Question 1 of 5
1. Question
Q.1) Consider the following statements regarding the Cell Broadcast System (CBS) launched in India on May 2, 2026:
- CBS is a telecom-enabled public warning system that broadcasts simultaneous, geo-targeted alerts to mobile devices within a defined area using a one-to-many channel.
- CBS alerts cannot be disabled by users and work across 2G to 5G networks without requiring an internet connection.
- CBS complements the existing SACHET SMS-based system, with CBS designed for time-critical emergencies (tsunamis, earthquakes) where seconds matter.
Which of the statements given above is/are correct?
Correct
Q.1) Solution (d)
Explanation:
All three statements are correct.- CBS was developed indigenously by C-DOT (Centre for Development of Telematics) in collaboration with NDMA and MHA.
- It delivers alerts in near real-time without queuing delays, with geo-targeting precision at individual cell tower level, and is immune to network congestion.
- CBS works across 2G to 5G networks and does not require an internet connection. Alerts appear as pop-up messages with distinct loud tones that cannot be disabled.
- SACHET (the existing SMS-based system) has disseminated over 134 billion alerts in 19+ languages. CBS is for time-critical emergencies, while SACHET handles general alerts.
- The system aligns with the UN’s “Early Warnings for All” initiative and has been demonstrated in Mauritius, Cambodia, El Salvador, and Sri Lanka. UPSC tests this complementarity.
Why this question?
Tests the key features and complementarity of CBS with SACHET – a current disaster management initiative.Why important for UPSC?
Disaster management and early warning systems appear in Geography and Governance (Prelims 2024, 2026 trend).Incorrect

Question 2 of 5
2. Question
Q.2) Assertion (A): The ₹92,000-crore Great Nicobar project, featuring an International Container Transshipment Terminal (ICTT) at Galathea Bay and a greenfield airport, is strategically vital for monitoring the Strait of Malacca and countering China’s ‘String of Pearls’ strategy.
Reason (R): The project received clearance from the National Green Tribunal (NGT) in February 2026, which noted that considering the strategic importance of the project, no good ground was found to interfere.Select the correct answer using the codes given below:
Correct
Q.2) Solution (b)
Explanation:
Both A and R are true, but R is not the explanation of the strategic importance – it only confirms legal clearance.- Great Nicobar Island is located just 150 km from the Strait of Malacca, through which approximately 80% of China’s oil imports pass.
- The project will provide India with enhanced domain awareness and counter China’s ‘String of Pearls’ (Gwadar, Hambantota, Kyaukpyu).
- The NTG on February 16, 2026, cleared the project, directing authorities “to ensure full and strict compliance of EC (environment clearance) conditions”.
- Why R is NOT the correct explanation of A:
The NGT’s clearance is a legal/environmental validation, not the reason for the project’s strategic importance. Strategic importance arises from geography and geopolitics, not from judicial approval. - However, the project faces criticism from environmentalists and tribal rights activists (Shompen and Great Nicobarese tribes). The government claims no displacement of indigenous communities.
Why this question?
Tests the strategic rationale for Great Nicobar project (Malacca Strait monitoring) vs its legal clearance – a high-level IR and Environment question.Why important for UPSC?
Strategic infrastructure and India’s Act East Policy appear in Security and IR (Prelims 2024, 2026 trend).Incorrect

Question 3 of 5
3. Question
Q.3) Consider the following statements regarding the legal and historical basis of the India-Nepal border dispute over Lipulekh Pass:
- Nepal bases its claim on the Treaty of Sugauli (1816), which established the Kali River (Mahakali) as Nepal’s western boundary.
- India argues that Lipulekh has been used for the Kailash Mansarovar Yatra since 1954 and that Nepal’s claims are “untenable” and “unilateral artificial enlargement of territorial claims”.
Which of the statements given above is/are correct?
Correct
Q.3) Solution (c)
Explanation:
- Statement 1 is correct: Treaty of Sugauli (1816) ended the Anglo-Nepalese War (1814-1816) and established the Kali River as Nepal’s western boundary. Nepal claims the river originates at Limpiyadhura , placing Lipulekh and Kalapani on Nepal’s side.
- Statement 2 is correct: India maintains Lipulekh has been used for the Kailash Mansarovar Yatra since 1954 and calls Nepal’s claims “untenable” and “unilateral artificial enlargement”. UPSC tests this non-recognition fact.
Why this question?
Tests the current status of Nepal’s map (not recognised by India) – a common factual trap.Why important for UPSC?
India-Nepal bilateral relations and border disputes appear in IR (Prelims 2018, 2020, 2022, 2024).Incorrect

Question 4 of 5
4. Question
Q.4) Consider the following statements regarding BRO Project Deepak, which celebrated its 66th Raising Day on May 4, 2026:
- Project Deepak was established in 1961 and is responsible for maintaining approximately 1,100 km of roads in Himachal Pradesh (Shimla, Kinnaur, Kullu, Lahaul-Spiti).
- The project maintains the historic Hindustan–Tibet Road and the strategic Manali–Leh axis, critical for defence logistics.
- In May 2023, Project Deepak rescued approximately 300 motorists at Baralachala Pass, and in July 2023, evacuated around 250 civilians from Chandrataal.
Which of the statements given above is/are correct?
Correct
Q.4) Solution (c)
Explanation:
All three statements are correct.- Project Deepak is one of BRO’s oldest projects, established in 1961.
- It is responsible for maintaining approximately 1,100 km of roads in Himachal Pradesh (Shimla, Kinnaur, Kullu, Lahaul-Spiti).
- Key roads include the historic Hindustan–Tibet Road and the strategic Manali–Leh axis, which is critical for defence logistics to border areas.
- The Border Roads Organisation (BRO) was established in 1960. Project Deepak has a dual role – infrastructure development and humanitarian assistance / disaster management.
- In May 2023, it rescued ~300 motorists at Baralachala Pass , and in July 2023, it evacuated ~250 civilians from Chandrataal.
- This demonstrates BRO’s role beyond border infrastructure. UPSC tests this dual-role fact.
Why this question?
Tests the disaster management role of BRO – a lesser-known but important function.Why important for UPSC?
Border infrastructure and disaster management appear in Geography and Security (Prelims 2019, 2021, 2023, 2024).Incorrect

Question 5 of 5
5. Question
Q.5) Consider the following statements:
- NASM-SR features a ‘man-in-loop’ guidance system allowing real-time operator control via a two-way data link, unlike older ‘fire-and-forget’ missiles.
- The Outer Space Treaty (1967) prohibits the placement of nuclear weapons in orbit but does not ban conventional weapons in space.
- The Viasat KA-SAT cyber attack (2022) demonstrated how a civilian satellite network could be weaponised by crippling communications across Europe.
- The Cell Broadcast System (CBS) in India is based on the Common Alerting Protocol (CAP) and has already been demonstrated in Mauritius, Cambodia, El Salvador, and Sri Lanka.
Which of the statements given above is/are correct?
Correct
Q.5) Solution (b)
Explanation:
- Statement 1 is correct: NASM-SR’s man-in-loop guidance allows real-time trajectory modification, unlike fire-and-forget missiles.
- Statement 2 is correct: Outer Space Treaty (1967) – Article IV prohibits placing nuclear weapons or WMDs in orbit but does not prohibit conventional weapons in space.
- Statement 3 is correct: The Viasat KA-SAT cyber attack (initial hours of Russia-Ukraine War, 2022) crippled civilian internet and military communications across Europe.
- Statement 4 is incorrect: The Cell Broadcast System (CBS) is not based on Common Alerting Protocol (CAP) – it is a separate one-to-many broadcast system. SACHET (the existing SMS-based system) is based on CAP and has disseminated over 134 billion alerts. CBS complements SACHET. CBS has been demonstrated internationally (Mauritius, Cambodia, El Salvador, Sri Lanka) – that part is correct, but the CAP attribution is wrong. UPSC tests this protocol distinction.
Why this question?
Tests the distinction between CBS (not CAP-based) and SACHET (CAP-based) – a high-level factual trap.Why important for UPSC?
