Why does the speaker say you should look your best when you go out?

• A. You never know who you might see, so it's best to be prepared for anything.
• B. Appearance is unimportant in public.
• C. You should always dress well for formal events.
• D. Public appearances are unpredictable and you should ignore it.

Answer: (A)

The main idea here is that appearance influences first impressions in real-world, everyday moments, and you want to be ready for anything that might happen when you’re out. You never know who you might encounter—event organizers, photographers, potential sponsors, judges, or people who could influence your opportunities—and presenting yourself neatly and confidently helps you make a positive impression. When you look your best, you signal that you respect others and take things seriously, which can open doors or set a favorable tone for conversations and encounters.

This is why the idea of always looking your best when you go out is supported: it aligns with being prepared for unpredictable public moments and leveraging those moments to your advantage. Saying appearance is unimportant or that you should ignore unpredictability goes against the everyday reality that how you present yourself can matter a lot in spontaneous social interactions, while insisting on formal attire for every outing would be unnecessarily restrictive and not relevant to many typical occasions.
