Explanation:

- The idiom "had a close shave" means narrowly avoiding something dangerous or disastrous.

- Option 1: nothing to eat – This suggests scarcity of food, which doesn't fit the idiom's meaning.

- Option 2: a narrow escape – This is the correct meaning of the idiom, indicating just barely getting away from danger.

- Option 3: to have no livelihood – This implies loss of job or means to earn, which is not what "close shave" indicates.

- Option 4: to lose all possessions – While dangerous situations can lead to this, "close shave" specifically means narrowly avoiding disaster, not the aftermath.
