سؤال إنجليزي للصف التاسع في القراءة والاستيعاب

In many supermarkets, the main entrance leads directly into the fruit and vegetable section. Psychologists say that when we start by buying food which is good for us, we are more likely to feel better about ourselves. That's why, later on, we often take a packet of biscuits as a reward for our earlier good behaviour. Supermarket managers also want customers to look at as many products as possible. That's why key products such as dairy, bread and meat are right at the back of the store.
