Problem: Write a multi-choice question for the following article: Article: Most students try to learn English grammar using grammar textbooks. They study grammar rules and take grammar tests. They use an analytical approach, attempting to memorize, and then apply, a great number of rules. However, research has proved this method inefficient and ineffective. The truth is, the human brain simply cannot consciously remember process and use hundreds of or thousands of grammar rules. Real speech is too fast. Native speakers do not learn grammar in this way, but rather intuitively and unconsciously. They learn in a complete way, not by attempting to memorize individual grammar rules. As a result, native speakers use correct grammar fluently and easily. Fortunately, it is possible for English learners to learn grammar this way. Language teacher Blaine Ray has developed a unique "intuitive" approach to teach English grammar. Her system uses "point of view" stories to teach the patterns of English grammar, allowing students unconsciously to acquire correct grammar without ever studying grammar rules. In this system, the teacher first tells a simple story from one point of view. It may be told about the past, then repeated, but beginning with "since he was a child"; then repeated again, but this time about the future. Listening to these stories allows students intuitively and effortlessly to learn English grammar and makes them be able to use it correctly when they speak. Point of View Stories is a creative new way to study English grammar, and offers hope to millions of frustrated English learners.

A: Question: Why shouldn't the English learners use an analytical approach?Options:A because the analytical approach can let them learn English grammar effortlesslyB because the analytical approach makes them be able to use English correctly when they speak.C because the analytical approach can't let them memorize and then apply a great number of rules.D because Real speech is too fast.Answer:D

Problem: Given the question: Write a multi-choice question for the following article: Article: If you know the following fact, you'll understand why many people suffer from foot problems. The average person walks the equivalent of three times around the Earth in a lifetime. That is enormous wear and tear on the 26 bones, 33 joints and more than 100 muscles that make up the foot. In a recent survey for the American Podiatric Medical Association, 53 percent of respondents reported foot pain so severe that it affected their daily function. On average, people develop pain in their 60s, but it can start as early as the 20s and 30s. And usually women give care to their feet while men don't. "A lot of people think foot pain is part of the aging process and accept it, and walk with pain," said Dr Andrew Shapiro. Though some foot problems are inevitable, their progress can be slowed. The following questions will help you assess whether you should take more preventive action as you age. Do you have flat feet or high arches ? Either puts feet at risk. Shoes that support the arch and heel can help flat feet. People with high arches should look for roomy shoes and softer padding to absorb the shock. Proper exercises also strengthen muscles, supporting the foot. Do your shoes fit? In the survey, more than 34 percent of men said they could not remember the last time their feet were measured. 20 percent of women said that once a week they wore shoes that hurt, and 8 percent wore painful shoes daily. Feet flatten and lengthen with age, so if you still stick to the shoe size you wore at the age of 21, get your feet measured. Do you walk? Putting more mileage on your feet is the best way to exercise the muscles and keep them healthy.

input question: Write a multi-choice question for the following article: Article: Tips for Getting the Most out of a "Photo walk" Photo walks are a great way to get out and get clicking, either by yourself, with a couple of friends, or with a group of people. They can be wonderful for seeing a neighborhood or wild space with new eyes, getting inspired to be more creative with angles and subjects, as well as simply spending time with fun people. Here are a few tips for making sure you get the most out of a photo walk. Pick a spot with lots of interest A photo walk is a perfect excuse to go exploring a new area. However, if you've never been to the scene before, you might be disappointed at the final photos. Base your chosen spot on what you feel like photographing---whether that is buildings, people, busy streets, a festival, nature and so on, and make sure the place you're heading for is filled with what you most want to shoot. It will pay off in a satisfying walk if you research your chosen spot beforehand and know what to expect. Invite anyone, no matter what their skill level is You'll be surprised at what you learn from people who seem to know nothing about photography. Even with a simple camera, they can catch some outstanding photos. So bring Aunt Betty or your 10-year-old nephew or anyone else whose company you might enjoy on a walk and keep an open mind. Don't forget them Be sure to take the important small things, such as an extra memory card (or two), an extra fully charged battery, comfortable shoes and clothing. And remember a notepad and pen for taking down notes about places, times, conditions, the names and information of people you meet and any other information you might want to remember about certain shots. Keep an eye out for danger Apart from watching the sky for rain, you'll want to watch out for other people as well. Smartphones are always a target for thieves but they have become much clearer about the value of digital cameras. Don't make yourself a target by standing for a very long time holding your camera out in front of you. If you're in an area that is really...???
output answer: Question: You are supposed to hold the camera around your wrist or shoulder in case _ .Options:A it is stolen by a thiefB it gets wet in the rainC it loses some informationD it falls down on the groundAnswer:A

[Q]: Write a multi-choice question for the following article: Article: Medical drugs sometimes cause more damage than they cure. One solution to this problem is to put the drugs inside a capsule, protecting them from the body--and the body from them--until they can be released at just the right spot. There are lots of ways to trigger this release, including changing temperature, acidity, and so on. But triggers can come with their own risks--burns, for example. Now, researchers in California have designed what could be a harmless trigger to date: shining near-infrared light (NIR, ) on the drug in the capsule. The idea of using light to liberate the drug in the capsule isn't new. Researchers around the globe have developed polymers and other materials that begin to break down when they absorb either ultraviolet (UV, ) or visible light. But tissues also readily absorb UV and visible light, which means the drug release can be triggered only near the skin, where the light can reach the capsule. NIR light largely passes through tissues, so researchers have tried to use it as a trigger. But few compounds absorb NIR well and go through chemical changes. That changed last year when Adah Almutairi, a chemist at the University of California, San Diego, reported that she and her colleagues had designed a polymer that breaks down when it absorbs NIR light. Their polymer used a commercially available NIR-absorbing group called o-nitrobenzyl (ONB). When they catch the light, ONB groups fall off the polymer, leading to its breakdown. But ONB is only a so-so NIR absorber, and it could be poisonous to cells when it separates from the polymer. So Almutairi and her colleagues reported creating a new material for capsules that's even better.This one consists of a long chain of compounds called cresol groups linked in a polymer. Cresol contains reactive components that make it highly unstable in its polymeric form, a feature Almutairi and her colleagues use to their advantage. After polymerizing the cresols, they cap each reactive component with a light-absorbing compound called Bhc. When the...
