Explanation:

In this passage, we need to put the verbs in brackets into the correct tense. Let's go through each sentence and determine the correct tense for each verb.

1) (shop) - This verb refers to an action that happened in the past, so it should be in the past continuous tense. The correct form is "was shopping".

2) (leave) - This verb also happened in the past, so it should be in the past simple tense. The correct form is "left".

3) (put) - This verb happened before the action of leaving the purse, so it should be in the past perfect tense. The correct form is "had put".

4) (be) - This verb refers to a general state of being in the past, so it should be in the past simple tense. The correct form is "was".

5) (give) - This verb happened after the man found the purse, so it should be in the past simple tense. The correct form is "gave".
