為什麼這兩張圖是一樣的?還有這題要怎麼判斷?

(33.~35.) People in Taiwan never worry about getting hungry at night when there is nothing at home. They can walk to the convenience stores and get anything they I want. In fact, in Taiwan, it is not possible that people fail to find a convenience store because it is part of our life. Convenience stores are working 24/7. In other words, finding a place to sit down and take a rest anytime is a piece of cake. In order to grow business, shopkeepers use some smart ways to have the buyers spend more. First, they put the most popular items at the buyers'eye level to let them see the items easily and often. Second, they drive the buyers to buy something cheap and small without thinking too much or give shoppers a special offer like "Buy One And Get One Free.” Third, they try to have the buyers stay at the convenience stores as long as possible by setting up a seating area. They think the buyers will buy one drink after another once they stay longer. In a study, 73 teenagers answer two of the questions. The pictures below show their interesting answers.
