input: Please answer the following: Write a multi-choice question for the following article, with the given choices and answer: Article: Native to America, the cane toad was introduced to northern Queensland 70 years ago to control sugarcane beetles . The toads failed in that duty but spread across prefix = st1 /Queenslandand into neighboring northern area. Now it calmly invades the states of Western Australia and New South Wales (NSW). NSW wildlife experts fear _ --which have poisonous backs that kill hungry predators, --will have a terrible effect on native animals. Those fears may be about to be realized. Australia's leading government research body, the Commonwealth Science and Industry Research organization (CSIRO), forecasts a rise in average temperatures that will make NSW ideal living place for the cane toad. Tony Robinson, head of CSIRO's Wildlife,Pests,and Diseases Program, said climate change is increasing the amount of suitable living place for the toad. "With climate change, the cane toads might go down as far as Sydney and some areas of Western Australia," Robinson said. Recent estimates put the pace of the toad's westward march at nearly 17 miles(27 kilometers)a year and slightly slower from north to south. More southerly cities, such as Melbourne and Adelaide, would likely remain too cold and dry to ever suit the toads, Robinson noted, but Perthcould expect cane toads in five years' time. Sydney could see their arrival in the next 20 years. Robinson said there is no 0ne method that will keep the toads under control. The cane toads already cover at least half of Queenslandand most of the northern country the toads are believed to number in the billions. A Venezuelan virus was tried in the 1990s but had to be given up after it was found to also kill native frog species. Scientists and governmental bodies believe a national approach is needed. The main threat the toads cause to species such as dingos, quolls, goannas, and crocodiles is the poison contained in glands on each of the frogs' shoulders. The poison sprays out when the toads are threatened or handled roughly. The poison is made up of 14 different chemicals.... Options: A The cane toads are strong enough to kill dingos, quolls or even crocodiles. B With 14 different kinds of poisons in its body, a cane toad always wins the hunt for food. C The cane toad was brought to Australiato kill pests fromAmerica70 years ago. D The toads move westward and northward because there is plenty of food there.

input: Please answer the following: Write a multi-choice question for the following article, with the given choices and answer: Article: Hong Kong businesses hit by nearly two months of illegal street occupations breathed a collective sigh of relief on Wednesday. Police finally cleared illegal protesters camped at the main intersection in the Mong Kok district, arresting two student leaders. More than 7,000 officers backed bailiffs (,)clearing occupied sections of Argyle Street and Nathan Road. The two-day operation saw 148 people arrested for various offenses, including contempt of court, resisting arrest, possession of offensive weapons, unlawful gathering and attacking police. The Chief Leader Stephen Hui said 22 officers were injured during the clearances. Police used pepper spray and batons to keep protesters from reclaiming cleared roads and from spreading the illegal occupation to neighboring streets. Six-lane Nathan Road, which goes through the heart of Kowloon, was cleared after nearly five hours. However, comments on the Internet said protesters were looking to reoccupy roads later in the evening. This week's actions mark the first time the authorities have successfully cleared one of the three main protest sites, which sprang up after demonstrators seized key intersections in late September to press for unconstitutional reforms. Contractor Kwan Sui-sum, 55, said he wished the Nathan Road clearance had come earlier, as he has had to pay HK$20,000 ($2,580) after the protesters delayed building reconstruction work. The owner of the Chung Hing Duty Free drug store was cautiously optimistic and eager for his store at the corner of the cleared intersection to get back to business. Sales dropped by 40 percent during the occupation, he said. "I'm not worried about the guess that the protesters will return. I trust in Hong Kong's rule of law and in the police," the man said, who wished to remain unknown as he fears attack from protesters. But five stores at a cleared site owned by jewelry chain Chow Tai Fook were still closed hours later. A company spokesman said the outlets will remain shut while it continues to monitor the situation. Options: A the Hong Kong police cleared the roads at a cost B all the Hong Kong citizens are doubtful about the result of the clearances C all the illegal protesters were willing to leave the protest sites D the Hong Kong government's attitude to the illegal protesters is unclear Answer: A the Hong Kong police cleared the roads at a cost Question:

I accepted the invitation, and I'm excited about going, but I'm a little nervous about it, too. The social customs in my country are different from those here, so I'm a little worried about making mistakes. Should I bring a gift, such as candy or flowers? Should I arrive on time or a little late? At the dinner table, how can I know which fork or knife to use? How can I let the family know that I'm thankful for their kindness? Yours, Knowing Nothing Dear Knowing Nothing, It's a good idea to bring a gift when you go to a dinner party. Flowers are always welcome, or you can bring a bottle of wine if you know the family drink it. You should arrive on time or five to ten minutes late. Don't get there early. If you are going to be more than fifteen minutes late, you should call and tell them. Try to relax at the dinner table. If you don't know how to use the right fork, knife or spoon, just watch the other guests, and follow them. If you still have no idea of what to do, don't be shy about asking the person next to you; it's better to ask them than to be silently uncomfortable and nervous. If you like the food, say so. Of course, you'll thank the host and hostess for the meal and for their kindness. It's also a good idea to send a card to thank them the day after. Yours, Betty Options: A relax at the dinner table B watch the other guests C ask the person beside him D keep silent at table Answer: D keep silent at table Question:
