Problem: Write a multi-choice question for the following article, with the given choices and answer: 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. Options: A because the analytical approach can let them learn English grammar effortlessly B 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 because Real speech is too fast. Question:

A: Why shouldn't the English learners use an analytical approach?

Problem: Given the question: Write a multi-choice question for the following article, with the given choices and answer: Article: The people who built Stonehenge in Southern England thousands of years ago had wild parties, eating barbecued pigs and breaking pottery. This is according to recent work by archaeologists--history experts who investigate how human beings lived in the past. Archaeologists digging near Stonehenge last year discovered the remains of a large prehistoric village where they think the builders of the mysterious stone circle used to live. The village is about 4,600 years old, the same age as Stonehenge and as old as the Pyramids in Egypt. It is less than two miles from the famous ancient landmark and lies inside a massive man-made circular dirt wall, or "henge", known as the Durrington Walls. Remains found at the site included jewellry, stone arrowheads, tools made of deer antlers, wooden spears and huge amounts of animal bones and broken pottery. "These finds suggest Stone Age people went to the village at special times of the year to feast and party", says Mike Parker-Pearson from Sheffield University in England. He said many of the pig bones they found had been thrown away half-eaten. He also said the partygoers appeared to have shot some of the farm pigs with arrows, possibly as a kind of sport before barbecuing them. An ancient road which led from the village to the River Avon was also found. Here, the experts think, people came after their parties to throw dead s in the water so the bodies would be washed downstream to Stonehenge. Parker-Pearson believes Stonehenge was like a cemetery where ancient Britons buried the dead and remembered their ancestors. The theory is that Stonehenge is a kind of spirit home to the ancestors. The recent discovery of the village within the Durrington Walls shows that Stonehenge didn't stand alone but was part of a much bigger religious site, according to Parker-Pearson.People still come to worship and celebrate at Stonehenge today. They meet there when the sun sets on the shortest day of winter and when it rises on the longest day of summer. But the days of barbecuing whole pigs... Options: A A village where hundreds of people once lived. B A place that regularly hosted large parties. C A church where local villagers would get married. D A site where dead people were placed or remembered. Answer: D A site where dead people were placed or remembered. Question:

What was Stonehenge according to the text?

[Q]: Write a multi-choice question for the following article, with the given choices and answer: 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... Options: A protected B formed C exposed D combined Answer: C exposed Question:
