Regular Verbs in the Past Tense

Regular verbs follow a specific pattern when forming the past tense. They typically add the suffix "-ed" to the base form of the verb to indicate past tense. In the given options, the regular verb in the past tense is "walked."

Explanation:

Regular verbs in the past tense follow a consistent pattern, regardless of the verb's base form. Let's analyze each option to determine which one is a regular verb in the past tense.

1. Take: The base form of the verb is "take." To form the past tense, we add the suffix "-ed." However, "took" is the correct past tense form of "take," making it an irregular verb.

2. Go: The base form of the verb is "go." To form the past tense, we add the suffix "-ed." However, "went" is the correct past tense form of "go," making it an irregular verb.

3. Run: The base form of the verb is "run." To form the past tense, we add the suffix "-ed." However, "ran" is the correct past tense form of "run," making it an irregular verb.

4. Walked: The base form of the verb is "walk." To form the past tense, we add the suffix "-ed." The correct past tense form of "walk" is indeed "walked," making it a regular verb.

Therefore, option D, "walked," is the correct answer as it is a regular verb in the past tense. The other options (take, go, run) are irregular verbs as they do not follow the typical "-ed" pattern to form the past tense.
