[Q]: Write a multi-choice question for the following article: Article: In the frozen continent of Antarctica scientists fear an alien invasion -- not from outer space, but carried in people's pockets and bags. Seeds and plants accidentally brought to Antarctica by tourists and scientists may introduce alien plant species which could threaten the survival of native plants in the finely balanced ecosystem. "The people that were carrying the most had lots and lots of seeds. They really were real threats," said Dana Bergstrom, from the Australian Antarctic Division. "When we take things in through hitchhiking then we get species which are competitive. The plants and animals there are not necessarily competitive, so we'd start losing various precious biodiversity on the (Antarctic) continent", Bergstrom told Reuters. Amongst the alien species discovered were the Iceland Poppy, and Annual Winter Grass -- all from cold climates and capable of growing in Antarctica. The Antarctic Peninsula, where most tourists travel, is now considered a "hot spot" on the frozen continent and the warmer the climate, the easier for seeds to grow. "The peninsula is warming at some of the greatest rates on the planet," said Bergstrom. The study, the first continent-wide assessment of invasive species in Antarctica, surveyed about 1,000 passengers during 2007-2008, the first year of the International Polar Year, an international effort to research the polar areas. Bergstrom said the one alien seed that had gained a foothold is Annual Winter Grass. It is a strong weed in the sub-Antarctic and is on the Antarctic island of King George. It has also made its way to the tail part of the Antarctic continent.

input: Please answer the following: Write a multi-choice question for the following article: Article: Back in old times, people had little knowledge about the universe and nature. Things we now consider to be common sense were mysteries to our ancestors. Over the years, major breakthroughs have been made in science and many phenomena have been explained. But still, there are always questions we can't yet answer, and The Guardian has listed some of them. 1. What makes us human? Just looking at your DNA won't tell you - human DNA is 99 percent _ to that of the chimpanzee and, believe it or not, 50 percent identical to a banana's! A lot of the things we once thought were unique about us - language and tool use, recognizing ourselves in the mirror and so on - have since been seen in other animals. Perhaps it's our culture that makes the difference or maybe our ability to use fire. It's also possible that our capacity for co-operation and our trading skills are what make us unique. 2. Why do we dream? Given the fact that we spend around a third of our lives sleeping, shouldn't we know everything about it? Unfortunately, scientists are still searching for a complete explanation of what happens when we sleep and why we dream. Austrian psychologist Sigmund Freud believed dreams were the expressions of wishes that we can't fulfill in our real lives. Others have wondered whether dreams are just random "noise" coming from a sleeping brain. 3. Could we someday live forever? Apart from accidents, most people die because of diseases that can be treated and aging. And since many diseases, such as diabetes and cancer, are diseases of aging, treating aging itself could be the key to extending our lives. Our knowledge of what causes us to age - and what allows some animals to live longer than others - is expanding rapidly. And though we haven't quite worked out all the details, we've worked out some pieces of the puzzles such as DNA damage and metabolism , which are all leading to the invention of drugs that can slow down the aging process. If we're lucky enough to lengthen our lives, we might even get to see the day when...

Problem: Write a multi-choice question for the following article: Article: An independent college claimed to have become the first school in England to make Chinese a compulsory subject for its pupils. Richard Cairns, the headmaster of Brighton College, said the move aims to recognize the importance of China as the world's fastest growing economy. Chinese will become one of the core subjects at the 1,200-pupil college from September. At present the school has only a "handful" of native Chinese students, but it hopes to attract more in the future. Mr Cairns, who made the announcement in his first week as head of the high-achieving college, said, "One of my key tasks is to make sure that the pupils at Brighton College are equipped for the realities of the 21st century, and one of those realities is that China has the fastest growing economy in the world. "China has replaced Britain as the world's fourth-largest economy. We in Britain need to face up to this challenge, see it for the trading opportunity that it is, and ensure that our nation's children are well-placed to thrive in this new global reality. "A better understanding of the language and culture of China will be hugely important to the advantage of the children of Brighton College." Mr Cairns said he hoped the Chinese children already at the college would help and encourage their fellow pupils to learn their language. In order to lead the way, Mr Cairns, a historian from Oxford, plans to take part in the first Chinese class as a pupil. "I have agreed to join the first Chinese class as a pupil. I think it is the best way for me to show the pupils here how important I regard this new addition to our core subjects."
