At about 2,189 miles, the Appalachian Trail is the longest single unit of the National Park System. With the number of people visiting this place increasing each year, the chances are great that any of us may damage the natural environment along the Trail and affect the experience for others. So please do your part by following these hiking and camping practices, and encourage others to learn about and adopt these techniques. 1 Plan ahead and prepare. Evaluate the risks associated with your outing, identify campsites and destinations in advance, and use maps and guides. Prepare for extreme weather, dangers, and emergencies - especially the cold - to avoid impacts from searches, rescues, and campfires. Learn when areas are most crowded and try to avoid those times. 2 Dispose of waste properly. Pack out all trash and food waste, including that left behind by others. Don't bury trash or food, and don't try to burn packaging materials in campfires. Use the privy for human waste only. Do not add trash. If there is no privy, dispose of human waste by burying it in a hole, a hole at least 200 feet (80 steps) from campsites, water sources and shelters, and well away from trails. 3 Leave what you find. Leave plants, cultural artifacts and other natural objects where you found them for others to enjoy. Do not damage live trees or plants; green wood burns poorly. Collect only firewood that is dead, down, and no larger than your wrist. Leave dead standing trees and dead limbs on standing trees for the wildlife. 4 Minimize campfire impacts. Use stoves for cooking - if you need a fire, build one only where it's legal and in an existing fire ring. Keep fires small. Never leave your campfire unattended, and drown it when you leave. Do not try to burn trash, including plastic, glass, cans, tea bags, food, or anything with food on it. These items do not burn thoroughly. They create harmful fumes , and attract wildlife like...

Ques: Read the article and select the best answer. Article: After a fortnight of extraordinary type, the much-feared computer virus that was supposed to strike the globe's hard drives last Friday simply fizzled. So many warnings were sounded that most computer owners either fed anti-virus programs into their systems or refused to turn the power on during the dreaded M-day. They dodged one disease, but more strains are on the way. The eponymous Friday-the-13th virus is due to strike this week, and the Maltese Amoeba may detonate on March 15. Who creates these things? A disproportionate number seems to originate in Bulgaria or Russia, where writing the smallest, most elegant virus programs has become a matter of quirky pride. Viruses are transmitted either by shared disks (as was Michelangelo) or over telephone lines. The virus program hides in a computer until, activated by a date, time, or some other trigger, it springs to life. The most common virus, Stoned, makes your screen announce: "Your computer is now stoned. Legalize marijuana. " (Regardless of your politics, you don't want this one around; it can damage your files inadvertently.) Solution: either keep your computer isolated--no trading disks, no on-line communication--or else install one of a dozen or so commercially available anti-virus programs that detect and delete the little time bombs. If they can come up with a virus that is hidden, will they next try to extort a business?--as in, pay me $1 million or my virus will destroy your system. In the meantime, money is being made by firms selling anti-virus programs. Egghead software stores logged a 3,000 percent jump in anti-virus sales. Was the threat overblown by the companies that make millions selling anti-virus software? Thanks to the media blitz, no one will ever know what might have happened--an unallied number of computer owners discovered and deleted Michelangelo before it was supposed to strike--on the artist's birthday. Question: Computer viruses are _ . Options: A: diseases spread from one computer to another by shared disks B: viruses hidden in a computer's instructions by the designers C: little time bombs hidden in a computer waiting to be triggered D: just those computer programs created by malevolent designers
Ans: D

It also provides children with a reading model. Reading aloud doesn't just benefit young children. Parents should continue reading aloud as their children grow because listening comprehension is more important than reading skills in middle school. Jim Trelease, in his Read-Aloud Handbook, has noted that almost as big a mistake as not reading to children at all is stopping too soon Until about the eighth grade, children listen and comprehend on a higher level than their reading skills allow them to read independently, This means children can hear and understand stories that are more difficult and more interesting than anything they can read on their own Question: In which part of a website can We find the text?
