Input: Sound waves are mechanical waves. They can travel only through matter. They cannot travel through empty space. This was demonstrated in the 1600s by a scientist named Robert Boyle. Boyle placed a ticking clock in a sealed glass jar. The clock could be heard ticking through the air and glass of the jar. Then Boyle pumped the air out of the jar. The clock was still running, but the ticking could not be heard. Thats because the sound couldnt travel without air particles to transfer the sound energy. Is there any other place where sound cannot be heard? Here is a hint: is there any other place that does not have air molecules? Thats right, in space sound cannot be transferred. So can astronauts hear each other? Yes, they can, because they are in enclosed space stations or pressurized suits.In both cases, they are surrounded by air molecules. If they left their space ship and did not use their electronics, they would not be able to hear each other. Next time you watch a science fiction movie, think about this factoid. When spaceships are destroyed by hostile alien beings, there would be no sound heard. Sound waves can travel through many kinds of matter.

Does the response "turned the watch off" correctly answer the question "In Boyle's experiment, what did he do to make the clock stop being heard while in the jar?"?

- no

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.

Question: "Name two examples of the effect of gravitational potential energy that are given in the paragraph."

OPTIONS:
- no
- yes

Answer: "Leaves fall, skateboarder moves downwards"

Response: yes

Earth processes have not changed over time. The way things happen now is the same way things happened in the past. Mountains grow and mountains slowly wear away. The same process is at work the same as it was billions of years ago. As the environment changes, living creatures adapt. They change over time. Some organisms may not be able to adapt. They become extinct. Becoming extinct means they die out completely. Some geologists study the history of the Earth. They want to learn about Earths past. They use clues from rocks and fossils. They use these clues to make sense of events. The goal is to place things in the order they happened. They also want to know how long it took for those events to happen.

Question: "What two things can happen to living organisms when the environment changes?"

Response: "They change"

- no

Problem: The Legal Services Corp. (LSC), a quasi-governmental agency that provides legal aid for the poor, would receive $329 million in fiscal 2004 under President Bush's proposal - the same amount requested in 2003 and approved for 2002 and 2001. If approved, the hold-the-line request for LSC means its budget would erode with inflation for another year, but it could be worse for the organization: Many conservatives fought for years to do away with the LSC altogether, saying legal services attorneys were spending too much time fighting for liberal causes or pursuing politically charged cases against the government instead of representing the needy. Opposition to the organization has cooled since 1996, when Congress approved restrictions (PL 104-134) on the sorts of cases federally funded legal aid attorneys can take. (1996 Almanac, p. 5-36) Republicans cut the organization's budget deeply in 1996, but its funding has recovered slowly. Last month, in the omnibus spending bill for fiscal 2003, the Senate added a onetime increase of $19 million, which, if approved in the final version, would bring the LSC budget to $348 million. The money would go to help states, such as Michigan and Ohio, that lost money when the organization redistributed its funding based on census counts made in 2000 of poor households. If the extra money survives a conference with the House and makes it to the president's desk, LSC supporters may try to include it in the organization's fiscal 2004 funding. The federal government began funding some programs to provide legal assistance to the poor in the late 1960s; the Legal Services Corporation was created in 1974 (PL 93-355). LSC gives nearly all its money to state and local agencies, which provide civil legal assistance to those whose income is less than 125 percent of the federal poverty level - $11,075 a year for an individual and $22,625 for a family of four. Funding for legal services goes to defend needy clients in domestic violence cases, custody cases and other such matters, according to LSC. Since 1996, lawyers who receive money from Legal Services have been prohibited from such activities as lobbying legislatures, filing class-action suits, participating in political demonstrations or strikes, pursuing abortion-related litigation, representing illegal aliens or prisoners, or defending public housing tenants evicted because they were charged with selling drugs

Question: "What has happened to the LSC's funding since the 1996 budget cut?"

Answer: "Its funding has recovered slowly"
