Static electricity is like a teeter-totter. What happens if a teeter-totter is balanced? Correct! It does not move. What about when its not balanced? Yes, it will now begin to move. Charges move when they are not balanced. Charges can build up by friction. Maybe you rub your feet on a wool mat or carpet. Rubber soled shoes readily gain charges. The wool carpet easily gives up charges. The two items become unbalanced. One item has a positive charge. The other has a negative charge. The difference in charge is called static electricity. Just like the teeter-totter, something is going to move. Positive charges build up on the mat. Negative charges build up on you. 

Question: "What two types of charges build up in unbalanced items?"

OPTIONS:
- no
- yes

Answer: "Negative Charge and Positive Charge"

Response: yes
Electric charge is a physical property. It occurs between particles or objects. It causes them to attract or repel each other. They do not even have to touch. This is unlike the typical push or pull you may be familiar with. All electric charge is based on the protons and electrons in atoms. A proton has a positive electric charge. An electron has a negative electric charge. Forces on Charged Objects Most atoms are balanced electrically. They have the same number of positive and negative charges. Therefore, the number of protons equals the number of electrons. Neutrons do not matter as they have no charge. When an object loses some electrons, it becomes positively charged. There are now more protons than electrons inside the atom. The lost electrons may remain free. Or, they may attach to another object. The new object now has more electrons than protons. It then becomes negatively charged. 

Question: "How will increasing neutrons affect the particle's charge?"

Response: "No change"
OPTIONS:
- no
- yes

Problem: An archaeological party explore some caverns underground .  Dr. Campbell and Dr. Hughes are the two leaders of the archaeological expedition , and get separated .  While Dr. Hughes finds an alien corpse with a fossilized diamond , Dr. Campbell finds hieroglyphics at the cost of the party except for Hughes and himself .  Two years later , Campbell and his assistant Holly are digging up the bones of Yonggary , a gargantuan dinosaur 50 times the size of a tyrannosaurus rex .  Out of nowhere , people slowly are being killed around the site .  While Holly is working Dr. Hughes , who has been legally dead for 2 years , goes to Holly and tells her to stop the dig .  Dr. Campbell comes into the tent and sends Dr. Hughes off .  Holly quits the expedition when another `` Accident '' occurs .  In the town bar , Dr. Hughes finds Holly and takes her back to her Hotel room to tell her why he thinks the bones of the Dinosaur , Which he calls Yonggary , are going to bring the end of the world .  After explaining , Holly and Hughes go to the site to stop Campbell but it is too late and Aliens resurrect Yonggary .  After Yonggary's first appearance , the Army comes in and takes Holly and Campbell to an army base when Yonggary is dispatched by the aliens again .  The army sends choppers after Yonggary , but he destroys them .  Yonggary is then sent to the city and does some damage , where some jets attack him .  Then Yonggary is transported to a power plant where he is attacked by rocket pack soldiers .  During the fight , Hughes and Holly find out that the diamond on Yonggary's forehead is the device giving the aliens control of Yonggary . 

Question: "What happens when Campbell and Holly are digging up Yonggary's bones?"

Answer: "Dr. Hughes tells Holly to stop the dig"

OPTIONS:
- no
- yes
Answer: yes
Question:
(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.  After reading the above, is "Ban of marijuana" the correct answer to the question "What are some major public health initiatives that California pioneered?"? OPTIONS:
- no
- yes

Answer:
no
The factory is highly automated and designed to shift flexibly to produce many different kinds of chips to suit demand. "The diversity is the big difference with this plant," said Richard Doherty, president of Envisioneering, a research firm. "It gives IBM the capability to make so many different kinds of custom chips, and the world is going to custom chips." The 140,000-square-foot plant is a testament to advanced manufacturing technology. The 300-millimeter silicon wafers -- about the size of a standard pizza -- are shuttled around the facility in enclosed plastic pods, which ride on overhead tracks. They drop down from wires automatically into machines, sheathed in stainless steel and glass, for each stage of processing and fabrication. Throughout the 500 processing steps, which typically last 20 days, the wafers are not touched by human hands. The circuits etched into the chips are less than one thousandth the width of a human hair. Human operators are there to monitor the systems, catch errors and fine-tune the production process for maximum efficiency. Because each of the hundreds of processing machines is self-enclosed, and essentially airtight, the uniforms operators wear are less constricting than in the previous generation of chip plants, which looked like space suits. The operators at the East Fishkill factory wear light nylon uniforms, light blue shoe coverings and translucent hair nets made of paper. They look more like workers in a bakery. Yes, said Richard Brilla, director of the new facility, "but the donuts are a lot more costly here." Each wafer, holding hundreds of chips, is worth $6,000 to $10,000 apiece, depending on what insulation, circuitry and materials are used. 

Question: "What are the steps that are required for every stage of fabrication?"

OPTIONS:
- no
- yes

Answer: "20"

Response:
no
