[Q]: Article: A great-grandfather has put up his Christmas tree for the 85thtime after his father first bought it from a toy shop. Douglas Hewitt, 85, has celebrated every Christmas with the artificial tree since he was born. His father bought the tree from a toy shop in Sheffield just months after Douglas was born. The four-foot tree remains the centre point of the Hewitt family household during every festive season. Mr. Hewitt, of South Anston, South Yorkshire, said, "It reminds us of my childhood, our children's childhood and our grandchildren and great-grandchildren's after that. They all come and look at it and smile; it's become part of the furniture. If we didn't put that Christmas tree up, it wouldn't feel like Christmas." The tree was passed down to Mr. Hewitt when he married Mavis. Mrs. Hewitt said, "Year after year we have just carried on using that one. You have to be a bit more careful with it now, as it's _ ." Their daughter, June Murphy, also has fond memories of the Christmas tree. She said, "It was in my grandparents' home and then it was given to us. It looks a little thin now, as each time you get it out something else falls off. It's become a bit of a family joke. Each year someone has to comment 'not again!' But it's a Christmas tradition of getting the tree out that we all love. We'd all be sad to see it go, as I think it would be hard to find such a loved replacement." Mr. Hewitt said, "There were a lot more branches on it, and it's lost its feathers that were all along the edge. There were little candle holders on the ends and little legs on it, but unfortunately they've been lost over the years."
Question: Where did Douglas Hewitt get the Christmas tree?
Options: (A) He got it from his father. (B) He bought it from a toy shop. (C) He made it by himself. (D) He cut it down in a forest.

[Q]: Article: Have you ever imagined what the world will be in the near future? A recent study shows that the world in 2100 will be more crowded, more polluted and less stable ecologically than the world we live in now. Visible ahead is serious stress involving population, resource and environment. Despite greater food output, people in the world will be poorer in many ways than they are today. For hundred of millions of the extremely poor, the outlook for food and other necessities of life will be no better, for many it will be worse. While the economies of the developing countries are expected to grow at a faster rate than those of the industrialized nation, the total national product per head in most less developed countries remains low. The existing gap between the rich and poor nations will further widen. World food production is estimated to increase by 90 percent from 2000 to 2100. Most of that increase goes to the countries that already have higher per-head food consumption. Meanwhile, per-head consumption of food in the developing countries will scarcely improve or will actually fall far below the present inadequate level. What is worse is that prices for food are expected to double. As a result, many less developed countries will have increasing difficulties meeting energy needs. For the one quarter of mankind that depends primarily on wood for fuel, the outlook is not hopeful. Regional water shortage will become more sever. In the 1970-2100 period population growth will require twice as much water as it does today in nearly half the world. Still greater increases would be needed to improve standards of living. Development of new water supply will become more costly.
Question: According to the passage, in 2100 while output of food will be greater, _ .
Options: (A) people will have sufficient food supplies (B) the resource will become more than enough (C) in most developing countries people will have less food than they have today (D) the living standard of the world's population will improve greatly
