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.

Halting just outside the village, Harry formed his men with a front across the whole road, and directed the lines to advance, twenty yards apart. Then, placing himself at their head, he gave the word, and charged down the street upon the Roundheads. The latter, occupied by their attack upon the houses, were unconscious of the presence of their foe until he was close upon them, and were taken utterly by surprise. The force of the charge was irresistible, and the Roundheads, dispersed and on foot, were cut down in all directions. Groups of twos and threes stood together and attempted resistance, but the main body thought only of regaining their horses. In three minutes after the Royalists entered the village the surviving Roundheads were in full flight, hotly pursued by the victorious Cavaliers. These, being for the most part better mounted, overtook and slew many of the Roundheads, and not more than half the force which had set out returned to their quarters at Didcot. The pursuit continued to within half a mile of that place, and then Harry, knowing that there was a force of Roundhead infantry there, drew off from the pursuit, and returned to Chalcombe. He found that more than half of Sir Ralph Willoughy's men had been killed, many having been cut down before they could betake themselves to their arms, those quartered in the inn, and at two or three of the larger houses, having alone maintained a successful resistance until the arrival of succor.

Rakal, her first officer, was staring pensively at his panel. He was what this was all about. She watched his graceful fingers ending in thick black claws tap out calculations on the panel. His pointed ears swiveled back and forth, catching every sound from the bridge, while his long tail swished to the rhythm of his thoughts. Only those of the Arrallin Insurrection inner team knew he was no common 'beta furry'. His silken fur, which would be tawny golden and striped with jet black bands, was dyed perfectly to a pure black, and his mane trimmed and thinned as to be indistinguishable from the rest of his coat. His eyes had been treated and darkened to a rich purple to disguise the brilliant golden yellow color that would mark him as an Alpha Arrallin, and leader of his hive. Right now, he looked like an overgrown wolf who'd learned touch-typing. The scout ship re-emerged from the hole - a brilliant speck emerging from a sphere of velvety blackness. It's hail crackled across the comm, and Tara spun to retake her seat at the helm. "Launch the second probe. Won't Central be crushed to learn that another gateway has yielded little more than a class F planet and a white dwarf system. Level 1 and 2 staffers should prepare to be briefed and move out. This sounds like it's the one." The distinctive whuffle of pleasure rippled through the betas on the bridge, and Rakal let loose a small growl, as if to caution his charges against false hope. They'd scouted twenty-seven gates so far, and none had turned up anything worth the Insurrection's time. Tara would not let giddy hopes drag them onto a rock that would spell the end for the project, and the Arrallin species.

Question: "What was the mission all about?"

OPTIONS:
- no
- yes

Answer: "The mission was about Rakal and the Arrallin species"

Response: yes

On a day it celebrated 50 years of giving free legal advice, Southern Arizona Legal Aid announced it has received two grants totaling more than $7 million. One of the grants includes the creation of a Web site with legal advice for the poor. A three-year grant worth $6.6 million and a separate technology grant were announced at a press conference and dinner held Thursday at Evo. A. DeConcini Federal Courthouse, 405 W. Congress St. Deconcini was one of the organization's early board members. Thursday's celebration was the first public even held at the courthouse. About 100 members of the legal community attended, including state Attorney General Janet Napolitano and Arizona Supreme Court Justice Thomas Zlaket. Both grants come from the Legal Services., a private, nonprofit corporation established by Congress in 1974 to offer poor people equal access to the justice system. It's funded through congressional appropriation. The $6.6 million grant will pay for staffing operations. The Web site, which will be created with a $50,000 grant, is intended to offer legal advice to poor people across Arizona, said Paul Julian, chief executive officer of Southern Arizona Legal Aid. He said he wants every poor person in Arizona to have legal help. "This is another step in trying to realize that. We feel like we do a pretty good job of helping people who find us," Julian said. Julian said that though most people do not own computers, they can still access them at libraries, schools, and courthouses. He said the Web site will help bridge the "digital divide" that keeps the poor from using the Internet as a resource. Southern Arizona Legal Aid was founded in 1951 as the Legal Aid Society of the Pima County Bar Association. It offered free legal advice on civil matters including disputes in small claims court, divorce proceedings and obtaining Social Security benefits. Charles Ares, a member of the board of directors in the 1950s, said the office was kind of a charity operation.
