Mandatory volunteering made many members of Maryland high school class of 1997 rumble with indignation. They didn’t like a new requirement that made them take part in the school’s community service program.

Future seniors, however, probably won't be as resistant now that the program has been broken in. Some, like John Maloney, already have completed their required hours of approved community service. The Bowie High School sophomore earned his hours in eighth grade by volunteering two nights a week at the Larkin-Chase Nursing and Restorative Center in Bowie. He played shuffleboard, cards, and other games with the senior citizens. He also helped plan parties for them and visited their rooms to keep them company. That experience inspired him to continue volunteering in the community.

John, 15, is not finished volunteering. Once a week he videotapes animals at the Prince George County animal shelter in Forestville. His footage is shown on the Bowie public access television channel in hopes of finding homes for the animals."Volunteering is better than just sitting around," says John, "and I like animals; I don't want to see them put to sleep. "

He's not the only volunteer in his family. His sister, Melissa, an eighth grader, has completed her hours also volunteering at Larkin-Chase. "It is a good idea to have kids go out into the community, but it's frustrating to have to write essays about the work," she said. "It makes you feel like you're doing it for the requirement and not for yourself."

The high school's service learning office, run by Beth Ansley, provides information on organizations seeking volunteers so that students will have an easier time fulfilling their hours. "It's ridiculous that people are opposing the requirements," said Amy Rouse, who this summer has worked at the Ronald McDonald House and has helped to rebuild a church in Clinton. "So many people won't do the service unless it's mandatory," Rouse said, "but once they start doing it, they'll really like it and hopefully it will become a part of their lives - like it has become a part of mine." 

Which of the following can be inferred from the passage about Melissa? 

A. She volunteers to help out at Larkin-Chase because it makes her feel good

B. She no longer volunteers at Larkin-Chase as she hates writing essays. 

C. She helps out at Larkin-Chase because it is a requirement of her course. 

D. She doesn’t like to volunteer there unless she is forced to do so by the school.

 After the United States purchased Louisiana from France and made it their newest territory in 1803, President Thomas Jefferson called for an expedition to investigate the land the United States had bought for $15 million. Jefferson’s secretary, Meriwether Lewis, a woodsman and a hunter from childhood, persuaded the president to let him lead this expedition. Lewis recruited Army officer William Clark to be his co-commander. The Lewis and Clark expedition led the two young explorers to discover a new natural wealth of variety and abundance about which they would return to tell the world.

 When Lewis and Clark departed from St. Louis in 1804, they had twenty-nine in their party, including a few Frenchmen and several men from Kentucky who were well-known frontiersmen. Along the way, they picked up an interpreter named Toussant Charbonneau and his Native American wife, Sacajawea, the Shoshoni “Bird Woman” who aided them as guide and peacemaker and later became an American legend.

 The expedition followed the Missouri River to its source, made a long portage overland though the Rocky Mountains, and descended the Columbia River to the Pacific Ocean. On the journey, they encountered peaceful Otos, whom they befriended, and hostile Teton Sioux, who demanded tribute from all traders. They also met Shoshoni, who welcomed their little sister Sacajawea, who had been abducted as a child by the Mandans. They discovered a paradise full of giant buffalo herds and elk and antelope so innocent of human contact that they tamely approached the men. The explorers also found a hell blighted by mosquitoes and winters harsher than anyone could reasonably hope to survive. They became desperately lost, then found their way again. Lewis and Clark kept detailed journals of the expedition, cataloging a dazzling array of new plants and animals, and even unearthing the bones of a forty-five-foot dinosaur.

 When the party returned to St. Louis in 1806 after travelling almost 8,000 miles, they were eagerly greeted and grandly entertained. Their glowing descriptions of this vast new West provided a boon to the westward migration now becoming a permanent part of American life. The journals written by Lewis and Clark are still widely read today.

It can be inferred that Sacajawea ________.

A. married a Shoshoni interpreter

B. abducted a child

C. demanded tribute from the traders

D. is a well-known American heroine
