Example Input: 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
Example Output: How many advantages does the aluminium battery have according to the article?

Example Input: Article: The term culture now is more used to describe everything from the fine arts to the outlook of a business group or a sports team. In its original sense, however, culture includes all identifying aspects of a racial group, nation, or empire: its physical environment, history, and traditions, its social rules and economic structure, and its religious beliefs and arts. The central beliefs and customs of a group are handed down from one generation to another. It is for this reason that most people regard culture as learned rather than innate. People acquire a culture because they are not born with one. The process by which a person develops a taste for regional foods, accented speech, or an outlook on the world over time, therefore, is known as enculturation . Cultures are often identified by their symbols -- images that are familiar and coated with meaning. Totem poles carved with animals and creative figures suggest aspects of the Native American peoples of the Pacific Northwest but more literally represent specific tribes. In Asia and India, the color1 of yellow is connected with temples while in ancient China it was a color1 only the emperor's family was allowed to wear. Thus, different cultures may respond to a symbol quite differently. For example, to some a flag may represent pride, historical accomplishments, or ideals; to others, however, it can mean danger or oppression. To individuals unfamiliar with cultures outside their own, the beliefs, behaviors, and artistic expression of other groups can seem strange and even threatening. A society that ranks all other cultures against its own standards is considered to be ethnocentric (from the Greek ethnos, meaning "people," and kentros, meaning "center"). A strongly ethnocentric society assumes also that what is different from its own culture is likely to be inferior and, possibly, wrong or evil. All people are ethnocentric to some degree, and some aspects of ethnocentrism, such as national pride, contribute to a well-functioning society. An appreciation for one's own culture, however, does not prevent acceptance and respect for another culture. History documents the long-term vigor and success of multicultural groups in which people from numerous and various cultural backgrounds live and work together. Extreme ethnocentrism, in contrast, can lead to racism -- the belief that it is race and racial origin that account for variations in human character or ability and that one's own race is superior to all others.
Answer: Culture, a distinctive identity of a nation
Example Output: Which might be the best title of the passage?
