1. Present simple tense: Used throughout the answer (e.g., "families tend to keep," "albums often get passed down") to talk about general truths and habits, which is appropriate for this type of question.
2. Relative clauses: "that their parents or even grandparents looked like when they were young" adds detail and complexity, showing the ability to use more advanced sentence structures.
3. Passive voice: "albums often get passed down" uses the passive voice to focus on the albums rather than who is passing them down, which is a natural and effective way to express this idea.
4. Linking ideas: The use of "so" and "and" helps to connect ideas smoothly, making the answer sound natural and cohesive.
