Input: The highest point of a wave is the crest. The lowest point is the trough. The vertical distance between a crest and a trough is the height of the wave. Wave height is also called amplitude. The horizontal distance between two crests is the wavelength. Both amplitude and wavelength are measures of wave size. The size of an ocean wave depends on how fast, over how great a distance, and how long the wind blows. The greater each of these factors is, the bigger a wave will be. Some of the biggest waves occur with hurricanes. A hurricane is a storm that forms over the ocean. Its winds may blow more than 150 miles per hour! The winds also travel over long distances and may last for many days.

Does the response "Because the faster wind speed will cause the wave to be larger than a slower wind speed" correctly answer the question "Other factors being equal, why would an ocean wave be larger if the wind were blowing 150 miles per hour than if it the wind were blowing 100 miles per hour?"?

Force is a vector. What then is a vector? Think about how you would give directions to a friend. You would not say, just walk half a mile. The person may walk a half mile in the wrong direction! More information is needed. You may say, follow this particular road for a half mile. You may say, look for the green house on Sumter St. In both examples, you provided a direction. You also gave the distance. In other words, you provided a vector. You did not just give a distance. Both pieces of information are needed to find a location. This is just like describing forces. To explain forces, both size and direction are needed. Notice the girl in Figure 1.1. She is pushing the swing away from herself. Thats the direction of the force. She can give the swing a strong push or a weak push.

Question: "If you know a force magnitude already, then what else do you need in order to give you the knowledge of a vector?"

OPTIONS:
- no
- yes

Answer: "Size of the object"

Response: yes

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.

Question: "What is the biggest obstacle NLS faced while trying to provide legal services to poor Asian populations?"

Response: "Language is their biggest obstacle,"

The Glory of Melaka: In the early days, if you were not a pirate or a mosquito, Melaka was not much of a place to live. The land was infertile, just a swampy plain, the river small and sluggish. But it had a sheltered harbor, protected from the monsoons by neighboring Sumatra. Later, the strategic location and deep-water channel close to the coast brought in the bigger vessels of the trade-wind traffic crossing the Indian Ocean. The first to realize the larger commercial potential, as so often throughout the country's subsequent history, were the Chinese. In 1409, under a new directive from Emperor Chu Ti to pursue trade in the South Seas and the Indian Ocean, a Chinese fleet of 50 ships headed by Admiral Cheng Ho called in at Melaka. They made Parameswara an offer he could not refuse: port facilities and an annual financial tribute in exchange for Chinese protection against the marauding Thais. In 1411, Parameswara took the money to Beijing himself, and the emperor gratefully made him a vassal king. Twenty years later, the Chinese withdrew again from the South Seas trade. The new ruler of Melaka, Sri Maharajah, switched his allegiance to the Muslim trading fraternity by marrying into the Muslim faith, wedding the daughter of a sultan in Sumatra. Islam won its place in Malaya not by conquestas had been the case in North Africa and Europebut by trade, dynastic alliances, and peaceful preaching. Bengali peddlers had already brought the faith to the east coast. In Melaka and throughout the peninsula, Islam thrived as a strong, male-dominated religion of individuality, offering dynamic leadership and preaching brotherhood and self-relianceall qualities ideally suited to the coastal trade. At the same time, Sufi mystics synthesized Islamic teaching with local Malay traditions of animistic magic and charisma, though Islam did not become the state religion until Muzaffar Shah became sultan of Melaka (14461459). But the key figure in the sultanate was Tun Perak, bendahara (prime minister) and military commander. He expanded Melaka's power along the west coast and down to Singapore and the neighboring Bintan islands. He also had orang laut pirates patrolling the seas to extort tribute from passing ships. After Ailied district chiefs had repelled assaults from Thai-controlled armies from Pahang, Tun Perak personally led a famous victory over a Thai fleet off Batu Pahat in 1456.
