Input: Mechanical energy is a combination of the energy of motion or position. This type of energy describes objects that are moving or could move. A moving ball can have energy from motion. An arrow can also have the energy of motion. Both are types of mechanical energy. Can you think of some other examples? Where does the energy of motion come from? It comes from the energy created by position. This energy is stored energy. This means it is not moving yet, but it has the potential to move. How can you store energy? The arrow gains energy from the drawn bow. As the arrow is released, the bow releases its stored energy and puts the arrow into motion. Can you think of some other ways to store energy using position?

Does the response "Mechanical" correctly answer the question "What type of energy do a moving arrow or ball have?"?

Input: Mr. Thorndike had risen, and, in farewell, was holding out his hand to Andrews. He turned, and across the court-room the eyes of the financier and the stenographer met. At the sight of the great man, Spear flushed crimson, and then his look of despair slowly disappeared; and into his eyes there came incredulously hope and gratitude. He turned his head suddenly to the wall. Mr. Thorndike stood irresolute, and then sank back into his chair. The first man in the line was already at the railing, and the questions put to him by the judge were being repeated to him by the other assistant district attorney and a court attendant. His muttered answers were in turn repeated to the judge. "Says he's married, naturalized citizen, Lutheran Church, die- cutter by profession." The probation officer, her hands filled with papers, bustled forward and whispered. "Mrs. Austin says," continued the district attorney, "she's looked into this case, and asks to have the man turned over to her. He has a wife and three children; has supported them for five years." "Is the wife in court?" the judge said. A thin, washed-out, pretty woman stood up, and clasped her hands in front of her. "Has this man been a good husband to you, madam?" asked the young judge. The woman broke into vehement assurances. No man could have been a better husband. Would she take him back? Indeed she would take him back. She held out her hands as though she would physically drag her husband from the pillory. The judge bowed toward the probation officer, and she beckoned the prisoner to her.

Does the response "He was a die-cutter by profession" correctly answer the question "What was the profession of the first man in line?"?

Input: 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.

Does the response "Protons have a positive charge" correctly answer the question "What kind of charge does a particle with more protons than electrons have?"?

Input: PHOTOGRAPH COLLECTING gains new stature as prices rise. Price records are being set at auctions this week. At Christie's, a folio of 21 prints from Alfred Stieglitz's "Equivalents" series sold for $396,000, a single-lot record. Other works also have been exceeding price estimates. In part, prices reflect development of a market structure based on such variables as the number of prints. This information used to be poorly documented and largely anecdotal, says Beth Gates-Warren of Sotheby's. "There is finally some sort of sense in the market," she says. Corporations and museums are among the serious buyers, giving greater market stability, says Robert Persky of the Photograph Collector. "When I see prints going into the hands of institutions, I know they aren't going to come back on the market." Most in demand: classic photographs by masters such as Stieglitz and Man Ray. But much contemporary work is also fetching "a great deal of money," says Miles Barth of the International Center of Photography.

Does the response "396" correctly answer the question "How many of Alfred Stieglitz's prints sold at a record price?"?
