The three principal parts of those verbs are

tell, told, told
catch, catch, caught
know, knew, known

Remember the first principal part is used with the present and future tenses.
The second principal part is used with the past tense.
The third principal part is used with the "perfect" tenses... with the "helping verbs" have,has or had

Sure! Here are the correct tenses for the verbs in the brackets:

1. Soni told us a secret. (past tense of "tell")

To determine the correct tense, we look at the context of the sentence. Since the sentence doesn't specify a particular time in the past, we use the simple past tense "told" to match with the subject "Soni."

2. Did they catch the thief? (past tense of "catch")

In this question, we use the past tense "did" to indicate that the action of catching the thief occurred in the past. We use the base form of the verb "catch" without '-ed' because "did" already indicates the past tense.

3. We have known them for twelve years. (present perfect tense of "know")

The sentence includes the auxiliary verb "have" followed by the past participle form of the main verb "know." With the time expression "for twelve years," we use the present perfect tense to show that the action of knowing began in the past and continues up to the present.

Remember, verb tenses help convey the time when an action occurred, and understanding the context of the sentence is crucial in selecting the correct tense.
