Sound waves are mechanical waves. They can travel only through matter. They cannot travel through empty space. This was demonstrated in the 1600s by a scientist named Robert Boyle. Boyle placed a ticking clock in a sealed glass jar. The clock could be heard ticking through the air and glass of the jar. Then Boyle pumped the air out of the jar. The clock was still running, but the ticking could not be heard. Thats because the sound couldnt travel without air particles to transfer the sound energy. Is there any other place where sound cannot be heard? Here is a hint: is there any other place that does not have air molecules? Thats right, in space sound cannot be transferred. So can astronauts hear each other? Yes, they can, because they are in enclosed space stations or pressurized suits.In both cases, they are surrounded by air molecules. If they left their space ship and did not use their electronics, they would not be able to hear each other. Next time you watch a science fiction movie, think about this factoid. When spaceships are destroyed by hostile alien beings, there would be no sound heard. Sound waves can travel through many kinds of matter.

Problem: Tom plays pool in a deserted pool hall , pocketing two balls by lowdown means and then wakes Jerry up by shooting the 10-ball into the pocket where he is sleeping . Jerry awakes just in time to avoid the 10-ball and is carried out to the ball return , where the 10 and the 13 smash the mouse between each other . Jerry is mad and walks up through the pocket , first sees nothing , but after a few steps back to the pocket , he spots Tom perched behind it . Jerry tries to jump into another corner pocket , but Tom aims a cue ball with so much force that it roll's into the pocket , and spins back out of it and it rolls Jerry backwards to Tom , who has made a ramp with his cue stick for the mouse to slide up . Jerry stops at the top of the stick and is then blown down by Tom , who then shoots a stream of balls to make the mouse flat . The whole train rebounds back towards the cat and the balls stack up at Tom's end of the table . Tom shoots all the balls in succession with his cue , and then tries to shoot Jerry , but the mouse hangs onto the cue tip . The cat , as if he were saying '' Have it your way '' , chalks up and shoots the 8-ball using Jerry . The mouse drops off the cue tip and then is upended by the 8-ball rolling in circles , and Tom forces Jerry to jump through the ball rack as if he were a circus performer . Tom then sets it on fire to add an additional level of torment , and when Jerry accomplishes this with poise , Tom discards the flaming rack and shoots the 8-ball across the table and back .

Question:
(CNN) -- Guatemala's government has declared a state of siege and sent hundreds of troops to a northern province where officials say a Mexican drug gang is overtaking towns and threatening residents. President Alvaro Colom announced the 30-day emergency rule in Alta Verapaz on Sunday. The rule allows the military to order anyone suspected of conspiring against the government to be arrested and imprisoned without a warrant, the state-run AGN news agency said. "Starting today, combined forces will retake the streets of Alta Verapaz," a government statement released Sunday morning said. Government data shows cells of the drug gang known as Los Zetas are in the area to protect drug trafficking paths between Honduras and Mexico, "intimidating the population with their heavy weapons and threatening farmers to give up their land for criminal activities," AGN reported. The state of siege also allows the government to place greater restrictions on public gatherings, travel visas and gun licenses, among other things, according to AGN. "The population should be calm. What we are doing is not intended to persecute honest, working people," Interior Minister Carlos Menocal told reporters. Menocal said operations in the coming days would aim to boost regional security, regain control of territory, identify criminal gangs and capture their members. In an interview with CNN en Espanol last month, Menocal said his country needed more help from the United States to combat cartels, which were increasingly carving out new drug transport paths. "In the end, the large majority of drugs travel through Central America, and the assignment of resources or the financial support of the United States government is not the same as Colombia and Mexico receive," he said. Menocal said clashes between authorities and Los Zetas had notably increased. After reading the above, is "The population should remain calm because the actions are not meant to persecute honest working people" the correct answer to the question "Why should the population remain calm?"? OPTIONS:
- no
- yes

Answer:
yes

Input: Life for the partners of Cates, Katalinic & Lund holds little of the glamour one might expect from a career in law. Instead of lunches at Lutce, they caucus at the Palace Diner in Queens. Wooing clients means passing out fliers on street corners, not securing box seats at Madison Square Garden. To make ends meet, one partner stacks pipe and cleans the yard at a plumbing warehouse. Another handles urine samples in a hospital lab. A sign of failure, of a feeble economy, perhaps? Hardly. They are heeding the call of a growing pool of law schools, which are for the first time pointing graduates in a new direction and teaching them how to get there. Forget the lure of large firms, the security of a government post. Here is how to grapple "in the service of justice," as many of the schools put it, instead. Convinced that corporate largess and government programs barely dent the nation's legal needs, the law schools are urging graduates to buck tradition, pass up big salaries and ignore mushrooming student debt to join tiny neighborhood practices or simply start their own, all with an eye toward charging no more than their clients can afford. This is not pro bono legal work; it is "low bono," a term the schools coined to define the atypical kind of law career they are training students for. While its practitioners do charge for their services, they are also dead set on turning no one away - or at least as few as possible. "When you go into this kind of social justice law, it's really brutal and you're almost guaranteed to struggle for a couple of years before there's a light at the end of the tunnel," said Fred Rooney, director of the Community Legal Resource Network at City University of New York School of Law, from which the lawyers of the newly formed Cates, Katalinic & Lund graduated last May. "But if our graduates don't do it, the millions of people who cannot access justice in this country will continue to soar." The movement, primly called the consortium, started four years ago by CUNY, Northeastern University, the University of Maryland and St. Mary's Law School in Texas. (St. Mary's later dropped out.) Since then, it has drawn seven additional law schools to its ranks: the University of Michigan, Rutgers and Syracuse Law Schools, New York Law School, University of New Mexico School of Law, Thomas M. Cooley Law School and Touro Law School. It has elicited at least initial interest from 19 more.
