Problem: Extract the answer to the question from the following context. Question: How did Dutch evolve? Context: Three Germanic dialects were originally spoken in the Low Countries: Frisian in the north and along the western coast; Saxon in the east (contiguous with the Low German area); and Franconian in the centre and south. It is the Franconian dialects that is designated as Old Dutch, and that would develop in Middle Dutch and later Modern Dutch. The division in these development phases is mostly conventional, since the transition between them was very gradual. One of the few moments linguists can detect somewhat of a revolution is when the Dutch standard language emerged and quickly established itself. The development of the Dutch language is illustrated by the following sentence in Old, Middle and Modern Dutch:

A: Old Dutch, and that would develop in Middle Dutch and later Modern Dutch

Problem: Extract the answer to the question from the following context. Question: What happens when the irregularities of the surface are not much smaller than the wavelength? Context: The net quality of a ground reflection depends on the topography of the surface. When the irregularities of the surface are much smaller than the wavelength, we are in the regime of specular reflection, and the receiver sees both the real antenna and an image of the antenna under the ground due to reflection. But if the ground has irregularities not small compared to the wavelength, reflections will not be coherent but shifted by random phases. With shorter wavelengths (higher frequencies), this is generally the case.

A: reflections will not be coherent but shifted by random phases

Problem: Extract the answer to the question from the following context. Question: What is the name of the thing which people travel from Asian to America on? Context: Evidence suggests big-game hunter gatherers crossed the Bering Strait from Asia (Eurasia) into North America over a land bridge (Beringia), that existed between 47,00014,000 years ago. Around 18,500-15,500 years ago, these hunter-gatherers are believed to have followed herds of now-extinct Pleistocene megafauna along ice-free corridors that stretched between the Laurentide and Cordilleran ice sheets. Another route proposed is that, either on foot or using primitive boats, they migrated down the Pacific coast to South America.

A: Beringia

Problem: Extract the answer to the question from the following context. Question: The reservation established in 1888 is home to the? Context: Approximately 66,000 people of Native American heritage live in Montana. Stemming from multiple treaties and federal legislation, including the Indian Appropriations Act (1851), the Dawes Act (1887), and the Indian Reorganization Act (1934), seven Indian reservations, encompassing eleven tribal nations, were created in Montana. A twelfth nation, the Little Shell Chippewa is a "landless" people headquartered in Great Falls, recognized by the state of Montana but not by the U.S. Government. The Blackfeet nation is headquartered on the Blackfeet Indian Reservation (1851) in Browning, Crow on the Crow Indian Reservation (1851) in Crow Agency, Confederated Salish and Kootenai and Pend d'Oreille on the Flathead Indian Reservation (1855) in Pablo, Northern Cheyenne on the Northern Cheyenne Indian Reservation (1884) at Lame Deer, Assiniboine and Gros Ventre on the Fort Belknap Indian Reservation (1888) in Fort Belknap Agency, Assiniboine and Sioux on the Fort Peck Indian Reservation (1888) at Poplar, and Chippewa-Cree on the Rocky Boy's Indian Reservation (1916) near Box Elder. Approximately 63% of all Native people live off the reservations, concentrated in the larger Montana cities with the largest concentration of urban Indians in Great Falls. The state also has a small Metis population, and 1990 census data indicated that people from as many as 275 different tribes lived in Montana.

A:
Assiniboine and Gros Ventre
