The youth of today are even more looking forward to Apple Corp's products. The iPad is an Apple tablet computer. The device sits somewhere between a laptop and a smart phone, according to Apple's chief executive, Steven P. Jobs, and does certain things better than both of them, like surfing the Web, reading e-books and playing videos. The iPad went on sale on April 3, 2010, and Apple said it had shipped 500,000 units in the first week. The handheld device puts Apple on a direct collision course with the Kindle from Amazon, which Mr. Jobs ever considered as pioneering the category. It is common knowledge that media companies hope the iPad will finally lead to available ways for them to charge for news, books and other materials. The half-inch thick, 1.5-pound device features a 9.7-inch multi-touch screen and is powered by a customized Apple microchip, which is called A4. It has been designed with an exposed screen and without a camera or separate keyboard. The iPad has the same operating system as the iPhone and also has access to its 140,000 applications. The price of the device starts at $499 for the most basic model, with a Wi-Fi wireless connection. More expensive models with more memory and with 3G wireless access will cost $629 to $829, depending on storage size. Because Apple is attempting to popularize a new kind of computing device, acceptance among consumers is expected to be slower than with previous Apple devices. Critics assume that some buyers are waiting for future versions of the iPad to appear, perhaps with a camera or USB ports . On its first day on sale, iPad users downloaded more than one million applications from the company's AppStore and more than 250,000 electronic books from its iBookstore. A new wave of apps is expected in response to the iPad. For an application developer, having an application accepted for a highly desired Apple product means reaching a passionate group of consumers. The potential... Question: It is implied in the passage that _ . - people may download any application from the App Store - the Apple company will make more profit from the iPad - people would prefer to buy an iPad rather than an iPhone - owning an Apple product means that you will be respected
the Apple company will make more profit from the iPad

Read the following article and select the best answer. Article: Dr. Jack M. Gwaltney, Jr. a professor at the University Of Virginia School Of Medicine infected six student volunteers with virus, the most common cause of colds. A few days later, when they were coughing and sneezing, he gathered 37 more people and divided them into three groups. Group 1 members spent three days and nights in the same room with one of the infected students, separated by a screen so they couldn't touch one another. Group 2 sat around a table while an infected volunteer talked, coughed and sang to them. Group 3 held hands with an infected student for ten seconds, and then touched their own noses or eyes. Although most scientists at the time, the mid-70s, believed colds were spread by virus-laden droplets spread through the air when infected people coughed or sneezed, Gwaltney suspected physical contact might play an important role. Sure enough, of the 15 people who had touched a student volunteer, 11 became infected--compared with only one of those who had been sitting at the table, and none who had spent three days and nights together. "The best evidence we have is that hand-to-hand contact is the most efficient way of transmitting virus," says Gwaltney. The study was one of a series that helped establish Gwaltney's reputation as a leading authority. Dr. Robert Couch says, "It would not be inappropriate to call him Mr. Common Cold." When Gwaltney is asked how close scientists are to finding a cure, he replies: "If you mean 'get rid of', I don't think we're going to be able to do that with cold viruses any time soon. But if you look in the dictionary, you'll see that 'cure' is explained as a successful treatment. And we're not just getting more effective at treating the symptoms --we're getting at the root cause too. " Question: The result of the experiment shows that _ plays an important role in the infection of colds. - sneezing at the infected person - touching the infected person - sitting together with the infected person - talking with the infected person
touching the infected person
