阅读理解。 There are thousands of products of all colors and shapes in a supermarket,making you believe that they are worth a try.How? Packaging (包装) is the silent but persuading salesman. There on the shelves,each bottle,can,box,and jar has been carefully designed and measured to speak to the inner self of  the consumer (消费者), because he is buying not only a product but also his belief in life. Scientists  have studied consumer  behavior recently and  found  that  the look of the package has a great effect on the 'quality'  of the product and on how well it sells,because 'Consumers  generally  cannot tell between a product and its package. Many products are packages and many packages are products',as Louis Cheskin,the first social scientist studying consumers' feelings for packaging,noticed. Colors are one of the best tools in packaging.Studies of eye movement have shown that colors draw human attention quickly.Take V8 for example.For many years,the bright red color of tomatoes and carrots on the thin bottle makes you feel that it is very good for your body.And the word 'green' today can keep food prices going up. Shapes are another attraction.Circles often suggest happiness and peacefulness,because these shapes are pleasing to both the eye and the heart.That's why the round yellow M signs of McDonald's are inviting to both young and old. This new consumer response  (反应)  to the colors and shapes of  packages  reminds  producers and sellers that people buy to satisfy both body and soul. 1.According to the passage, ________ seems to be able to persuade a consumer to buy the product.
