Magnetism is the ability of a material to be attracted by a magnet. It also include the ability for some material to act like a magnet. No doubt youve handled refrigerator magnets. You can see some in Figure 1.28. You probably know they stick to a metal refrigerator. This is what holds your homework up. Maybe your little sisters drawings are hung on the fridge in this manner. Do magnets stick to all materials? Of course not. You have probably checked and they do not stick to other surfaces. They do not stick to wooden doors or glass windows. Wood and glass are not attracted to a magnet. Obviously, only certain materials are attracted to magnets.

Rakal, her first officer, was staring pensively at his panel. He was what this was all about. She watched his graceful fingers ending in thick black claws tap out calculations on the panel. His pointed ears swiveled back and forth, catching every sound from the bridge, while his long tail swished to the rhythm of his thoughts. Only those of the Arrallin Insurrection inner team knew he was no common 'beta furry'. His silken fur, which would be tawny golden and striped with jet black bands, was dyed perfectly to a pure black, and his mane trimmed and thinned as to be indistinguishable from the rest of his coat. His eyes had been treated and darkened to a rich purple to disguise the brilliant golden yellow color that would mark him as an Alpha Arrallin, and leader of his hive. Right now, he looked like an overgrown wolf who'd learned touch-typing. The scout ship re-emerged from the hole - a brilliant speck emerging from a sphere of velvety blackness. It's hail crackled across the comm, and Tara spun to retake her seat at the helm. "Launch the second probe. Won't Central be crushed to learn that another gateway has yielded little more than a class F planet and a white dwarf system. Level 1 and 2 staffers should prepare to be briefed and move out. This sounds like it's the one." The distinctive whuffle of pleasure rippled through the betas on the bridge, and Rakal let loose a small growl, as if to caution his charges against false hope. They'd scouted twenty-seven gates so far, and none had turned up anything worth the Insurrection's time. Tara would not let giddy hopes drag them onto a rock that would spell the end for the project, and the Arrallin species.

Question: "Why were the betas excited on the bridge?"

Response: "They had received a huge amount of money"

Problem: (CNN) -- Declaring 2010 "The best year in safety performance in our company's history," Transocean Ltd., owner of the Gulf of Mexico oil rig that exploded, killing 11 workers, has awarded its top executives hefty bonuses and raises, according to a recent filing with the U.S. Securities and Exchange Commission. That includes a $200,000 salary increase for Transocean president and chief executive officer Steven L. Newman, whose base salary will increase from $900,000 to $1.1 million, according to the SEC report. Newman's bonus was $374,062, the report states. Newman also has a $5.4 million long-term compensation package the company awarded him upon his appointment as CEO in March 2010, according to the SEC filing. The latest cash awards are based in part on the company's "performance under safety," the Transocean filing states. "Notwithstanding the tragic loss of life in the Gulf of Mexico, we achieved an exemplary statistical safety record as measured by our total recordable incident rate and total potential severity rate," the SEC statement reads. "As measured by these standards, we recorded the best year in safety performance in our Company's history." The company called that record "a reflection on our commitment to achieving an incident-free environment, all the time, everywhere," the SEC filing states. The company did not respond to an e-mail from CNN seeking comment. The April 20, 2010, explosion on the Deepwater Horizon rig injured 17 workers and killed 11 others, including nine Transocean employees, according to the SEC filing. It has been called the worst spill in U.S. history. The well was capped three months later, but not before millions of barrels of oil spilled into the Gulf. In January, President Barack Obama's National Commission on the BP Deepwater Horizon Oil Spill and Offshore Drilling released a report that spread blame for the accident among Transocean, BP -- which leased the rig -- and Halliburton, which installed the rig's cement casing.

Question: "What was the worst oil spill in U.S. history?"

Answer: "The 2010 Deepwater Horizon rig explosion at the Gulf of Mexico"

Alien Planet starts out with an interstellar spacecraft named Von Braun , leaving Earth's orbit . Traveling at 20 % the speed of light , it reaches Darwin IV in 42 years . Upon reaching orbit , it deploys the Darwin Reconnaissance Orbiter , Which looks for potential landing sites for the probes . The first probe , Balboa , explodes along with its lifting body transport during entry , because one of its wings failed to unfold . Two backup probes , Leonardo da Vinci and Isaac Newton , successfully land on the planet , and learn much about its bizarre indigenous lifeforms , including an apparently sapient species . The robotic probes sent out to research on Darwin IV are called Horus Probes . Each Horus probe consists of an { { convert } } long inflatable , hydrogen-filled balloon , Which is covered with solar receptors , a computer ' brain ' , a ' head ' covered with sensors , and several smaller robots that can be sent to places too dangerous for the probes themselves . The probes have a limited degree of artificial intelligence , very similar to the ' processing power ' of a 4-year-old . All the real thinking is done by a supercomputer in the orbiting Von Braun . The probes are programmed with different personalities ; Ike is more cautious , while Leo is the risk-taker . The two probes are also equipped with a holographic message that will be projected to any sentient life found on Darwin . After the two probes inflate their gas-bags , they encounter a voracious Arrowtongue and watch it pursue a Gyrosprinter .

Question: "Where does the Von Braun spacecraft deploy upon reaching orbit?"

OPTIONS:
- no
- yes

Answer: "Darwin Reconnaissance Orbiter"

Response:
yes
