The following is a new article.  Read it carefully and answer the questions that follow.  Wearing Wireless 1  Doctors want their patients to make fewer visits to their offices. They also want them to stay out of the hospital. This is increasingly possible because of the promising new advances in wireless technology. It is now feasible to provide some forms of health care through small wireless devices that patients can wear. The market for these devices, often called smart apparel, is immense, and it is growing quickly. In 2011, about 14 million of these products were produced at a value of about $2 billion. Experts predict that by 2016, the figures will be closer to 200 million devices and $6 billion. 2  The first devices to be developed have been watches, bracelets, or other types of “jewelry.” Their primary purpose has been to monitor a patient’s basic health indicators, such as blood pressure, heart rate, and breathing rate. They can continuously transmit the information to a patient’s doctor. This kind of information is very important because it can show whether patients are healthy and stable or if they might be heading for trouble. It is particularly valuable to patients with cardiovascular or respiratory diseases, who would have to visit their doctors frequently if they did not have these monitoring devices. Another important group of users is pregnant women. The devices can transmit information about their unborn babies to their doctors. This can help ensure that the babies remain healthy until they are born. 3  More recent devices can monitor a much wider range of indicators. They can measure the level of sugar in a patient’s blood, a patient’s body temperature, and how much energy a patient is using. Like the earlier devices, they can transmit this information to the patient’s doctors, who can assess it from their offices. In this way, doctors become aware of problems before the problems become a danger to the patients. 4  Now the developers of these devices want to go a step further. They want to offer devices that are actually wearable, that are part of a patient’s clothing. This has been a considerable challenge. To ensure that the devices work effectively and provide ongoing service, the developers have had to solve two problems. First, they need to develop sensitive materials that can gather information continuously. Second, the power source has to be small enough to be wearable, and strong enough to be washable. Scientists have begun developing special fabrics that respond to body temperature and can gather information from the surface of the skin. Others have been working on batteries that are so small and flexible that they can be woven into cloth. These newest devices will not feel like technology; they will feel like a shirt or a sweater. 5  Monitoring health is just one of the purposes of this new smart apparel. Some will also deliver therapy to patients. This technology is like the patches that people use when they are trying to stop smoking. The clothing will continuously deliver small amounts of medicine through the skin. One day in the future, you may wear prescription jeans! 6  Wearable wireless health-care devices like these will allow many patients to live more independent lives. In the past, they may have had to stay in hospitals or see their doctors frequently. The devices will allow doctors to provide remote care, so patients can stay in their own homes even if they live alone. The information from the devices will inform doctors quickly if there is a problem, often before the patients themselves are aware that anything is amiss. 7  Although the motivation for the development of these devices comes primarily from concerns about patient care, industry experts say that the greatest potential for this market is not for people who are sick but for people who are well. 8  People in developed countries are increasingly concerned about staying in good health. They are careful about their diet, they exercise, and they try to control stress in their lives. Wireless apparel can help them manage all of these things. There are several devices already on the market—from bracelets to underwear—that can provide users with basic health information, such as body temperature, heart rate, and blood pressure. In addition, these devices can report how many steps a user takes, how many calories the user has burned, and even if the user is sitting up straight. For both the sick and the healthy, smart apparel may be in their future. Which sentence best describes the main idea for the whole reading?

What is one major challenge that smart apparel designers face? a. The power source must be part of the clothing. b. The technology is still too expensive. c. Many people are afraid to wear these devices.
