Question 1

Rare Earth Elements (REEs) are called 'rare' because they are scarce in the Earth's crust.

Accepted Answer

They are relatively abundant globally but are rarely found in concentrated, economically viable ores. They often occur mixed with radioactive elements like thorium or uranium, making extraction and refining difficult and highly toxic.

Question 2

China completely monopolizes the natural reserves of Rare Earth Elements globally.

Accepted Answer

While China has the largest reserves, countries like Brazil possess massive deposits (approx. 21 million tons, the world's second-largest). China's monopoly lies in the processing, refining, and metallurgical capacities it built over decades.

Question 3

Consider the following statements regarding the critical minerals cooperation between India and Brazil:
1. Brazil possesses the world's largest known reserves of Rare Earth Elements (REEs).
2. The 2026 MoU specifically incorporates the use of Artificial Intelligence for geoscientific data analysis to aid mineral exploration.
3. The National Critical Mineral Mission, approved by the Indian Cabinet in January 2025, aims to build domestic capacity across the mineral value chain.
How many of the above statements are correct?

Accepted Answer

(b) Only two — Statement 1 is incorrect because China holds the world's largest reserves of REEs; Brazil holds the second-largest reserves (approximately 21 million tons). Statement 2 is correct as the MoU includes provisions for AI in geoscientific analysis, signed concurrently with the 2nd AI Impact Summit. Statement 3 is correct as the National Critical Mineral Mission was approved in January 2025 to run until 2030-31.

Question 4

Match List I (Initiative/Entity) with List II (Context) in the backdrop of India's mineral security:
List I
A. Pax Silica
B. KABIL
C. ANVISA
D. National Critical Mineral Mission

List II
1. State-backed Indian joint venture for overseas mineral acquisition
2. US-led initiative joined by India for securing the semiconductor supply chain
3. Brazilian regulatory agency involved in the 2026 bilateral MoUs
4. Domestic initiative launched to accelerate end-of-life recovery and processing

Select the correct answer using the code given below:

Accepted Answer

(a) A-2, B-1, C-3, D-4 — Pax Silica (A) is the US-led initiative for the silicon stack that India joined in Feb 2026 (A-2). KABIL (B) is Khanij Bidesh India Ltd., tasked with sourcing critical minerals abroad (B-1). ANVISA (C) is Brazil's health surveillance agency which signed a pharmaceutical MoU with CDSCO (C-3). The National Critical Mineral Mission (D) focuses on domestic mining and recycling capacity (D-4).

Question 5

Assertion (A): The signing of the India-Brazil Critical Minerals MoU strengthens India's bargaining power in the global mineral market, reducing its vulnerability to unilateral export restrictions.
Reason (R): Brazil recently became a signatory to the US-led Pax Silica initiative, establishing a legally binding mineral supply corridor to member states like India.
Select the correct answer:

Accepted Answer

(c) A is correct but R is not correct — Assertion (A) is true because diversifying sources by partnering with resource-rich nations like Brazil reduces India's dependence on Chinese processing monopolies, thereby enhancing its leverage. Reason (R) is false because Brazil is NOT a member of the Pax Silica initiative; the India-Brazil MoU is a standalone, non-binding bilateral agreement between two Global South nations.
