The correct answers are A. stalled and F. curb on.
Explanation
- Blank (i): The sentence begins by stating that a long-term investment boom "abruptly reversed." This reversal occurred because the primary driver of lithium demand-the feverish expansion of electric-vehicle manufacturing-unexpectedly A. stalled (stopped making progress or came to a standstill). Intensified is the opposite of what is needed to cause a reversal, and migrated lacks logical sense in this context.
- Blank (ii): The second sentence describes how the high cost of the metal compounded this reversal by "further attenuating" (weakening or reducing) demand. This means the elevated cost acted as a restraint or a F. curb on broader industrial activity. Stimulant for contradicts the negative impact on demand, and prerequisite for is logically unsound, as high costs are a barrier to, not a requirement for, broad industrial growth.
Difficulty Level
Medium. The relationships are straightforwardly signposted by logical markers such as "abruptly reversed" and "further attenuating."
