Passage Summary: Banks process millions of transactions, but if they accidentally put a big pile of money in your account, their internal checks are almost certainly going to catch the mistake.

Conclusion: It is highly probable that a bank's internal audit will detect an accidental large credit to a customer's account.

Reasoning: The claim is presented as a likely outcome despite the massive volume of daily transactions handled by modern banks.

Analysis: This is a 'Strengthen' question for a standalone claim. We need to find a reason why these audits are so reliable, especially for large amounts. Look for an answer that explains the 'how'—perhaps that banks are required to balance their total assets every day, or that large, unusual deposits trigger an automatic red flag in the system. The more we know about why the system is 'unlikely' to fail, the more supported the claim becomes.
