Problem:  Bin Laden reportedly discussed the planes operation with KSM and Atef in a series of meetings in the spring of 1999 at the al Matar complex near Kandahar. KSM's original concept of using one of the hijacked planes to make a media statement was scrapped, but  Bin Laden considered the basic idea feasible.  Bin Laden, Atef, and KSM developed an initial list of targets. These included the White House, the U.S. Capitol, the Pentagon, and the World Trade Center. According to KSM,  Bin Laden wanted to destroy the White House and the Pentagon, KSM wanted to strike the World Trade Center, and all of them wanted to hit the Capitol. No one else was involved in the initial selection of targets.  Bin Laden also soon selected four individuals to serve as suicide operatives: Khalid al Mihdhar, Nawaf al Hazmi, Khallad, and Abu Bara al Yemeni. During the al Matar meetings,  Bin Laden told KSM that Mihdhar and Hazmi were so eager to participate in an operation against the United States that they had already obtained U.S. visas. KSM states that they had done so on their own after the suicide of their friend Azzam (Nashiri's cousin) in carrying out the Nairobi bombing. KSM had not met them. His only guidance from  Bin Laden was that the two should eventually go to the United States for pilot training. Hazmi and Mihdhar were Saudi nationals, born in Mecca. Like the others in this initial group of selectees, they were already experienced mujahideen. They had traveled together to fight in Bosnia in a group that journeyed to the Balkans in 1995. By the time Hazmi and Mihdhar were assigned to the planes operation in early 1999, they had visited Afghanistan on several occasions. Khallad was another veteran mujahid, like much of his family. His father had been expelled from Yemen because of his extremist views. Khallad had grown up in Saudi Arabia, where his father knew  Bin Laden, Abdullah Azzam, and Omar Abdel Rahman (the "Blind Sheikh"). 

Question: "Where did Mihdhar and Hazmi become experienced mujahideen?"

Answer: "Saudi"
Answer: no

Problem: (CNN) -- Tito Joseph "TJ" Jackson, who on Wednesday was named temporary guardian of Michael Jackson's three children, was inspired by his famous uncle to form a singing group with his brothers. TJ had been placed in charge of the children when the kids' grandmother, Katherine, left home on July 15 and will watch the children while the legal proceedings play out in a California court. TJ Jackson, 34, is the son of Tito Jackson and the late Delores Martes Jackson. TJ and his older brothers, Taj and Taryll, form the R&B group 3T. Jackson is married with three children, a boy and two girls. Judge suspends Katherine Jackson as guardian of Michael Jackson's children A 1995 article in People described the brothers' childhood as normal despite their famous father, uncle and aunts. Taj Jackson told the magazine: "My mom made sure that we had a real childhood, with birthday parties, baseball, family outings, all that stuff." They were close to their Uncle Michael. "He's like a third parent to us," Taj told People in 1995. Eventually the brothers went along on one of his tours and decided to form a singing group and were recording their first album in 1994 at the time of their mother's death. Initially it was believed Delores Martes Jackson, who had divorced from Tito Jackson in 1993, drowned in a swimming pool, but the case was reopened, and her sons in 1995 filed a wrongful-death lawsuit against a man they accused of killing her. Three years later, Donald Bohana was convicted of second-degree murder and sentenced to 15 years to life in prison, according to People magazine. 

Question: "How many children are in Tito's custody after this event?"

Answer: "3 children"
Answer: yes

Problem: 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 can density explain?"

Answer: "An objects mass and volume"
Answer:
yes
