input question: Write a multi-choice question for the following article, with the given choices and answer: Article: Do's and Don'ts in Whale Watching The Department of Fisheries and Oceans has developed guidelines for whale watching in Johnstone Strait,where killer whales are found on a daily basis each summer. It is strongly recommended that vessel operators follow these guidelines for all kinds of whales. * Approach whales from the side, not from the front or the back. * Approach no closer than 100 metres, then stop the boat but keep the engine on. * Keep noise levels down-no horns, whistles or racing of engines. * Start your boat only after the whales are more than 100 metres from your vessel. * Leave the area slowly, gradually moving faster when you are more than 300 metres from the whales. * Approach and leave slowly, avoiding sudden changes in speed or direction. * Avoid disturbing groups of resting whales. * Keep at low speeds and remain in the same direction if travelling side by side with whales. * When whales are travelling close to shore, avoid crowding them near the shore or coming between the whales and the shore. * Limit the time spent with any group of whales to less than 30 minutes at a time when within 100 to 200 metres of whales. * If there is more than one vessel at the same observation spot, be sure to avoid any boat position that would result in surrounding the whales. * Work together by communicating with other vessels, and make sure that all operators are aware of the whale watching guidelines.

Write a multi-choice question for the following article, with the given choices and answer: Article: In many ways, the earliest periods of photography are the most satisfying. Learning to use the controls is easy and comes quickly, and you can measure the results in terms of sharp and correctly developed pictures. Once you have mastered that, you can start on the second step of your photographic work. Using these basic skills in a wide variety of situations to give the pictures you want, noticing what you see through the viewfinder and turning that into the most effective picture becomes totally interesting. All good photographs have one thing in common; there is no doubt what the subject of the picture is meant to be. Every photographer must use those same standards to his or her work, not only to the finished results but to the subject before he or she takes it. Always work out quite clearly what the subject of the picture is to be and why you are taking the picture. For example,"I am going to take a picture of this street to show the different styles and ages of the buildings and that people have been living, working and shopping in them since time began."By doing this you have a better idea of what to include in the picture and what to leave out. How often have you been shown photographs taken by people away on a trip somewhere? The judgment is always similar, something about"the car park is out of the picture to the left", or"you can't quite see from this picture but if you go up the street". The photographs are usually collections of buildings, people, parked cars, possibly a distant look of an ancient church, and best of all, a figure which you are told is Aunt Henrietta, disappearing in the middle distance. When photographers show you their pictures, they have a clear idea of what they want to bring to your attention, but it often does not appear in the picture. If they had given just a little of their time to think about their future judgment before taking the picture, then the picture would relate its own story. Good pictures can show their subjects quickly and easily. Options: A their pictures include the buildings and people B the details are not clear in their pictures C the subjects of their pictures are not obvious D the explanation given for their pictures is mistaken Answer: C the subjects of their pictures are not obvious Question:
----
Answer: Many photographers fail because _ .

Problem: Given the question: Write a multi-choice question for the following article, with the given choices and answer: Article: Nuclear-powered aircraft carriers are considered one of the most important marine weapons in the 20th century. So far, only two countries in the world--the prefix = st1 /USAandFrance--have ever produced them. But these frightful fighting machines are about to enter Asia. The US Navy said last month that one of its nine nuclear-powered aircraft carriers will be sent to Japanto replace the diesel-powered carrier Kitty Hawk in 2009 in an agreement on October 30th. The two countries also planned to level up their military cooperation and theUSAcalled forJapanto take a large role in alliance military moves. It will be the first time that a nuclear-powered carrier is based in Japan. Bombed byUSforces in World War II at Hiroshima and Nagasaki,Japanis the only world country to have been attacked by a nuclear weapon. Therefore, the citizens are highly sensitive to where nuclear-powered weapons are based. "A radiation leak at Yokosuka would kill 100,000 people as far away as Tokyo, and could cause billions of dollars in damage," said Masahiko Go to, leader of a protest group inYokosuka. His group has collected more than 300,000 signatures of people acrossJapanopposed to the nuclear carrier. The 44-year-old Kitty Hawk, the USnavy's oldest active ship, has been based in Yokosuda since 1998. The new carrier, yet to be _ , will travel faster, be capable of supporting longer operations and carry with it the Navy's most modern technology. Experts pointed that this change is not only to strengthen the US-Japan military alliance but also to keep the military power of ChinaandNorth Koreawithin limits. However, Japanese experts don't believe that the countries are threats to the region. "There is no need for Japanto have a nuclear carrier as defense," said Tetsuo Maeda, an international relations professor atTokyoInternationalUniversity. He said that the change of ship indicates an increased military capacity, in the region, much more than what is needed. Options: A No country in the world has been attacked by a nuclear weapon except Japan. B A radiation leak happened to the nuclear-powered aircraft carrier at Hiroshima. C ChinaandNorth Koreaare threats to the region. D Kitty Hawk is the name of the old nuclear-powered aircraft carrier.
