Problem: Given the question: Write a multi-choice question for the following article, with the given choices and answer: Article: Question: What is more astonishing than a 60-ton whale on a flatbed truck being driven down the street? Answer: A 60-ton whale on a flatbed truck exploding and raining blubber ( fat of whales) all over the sidewalk. That's what happened in Taiwan recently, when a dead sperm whale being shipped to the Halobios Research Center for an autopsy developed an extremely bad case of gas and blew up before it reached its destination. The whale was found alive on a prefix = st1 /Taiwanbeach last weekend, and died shortly after it was discovered. Since the 56-foot whale was the largest whale ever beached onTaiwan's shores, scientists wanted to study it and perform an autopsy for educational purpose. Obviously, too much time passed between when the animal died and the time it was set to be moved to the autopsy location, because it had already started to go bad. When things rot, they give off gases as a by-product. In the whale's case, the gases were trapped in its belly. The pressure inside the rotting creature grew so much that it popped like an over-filled balloon. Unfortunately, it was on a truck in the middle of the city of Taiwanat the time--- cars and shops lining the street were covered with whale bits and juices, much to their owners' discouragement. According to the news reports, traffic was tied up for hours while officials tried to clean up the streets. Newspaper editors worldwide were probably smiling to themselves, since they had a ready-made headline--- several reports about the incident were titled " There She Blows!" after the famous line from the book Moby Dick. Options: A explain the reason B sell newspapers C attract readers D give an immediate answer Answer: C attract readers Question:

input question: Write a multi-choice question for the following article, with the given choices and answer: Article: Many people say they can not start their day without first having a cup of coffee or tea.People say these drinks help them think clearly and feel more awake.This is because of caffeine,a kind of matter found in some plants.Caffeine helps to give a jumpstart to the nervous system.Now a new report says it may also improve long-term memory. Michael Yassa is a neurobiology professor at the University of California.He and other researchers wanted to know if caffeine could improve what they called memory consolidation.They asked a group of individuals to learn something new,then the same people were given caffeine,the active component in coffee,tea and chocolate. He and the other researchers worked with a group of l60 people who were Caffeinefree.On the first day,all the subjects were shown pictures of everyday objects.They were asked to identify whether the pictures could be found inside the house or outdoors.Some of the subjects were then given a caffeine pill,the others were given a placebo--a pill containing an inactive thing.On the second day,all of the subjects were asked to look at more pictures.Some of the images were exactly like the ones they had seen 24 hours early.But other images were different.And a third group of pictures was similar to the first group but a little different.The participants had to decide whether the images they saw were the same or different from the ones on the first day. Professor Yassa says their answers help to show the effects of caffeine on memory.He says those who took the caffeine pills had a ten to twelve percent increase in their ability to remember the objects.The amount of caffeine the researchers used in the study was similar to one strong cup of coffee. Professor Yassa says pills with a little more caffene also increased memory,but resulted in some participants appearing more nervous. Options: A forbid people to drink coffee B report a new research of coffee C attract readers to drink coffee D introduce the procedure of research Answer: B report a new research of coffee Question:???

Please answer this: Write a multi-choice question for the following article, with the given choices and answer: Article: The Royal Commission on Environmental Pollution has just published a report on new materials and has looked at the case of nanotechnology , which describes the science of the very small. Nanotechnology covers those man-made materials or objects that are about a thousand times smaller than the microtechnology we use, such as the silicon chips of computers. Nanotechnology gets its name from the nanometer, which is a billionth of a meter. There are about 600 consumer products already on the market that use nanotechnology. Nanomedicine is also being developed to fight cancer and other fatal diseases. The Royal Commission found no evidence of harm to health or the environment from nanomaterials, but this "absence of evidence" is not being taken as "evidence of absence". In other words, just because there are no apparent problems, this is not to say that here is no risk now or in the future. The commission is concerned about the pace at which we are inventing and adopting new nanomaterials, which could result in future problems that we are ill-equipped to understand or even find with current testing methods. One of the problems about nanotechnology is that when we make something very small out of a well known material, we may actually change the functionality of that material even if the chemical composition remains the same. Indeed, it is not the particle size that should concern us, but its functionality. Take gold, for example, which is a famously inert substance, and valuable because of it. It doesn't rust or corrode because it doesn't interact with water or oxygen. However, a particle of gold that is between 2 and 5 nanometers in diameter becomes highly reactive. This is not due to a change in chemical composition, but because of a change in the physical size of the gold particles. How can a change in size result in a change of function? One reason is to do with surface area. Nanoparticles have relatively a much bigger surface area. It is like comparing the surface area of a basketball with the total surface... Options: A expand surface area -increase interactivity - change functionality-cause possible dangers B expand surface area - change functionality - increase interactivity -cause possible dangers C increase interactivity - expand surface area - change functionality-cause possible dangers D increase interactivity - change functionality - expand surface area-cause possible dangers Answer: A expand surface area -increase interactivity - change functionality-cause possible dangers Question:
