State the tense of the verb in the passive. (Определи, к какому времени относится глагол в пассивной форме.)

1. The table was painted by the worker. .
2. The letters will be delivered on Friday. .
3. Medicine is kept in this box. .
4. The story was told in details by my sister

1. The verb in the passive form in the first sentence is "was painted." This is in the past tense because it refers to an action that has already happened in the past.

2. The verb in the passive form in the second sentence is "will be delivered." This is in the future tense because it refers to an action that will happen in the future on Friday.

3. The verb in the passive form in the third sentence is "is kept." This is in the present tense because it refers to a general truth or a habitual action that is always true or done in the present.

4. The verb in the passive form in the fourth sentence is "was told." This is in the past tense because it refers to an action that has already happened in the past.

To determine the tense of a verb in the passive form, you need to look at the auxiliary verb (be) and the main verb (past participle form) used in the passive construction. In each sentence, we can identify the tense by examining the auxiliary verb and the main verb.
