[Q]: Passage: The Crag Group is a geological group outcropping in East Anglia, UK and adjacent areas of the North Sea. Its age ranges from approximately 4.4 to 0.478 million years BP, spanning the late Pliocene and early to middle Pleistocene epochs. It comprises a range of marine and estuarine sands, gravels, silts and clays deposited in a relatively shallow-water, tidally-dominated marine embayment on the western margins of the North Sea basin. The sands are characteristically dark green from glauconite but weather bright orange, with haematite 'iron pans' forming. The lithology of the lower part of the Group is almost entirely flint. The highest formation in the Group, the Wroxham Crag, contains over 10% of far-travelled lithologies, notably quartzite and vein quartz from the Midlands, igneous rocks from Wales, and chert from the Upper Greensand of southeastern England. This exotic rock component was introduced by rivers such as the Bytham River and Proto-Thames. 
 Link Information: The North Sea is a marginal sea of the Atlantic Ocean located between Great Britain (particularly England and Scotland), Denmark, Norway, Germany, the Netherlands, Belgium and France. An epeiric (or "shelf") sea on the European continental shelf, it connects to the ocean through the English Channel in the south and the Norwegian Sea in the north. It is more than 970 km long and 580 km wide, with an area of 570000 km2 Question: What is the area in meters of the sea that is adjacent to the Crag Group?
[A]: Answer: 570000


[Q]: Passage: During the Russian Revolution of 1905, conflict erupted between the Armenians and the Azeris, culminating in the Armenian-Tatar massacres. In the final year of World War I, Nakhchivan was the scene of more bloodshed between Armenians and Azerbaijanis, who both laid claim to the area. By 1914, the Armenian population was at 40% while the Azeri population increased to roughly 60%. After the February Revolution, the region was under the authority of the Special Transcaucasian Committee of the Russian Provisional Government and subsequently of the short-lived Transcaucasian Democratic Federative Republic. When the TDFR was dissolved in May 1918, Nakhchivan, Nagorno-Karabakh, Zangezur (today the Armenian province of Syunik), and Qazakh were heavily contested between the newly formed and short-lived states of the First Republic of Armenia and the Azerbaijan Democratic Republic (ADR). In June 1918, the region came under Ottoman occupation. Under the terms of the Armistice of Mudros, the Ottomans agreed to pull their troops out of the Transcaucasus to make way for the forthcoming British military presence.
 Link Information: he massacres started during the Russian Revolution of 1905, and claimed hundreds of lives.  Question: Approximately how many people died in the massacares at the end of the Russian Revolution?
[A]: Answer: hundreds


[Q]: Passage: The Bad Pass Trail, also known as the Sioux Trail, was established by Native Americans on the border of present-day Montana and Wyoming as a means of access from the Bighorn Basin in Wyoming to Bison-hunting grounds in the Grapevine Creek area of Montana. Marked by stone cairns, the trail led across Bad Pass and was established in pre-Columbian times. After Europeans arrived in the area it was frequented by fur trappers and mountain men, beginning in 1824. Trappers assembled pack trains at the junction of the Shoshone River and the Bighorn River, using the Bad Pass Trail to avoid Bighorn Canyon. The trail ended at the mouth of Grapevine Creek on the Bighorn, from which the pack train could float down the Bighorn on rafts to the Yellowstone River and then to the Missouri and on to St. Louis.
 Link Information: The Shoshone River is a 100 mi long river in northern Wyoming Question: Which river that trappers assembled pack trains at the junction of is longer?
[A]:
Answer: The Bighorn River
