300 BCE, with its roots in South Indian temple traditions. Statement 2 is correct. Heritage crafts like Jhumkas, Bandhani, or Chikankari are collective traditions passed down through generations.

• Question 4 of 10 4. Question 1 points In the context of Electronic Warfare, consider the following: Statement-I: GPS spoofing is considered more dangerous and sophisticated than GPS jamming. Statement-II: While jamming simply drowns out satellite signals with noise, spoofing deceives a receiver into calculating a false location. Which one of the following is correct in respect of the above statements? (a) Both Statement-I and Statement-II are correct and Statement-II is the correct explanation for Statement-I (b) Both Statement-I and Statement-II are correct and Statement-II is not the correct explanation for Statement-I (c) Statement-I is correct but Statement-II is incorrect (d) Statement-I is incorrect but Statement-II is correct Correct Solution: A Statement-I is correct. GPS spoofing is more dangerous because the operator of the vessel or aircraft may not immediately realize the navigation data is compromised. In contrast, jamming creates a “denial of service” where the receiver simply stops working, alerting the operator to switch to manual navigation. Statement-II is the correct explanation for Statement-I. Jamming works by broadcasting high-power radio frequency noise on the L1 and L2 bands, effectively “blinding” the receiver. Spoofing, however, involves transmitting a fake GNSS signal that mimics the real one but with slight timing offsets. This leads the receiver to believe it is elsewhere—for example, a ship in the Strait of Hormuz might appear to be at an inland location. This deception can lead to fatal navigational errors or luring vessels into hostile waters, making it a highly sophisticated tool of modern electronic warfare.

• Question 10 of 10 10. Question 1 points Consider the following statements regarding the geographical features of the Gulf region: The Persian Gulf is characterized by deep oceanic trenches that make it unsuitable for offshore drilling. Wadis are intermittent river valleys that remain dry for most of the year. The region experiences extreme heat, with temperatures occasionally exceeding 50°C. How many of the above statements are correct? (a) Only one (b) Only two (c) All three (d) None Correct Solution: B Statement 1 is incorrect. The Persian Gulf is actually a shallow marginal sea, which is exactly what makes it an ideal environment for offshore oil and gas drilling. Its gentle slope and shallow waters allow for easier extraction compared to deep-sea oceanic regions. Statement 2 is correct. Wadis are a defining feature of the arid Arabian landscape; they are valleys that may flash flood during rare heavy rains but are otherwise dry. Statement 3 is correct. The climate is extremely arid and hot, with summer temperatures frequently crossing the 50°C mark, necessitating advanced cooling infrastructure and making water security (via desalination) a top priority for GCC nations. The combination of this harsh climate and the unique geology—the stable Arabian Shield and the sedimentary lowlands—defines the socio-economic and strategic profile of the Gulf nations. Incorrect Solution: B Statement 1 is incorrect. The Persian Gulf is actually a shallow marginal sea, which is exactly what makes it an ideal environment for offshore oil and gas drilling. Its gentle slope and shallow waters allow for easier extraction compared to deep-sea oceanic regions. Statement 2 is correct. Wadis are a defining feature of the arid Arabian landscape; they are valleys that may flash flood during rare heavy rains but are otherwise dry. Statement 3 is correct. The climate is extremely arid and hot, with summer temperatures frequently crossing the 50°C mark, necessitating advanced cooling infrastructure and making water security (via desalination) a top priority for GCC nations. The combination of this harsh climate and the unique geology—the stable Arabian Shield and the sedimentary lowlands—defines the socio-economic and strategic profile of the Gulf nations.

#### 10. Question

Consider the following statements regarding the geographical features of the Gulf region:

• The Persian Gulf is characterized by deep oceanic trenches that make it unsuitable for offshore drilling.
