Questions 21-25 Apple is hardly alone in the high-tech industry when it comes to duff gadgets and unhelpful call centers, but in other respects it is highly unusual. In particular, it inspires an almost religious fervor among its customers. That is no doubt helped by the fact that its corporate biography is so closely bound up with the mercurial Mr. Jobs, a rare showman in his industry. Yet for all its flaws and quirks, Apple has at least four important wider lessons to teach other companies. The first is that innovation can come from without as well as within. Apple is widely assumed to be an innovator in the tradition of Thomas Edison or Bell Laboratories, locking its engineers away to cook up new ideas and basing products on their moments of inspiration. In fact, its real skill lies in stitching together its own ideas with technologies from outside and then wrapping the results in elegant software and stylish design. The idea for the iPod, for example, was originally dreamt up by a consultant whom Apple hired to run the project. It was assembled by combining off-the-shelf parts with in-house ingredients such as its distinctive, easily used system of controls. And it was designed to work closely with Apple’s iTunes jukebox software, which was also bought in and then overhauled and improved. Apple is, in short, an orchestrator and integrator of technologies, unafraid to bring in ideas from outside but always adding its own twists. This approach, known as "network innovation", is not limited to electronics. It has also been embraced by companies such as Procter ＆ Gamble, BT and several drugs giants, all of which have realized the power of admitting that not all good ideas start at home. Making network innovation work involves cultivating contacts with start-ups and academic researchers, constantly scouting for new ideas and ensuring that engineers do not fall prey to "not invented here" syndrome, which always values in-house ideas over those from outside. Second, Apple illustrates the importance of designing new products around the needs of the user, not the demands of the technology. Too many technology firms think that clever innards are enough to sell their products, resulting in gizmos designed by engineers for engineers. Apple has consistently combined clever technology with simplicity and ease of use. The iPod was not the first digital-music player, but it was the first to make transferring and organizing music, and buying it online, easy enough for almost anyone to have a go. Similarly, the iPhone is not the first mobile phone to incorporate a music-player, web browser or e-mail software. But most existing "smartphones" require you to be pretty smart to use them. Apple is not alone in its pursuit of simplicity. Philips, a Dutch electronics giant, is trying a similar approach. Niklas Zennstrom and Janus Friis, perhaps the most Jobsian of Europe’s geeks, took an existing but fiddly technology, internet telephony, to a mass audience by making it simple, with Skype; they hope to do the same for internet television. But too few technology firms see "ease of use" as an end in itself. Which of the following item is NOT the correct statement of "network innovation"

A. Innovation to improve network performance.
B. Ideas are brought from outside and integrated with the company’s own advantage.
C. It is based on the ground that not all good ideas come from home.
D. It involves cultivating contacts with start-ups and academic researchers.
