Then our four-member group had a 3 and decided to do some research in a supermarket. Two of us wrote down the names of the 4 food on the shelves. The other two asked 5 some questions like "Do you know what green food is?" "How often do you 6 green food?" and so on. More than 30 customers 7 our questions! Later each group in our class wrote a research report 8 the topic and handed it in. Our teacher chose the 9 ones and put them up on the wall of the classroom. 10 was among them!
