Step 1: Identify the tense signal. 'Every day' shows this is a habitual routine. Habitual actions use the simple present tense. Step 2: Identify the subject. 'Ahmad' is a singular third-person subject (he). In simple present tense, add '-s' to the base verb for he/she/it subjects. Step 3: Apply the rule to both verbs. 'wake' + '-s' = 'wakes'. 'walk' + '-s' = 'walks'. Step 4: Both verbs must be consistent — same tense, same subject-verb agreement rule applied to every verb in the sentence. Answer: wakes / walks
