Lesson3: Presents for mother's day

Read the following statement then answer the question that follows.

“My little sister is 5 years old. She hasn't been very well this month. She had a bad cough and cold. Then she got a rash and had a temperature, too. She was in bed for four days and had to take some medicine. Our mum made her some chicken Soup and she had fruit juice to drink. Dad bought her a pretty new dress. I think it's made from cotton. It's blue and white with pink flowers.”

What’s the material of the dress?
