input question: Write a multi-choice question for the following article: Article: You stare at waterfall for a minute or two, and then shift your gaze to its surroundings. What you now see appears to drift upward. These optical illusions occur because the brain is constantly matching its model of reality to signals from the body's sensors and interpreting what must be happening--that your brain must have moved, not the other; that downward motions is now normal, so a change from it must now be perceived as upward motion. The sensors that make this magic are of two kinds. Each eye contains about 120 million rods , which provide somewhat blurry black and white vision. These are the windows of night vision; once adapted to the dark, they can detect a candle burning ten miles away. Color vision in each eye comes from six to seven million structures called cones . Under ideal conditions, every cone can "see" the entire rainbow spectrum of visible color1s, but one type of cone is most sensitive to red, another to green, a third to blue. Rods and cones send their messages pulsing an average 20 to 25 times per second along the optic nerve. We see an image for a fraction of a second longer than it actually appears. In movies, reels of still photographs are projected onto screens at 24 frames per second, tricking our eyes into seeing a continuous moving picture. Like apparent motion, color1 vision is also subject to unusual effects. When day gives way to night, twilight brings what the poet T.S. Eliot called "the violet hour." A light levels fall, the rods become progressively less responsive. Rods are most sensitive to the shorter wavelengths of blue and green, and they impart a strange vividness to the garden's blue flowers. However, look at a white shirt during the reddish light of sunset, and you'll still see it in its "true" color1--white, not red. Our eyes are constantly comparing an object against its surroundings. They therefore observe the effect of a shift in the color1 of illuminating on both, and adjust accordingly. The eyes can distinguish several million graduations of light and shade...???

Write a multi-choice question for the following article: Article: At 4:53 pm. on January 12, United Nations aid worker Jens Kristensen was at his desk reading documents on the third floor of the Christopher Hotel, which served as UN headquarters in PortauPrince, when he felt a tremor . Four seconds later, the earthquake hit. "In a split second, I considered whether to run for the door or hide under my desk," says Kristensen, 48. "The door was closed, and I thought that maybe it was too far and I would be caught under falling debris , so I hid under the table." A bookshelf topped onto his desk, protecting him from being crushed by rubble and trapping him in a tiny pocket. "I was confined as if in a small coffin," he says. It was so dark, and it didn't matter if his eyes were open or closed. He used the light from his mobile phone to see around him. He found, among other items, a jar of instant coffee. "I had no food or water, only the coffee to suck on if I needed it." At about 6:30 am. on January 17, an oil leak silenced the building's generators, and Kristensen was able to hear muffled voices above where he was buried. "I thought, I was too tired to bang and shout. But then I realized, I had to take every chance. This could be one." So he called out. Six hours later, Kristensen saw his rescuers' faces. "It was so amazing. I felt I had received a second birthday," he recalls. Dehydration and pains but with only a bruise and a scratch, Kristensen took three days to recover. The UN lost more than 90 people in Haiti. But Kristensen says that the outpouring of love helps heal the pain: "The genuine happiness of people toward me here has been wonderful. You feel part of a larger family."

Problem: Given the question: Write a multi-choice question for the following article: Article: It can be as simple or as complex as you want. Anybody who enjoys the cinema knows that when the final credits roll they include everyone who has contributed -- Director, Performers, Best Boy, Make Up, etc. It usually takes over a hundred people working a year to make a feature film, ten people to produce a pop promo and around twenty to film a documentary. The reason so many people are involved is because films need to be made quickly and on budget. Many famous directors started by making films completely on their own -- Orson Welles, George Lucas, Robert Rodrigues. You may not have the special effects and big budgets of Hollywood but you do have time on your side. Use it to experiment and make a few mistakes. It's the way to learn. And that's where the fun begins. Go on; make a film. Now, let's talk about how to prepare for the shoot . If you're making the film with other people, organize your cast and crew effectively. Make sure everybody knows their role and what day and time they're needed. Give people specific jobs so they can become experts in their field. For example, a sound recordist listens to the sound through headphones as it's being recorded, and holds an extra microphone if needed. A camera operator frames the picture, sets focus, checks the light and records the action. The editor "cuts" the picture together after it's shot. A producer is the contact point for the film. He or she makes sure crew and cast are there on time, talks to the press and organizes the budget. A director has to make sure their vision is communicated. To do this everyone needs to be clear about what the director expects from each scene and each shot. You may also need a make-up-artist, a choreographer, a driver, etc. However, you can quite easily make your first film on your own. Make a schedule that says which shots are to be taken where and when (this is called a shooting schedule) and when you've completed a take, cross it off the list. Remember that you may want to shoot "out of sequence", e.g. shoot the last...
