Please answer this: Write a multi-choice question for the following article, with the given choices and answer: Article: "The world has never been a better place to live in" says science writer Matt Ridley, "and it will keep on getting better." Read on to see how Ridley makes his case. Right or wrong? You decide. Compared with 50 years ago, when I was just four years old, people now make nearly three times as much money, eat one third more food and expect to live one third longer. In fact, it's hard to find any areas of the world that's worse off now than it was then, even though the world population has more than doubled over that period. One reason we are richer, healthier, taller, cleverer, longer-lived and freer than ever before is that the four most basic human needs--food, clothing, fuel and shelter--have grown much cheaper. Take one example: In 1800, a candle providing one hour's light cost six hours' work. In the 1880s, the same light from a lamp took 15 minutes' work to pay for. In 1950, it was eight seconds. Today, it's half a second. In these terms, we are 43,200 times better off than in1800. In the United States, rivers, lakes, seas and air are getting cleaner all the time. A car today produces less pollution traveling at full speed than a parked car did from leaks in 1970. Although the world population is growing, the rate of increase has been falling for 50 years. Across the world, national birth rates are lower now than in 1960, and in the less developed world, the birth rate has almost halved. According to a research report from the United Nations, population will start falling once it reaches 9.2 billion in 2075. After all, there are already seven billion people on earth, and they are eating better and better. In 1970s, there were 550 billion barrels of oil reserves in the world, and in the 20 years that followed the world used up 600 billion. So by 1990, reserves should have been overused by 50 billion barrels. Instead, it is reported there are 900 billion today. They will last for many years and people will find something in place of oil long before they run out. The more we develop, the more we can... Options: A Things we used to need were much cheaper than they are today. B The pollution today is much more serious than it was long ago. C Population problem has nearly made the world stop developing. D It's not necessary to be worried about oil reserves in the world. Answer: D It's not necessary to be worried about oil reserves in the world. Question:
