The hijackers attacked at 9:28. While traveling 35,000 feet above eastern Ohio, United 93 suddenly dropped 700 feet. Eleven seconds into the descent, the FAA's air traffic control center in Cleveland received the first of two radio transmissions from the aircraft. During the first broadcast, the captain or first officer could be heard declaring "Mayday" amid the sounds of a physical struggle in the cockpit. The second radio transmission, 35 seconds later, indicated that the fight was continuing. The captain or first officer could be heard shouting:" Hey get out of here-get out of here-get out of here." On the morning of 9/11, there were only 37 passengers on United 93-33 in addition to the 4 hijackers. This was below the norm for Tuesday mornings during the summer of 2001. But there is no evidence that the hijackers manipulated passenger levels or purchased additional seats to facilitate their operation. The terrorists who hijacked three other commercial flights on 9/11 operated in five-man teams. They initiated their cockpit takeover within 30 minutes of takeoff. On Flight 93, however, the takeover took place 46 minutes after takeoff and there were only four hijackers. The operative likely intended to round out the team for this flight, Mohamed al Kahtani, had been refused entry by a suspicious immigration inspector at Florida's Orlando International Airport in August. Because several passengers on United 93 described three hijackers on the plane, not four, some have wondered whether one of the hijackers had been able to use the cockpit jump seat from the outset of the flight. FAA rules allow use of this seat by documented and approved individuals, usually air carrier or FAA personnel. We have found no evidence indicating that one of the hijackers, or anyone else, sat there on this flight. All the hijackers had assigned seats in first class, and they seem to have used them. We believe it is more likely that Jarrah, the crucial pilot-trained member of their team, remained seated and inconspicuous until after the cockpit was seized; and once inside, he would not have been visible to the passengers.

Question: "Jarrah remained seated where during the takeover?"

Response: "the cockpit"

A: no

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 is density?"

Response: "The conductivity of an object"

A: no

Meridian National Corp. said it sold 750,000 shares of its common stock to the McAlpine family interests, for $1 million, or $1.35 a share. The sale represents 10.2% of Meridian's shares outstanding. The McAlpine family, which operates a number of multinational companies, including a London-based engineering and construction company, also lent to Meridian National $500,000. That amount is convertible into shares of Meridian common stock at $2 a share during its one-year term. The loan may be extended by the McAlpine group for an additional year with an increase in the conversion price to $2.50 a share. The sale of shares to the McAlpine family along with the recent sale of 750,000 shares of Meridian stock to Haden MacLellan Holding PLC of Surrey, England and a recent public offering have increased Meridian's net worth to $8.5 million, said William Feniger, chief executive officer of Toledo, Ohio-based Meridian.

Question: "To whom did Meridian sell 10.2% of its shares?"
