Question: Article: Backpacking in Europe is a wonderful experience for young people around the world.After high school or university,you can plan a European backpacking trip. Packing As you plan the things you will carry,bring warm clothes and a raincoat or umbrella to deal with changing weather in different European countries.Europeans like dressing nicely,and good clothes will make you feel less like a dusty backpacker.It is not worth taking the trouble to bring a hair dryer or shampoo,as you can buy basic necessities in Europe. Hostels The cheapest places to sleep when backpacking in Europe are hostels(where people can stay and eat fairly cheaply).Most hostels have a lot of information about low-cost ways to see local attractions,and many offer tours.The cost for hostel beds differs from country to country.In Paris,you might pay 30 euros,but in Bulgaria,you can get a bed for 10 euros.In general,hostels are more expensive in large,popular cities such as Paris,Rome and London. Many backpackers use rail passes ,which allow unlimited travel within country groups over a period of time.If you have the time to travel by train and will be traveling in a country group,this can be a good deal.Otherwise,you may consider point-to-point tickets,local trains,buses and airlines such as Ryanair,easyJet and Wizz Air,which offer cheap flights. Food Eating out in Europe can come with a high cost,and the best way to cut your food budget is to cook meals in the shared kitchens in hostels.You can make several meals into picnics to take advantage of Europe's parks.When shopping for your picnic,try and buy at a local market.You save some euros while supporting the local industry at the same time.When eating out,choose restaurants away from tourist attractions.
Answer: They always ask the same price for their beds.

Question: Article: The young policeman, Constable Rider, walked more quickly than usual, because of the cold, but he did not consciously neglect any part of his work. His torch flashed on doorways and windows as he looked for anything that was at all suspicious, and when he ever thought that anything was unusual, he went to try the door and window, probably unheard by the people sleeping in the room just above his head. As he turned a corner, he heard a slight rustling sound -- it might be a cat, it could even be a dog, although few dogs wandered about at night. Rider saw nothing. A cat then? Usually if you disturbed a cat, it ran off and jumped, and you heard or noticed something else. By doing a lot of night, you learned to notice these things, but now all Rider noticed was the silence which had followed the rustling sound. So he acted cautiously. He did not flash his torch about the houses near the corner but walked on, and, a little way from the spot where he heard the sound, stopped and bent his head, as if he was lighting a cigarette. A policeman who stopped to light a cigarette seemed the most unsuspicious policeman in the world. There was still no sound. There were bushes in the garden of the house where Rider had first heard it and he knew that a man could hide there out of sight. But if he went back, it would warn any such man. So instead he stood and shone his torch at the window nearest him, and as if he had noticed something unusual, he walked towards it and opened the wooden gate, which made no sound at all. He reached the entrance and shone the torch on the keyhole of the front door -- and as he did so, the rustle came again, this time much more softly. He looked round quickly.
Answer: Looking for anything out of the ordinary.

Answer: What was Constable Rider doing on this very cold evening?

Question: Article: Some schools are now forbidding or restricting bake sales in an effort to fight a rise in obesity among kids. In February,the New York City Board of Education ordered that only fruits,vegetables,and approved packaged foods be sold at schools. Many students and parents objected to the restrictions on bake sales , which have long been a way to raise money for schools and community causes , including athletic events and Haitian earthquake relief.New York City finally compromised,allowing each school to hold one bake sale a month.But California and school districts in other states still limit bake sales.Should all schools forbid bake sales? Childhood obesity has been a growing problem for decades.The number of obese school-age children in the U.S.has increased by three times in the past 20 years.According to Eric Goldstein,the head of food services for New York City schools.40 percent of the city's 1.1 million pupils are obese. "We have a big problem in the city,state,and the country with obesity,"Goldstein said."During the school day, we have to focus on what is healthy for the mind and the body." A. J. Juarez, a community organizer for the Massachusetts Public Health Association,agrees.Restricting the kinds of food sold in schools is ''about teaching kids good habits,"he said. Nutrition experts believe schools are supposed to be a place where teachers and students set up a model environment, and the last thing kids need is an extra source of pointless calories. But many parents and students _ ."It's not fair. Bake sales have always been a positive way to raise money for school programs,and to make that against the rules is not appropriate," said a parent. "I don't think they should forbid bake sales,''Reese Butler,12,told The New York Times.A sixth-grader from Wrightstown,New Jersey,he reasoned that,"Money raised by selling cookies is sometimes used for field trips and for community causes,including Haitian earthquake relief." For Alyssa Howell,11,a fifth-grader in Ann Arbor, Michigan,the issue of choosing what to eat is about freedom."It is the child's decision to make the right choice."she said.
