Помогите пожалуйста ответить на вопросы по тексту.

I write historical novels now. I have always been curious about the past and I have always tried to learn as much as different in those times. People didn’t use to travel in cars and planes. They used to tell the time by the Sun. They didn’t use to buy so much food but grew most of it themselves. Yes, life used to be different many years ago. 5. What has she always been curious about? 6. Why does Mary say that life used to be different many years ago?
