Density is also an important physical property of matter. The concept of density combines what we know about an objects mass and volume. Density reflects how closely packed the particles of matter are. When particles are packed together more tightly, matter is more dense. Differences in density of matter explain many phenomena. It explains why helium balloons rise. It explains why currents such as the Gulf Stream flow through the oceans. It explains why some things float in or sink. You can see this in action by pouring vegetable oil into water. You can see a colorful demonstration in this video.

Question: "What are three examples of density given in the article?"

Answer: "How a rock falls off of a cliff"

Response: no

Early in chapter 5 we introduced, along with Khalid Sheikh Mohammed, two other men who became operational coordinators for al Qaeda: Khallad and Nashiri. As we explained, both were involved during 1998 and 1999 in preparing to attack a ship off the coast of Yemen with a boatload of explosives. They had originally targeted a commercial vessel, specifically an oil tanker, but Bin Laden urged them to look for a U.S.warship instead. In January 2000, their team had attempted to attack a warship in the port of Aden, but the attempt failed when the suicide boat sank. More than nine months later, on October 12,2000, al Qaeda operatives in a small boat laden with explosives attacked a U.S. Navy destroyer, the USS Cole. The blast ripped a hole in the side of the Cole, killing 17 members of the ship's crew and wounding at least 40. The plot, we now know, was a full-fledged al Qaeda operation, supervised directly by Bin Laden. He chose the target and location of the attack, selected the suicide operatives, and provided the money needed to purchase explosives and equipment. Nashiri was the field commander and managed the operation in Yemen. Khallad helped in Yemen until he was arrested in a case of mistaken identity and freed with Bin Laden's help, as we also mentioned earlier. Local al Qaeda coordinators included Jamal al Badawi and Fahd al Quso, who was supposed to film the attack from a nearby apartment. The two suicide operatives chosen were Hassan al Khamri and Ibrahim al Thawar, also known as Nibras. Nibras and Quso delivered money to Khallad in Bangkok during Khallad's January 2000 trip to Kuala Lumpur and Bangkok. In September 2000, Bin Laden reportedly told Nashiri that he wanted to replace Khamri and Nibras. Nashiri was angry and disagreed, telling others he would go to Afghanistan and explain to Bin Laden that the new operatives were already trained and ready to conduct the attack. Prior to departing, Nashiri gave Nibras and Khamri instructions to execute the attack on the next U.S.warship that entered the port of Aden.

Question: "What roles did Bin Laden, Khallad, and Nashiri have in al Qaeda?"

Answer: "Bin Laden managed the operation in Yemen"

Response: no

The Mummy 's Shroud is set in 1920 and tells the story of a team of archaeologists who come across the lost tomb of the boy Pharaoh Kah-To-Bey . The story begins with a flash back sequence to Ancient Egypt and we see the story of how Prem , a manservant of Kah-To-Bey , spirited away the boy when his father was killed in a palace coup and took him into the desert for protection . Unfortunately , the boy dies and is buried . The story then moves forward to 1920 and shows the expedition led by scientist Sir Basil Walden and business man Stanley Preston finding the tomb . They ignore the dire warning issued to them by Hasmid , a local Bedouin about the consequences for those that violate the tombs of Ancient Egypt and remove the bodies and the sacred shroud . Sir Basil is bitten by a snake just after finding the tomb . He recovers , but has a relapse after arriving back in Cairo . Preston takes advantage of this and commits him to an insane asylum , to take credit for finding the tomb and Prince 's mummy himself . Meanwhile , after being placed in the Cairo Museum , the mummy of Prem is revived when Hasmid chants the sacred oath on the shroud . The mummy then proceeds to go on a murderous rampage to kill off the members of the expedition , beginning with Sir Basil after he escapes from the asylum . One by one , those who assisted in removing the contents of the tomb to Cairo are eliminated by such grisly means as strangulation , being thrown out of windows , and having photographic acid thrown in their face .

Question: "What happens to Kah-To-Bey after Prem takes him into the desert?"

Answer: "He dies"

Response: yes

Boone, Ia. -Poor and elderly people may soon go without legal representation in Boone County. Boone County Legal Aid, which for 31 years has provided legal services to those who couldn't afford them, will close in February if a $10,000 grant from Prairie Meadows Racetrack and Casino is not awarded. The legal service is one of the few programs in Iowa that offers legal representation to those who qualify without turning to the state for its services. "It is a very sad situation, but that's the fact," said Alan Schroeder, city attorney and supervisor of Boone County Legal Aid. For the past two years using money mostly from the city and county, Schroeder has upheld the outfit alone, taking on about 60 clients a year, and settling cases that range from domestic abuse to bankruptcy. He also has a private practice. If the legal service closes, he's unsure where his clients will go. The city of Boone gave Schroeder $6,300 in July to resolve pending cases, said Kathy Berg, Boone's finance officer. Without that, the program might already be closed. "All governments are having problems with finances," Boone Mayor George Maybee said. "No one else stepped in. The county didn't. The state didn't." Donovan Olson, chairman of the county Board of Supervisors, said the board quit funding the legal service in July because it felt the county didn't need it. Drake University ended its funding after the 2000 spring semester "for a variety of reasons," Suzanne Levitt, the law professor who oversaw the program, said via e-mail. Olson said Schroeder must prove Prairie Meadows is the primary money source for the board to grant the program any more money. Schroeder ran the program without the help of law students or Drake, which had provided as much as two-thirds of the money in some years.

Question: "Where does Alan Schroeder work?"

Answer: "Private practice"
