The recent increase in global food prices is primarily a result of speculative trading on commodity markets, rather than fundamental shifts in supply or demand. Large financial institutions, betting on price fluctuations, create artificial demand and volatility, driving up the cost of essential foodstuffs. Therefore, governments should implement stricter regulations on financial speculation in food commodities to stabilize prices and ensure food security for vulnerable populations.
Correct: A
The argument concludes that governments should implement stricter regulations on financial speculation in food commodities, based on the premise that speculative trading is the *primary cause* of the increase in global food prices. To weaken this argument, we need to show that speculation is not the primary cause, or that the proposed solution has significant negative unintended consequences.
Option (A) directly attacks the premise that speculative trading is the *primary* cause by offering a powerful alternative explanation: 'significant disruptions due to climate change and regional conflicts'. If fundamental supply issues are widespread and significant, they could be the primary drivers of price increases, not speculation. This weakens the argument by undermining its core causal claim.
(B) This points to a practical difficulty in implementing the solution, but does not weaken the argument that speculation is the *cause* of the problem, or that the solution *would work if implemented*.
(C) This offers *another* alternative cause for food price increases, similar to (A). However, (A) talks about 'significant disruptions' in *production*, which is a more fundamental supply-side issue. Biofuels are a demand-side shift that impacts supply, but (A) covers a broader and perhaps more critical set of disruptions that would strongly challenge the 'primarily a result of speculative trading' claim.
(D) This is a strong argument for an *unintended negative consequence* of the proposed solution. If regulations reduce market liquidity and harm farmers, it significantly weakens the overall proposal. However, (A) directly challenges the *diagnosis of the problem itself*, which is often a more fundamental weakening point. If the diagnosis is wrong, the solution is misdirected.
(E) Similar to (A) and (C), this offers alternative causes. However, 'overall impact is often overshadowed' by other factors like currency and energy costs, suggesting these are more primary. (A) gives specific, recent, impactful causes (climate change, conflicts) that are very compelling as primary drivers of food price increases.
