Artists and designers both create visual works using a/an 1 knowledge background, but their reasons for doing so are 2 different. Some designers consider themselves artists, but few artists consider themselves 3 . So what exactly is the difference between art and design? Perhaps the most fundamental difference that we can all agree on is their 4 . Typically, the process of creating a work of art starts with nothing, a blank sheet of paper. A 5 of art is born from a view or value that the artist holds within himself or herself. They create the art to share that feeling with others, to 6 the viewers to relate to it, learn from it or be 7 by it. The most renowned and successful art today is something that establishes the strongest 8 connection between the artist and their 9 . By contrast, when a designer sets out to 10 a new piece, they almost always have a 11 starting point, whether a message, an image, an idea or an action. The designer’s job isn’t to invent something 12 , but to communicate something that already exists, for a purpose. That purpose is almost always to motivate the audience to do something: buy a product, use a 13 , visit a location, or learn certain information. The most 14 designs are those that most effectively 15 their message and motivate their consumers to carry out a task. 1. A. unique B. separate C. shared D. accepted 2. A. entirely B. occasionally C. hardly D. unnecessarily 3. A. inventors B. designers C. writers D. viewers 4. A. purpose B. product C. interest D. cost 5. A. love B. type C. part D. work
