Understand the pattern
Yes/No questions: move be before the subject (“Is the parade colourful?”); with ordinary present verbs use Do/Does + subject + base verb (“Do people wear costumes?”); in the past use Did + base verb (“Did you join?”). Short answers repeat the auxiliary: Yes, they do; No, she did not. Do not answer “Yes, I am” to “Do you…?”. Give accurate cultural information without treating all communities as identical.
