Article: Taxpayers  in America pay less in income tax than many Europeans, according to a Pew Research Center report. Belgium has the highest income tax rate, at nearly 56 percent of income, according to the Organization for Economic Cooperation and Development, or OECD. Taxpayers in the U.S. pay less than 36 percent of their incomes into the national treasury. Taxes pay for services provided by the government. The U.S. ranks 25 of the 34 developed countries polled in the report. An unmarried person with no children was used as an example in the report. In America, an unmarried person, with no children, making the average wage of $50,000 in 2014 paid 24.8 percent of their income in federal   income tax and payroll taxes  . A similar person living in Belgium would pay 42.3 percent of their income. The average among the 39 countries in the poll was 27.3 percent income tax. The deadline to pay taxes in America is usually April 15. This year, the deadline is April 18. American taxpayers complain that wealthy people and large companies pay too little tax, according to a Pew Research Center poll from 2015. Americans pay tax to fund programs like Social Security and Medicaid, according to the Pew Research Center. Last year, American taxes paid for $888 billion in Social Security benefits. Social Security pays the elderly an income after they stop working. The government also paid more than $546 billion in Medicaid and Medicare benefits. Those programs pay for health and medical care to people who cannot afford it, according to the Center on Budget and Policy Priorities. 
 Answer: No countries in the world have a higher income tax than that in Belgium.

Article: Giant pandas are now extremely rare. Their number is less than 1,000 in the wild. The hunting of pandas has been banned for many years, so this is not the problem. Destruction of its habitat, when areas are cleared for growing crops, is one of the main reasons for panda's decline . Another reason is that the bamboo on which they mainly feed, is dying back. The pandas find it difficult to move to new feeding areas. As the bamboo disappears, the pandas simply starve to death.      Bamboo is a poor source of food, and pandas have to eat up 45kg of it every day, a process that takes them up to 16 hours. The process goes on day and night, with the pandas in a constant cycle of eating for eight hours and sleeping for four. They can eat other foods, but will rather starve than change their diet when bamboo is scarce.    Giant pandas are very good climbers, and use this skill to escape from the enemy. The giant panda lives alone for most of its life, only coming together with another of its species for long enough to mate. A newborn panda baby is born hairless and blind, is about 15cm long and weighs only 100g. The baby will stay with its mother for about 18 months, until it is able to set up its own territory       Chinese and American scientists are studying giant pandas and their habits in order to put in place a major conservation programme. Zoos around the world are taking part in panda breeding programmes. There is still hope that with human's help, the giant panda can survive in the wild. 
 Answer: Nearly 2 tons
How much bamboo does a panda eat every year?

Article: I have some work in Glasgow today. I was on a really tight schedule, which meant I would have no time for myself all day. I was having one of those days, the train was completely packed out and the conversation going on around me seemed to be particularly meaningless. On top of all that, I had a bit a headache. Walking quickly across the hall, I fished some change from my pocket. There was usually someone at the exit selling The Big Issue(a magazine that helps homeless folk earn a living). As the crowd parted ways at the bottom of the hall, I saw someone selling the Big Issue. You had to be homeless to sell the Big Issue. She really looked like she'd been sleeping rough. Her clothes were ragged and she was also rocking from side to side. At first I thought maybe she was trying to keep warm against the biting wind, But she wasn't ,she was moving in time to a tune. I couldn't hear her, but I could see her lips moving. As I got closer, I saw a white cane hanging from her elbow and noticed that she had sunken( ) eyes. She was blind, dirty and living on the streets. I came closer and through the noise of the traffic I heard her sing the immortal  line, "--and I think to myself, what a wonderful world!" I bought her last magazine for twice what I'd originally intended. She thanked me, then she picked up her stuff and went tapping off along the pavement--still singing! So, I have my happy memory for the day. And I think it will stay with me a long ,long time. Feel free to borrow it if you like. 
 Answer: Because they can't find a happy memory.
