input question: Write a multi-choice question for the following article, with the given choices and answer: Article: Stepfamilies are commonplace in the United States and their number continues to grow.While stepfamilies differ widely in their make-up, they all consist of a parenting couple and children, one or more of whom is of a previous union.Such combinations of his kids, her kids, and then, possibly, kids of the new union make for complicated and often trying difficulties, more challenging than those of traditional families. Since stepfamilies involve more people and, consequently, more potential problems from the start than do childless new marriage, it is wise for the couple to do some careful planning prior to (=before) marriage.Not only do the prospective marital partners need agreement about their own carriers, life goals, finance and special interests, they must also prepare for new relationship with their children and attempt to accommodate their individual needs and feelings.Furthermore, there are often the rights of other relatives to consider. As for any family, the basic ingredient of a successful stepfamily are affection, kindness and mutual respect.However, love alone is not enough.Certainly love is the cornerstone upon which the foundation of any family is built, but there are also many other important ingredients involved in building a successful stepfamily.

By their very nature, stepfamilies often are complicated by past events that give rise to ambivalent loyalties, lingering hurts, fears,feelings of guilt and unrealistic dreams.The difficulties that arise within the stepfamilies are human and understandable.However, there are ways to confront and resolve them.For example, support groups and professional counselors ...

Write a multi-choice question for the following article, with the given choices and answer: Article: (Reuters)--A Malaysia Airlines flight carrying 227 passengers and 12 crew was presumed to have crashed off the Vietnamese coast on Saturday, and European officials said two people on board were using false identities. There were no reports of bad weather and no sign of why the Boeing 777-200ER would have vanished from radar screens about an hour after it took off from Kuala Lumpur for Beijing. "We are not ruling out any possibilities," Malaysia Airlines CEO Ahmad Jauhari Yahya told a news conference. By the early hours of Sunday, there were no confirmed signs of the plane or any wreckage, well over 24 hours after it went missing. Operations will continue through the night, officials said. There were no indications of sabotage nor claims of an attack. But the passenger list issued by the airline included the names of two Europeans--Austrian Christian Kozel and Italian Luigi Maraldi--who, according to their foreign ministries, were not in fact on the plane. A foreign ministry spokesman in Vienna said: "Our embassy got the information that there was an Austrian on board. That was the passenger list from Malaysia Airlines. Our system came back with a note that this is a stolen passport." Austrian police had found the man safe at home. The passport was stolen two years ago while he was travelling in Thailand, the spokesman said. The foreign ministry in Rome said no Italian was on the plane either, despite the inclusion of Maraldi's name on the list. His mother, Renata Lucchi, told Reuters his passport was lost, presumed stolen, in Thailand in 2013. U.S. and European security officials said that there was no proof of any terrorist link and there could be other explanations for the use of stolen passports. Options: A Uncertain. B Negative. C Positive. D Confident. Answer: A Uncertain. Question:
----
Answer: What was Ahmad Jauhari Yahya's attitude?

Problem: Given the question: Write a multi-choice question for the following article, with the given choices and answer: Article: An absolute description of the threat hanging over the world's mammals, reptiles, amphibians(, , ) and other life forms has been published by the well-known scientific journal, Nature. A special analysis carried out by the journal indicates that an astonishing 41% of all amphibians on the planet now face extinction while 26% of mammal species and 13% of birds are similarly threatened. Many species are already critically endangered and lose to extinction, including the Sumatran elephant, Amur leopard and mountain gorilla. But also in danger of vanishing for the wild, it now appears, are animals that are currently rated as merely being endangered. In each case, the finger of blame points directly at human activites The continuing spread of agriculture is destroying million of hectares of wild habitats every year, leaving animals without homes, while the introduction of newly-come species, often helped by humans, is also damaging native populations. At the same time, pollution and overfishing are destroying ocean ecosystems. "Habitat destruction, pollution or overfishing either skill off wild creatures and plants or leaves them badly weakened," said Derek Tittensor, an ocean ecologist at the World Conservation Monitoring Centre in Cambridge. "The trouble is that in coming decades, the additional threat of worsening climate change will become more and more common and could then kill off these survivors." The problem, according to Nature, is worsened because of the huge gaps in scientists knowledge about the planet's biodiversity. Evaluations of the total number of species of animals and plants alive vary from 2 million to 50 million. In addition, evaluations of current rates of species' disappearances vary from 500 to 36, 000 a year. "That is the real problem we face," added Tittensor. "The scale of uncertainty is huge." In the end, however, the data indicate that the world is heading cruelty towards a mass extinction-which is defined as one involving a loss of 75% of species or more. This could arrive in less...
