Input: Gravitational Potential Energy is affected by position. Like the leaves on trees, anything that is raised up has the potential to fall. It has potential energy. You can see examples of people with gravitational potential energy in 1.5 Figure below. Gravitational potential energy depends on two things. It depends on its weight, because a large falling rock can do more damage than a leaf falling from a tree. It also depends on its height above the ground. Like the skateboarder, the higher the ramp, the faster he will be going when he reaches the bottom. Like all energy, gravitational potential energy has the ability to do work. In this case, weight has the potential to deliver a force. More important for us is that it has the ability to cause change. What kind of change you may ask? Gravitational potential energy has the ability to cause motion.

Does the response "Motion" correctly answer the question "What is the most important change gravitational potential energy can have?"?

Input: Alexander earned the epithet "The Great" due to his unparalleled success as a military commander. He never lost a battle, despite typically being outnumbered. This was due to use of terrain, phalanx and cavalry tactics, bold strategy, and the fierce loyalty of his troops. The Macedonian phalanx, armed with the sarissa, a spear 6 metres (20 ft) long, had been developed and perfected by Philip II through rigorous training, and Alexander used its speed and maneuverability to great effect against larger but more disparate Persian forces. Alexander also recognized the potential for disunity among his diverse army, which employed various languages and weapons. He overcame this by being personally involved in battle, in the manner of a Macedonian king. In his first battle in Asia, at Granicus, Alexander used only a small part of his forces, perhaps 13,000 infantry with 5,000 cavalry, against a much larger Persian force of 40,000. Alexander placed the phalanx at the center and cavalry and archers on the wings, so that his line matched the length of the Persian cavalry line, about 3 km (1.86 mi). By contrast, the Persian infantry was stationed behind its cavalry. This ensured that Alexander would not be outflanked, while his phalanx, armed with long pikes, had a considerable advantage over the Persian's scimitars and javelins. Macedonian losses were negligible compared to those of the Persians. At Issus in 333 BC, his first confrontation with Darius, he used the same deployment, and again the central phalanx pushed through. Alexander personally led the charge in the center, routing the opposing army. At the decisive encounter with Darius at Gaugamela, Darius equipped his chariots with scythes on the wheels to break up the phalanx and equipped his cavalry with pikes. Alexander arranged a double phalanx, with the center advancing at an angle, parting when the chariots bore down and then reforming. The advance was successful and broke Darius' center, causing the latter to flee once again. When faced with opponents who used unfamiliar fighting techniques, such as in Central Asia and India, Alexander adapted his forces to his opponents' style. Thus, in Bactria and Sogdiana, Alexander successfully used his javelin throwers and archers to prevent outflanking movements, while massing his cavalry at the center.

Does the response "Being outnumbered" correctly answer the question "Why was Alexander considered a military leader of unparalleled success?"?

Input: Neighborhood Legal Services, which provides free legal services to the poor, has expanded into the San Gabriel and Pomona valleys, areas with large Asian populations, many of whom speak limited or no English. Language is their biggest obstacle, but the Asian communities' cultural isolation and service providers' lack of cultural expertise also play a part, said NLS executive director Neal Dubovitz. And with 13 percent to 15 percent of the Asian population in the U.S. living below the poverty line, NLS services are badly needed, Dubovitz said. "Although it is a significant part of the poverty population, Asians historically have not been able to participate in the services and programs available to the poor," he said. From simple telephone advice to complete legal representation in court, the agency provides free consumer, health, family, immigration, housing, public benefits and labor legal services to people who earn under $1,380 per month. Legal service providers have long served large Latino populations, who have cultural diversity but share a common language. "I remember the days when there were only a handful of people in the legal offices who spoke Spanish," Dudovitz said. "Now Spanish and English are interchangeable. Our goal is to have that for the major Asian languages as well." Before the expansion, only a few NLS lawyers spoke Asian languages, said attorney Rebecca Yee, who was hired by NLS in April 2002 to design and head the project. "Now we have people speaking Cantonese, Mandarin, Thai, Khmer (from Cambodia), Korean, Vietnamese, Japanese and Tagalog," Yee said. One of the 13 attorneys hired to work with the program is Irene Mak, a family law attorney who speaks Cantonese, Mandarin and Thai. Mak was a partner at a private law firm before she went to work for NLS two years ago, earning up to $20,000 less a year working on domestic violence cases. "The job is more satisfying than the money," said Mak, who grew up in Hong Kong and Thailand before coming to the United States. "I could use my language skills and wanted to give back to the Asian community." NLS expanded when Legal Services Corp., the federal agency that funds providers of free legal services nationwide, reduced the number of grantees in the Los Angeles area from five to three, Dudovitz said. NLS won the competitive grant over the Legal Services Program for Pasadena, San Gabriel-Pomona valleys. That boosted its client base from 16,000 to around 25,000, and NLS opened an office in El Monte.

Does the response "Qualified Staff" correctly answer the question "What obstacles does Neighborhood Legal Services face? Name at least one"?

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 "When there are more protons than electrons inside the atom" correctly answer the question "Why does an object's charge become positive?"?
