Question: Did you prefer to do activities alone or with a group of people when you were a child?
You should talk about your preference as a child—whether you liked doing things by yourself or with others. You can also mention the types of activities you enjoyed and why you preferred being alone or in a group.
Try these synonyms instead of repeating the question:
activities→things; tasks; hobbies; games
alone→by myself; on my own; solo
group of people→with others; with friends; in a team
