input question: Write a multi-choice question for the following article, with the given choices and answer: Article: "Blogging is helping students to think and write more critically ,"says an Australian researcher, "and can help draw out people who would otherwise not engage in debate." These are the preliminary findings of PHD research by Anne Bartlett-Bragg, a lecturer at the University of Technology, Sydney, who has been using weblogs or blogs in her own teaching since 2001. "The students are thinking more critically." she says, "They are learning to be responsible and they're communicating outside the boundaries of the classroom and the institution, and they like that. "Bartlett-Bragg says in conventional teaching, students often rely on the lecturer as the main source of ideas and critique for their work. "I'm a bit over listening to my students giving me back in an essay what I've told them in class." she says. "I want them to think for themselves and get different perspectives." "What makes blogs useful is their interactive nature." she says. These web-based forums for discussing ideas, experiences or opinions allow students to discuss publicly what they are studying with other students and experts outside their own university. "I really encourage them to put their personal opinion in there, provided they are informed and backed up with evidence." Bartlett-Bragg says because a lot of academics in her field of electronic or e-learning now have their own blogs, students can engage directly with them. She says one of the most powerful facilities in weblogs is pinging, which involves a person positing a comment about someone else's work on their own blog. They use the "Trackback" tool to notify the author when they have published the comment, basically inviting them to discuss it. "They get such a buzz when they make a comment on another person outside the boundaries of the institution and that person responds, or even gives them some further reading." she says. "They are getting new perspectives that I can't give them in a normal lecture." Options: A think for themselves B have stronger sense of responsibility C know more about the world outside D finish an essay assignment easily Answer: A think for themselves Question:???
output answer: What Bartlett-Bragg likes most is that blogs can help students to _ .

Write a multi-choice question for the following article, with the given choices and answer: Article: Everyone knows that eating too much junk food is not good to our health. Yet, what is it about junk food that is so completely irresistible ? For one thing, it's everywhere. From chips in fast food restaurants to candy in supermarkets, junk food always seems available. Thankfully, science is now providing new clues to help us reduce snacking. Make friends with dainty eaters. Studies have found that people tend to increase or reduce the amount of food they eat depending on what their companions are taking in. See happy movies... and always get the smaller bag of popcorn . According to some experts, people eat up to 29% more popcorn if they are watching a sad or serious movie, compared to when they are watching a comedy. Viewers consumed almost 200 calories more when snacking from a large bucket, as opposed to when given a medium-sized container. Eat breakfast. Nutritionists have gone back and forth about the question of how much to eat in the morning, but new studies suggest that consuming a good breakfast is a must. Surveys on long-term weight-loss show that two key factors in keeping weight down are eating breakfast and exercising. Divide your food and conquer overeating. Any kind of dividing your food into portions slows down your eating. Any kind of marker makes you aware of what you're eating and of portion size. Researchers advise reallocating snack foods into small plastic bags. It sounds simplistic, but it works. Options: A how to make friends with dainty eaters. B how much to eat in the morning. C how to control overeating. D how to eat properly and healthily. Answer: D how to eat properly and healthily. Question:

Problem: Given the question: Write a multi-choice question for the following article, with the given choices and answer: Article: The world's earliest known fish hooks show that humans fished in the open sea for much longer than previously thought. Past studies have shown that early humans were able to cross the open ocean as far back as 50,000 years ago, but evidence that they could fish while in the open sea dated back only to 12,000 years ago. "In most areas of the world, evidence for our early ancestors' coastal exploitation was drowned by rising sea level," said researcher Sue O'Connor. Now O'Connor and her colleagues have found evidence of prehistoric fishing tools and the remains of large fish such as tuna at a cave shelter known as Jerimalai, located in the Southeast Asian island nation of East Timor. Their discovery uncovered fishing hooks made from bone that dated back to about 42,000 years ago. "It's possible that people caught the tuna in the deep channel that lies off the coast of the Jerimalai shelter," O'Connor said. The site, first uncovered in 2005, also included bone points, shell beads, the remains of fish, turtles, bats and birds, and nearly 10,000 stone tools. The island of Timor has very few land animals overall and only small birds call the island home, perhaps explaining why the ancient people here went fishing. About half the fish remains at the site came from fish such as tuna. Catching such fast-moving fish requires much planning and complex technology, suggesting that early humans developed these skills earlier than previously thought. Some other scientists might say that most of the fish bones seen are from young fish, and thus might have been caught more easily off the coast as opposed to in open waters. While this may be the case, it's still not easy to catch tuna -- it requires nets set in deep water. Options: A indicated tuna was a common dish for our early ancestors B showed the trend of sea movement C was difficult to find D was buried in cave shelters Answer: C was difficult to find Question:
