Problem: Lancashire:

The county was established in 1182, later than many other counties. During Roman times the area was part of the Brigantes tribal area in the military zone of Roman Britain. The towns of Manchester, Lancaster, Ribchester, Burrow, Elslack and Castleshaw grew around Roman forts. In the centuries after the Roman withdrawal in 410AD the northern parts of the county probably formed part of the Brythonic kingdom of Rheged, a successor entity to the Brigantes tribe. During the mid-8th century, the area was incorporated into the Anglo-Saxon Kingdom of Northumbria, which became a part of England in the 10th century.

In what century were Roman forts first established?

Problem: Universal Studios:

In 2006, after almost 80 years, NBC Universal sold all Walt Disney-produced Oswald cartoons, along with the rights to the character himself, back to Disney.

Problem: Crimean War:

1855:Kars: In the year up to May 1855 Turkish forces in the east were reduced from 120,000 to 75,000, mostly by disease. The local Armenian population kept Muravyev well-informed about the Turks at Kars and he judged they had about five months of supplies. He therefore decided to control the surrounding area with cavalry and starve them out. He started in May and by June was south and west of the town. A relieving force fell back and there was a possibility of taking Erzerum, but Muravyev chose not to. In late September he learned of the fall of Sevastopol and a Turkish landing at Batum. This led him to reverse policy and try a direct attack. It failed, the Russians losing 8000 men and the Turks 1500 (29 September). The blockade continued and Kars surrendered on 8 November.

What caused the number of Turkish soldiers to decrease?
---
A: disease


Problem: Glacier:

Tidewater glaciers are glaciers that terminate in the sea, including most glaciers flowing from Greenland, Antarctica, Baffin and Ellesmere Islands in Canada, Southeast Alaska, and the Northern and Southern Patagonian Ice Fields. As the ice reaches the sea, pieces break off, or calve, forming icebergs. Most tidewater glaciers calve above sea level, which often results in a tremendous impact as the iceberg strikes the water. Tidewater glaciers undergo centuries-long cycles of advance and retreat that are much less affected by the climate change than those of other glaciers.

Hetero icebergs form glaciers?
