Final answer:
An inherent weakness of the European Union is that stronger countries may have to rescue weaker ones in financial crisis.
Step-by-step explanation:
True, an inherent weakness of the European Union is that stronger countries may have to rescue weaker ones that are in financial crisis. This was evident during the financial crisis that occurred in Europe, where countries like Greece, Ireland, Spain, and Portugal faced severe austerity measures and had to rely on financial assistance from stronger EU countries to address their economic challenges. The bailouts provided by stronger countries contributed to the accumulation of high deficits and raised questions about the viability of the euro as the common currency in the EU.
