The idiom "to turn a blind eye" means to deliberately ignore something or pretend not to notice a situation, especially something undesirable or problematic.
Let's analyze the given options to determine which one uses the idiom correctly:
- She turned a blind eye to the bright sunlight and put on her sunglasses. - This sentence uses the idiom incorrectly because putting on sunglasses in response to sunlight does not imply ignoring anything.
- He turned a blind eye when he missed the road sign. - This sentence uses the idiom incorrectly as missing a road sign typically involves not seeing it, rather than ignoring it intentionally.
- The manager turned a blind eye to the employee’s repeated tardiness. - This sentence correctly uses the idiom because it suggests that the manager is consciously choosing to ignore the issue of the employee being repeatedly late.
- She turned a blind eye to read the fine print on the contract. - This sentence uses the idiom incorrectly; reading fine print doesn't involve ignoring something intentionally.
Therefore, the correct sentence is: The manager turned a blind eye to the employee’s repeated tardiness.
