question:
Article: Although Thomas Edison created the technologies behind three major 21st century industries electrical power,recorded music and movies--his greatest invention may have been the modern method of inventing.He basically came up with the modern system of research and development.Edison was not the only scientist doing research in his garage but someone who gathered around him a team of creative scientific minds.Edison's 1aboratories were the forerunners of Apple,Google and Microsoft. Yet for a11 his scientific gifts,he was no Steve Jobs or Bill Gates.He once said,"Anything that won' t sell,I don' t want to invent." But Edison,unlike Jobs or Gates,had no real sense of what the public wanted or how to change his discoveries into products that might sell.It took him years to understand that the phonograph was not a business tool but an entertainment invention.He helped create movies but resisted the idea that people might want to go into a theater to watch one. We chose Edison this year because we need his example now more than ever.Though we live in a time of great reformation,the U.S.is in danger of losing its advantage in science and technology.American investment in research and development has not increased as a percentage of GDP since the mid1980s,while the government' s share has been dropping.And this is at a time when China is rapidly increasing its money on research and development.The U.S.was once among the 1eading nations.Now it ranks near the bottom of the 23 nations that collect such data.We hope that Edison' s story might not only encourage reformation but also inspire more young Americans to study science and engineering.
Answer: Edison wanted to invent things that sold well.

Article: Almost all of us have been there: A sense of uneasiness strikes us when we see the battery running low on the smartphone. While today's smartphones enable us to surf the Internet, take pictures and play music, their limited, sometimes annoyingly short battery life has started to make people full of memories of early models. "My favorite phone of all time was a silver Nokia 6310i from the early 2000s. It may be primitive by today's standards, but it could run for 17 days on a single charge," wrote Daily Mail columnist David Derbyshire. But scientists spend no time thinking about the past. They have built an aluminium battery which could be a cheap, fast-charging alternative to current designs. You can squeeze, and practically bend it in half without breaking the packet. It is more environmentally friendly than alkaline batteries, and more safe than lithium batteries - it won't catch fire "even if you drill through it", as Hongjie Dai of Stanford University told The Telegraph. The battery is the work of a team led by Dai. And the best part is that it has a recharge time of around one minute. However, at present, the only problem is that it produces just half the voltage of a typical lithium battery. But Dai explained they were setting about changing the voltage and energy density ". "Our battery has everything else you'd dream that a battery should have. I see this as a new battery in its early days," he told The Telegraph.
Answer: 5
answer:
How many advantages does the aluminium battery have according to the article?

Article: MERS, also known as Middle East Respiratory Syndrome, has made its way to the US. The second patient was in Orlando, Florida while the first reported case was in Indiana. Tom Frieden, director of the Centers for Disease Control and Prevention, said the disease has mainly been transmitted by close personal contact, such as directly caring for a very ill person. The virus is formally called MERS-CoV because it's part of the corona virus family that includes the common cold and severe SARS. SARS was ly easy to stop a decade ago, because it was being transmitted by caged animals in Chinese markets. MERS-CoV was first identified in people in 2012, but has been spreading rapidly since March, 2015. The vast majority of those cases occurred in Saudi Arabia. The patient in Orlando felt ill on the first flight but not ill enough to notify a doctor. Early on May 9, he apparently became concerned that he was still feeling ill, and he went to the emergency room at Dr. P. Phillips Hospital. He identified himself as recently having been in Saudi Arabia, so he was quickly isolated to avoid infecting other patients. Wayne Marasco, an expert at the Dana-Farber Cancer Institute and Harvard Medical School, said his biggest concern about MERS-CoV is how little we know about it. It's still not clear, in some instances, where the virus comes from, how it is transmitted or who is most subject.
Answer: By close personal contact.
answer:
According to Tom Frieden, how is a person mainly infected by MERS?
