Question:
Tuesday, September 11, 2001, dawned temperate and nearly cloudless in the eastern United States. Millions of men and women readied themselves for work. Some made their way to the Twin Towers, the signature structures of the World Trade Center complex in New York City. Others went to Arlington, Virginia, to the Pentagon. Across the Potomac River, the United States Congress was back in session. At the other end of Pennsylvania Avenue, people began to line up for a White House tour. In Sarasota, Florida, President George W. Bush went for an early morning run. For those heading to an airport, weather conditions could not have been better for a safe and pleasant journey. Among the travelers were Mohamed Atta and Abdul Aziz al Omari, who arrived at the airport in Portland, Maine. Boston: American 11 and United 175. Atta and Omari boarded a 6:00 A.M. flight from Portland to Boston's Logan International Airport. When he checked in for his flight to Boston, Atta was selected by a computerized prescreening system known as CAPPS (Computer Assisted Passenger Prescreening System), created to identify passengers who should be subject to special security measures. Under security rules in place at the time, the only consequence of Atta's selection by CAPPS was that his checked bags were held off the plane until it was confirmed that he had boarded the aircraft. This did not hinder Atta's plans. Atta and Omari arrived in Boston at 6:45. Seven minutes later, Atta apparently took a call from Marwan al Shehhi, a longtime colleague who was at another terminal at Logan Airport. They spoke for three minutes. It would be their final conversation. After reading the above, is "Three quarters of an hour" the correct answer to the question "From the time Atta and Omari boarded their flight in Portland, how long did it take them to reach Boston"? OPTIONS:
- no
- yes

Answer:
yes

Input: Alexander II's death caused a great setback for the reform movement. One of his last ideas was to draft plans for an elected parliament, or Duma, which were completed the day before he died but not yet released to the Russian people. In a matter of 48 hours, Alexander II planned to release his plan for the duma to the Russian people. Had he lived, Russia might have followed a path to constitutional monarchy instead of the long road of oppression that defined his successor's reign. The first action Alexander III took after his father's death was to tear up those plans. A Duma would not come into fruition until 1905, when Alexander II's grandson, Nicholas II, commissioned the Duma following extreme pressure on the monarchy as a result of the Russian Revolution of 1905. The assassination triggered major suppression of civil liberties in Russia, and police brutality burst back in full force after experiencing some restraint under the reign of Alexander II, whose death was witnessed first-hand by his son, Alexander III, and his grandson, Nicholas II, both future emperors who vowed not to have the same fate befall them. Both of them used the Okhrana to arrest protestors and uproot suspected rebel groups, creating further suppression of personal freedom for the Russian people. A series of anti-Jewish pogroms and antisemitic legislation, the May Laws, were yet another result. Finally, the tsar's assassination also inspired anarchists to advocate "'propaganda by deed'--the use of a spectacular act of violence to incite revolution." With construction starting in 1883, the Church of the Savior on Blood was built on the site of Alexander's assassination and dedicated in his memory.
"What effect did Alexander II's death have on the Russian political climate?" is "It prompted the end of the anarchist movement"?

Input: The properties of matter depend on the types of atoms that matter is made of. Matter can exist in two forms. It can be a pure substance. This means it is not mixed with anything. It can also be a combination of different substances. This means it can be a mix of different types of atoms. You may recall that atoms differ based on the numbers of protons they contain. Some atoms contain only one proton such as Hydrogen. Other atoms contain many protons. There are many types of atoms. For example, Helium has two protons. An Oxygen atom has eight. Water is composed of a two types of atoms. Water is made of two Hydrogen atoms and one Oxygen atoms. There are only so many types of atoms. These atoms can be mixed into an almost limitless amount of substances. So what do we call a substance that has only a single type of atom?

Does the response "Hydrogen" correctly answer the question "What atoms is water composed of?"?

OPTIONS:
- no
- yes

Output: yes

Question:
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. After reading the above, is "Nashiri managed the operation in Yemen" the correct answer to the question "What roles did Bin Laden, Khallad, and Nashiri have in al Qaeda?"? OPTIONS:
- no
- yes

Answer:
yes
