Problem: Switzerland:

Skiing, snowboarding and mountaineering are among the most popular sports in Switzerland, the nature of the country being particularly suited for such activities. Winter sports are practiced by the natives and tourists since the second half of the 19th century with the invention of bobsleigh in St. Moritz. The first world ski championships were held in Murren (1931) and St. Moritz (1934). The latter town hosted the second Winter Olympic Games in 1928 and the fifth edition in 1948. Among the most successful skiers and world champions are Pirmin Zurbriggen and Didier Cuche.

Where was the bobsleigh invented?

A: St. Moritz

Problem: East Prussia:

The population of the province in 1900 was 1,996,626 people, with a religious makeup of 1,698,465 Protestants, 269,196 Roman Catholics, and 13,877 Jews. The Low Prussian dialect predominated in East Prussia, although High Prussian was spoken in Warmia. The numbers of Masurians, Kursenieki and Prussian Lithuanians decreased over time due to the process of Germanization. The Polish-speaking population concentrated in the south of the province (Masuria and Warmia) and all German geographic atlases at the start of 20th century showed the southern part of East Prussia as Polish with the number of Poles estimated at the time to be 300,000. Kursenieki inhabited the areas around the Curonian lagoon, while Lithuanian-speaking Prussians concentrated in the northeast in (Lithuania Minor). The Old Prussian ethnic group became completely Germanized over time and the Old Prussian language died out in the 18th century.

What religion were the Kursenieki?

A: unanswerable

Problem: Bird migration:

Birds fly at varying altitudes during migration. An expedition to Mt. Everest found skeletons of northern pintail Anas acuta and black-tailed godwit Limosa limosa at 5,000 m (16,000 ft) on the Khumbu Glacier. Bar-headed geese Anser indicus have been recorded by GPS flying at up to 6,540 metres (21,460 ft) while crossing the Himalayas, at the same time engaging in the highest rates of climb to altitude for any bird. Anecdotal reports of them flying much higher have yet to be corroborated with any direct evidence. Seabirds fly low over water but gain altitude when crossing land, and the reverse pattern is seen in landbirds. However most bird migration is in the range of 150 to 600 m (490 to 1,970 ft). Bird strike aviation records from the United States show most collisions occur below 600 m (2,000 ft) and almost none above 1,800 m (5,900 ft).

Where do most in air collisions occur?
---
A:
below 600 m
