Q1:
With reference to the evolution of cellular wireless networks, consider the following statements: Which of the statements given above are correct?
A: 1 and 2 only
B: 2 only
C: 2 and 3 only
D: 1, 2, and 3
Answer: A
Explanation:
Statement 1 is correct: The primary focus shifts progressively between generations. 4G mainly targets mobile broadband for smartphones. 5G expands into the Internet of Things (IoT), automation, and smart cities. 6G shifts the focus toward "Intelligent Connectivity" by embedding native Artificial Intelligence directly into the architecture.
Statement 2 is correct: Latency (the network response delay) undergoes substantial reduction. 4G features a latency of ~30–50 ms. 5G drops this down to around 1 ms (critical for real-time automation). 6G targets extreme sub-millisecond or microsecond response times to support instant feedback systems.
Statement 3 is incorrect: The data speed parameter for 5G is incorrectly stated. According to the standard architectural metrics, 4G speeds reach up to ~1 Gbps. 5G increases that peak capacity up to ~10–20 Gbps. 6G steps further into the future with potential speeds touching the Terabit per second (Tbps) spectrum.
Q2:
Consider the following statements regarding the Dedicated Freight Corridors (DFCs) in India: Which of the statements given above are correct?
A: 1 and 2 only
B: 1 and 3 only
C: 2 and 3 only
D: 1, 2, and 3
Answer: A
Explanation:
Statement 1 is correct: The Eastern DFC spans major regions of northern and eastern India with a key focus on coal and bulk freight. In contrast, the Western DFC runs through northern and western regions, specializing in container traffic and EXIM (Export-Import) cargo connectivity to western ports.
Statement 2 is correct: The route of the Western Dedicated Freight Corridor (WDFC) is designed from Dadri (Uttar Pradesh) to JNPT (Maharashtra), linking the northern industrial hinterland directly with major western maritime ports.
Statement 3 is incorrect: The Dedicated Freight Corridor Corporation of India Limited (DFCCIL) is a special purpose vehicle created to build, maintain, and operate the DFCs, but it operates under the Ministry of Railways, not the Ministry of Ports, Shipping and Waterways.
Q3:
With reference to the recent developments in India's logistics and railway infrastructure, consider the following statements: Which of the statements given above are correct?
A: 1 and 2 only
B: 1 and 3 only
C: 2 and 3 only
D: 1, 2, and 3
Answer: D
Explanation:
Statement 1 is correct: Prime Minister Narendra Modi inaugurated the final remaining critical links of the WDFC (such as sections near Saphale, JNPT, and Sanand), marking a major milestone where the core national DFC network became fully operational across more than 2,800 km.
Statement 2 is correct: Key engineering highlights of the WDFC include capabilities for running double-stack container trains and managing heavier axle loads at higher speeds, which diverts heavy freight traffic away from shared passenger lines.
Statement 3 is correct: To further expand the heavy-haul rail network beyond the major north-south/east alignments, the Union Budget proposed the Dankuni–Surat East-West Dedicated Freight Corridor to scale up multimodal logistics integration.
Q4:
Consider the following statements regarding the institutional framework of India’s space sector under recent reforms: Which of the statements given above is/are correct?
A: 1 and 2 only
B: 1 and 3 only
C: 2 and 3 only
D: 1, 2, and 3
Answer: C
Explanation:
Statement 1 is incorrect: ISRO does not focus primarily on commercialisation. Its core mandate under the new framework is advanced research and development (R&D), planetary exploration, space science, and strategic national missions.
Statement 2 is correct: IN-SPACe (Indian National Space Promotion and Authorisation Centre) was established as a single-window nodal agency to act as a friendly interface, permitting and regulating private sector entities to use Indian space infrastructure.
Statement 3 is correct: NSIL (NewSpace India Limited) acts as the commercial arm of the Department of Space, responsible for transferring mature technologies to industry and spearheading commercial user-driven missions.
Q5:
Consider the following statements regarding the Indian Space Research Organisation (ISRO): Which of the statements given above are correct?
A: 1 and 2 only
B: 2 only
C: 2 and 3 only
D: 1, 2, and 3
Answer: A
Explanation:
Statement 1 is correct: ISRO was officially founded on August 15, 1969, superseding its predecessor, INCOSPAR, with a much wider and expanded mandate to harness space technology for national development
Statement 2 is correct: INCOSPAR was established in 1962 under the Department of Atomic Energy (DAE) at the initiative of visionary scientist Dr. Vikram Sarabhai, who is widely regarded as the founding father of the Indian space program.
Statement 3 is incorrect: Although ISRO currently operates under the Department of Space (DOS), it was not brought under it at its inception in 1969. ISRO was initially under the DAE and was transferred to the newly created Department of Space in 1972 (which reports directly to the Prime Minister of India)
