On a clear night you might see the Moon, some planets, and thousands of sparkling stars. You can see even more with a telescope. You might see stars where before you only saw dark space. You might see that many stars look larger than others. You might see that some stars that look white are really red or blue. With bigger and bigger telescope you can see more and more objects in the sky. And you can see those objects in more and more detail. But scientists believe there are some things in the sky that we will never see. We won't see them with the biggest telescope in the world, on the clearest night of the year. That's because they're invisible. They're the mysterious dead stars called black holes. You might find it hard to imagine that stars die. After all, our Sun is a star. Year after year we see it up in the sky, burning brightly, giving us heat and light. The Sun certainly doesn't seem to be getting old or weak. But stars do burn out and die after billions of years. As a star's gases burn, they give off light and heat. But when the gas runs out, the star stops burning and begins to die. As the star cools, the outer layers of the star pull in toward the center. The star squashes into a smaller and smaller ball. If the star was very small, the star ends up as a cold, dark ball called a black dwarf. If the star was very big, it keeps squashing inward until it's packed together tighter than anything in the universe. Imagine if the Earth were crushed until it was the size of a tiny marble . That's how tightly this dead star, a black hole, is packed. What pulls the star in towards its center with such power? It's the same force that pulls you down when you jump - the force called gravity. A black hole is so tightly packed that its gravity sucks in everything - even light. The light from a black hole can never come back to your eyes. That's why you see nothing but blackness. So the next time you stare up at the night sky, remember: there's more in the sky...

input: Please answer the following: Write a multi-choice question for the following article: Article: I love sleeping. It's something I'm good at. There's nothing better than nodding off on the sofa in front of the TV and when my head hits the pillow at night, I have no problem falling into a deep sleep within minutes. There is one place where I never nap and that's at work--but new research suggests I should! The idea of you and your colleagues heading off for a lie down in the afternoon may seem strange, but some companies such as Google and Facebook actually encourage it. Because it's thought that a power-nap makes them more refreshed and more focused, and this in turn makes them more productive. An Australian health writer called Victoria is a founder of a campaign called Nap Now which is trying to make sleeping at work more acceptable. She calls herself a " _ "! She says: "I think that our culture is a bit crazy not to accept it... It's time to end the common work principle which is all about working longer and harder." So should we all be taking a sleeping bag and pillow to work with us? A few years ago, research by the East of England Development Agency found 30% of people have their best ideas in bed compared to just 11% who have them at their desk. That suggests people are more creative when they are relaxed--and the agency has called for companies to put beds in the workplace. A nap in the afternoon is nothing new. In certain hot countries, such as Spain, a short rest or sleep in the afternoon-called a siesta-is perfectly normal. So maybe we should break from the traditional nine-to-five work culture and take up the siesta. The UK's Sleep Council claims the nine-to-five working day does not fit into the natural sleeping pattern of the human race and says that bosses need to introduce a more sleep-friendly working day.

input: Please answer the following: Write a multi-choice question for the following article: Article: It is pretty much a one-way street. While it may be common for university researchers to try their luck in the commercial world, there is very little traffic in the opposite direction. Pay has always been the biggest deterrent, as people with families often feel they cannot afford the drop in salary when moving to a university job. For some industrial scientists, however, the attractions of academia outweigh any financial considerations. Helen Lee took a 70% cut in salary when she moved from a senior post in Abbott Laboratories to a medical department at the University of Cambridge. Her main reason for returning to academia mid-career was to take advantage of the greater freedom to choose research questions. Some areas of inquiry have few prospects of a commercial return, and Lee's is one of them. The impact of a salary cut is probably less severe for a scientist in the early stages of a career. Guy Grant, now a research associate at the Unilever Centre for Molecular Informatics at the University of Cambridge, spent two years working for a pharmaceutical company before returning to university as a post-doctoral researcher. He took a 30% salary cut but felt it worthwhile for the greater intellectual opportunities. Higher up the ladder, where a pay cut is usually more significant, the demand for scientists with a wealth of experience in industry is forcing universities to make the transition to academia more attractive, according to Lee. Industrial scientists tend to receive training that academics do not, such as how to build a multidisciplinary team, manage budgets and negotiate contracts. They are also well placed to bring something extra to the teaching side of an academic role that will help students get a job when they graduate, says Lee, perhaps experience in manufacturing practice or product development. "Only a small number of undergraduates will continue in an academic career. So someone leaving university who already has the skills needed to work in an industrial lab has far more potential in the...
