Question: 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. 

Question: "How did Robert Boyle prove how sound waves travel?"

- no

Problem: (CNN) -- Beyond skateboards, Silicon Valley and hippies, California has a trendsetting streak of a different kind. The state has been first to pass major public health initiatives that have spread throughout the country. California was first to require smog checks for clean air, pass anti-tobacco initiatives and bike helmets laws. While these laws were met with skepticism and ridicule, they've often become standard practice in other states. The Golden State was first to ban smoking in workplaces, bars and restaurants in 1998. Now similar rules exist throughout the country. Some advocates tout the state as a forward-thinking vanguard in which its health and safety laws are routinely emulated by other states. "There have been progressive legislations in tobacco, environment and obesity prevention," said Mark Horton, a lecturer at the University of California Berkeley School of Public Health. "In some respect, the rest of the country looks to California as a laboratory for moving forward with those various types of initiatives." But some critics liken the Golden State to a nanny state. California has 151,002 health and safety laws. "It never ends," said Laer Pearce, who works in public affairs in Orange County. "Every year, several hundred bills come through and dozens of them tell us how to live our lives." Starting in January, 760 new California laws went into effect -- for example, the importing of shark fins is prohibited, student athletes are required to have medical clearance after suffering a head injury, teens are banned from using tanning booths and the sale of caffeinated beer is forbidden. There's a perception that California has "more folks who are health-oriented and more health-minded," said Horton, former director of the California Department of Public Health. It's not just workout fanatics hanging out at Muscle Beach, Sierra Club members hiking mountains or the uber-health-conscious touting organic foods. Californians in general tend to have healthier habits, ranking 10th for physical activity, fourth for healthy blood pressure and fifth for a diet high in fruits and vegetables compared with other states, according to America's Health Rankings. 

Question: "What are some of California's trendsetting practices?"

Question:
His exile lasted nearly a year and a half. Long before that time there had come a reaction in his favour. The new consuls were well disposed towards him; Clodius's insolence had already disgusted Pompey; Caesar was absent with his legions in Gaul; his own friends, who had all along been active in his favour (though in his querulous mood he accused them of apathy) took advantage of the change, his generous rival Hortensius being amongst the most active; and all the frantic violence of Clodius and his party served only to delay for a while the return which they could not prevent. A motion for his recall was carried at last by an immense majority. Cicero had one remarkable ally on that occasion. On one of the days when the Senate was known to be discussing his recall, the 'Andromache' of Ennius was being played in the theatre. The popular actor Esop, whose name has come down to us in conjunction with that of Roscius, was playing the principal character. The great orator had been his pupil, and was evidently regarded by him as a personal friend. With all the force of his consummate art, he threw into Andromache's lament for her absent father his own feelings for Cicero. The words in the part were strikingly appropriate, and he did not hesitate to insert a phrase or two of his own when he came to speak of the man  After reading the above, is "Cesar" the correct answer to the question "When the recall was carried at last by an immense majority.who was a remarkable ally on that occasion?"? OPTIONS:
- no
- yes

no
Fossils may form in other ways. Fossils can be preserved almost completely. In this process, the organism doesnt change much. As seen below, tree sap may cover an organism. With time, the sap hardens. It turns to into amber. The original organism is preserved. This is very exciting for scientists. They are able to study the DNA of the organism that no longer lives on Earth. Some animals have been found frozen in ice. Others have been found in tar pits after falling in. Molds and casts are another way organisms can be fossilized. Have you ever walked in soft mud and left footprints? Once in a while, these traces of organisms can be preserved. In this case, nothing is left of the organism. A mold is an imprint of an organism that is preserved in rock. The organisms remains break down completely. There is nothing left of the original plant and animal. 

Question: "How can fossils be completely preserved?"

OPTIONS:
- no
- yes

Answer: "Through mold, ice, or amber"

Response:
Answer: yes
