1. Present simple tense: Used throughout the answer (e.g., "National Day is...", "It marks...", "people often travel...") to state facts and describe regular events, which is appropriate for talking about festivals.
2. Passive voice: "is celebrated with a week-long holiday" uses the passive voice to focus on the event rather than who is celebrating it, making the answer sound more formal and objective.
3. Parallel structure: "travel, visit family, or take part in public events and parades" uses parallel verbs to list common activities, making the sentence clear and easy to follow.
4. Descriptive phrases: Phrases like "national pride and celebration" and "the whole country really comes alive" add vividness and emotion to the answer, making it more engaging.
