      "response": "I prefer studying with a small group because I can ask questions when I do not understand an idea. Other students sometimes explain the same topic in a different way, which helps me remember it. Last month, my friends and I prepared a presentation about public transport. I understood the reading, but I was not sure how to organise my part. One friend suggested three main points, and I practised explaining them to the group. Their questions helped me notice where I needed more detail. However, group study is not always efficient. We sometimes talk about unrelated things and lose time. For this reason, I think everyone should prepare alone first and agree on a clear task before meeting. This make our group more useful and gives quieter students time to think.",
