Input: You may wonder if there are other examples of static discharge. The answer is yes. Lightning is a form of static discharge. It is much more dramatic than what happens between you and the door knocker, but it is the same principle. You can see how it occurs in the following diagram and animation. You have no doubt seen lightning in a rainstorm. What does lighting have to do with static electricity? As it turns out, everything! During a rainstorm, clouds develop regions of different charges. This happens due to the movement of air molecules, water drops, and ice particles. The negative charges are concentrated at the base of the clouds. The positive charges are concentrated at the top. The negative charges repel electrons on the ground below. The ground then becomes positively charged. Over time the differences increase. Eventually the electrons are discharged. This is what we see as lightning. You can watch an awesome slow-motion lightning strike below.

Does the response "Air molecules" correctly answer the question "What does lightning have to do with static electricity?"?

- no

Allan sat down at his desk and pulled the chair in close. Opening a side drawer, he took out a piece of paper and his inkpot. After filling his pen, Allan looked at his paper in the orange glow from the lantern set back in the desk's right-hand corner. His pen cast a forbidding line of shadow slanting across the page, echoing the inky darkness crouching in the edges of the lantern's struggling glow. The only other illumination came from a lurid moonlight filtered through thin branches and clouds, casting its bone-pale glow onto the pine floorboards. Allan unfolded another page, this one crowded with ranks of letters in tight formation from left to right. The lines of letters stepped into their divisions, in the shape of a story's outline: the loose, dry skeleton of a tale lay exposed beneath their feet, awaiting tendons, muscle and blushing skin. Allan reviewed the troops, all prepared to disembark, their task to form the tale of a young man returning home from Life Abroad to find his childhood friend a bride to-be, thus upsetting the apple cart of his life's plan, clarified of course by his very time away from her he loved best. Although the concept was a simple one, Allan thought it had potential. Besides, the public liked a good, simple romance. Perhaps this will be more saleable, he thought and began to write. They gazed at each other, lost in the rapture of love based so deeply within their hearts that they had never seen it before. "What about Roger?" she asked, knowing that the answer no longer mattered.

Question: "What phrases characterize the letters as a group of military men?"

OPTIONS:
- no
- yes

Answer: ""Allan reviewed the troops""

Response: yes

Surely, you have noticed the tall poles along the roadside. Do you know what is on top of those poles? Thats right, wires that carry electric current. These wires carry electric current to your home. But what is electric current? Electric current is actually the flow of electrons. You may recall, an electron is the outer-most particle in an atom. They have a negative charge. Electricity is the continuous flow of these particles. Electrons are able to move through wires. Their speed can even be measured. The SI unit for electric current (or speed) is the ampere (A). Ampere is often shortened to amp. Electric current may flow in just one direction, or it may keep reversing direction. Direct current (DC) flows in only one direction. Direct current is what is used in devices like flashlights. Alternating current (AC) flows in two directions. This is the type of current that flows into your home through wires.

Question: "Do electrons have a positive or negative charge?"

Response: "No"
OPTIONS:
- no
- yes

A: no

Problem: Iwasaki's careful respect for the Long Beach program and its lawyers earned him the political capital he needed to complete his takeover in a matter of weeks. "The Long Beach program had strong support in the community so in a situation like that, one has to recognize that it's not like a takeover where I have all the answers and I know best," Iwasaki said. "The people in the community who are working there have the contacts and the knowledge that will allow service to continue." Things have gone less smoothly across town. There, Dudovitz, a longtime poverty lawyer and executive director of the San Fernando Valley's 36-year-old legal aid program, continues to struggle with his hostile takeover of the neighboring San Gabriel-Pomona Valleys service area one year after it was accomplished. On the bright side, Dudovitz has extended his respected program to clients in the San Gabriel-Pomona Valley, and he now operates on a much larger budget, $6.5 million last year. However, his clash with the old San Gabriel program resulted in litigation, bitter feelings and a mission that some say is not clearly focused on serving poor people. "It was a difficult situation that was probably mishandled by everyone," a longtime observer of the public interest community said of the San Fernando Valley-San Gabriel-Pomona Valley merger. "There are very few people who come out as the heroes. Personalities got involved when they shouldn't have. Things were said that caused bad feelings and couldn't be unsaid." Iwasaki's merger with the smaller, 48-year-old Long Beach program was friendly and fast, and no one - not even Long Beach board members - lost a job. When it was over, Iwasaki had $1 million more in federal dollars and two new offices. Long Beach clients regained services they had lost years ago when federal budget cuts and dwindling grants reduced the staff of 15 lawyers to five and cut immigration and consumer law programs. Iwasaki said, "[I judged the transition] better than I could have hoped for."

Question: "What is the difference in the ages of the Long Beach and San Fernando Valley programs?"

Answer: "30 year"

Heat supplies the energy that causes motion. The deeper you go into toward the Earths core, the hotter it gets. At the core it is really hot. All that heat tries to rise toward the surface. In the Mantle, the rock is partially melted and is able to move. As it is heated, the material in the mantle moves toward the surface. As the mantle material rises, it cools. When it reaches the Earths crust, it is mostly stopped. A little of the material can break through the surface, but not all. Instead, it begins to move horizontally. The mantle material moves horizontally away from a mid-ocean ridge crest. Toward the surface, the mantle material starts to cool. As it cools it sinks back down into the mantle. These areas are where deep sea trench occur. The material sinks back down to the core. The system operates like a giant conveyor belt. The motion due to heating and cooling is called convection.

Question: "What happens to the cooled mantle material that does not break through the surface?"

Response: "It moves toward the surface"

- no
