[EX Q]: When land is cleared, habitats are lost. It may be cleared for agriculture. It may also be used for building new homes or businesses. Within the past 100 years, the amount of land used for agriculture has almost doubled. Land used for grazing cattle has more than doubled. Many wetlands have also been lost to agriculture. The U.S. has lost almost all the natural tall-grass prairies. Thee areas of tall thick grass have virtually disappeared. These areas of land had thick fertile soil. Their grasses had very deep root systems. These deep and thick roots reduced the amount of soil erosion. They also were home to many plants and animals. Prairies were wonderful places. They were home to colorful flowers, prairie dogs, and herds of bison. <sep>How can habitats be lost?<sep>killed by invasive tall grass
[EX A]: No

[EX Q]: After more than a year of effort, attorneys with Northwest Justice Project earlier this week told 25 families in a mobile home park here that they can keep their homes and no longer need to fear eviction. The East Wenatchee City Council has entered into an Interlocal Agreement with the Wenatchee Housing Authority authorizing the Authority to purchase and maintain the Mobile Park Plaza mobile home park. Located just north of the Wenatchee Valley Mall, the park had been threatened with closure for more than a year. "We cannot say enough about how relieved we are that this is over," said Manuel Luna, one of the residents of Mobile Park Plaza. "We were afraid that no solution would be found, and that our families would have no place to go. We are very grateful for the help of our attorneys. Without them, we would not have saved our homes. We are also thankful for the help of the Housing Authority, the City Council and Mayor Steve Lacy." Formerly owned by local businessman Dan Jennings, Mobile Park Plaza had been home to 45 low-income families, many of them Latino farm workers. In October 2000 Jennings gave the park residents notice of his intent to close the park effective November 30, 2001. While some park residents decided to move, others, including 25 families, organized an informal association to relocate or save their homes. Unable to afford private legal counsel, the families asked for help from legal services attorneys at the Northwest Justice Project and Columbia Legal Services. In the succeeding months, these attorneys worked with representatives of the Greater Wenatchee Housing Authority, the state Office of Community Development, Chelan County, the City of East Wenatchee, state legislators, Jennings and others to secure funding and find a solution. "There seemed to be a never-ending set of obstacles," said Patrick Pleas, an attorney with Northwest Justice Project. "Mr. Jennings had financial considerations, the City had growth and economic development considerations, and the State and Housing Authority had their own concerns. Thankfully, hard work and good will from all parties allowed us to find a solution that works for everyone." Northwest Justice Project and Columbia Legal Services are non-profit organizations that provide civil legal assistance to low-income individuals and families throughout Washington state. Members of the state's Access to Justice Network, these organizations work with thousands of volunteer attorneys to ensure that justice is available to those who face critical legal problems and can't afford private legal counsel. <sep>Why did some residents of Mobile Park Plaza decide to move?<sep>Because Jennings gave the park residents notice of his intent to close the park
[EX A]: Yes

[EX Q]: The idea that Earth is a magnet is far from new. It was first proposed in 1600 by a British physician named William Gilbert. Knowing it acts like a magnet is one thing. Knowing why it acts like a magnet is more difficult. In fact, finding out why is a fairly recent discovery. To find out why required new technology. It was the seismograph that made it possible to learn why the Earth acted like a magnet. Seismograph are used to study earthquakes. By studying earthquake waves they were able to learn about Earths interior. They discovered that Earth has an inner and outer core. The outer core consists of liquid metals, mainly iron and nickel. Scientists think that Earths magnetic field is generated here. It is caused by the motion of this liquid metal. The liquid metal moves as Earth spins on its axis. <sep>What do scientists think to be the immediate cause of how Earth's magnetic field is generated? Choose the relevant options<sep>They discovered that Earth has an inner and outer core
[EX A]:
No
