In Wakanda, the amount of vibranium retrieved every year is just large enough to satisfy the demand of its national weapons industry. Wakanda's mining productivity will not increase in the foreseeable future, nor will new vibranium mines be discovered. Wakanda's weapons industry, however, will be increasingly significant as new companies enter the market. Clearly, Wakanda will soon need to import vibranium.
Which of the following is an assumption on which the argument depends?
(A) No new technologies to economize vibranium will be implemented by weapon manufacturers in Wakanda.
(B) Not all vibranium currently mined-out in Wakanda is of industrial grade.
(C) None of the vibranium mines in Wakanda are exceptionally high-yielding.
(D) There are no other industries in Wakanda that will not increase.
(E) There are no other major metals in Wakanda for which the supply and demand are currently in balance.

To determine which option best represents an assumption underlying the argument, let’s first break down the argument’s structure:
Argument Summary:
1. Current Situation:
• Supply: Wakanda retrieves just enough vibranium each year to meet the demand of its national weapons industry.
• Supply Constraints:
• Mining productivity will not increase in the foreseeable future.
• No new vibranium mines will be discovered.
2. Future Projections:
• Demand: Wakanda’s weapons industry will become increasingly significant as new companies enter the market.
3. Conclusion:
• Implication: Wakanda will soon need to import vibranium to meet the growing demand.
Identifying the Assumption:
An assumption is an unstated premise that must be true for the argument to hold. In this case, the argument hinges on the relationship between constant supply and increasing demand leading to the necessity of imports.
Let’s evaluate each option to see which one is essential for the argument:
• Option A: No new technologies to economize vibranium will be implemented by weapon manufacturers in Wakanda.
Analysis:
• Relevance: If weapon manufacturers develop technologies to use vibranium more efficiently, the demand for vibranium may not increase as significantly. This would undermine the conclusion that imports are necessary.
• Necessity: For the argument to hold, it must be assumed that no such technological advancements will occur. Otherwise, the increased demand might be offset by decreased usage per unit of weaponry.
• Option B: Not all vibranium currently mined in Wakanda is of industrial grade.
Analysis:
• Relevance: This relates to the quality of vibranium but doesn’t directly impact the supply-demand dynamic discussed in the argument.
• Option C: None of the vibranium mines in Wakanda are exceptionally high-yielding.
Analysis:
• Relevance: The argument already states that mining productivity won’t increase, making this option somewhat redundant and not directly addressing the core assumption about demand.
• Option D: There are no other industries in Wakanda that will not increase.
Analysis:
• Relevance: This option is ambiguously worded and doesn’t directly tie into the vibranium supply-demand scenario presented.
• Option E: There are no other major metals in Wakanda for which the supply and demand are currently in balance.
Analysis:
• Relevance: This introduces a new variable unrelated to vibranium’s specific supply and demand dynamics.
Conclusion:
Option A is the most critical assumption for the argument. It directly addresses a factor that could influence the demand for vibranium. If weapon manufacturers were to implement technologies that reduce vibranium usage, the anticipated increase in demand (and thus the need for imports) might not materialize.
Answer:
A. No new technologies to economize vibranium will be implemented by weapon manufacturers in Wakanda.
Argument Summary:
1. Current Situation:
• Supply: Wakanda retrieves just enough vibranium each year to meet the demand of its national weapons industry.
