hoàn thành các câu sau theo đúng ngữ pháp

Dưới đây là câu hoàn chỉnh: 2. I went home while my mother was cooking dinner. 3. I made the cake when my mother was reading books. Tôi cũng hoàn thành câu 1 vì bạn không cung cấp: 1. Tôi sẽ giả sử câu 1 là: "I (go) to the store when my father was watching TV." -> 1. I went to the store when my father was watching TV.
