Please answer this: Write a multi-choice question for the following article: Article: The world's oceans are slowly getting more acidic, say scientists. The researchers from California say the change is taking place in response to higher levels of carbon dioxide in the atmosphere. The lowering of the waters' pH value is not great at the moment but could pose a serious threat to current marine life if it continues, they warn. Ken Caldeira and Michael Wickett, from the Lawrence Livermore National Laboratory, report their concerns in the journal Nature. Increasing use of fossil fuels means more carbon dioxide is going into the air, and most of it will eventually be absorbed by seawater. Once in the water, it reacts to form carbonic acid. Scientists believe that the oceans have already become slightly more acidic over the last century. But these researchers have tried to predict what will happen in the future by combining what we know about the history of the oceans with computer models of climate change. "This level of acidity will get much more extreme in the future if we continue releasing CO2 into the atmosphere," said Dr Caldeira. "And we predict amounts of future acidity will exceed anything we have seen over the last several hundred million years, let alone perhaps after rare catastrophic events such as asteroid impacts ." If carbon dioxide release continues unabated , ocean pH could be reduced by as much as 0.77 units, the authors warn. It is not ly clear what that means for marine life, however. Most organisms live near the surface, where the greatest pH change would be expected to occur, but deep-ocean lifeforms may be more sensitive to pH changes. Coral reefs and other organisms whose skeletons or shells contain calcium carbonate may be particularly affected, the team speculate. They could find it much more difficult to build these structures in water with a lower pH. In recent years some people have suggested deliberately storing carbon dioxide from power stations in the deep ocean as a way of curbing global warming. But Dr Caldeira said that such a strategy should now be...

Problem: Write a multi-choice question for the following article: Article: Airport Information Name:Copenhagen Airport Location: Located 8km southeast of Copenhagen(capital of Denmark) No. of terminals:4 Disabled facilities: Copenhagen Airport is physically accessible throughout. Wheelchair-accessible toilets and reserved seating are provided and dedicated parking spaces are available. Passengers with disabilities are requesited to inform their airline in avdance about their needs. *Car Parking: There are more than 10,000 car parking spaces in short-, medium- and long-term car parks at Copenhagen Airport. The P6, P7, and P8 areas offer short-term options directly linked terminals 2 and 3. Medium-term rates are avaiable in P1, P2, P5, P8, P10 and P12, which are all ly near the terminal buildings. Economy long-term parking is available at P15 and P17, a little further from the terminals (free tasnsit buses sre provided). The airport parking office is located between Terminals 2 and 3 and is open 24 hours. *Public Transport Rail; There are direct high-speed trains to Copenhagen Central station(journey time: 14 minutes; fare; Kr36), as well as a number of other destination in Denmark and Sweden. The station and ticket office are situated in Terminal 3. Metro: The Metro M2 line connects to the city center (journey time: 14 minutes;fare: Kr24). The station is situated in Terminal 3, from which tickets can be purchased. Bus: Several buses(5A, 35 and 36)run from Copenhagen Airport to the city center(journey time: about 55 minutes; fare:Kr 30)and beyond. Taxi: Taxis are readily available from ranks outside the arrival areas of Terminal 1, 2 and 3. The ride into Copenhagen takes about 15 to 20 minutes, and prices start from Kr250.

A: Question: Which is the fastest and cheapest way to the city center?Options:A By MetroB By railC By busD By taxiAnswer:A

Q: Write a multi-choice question for the following article: Article: Boom boom!( I'm here, come to me!) Krak krak!( Watch out, aleopard !) Hok hok hok!( Hey, crowned eagle!) Very good -- you've already mastered half the basic vocabulary of the Campbell's monkey, which lives in the forests of the Tai National Park in Ivory Coast. The adult males have six types of call, each with a specific meaning, but they can mix two or more calls together into a message with a different meaning. Having spent months recording the monkeys' calls in response to both natural and artificialstimuli , a group led by Klaus Zuberbuhler of the University of St. Andrews in Scotland argues that the Campbell's monkeys have a certain form ofsyntax . This is likely to be controversial because despite great effort to teachchimpanzees language, they showed little or no ability to combine the sounds they learned into a sentence with a larger meaning. Syntax, basic to the structure of language, uniquely belongs to humans. "Krak" is a call that warns of leopards in the neighborhood. The monkeys give it in response to real leopards and to leopard shouting broadcast by the researchers. The monkeys can vary the call by adding "-oo": "Krak-oo" seems to be a general word for hunter, but one given in a special context - when monkeys hear but don't see a hunter, or when they hear the alarm calls of another species. The "boom-boom" call invites other monkeys to come toward the male making the sound. Two booms can be combined with a series of "krak-oos", with a meaning entirely different to that of either of its single parts. "Boom boom krak-oo krak-oo krak-oo" is the monkey's version of "Timber!" - it warns of falling trees. If Zuberbuhler is correct, the Campbell's monkeys can both vary the meaning of specific calls by adding something and combine calls to make a different meaning.
