Question: 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?

Question: Article: Mr. Sankaram, a physics teacher, was known for his antics in his classroom to make the dull lessons in physics lively and interesting. Mixing different chemical drugs in the lab to become new substances in chemistry makes students excited. While studying botany or zoology, students can visit a garden or zoo. But physics limits students to listening to the boring lectures which are hard to understand. For example, why an apple dropping from a tree travels downwards but not upwards. But Mr. Sankaram's classroom antics to cause students to listen to topics such as how sound travels in air or why light travels faster than sound made him stand out from the rest of the teachers. At that time, most students in our school attended the college to please their parents, and some parents were proud of their children for simply attending a college, no-matter whether they benefited or not. They didn't study hard. But a few students were diligent and they wanted to study pre-medical courses to gain admission into the medical school. The schooling of pre-medical courses was very expensive. The college was next to the medical school. The wall separating them was about four feet high. Few tried to jump over the wall to get free pre-medical courses. Doing this was at risk of injuries and the climbing was forbidden. The college where Mr. Sankaram taught was known for unruly and naughty students. The unruly students usually sat at the back of the classroom. When a student from the back of the classroom tried to disrupt the class, Mr. Sankaram would say, "Dare you go ahead to make noise? Can you jump over the four-foot wall to get into the medical school?" The student's face went red and he became silent. In the physics class . I sat in the first row to escape from the troublemakers at the back. One day during the class. Mr. Sankaram unexpectedly asked me, "Can you jump over the four-foot wall?" I shook my head and answered, "No, sir, I couldn't jump over a one-foot wall, let alone a four-foot wall." Mr. Sankaram wasn't satisfied with my reply but waved his hand for me to sit down. He looked at me in the eyes hard and said, "If you can. Believe in yourself!" There were stories about Mr. Sankaram's past history. As a student at same college years ago, he went into much depression for some time when he couldn't get into the medical school. In fact he could have been admitted by the school by his ability of studying. Because his family couldn't afford his pre-medical courses and he didn't dare to climb the wall, he often walked back and forth along the four-foot wall talking to himself and sometimes cried over his failure. Whether this story was true or false it was passed on from year to year. So Mr. Sankaram had a nickname "four-foot." It was true that he left his dream to his students and he began challenging the students' ability to jump over the four-foot wall to get into the medical school. As a student I failed at my attempt to get admission into the medical school. In fact not all students wanted to be a doctor. And years later I ended up as a chemistry teacher at the same college. I thank Mr. Sankaram for his encouragement to me, and I am determined to follow his example to make my class interesting. Mr. Sankaram passed away years ago. He will always be remembered for his wonderful teaching techniques such as dancing movements and his encouraging words.

Question: Article: Long long ago, there was an old merchant who had three sons. "To which one shall I leave my fortune?" he wondered. "It must be to the cleverest son. But which one is the cleverest?" He called his three sons to him. "Here is some money," he told them, "you must each take one coin to buy something that will fill this room. Anyone who can do this shall have my fortune." "It is a big room," said the eldest son. "One coin will not buy very much," said the second son. But the youngest son said nothing. He stood and thought, and then he smiled, "Come, brothers," he said, "let us go to the market." The eldest son bought straw with his coin. But one coin bought only a bit of straw. Even when he had spread it as much as he could, the straw covered only a corner of the room. The second son bought sand with his coin. But one coin bought only a bit of sand. Even when he had spread it as much as he could, the sand covered only half of the floor. "What did you buy?" the eldest son angrily asked the youngest son. "You don't have any straw." "Yes, what did you buy?" the second son asked angrily. "You don't have any sand." "I bought this," said the youngest son. "A candle!" cried his brothers. "What good is a candle?" "Watch", said the youngest son. He lit the candle, and all at once the room was filled from wall to wall, from ceiling to floor. It was filled with light! "Although you are the youngest, you are indeed the cleverest of my sons," the old merchant said. And that is how, the old merchant left his fortune to his youngest son, the one who could fill a room with light.
