question:
Rock layers extend laterally, or out to the sides. They may cover very large areas. This is especially true if they formed at the bottom of ancient seas. Seas are very large areas of water. Over time, sediment builds up on the seabed. They will be covered with the same types of material. As rocks form out of this sediment it will all be the same type. The rocks may be forced up above the water as Earths plates move. Rivers may eventually run across this area. The river will cut into the rock and erode it away. The layers of exposed rock on either side of the river will still match up. Look at the Grand Canyon in Figure 2.27. Its a good example of lateral continuity. You can clearly see the same rock layers on opposite sides of the canyon. The matching rock layers were deposited at the same time. They are the same age. <sep>What is the Grand Canyon a good example of?<sep>lateral continuity
answer:
Yes


question:
In 1863, Alexander II re-convened the Diet of Finland and initiated several reforms increasing Finland's autonomy from Russia including establishment of its own currency, the markka. Liberation of business led to increased foreign investment and industrial development. Finland also got its first railways, separately established under Finnish administration. Finally, the elevation of Finnish from a language of the common people to a national language equal to Swedish opened opportunities for a larger proportion of the society. Alexander II is still regarded as "The Good Tsar" in Finland. These reforms could be seen as results of a genuine belief that reforms were easier to test in an underpopulated, homogeneous country, than in the whole of Russia. They may also be seen as a reward for the loyalty of its relatively western-oriented population during the Crimean War and during the Polish uprising. Encouraging Finnish nationalism and language can also be seen as an attempt to dilute ties with Sweden. <sep>What were the results for Finland establishing its own language?<sep>Establishment of its own currency, the markka
answer:
No


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. <sep>What was the weather like when President George W. Bush went for his early morning run?<sep>Good weather conditions in the eastern United States
answer:

Yes
