Question 1 of 15
On 14 September 2026, India and MERCOSUR signed the First Additional Protocol to their 2004 Preferential Trade Agreement, which amends Article 16 of Annex III. What does the amendment actually do?
FACT: The First Additional Protocol amends Article 16 of Annex III (Rules of Origin) so that electronic Certificates of Origin carry the same legal validity as paper certificates. The Protocol was signed at New Delhi in the presence of Uruguay’s Foreign Minister representing MERCOSUR’s pro tempore Presidency.
ANALYSIS: Options (a) and (c) would require a much broader renegotiation, not a single-article amendment; (d) is not what the Protocol addresses. The Protocol enters into force after each party completes its domestic ratification.

📝 Concept Note
MERCOSUR has five full members: Argentina, Brazil, Paraguay, Uruguay and Bolivia, which completed its accession in July 2024; Venezuela has been suspended since 2016. India’s signatory to the Protocol was Commerce Secretary Rajesh Agrawal.
The same day, India and MERCOSUR launched negotiations to expand the PTA.

| ⚠️ Common Mistake | ** Treating MERCOSUR as a Free Trade Area; it is a customs union with a common external tariff. ** |
| 📌 Exam Tip | ** The Protocol takes effect after domestic ratification, not on signature. ** |
| 🎤 Interview | ** Why does an electronic Certificate of Origin need a treaty amendment, and not just a regulatory change? |
Question 2 of 15
Which of the following statements about MERCOSUR is CORRECT?
FACT: MERCOSUR is a customs union founded by Argentina, Brazil, Paraguay and Uruguay under the Treaty of Asuncion in 1991 (Bolivia became the fifth full member in 2024) and formalised institutionally by the 1994 Protocol of Ouro Preto. The pro tempore Presidency rotates every six months among the full members.
Uruguay currently holds it. Venezuela has been suspended since 2016.
ANALYSIS: The Treaty of Asuncion (1991) is the founding instrument; Ouro Preto (1994) is the institutional protocol; the two are complementary.

Question 3 of 15
Mazagon Dock Shipbuilders Limited (MDL), which signed a Rs 27,000 crore MoU on 15 September 2026 for a greenfield shipbuilding cluster at Dighi, Raigad, is a Defence Public Sector Undertaking under which Union ministry?
FACT: MDL is a Defence Public Sector Undertaking (DPSU) under the Ministry of Defence. Its primary role is warship and submarine construction, including the Kalvari-class submarines under Project 75 and the Visakhapatnam-class destroyers under Project 15B. The Dighi cluster MoU was signed with National Shipbuilding and Heavy Industries Park Maharashtra Limited (NSHIPML), a special-purpose company set up jointly by the Maharashtra Maritime Board and the Mumbai Port Authority.
ANALYSIS: The Ministry of Ports, Shipping and Waterways handles commercial shipping and ports; MDL’s naval-yard role places it under the MoD.

Question 4 of 15
An SEZ unit approval for SiCSem Private Limited’s silicon-carbide facility at Khordha, Odisha, with investment revised to Rs 3,406.25 crore, was announced on 15 September 2026. What is distinctive about this unit, first approved under the India Semiconductor Mission in August 2025?
FACT: The SiCSem facility at IDCO Infovalley-II, Khordha, is India’s first commercial silicon-carbide (SiC) semiconductor fab, targeting 4.8 million SiC diodes and 91.2 million SiC MOSFETs a year. SiC is a compound semiconductor (a crystalline combination of silicon and carbon) with a wide bandgap of about 3.26 eV, versus silicon’s 1.12 eV, used in EV traction inverters, solar inverters, fast chargers and grid equipment.
ANALYSIS: Existing Indian projects like Tata-PSMC at Dholera and Micron at Sanand are silicon-based; SiCSem is distinguished by its compound-semiconductor focus.

📝 Concept Note
The Union Cabinet approved the unit under the India Semiconductor Mission in August 2025 at about Rs 2,066 crore; the 2026 approval by the 217th Unit Approval Committee (Falta SEZ) is for the SEZ unit. Revised investment Rs 3,406.25 crore, employment about 1,270, plot 21.89 acres, projected five-year exports about Rs 7,043 crore.

| 🎤 Interview | ** Why is a SiC fab a strategic addition beyond a silicon fab? |
Question 5 of 15
Which of the following statements about silicon-carbide (SiC) semiconductor devices is INCORRECT?
FACT: SiC devices are used mainly in power electronics (EV traction inverters, solar and grid inverters, fast chargers, industrial motor drives), not in memory or CPU logic, which remain silicon’s stronghold. The wide bandgap gives SiC higher voltage tolerance, higher operating temperature and higher switching frequency, which together improve efficiency in power stages.
ANALYSIS: The trap here is treating SiC as a general-purpose successor to silicon; it is a power-electronics workhorse.

Question 9 of 15
The Kigali Amendment to the Montreal Protocol, whose tenth anniversary falls in October 2026, adds which class of chemicals to the phase-down list?
FACT: The Kigali Amendment, adopted in October 2016 in Kigali, Rwanda, and in force since 1 January 2019, adds hydrofluorocarbons (HFCs) to the phase-down list. HFCs are not ozone-depleting substances but potent greenhouse gases, with global warming potentials hundreds to thousands of times that of carbon dioxide.
ANALYSIS: CFCs, HCFCs and methyl bromide were addressed in earlier amendments; HFCs entered the Protocol’s remit only with Kigali.

Question 10 of 15
India’s India Cooling Action Plan (ICAP), referenced on World Ozone Day 2026, was released in which year, and what is its distinctive feature?
FACT: ICAP was released in March 2019. India was the first country in the world to release a comprehensive national cooling action plan.
It sets a 20-year outlook (2017-18 to 2037-38) with targets to reduce cooling demand by 20-25 per cent, refrigerant demand by 25-30 per cent, and cooling energy requirements by 25-40 per cent. It also targets certification of 100,000 servicing technicians.
ANALYSIS: India ratified the Kigali Amendment in September 2021, after ICAP; the plan preceded ratification.
