Problem: Geological history of Earth:

The northern supercontinent of Laurasia began to break up, as Europe, Greenland and North America drifted apart. In western North America, mountain building started in the Eocene, and huge lakes formed in the high flat basins among uplifts. In Europe, the Tethys Sea finally vanished, while the uplift of the Alps isolated its final remnant, the Mediterranean, and created another shallow sea with island archipelagos to the north. Though the North Atlantic was opening, a land connection appears to have remained between North America and Europe since the faunas of the two regions are very similar. India continued its journey away from Africa and began its collision with Asia, creating the Himalayan orogeny.

What sea opened up?

A: unanswerable

Problem: Diarrhea:

WHO recommends a child with diarrhea continue to be fed. Continued feeding speeds the recovery of normal intestinal function. In contrast, children whose food is restricted have diarrhea of longer duration and recover intestinal function more slowly. A child should also continue to be breastfed. The WHO states "Food should never be withheld and the child's usual foods should not be diluted. Breastfeeding should always be continued." And in the specific example of cholera, CDC also makes the same recommendation. In young children who are not breast-fed and live in the developed world, a lactose-free diet may be useful to speed recovery.

What happens when a childs food is restricted?
---
A: children whose food is restricted have diarrhea of longer duration and recover intestinal function more slowly

Problem: Pub:

A number of pubs claim to be the oldest surviving establishment in the United Kingdom, although in several cases original buildings have been demolished and replaced on the same site. Others are ancient buildings that saw uses other than as a pub during their history. Ye Olde Fighting Cocks in St Albans, Hertfordshire, holds the Guinness World Record for the oldest pub in England, as it is an 11th-century structure on an 8th-century site. Ye Olde Trip to Jerusalem in Nottingham is claimed to be the "oldest inn in England". It has a claimed date of 1189, based on the fact it is constructed on the site of the Nottingham Castle brewhouse; the present building dates from around 1650. Likewise, The Nags Head in Burntwood, Staffordshire only dates back to the 16th century, but there has been a pub on the site since at least 1086, as it is mentioned in the Domesday Book.

When does Ye Olde Trip to Jerusalem claim to have been founded?
---
A: 1189

Problem: British Isles:

The Northern Ireland Peace Process has led to a number of unusual arrangements between the Republic of Ireland, Northern Ireland and the United Kingdom. For example, citizens of Northern Ireland are entitled to the choice of Irish or British citizenship or both and the Governments of Ireland and the United Kingdom consult on matters not devolved to the Northern Ireland Executive. The Northern Ireland Executive and the Government of Ireland also meet as the North/South Ministerial Council to develop policies common across the island of Ireland. These arrangements were made following the 1998 Good Friday Agreement.

What has caused several uncommon arrangements between the various states in the United Kingdom?
