Which statement best explains why NRCan designates a mineral as 'critical'?

• A. A mineral essential to modern technology and national security; NRCan assesses supply risk and strategies to ensure domestic access.
• B. A mineral that is extremely rare everywhere and without any industrial use.
• C. A mineral that is abundant and has no supply risk concerns.
• D. A mineral with no strategic importance to technology or security.

Answer: (A)

The idea being tested is that a mineral is designated as critical because it is essential for modern technology and national security, and there are real concerns about its supply. NRCan designates a mineral as critical when it plays a key role in high-tech and defense applications, and when the risk of disrupted or unreliable supply could threaten the economy or security. The statement you chose reflects that by noting its importance to technology and national security and by pointing to NRCan’s role in assessing supply risk and developing strategies to ensure domestic access. The other options don’t fit because they either assume rarity with no use, or claim abundance with no risk, or deny any strategic value—none of which align with the concept of a critical mineral being both strategically important and subject to supply risk that warrants government action.
