Problem: Micronesian colonists gradually settled the Marshall Islands during the 2nd millennium BC, with inter-island navigation made possible using traditional stick charts. Islands in the archipelago were first explored by Europeans in the 1520s, with Spanish explorer Alonso de Salazar sighting an atoll in August 1526. Other expeditions by Spanish and English ships followed. The islands derive their name from British explorer John Marshall, who visited in 1788. The islands were historically known by the inhabitants as "jolet jen Anij" (Gifts from God).
For whom are the Marshall Islands named?
The answer is the following: John Marshall

Problem: In the 1990s, Dell switched from using primarily ATX motherboards and PSU to using boards and power supplies with mechanically identical but differently wired connectors. This meant customers wishing to upgrade their hardware would have to replace parts with scarce Dell-compatible parts instead of commonly available parts. While motherboard power connections reverted to the industry standard in 2003, Dell continues to remain secretive about their motherboard pin-outs for peripherals (such as MMC readers and power on/off switches and LEDs).
What part of their motherboards does Dell not reveal the specifications of?
The answer is the following: pin-outs

Problem: John remained Lord of Ireland throughout his reign. He drew on the country for resources to fight his war with Philip on the continent. Conflict continued in Ireland between the Anglo-Norman settlers and the indigenous Irish chieftains, with John manipulating both groups to expand his wealth and power in the country. During Richard's rule, John had successfully increased the size of his lands in Ireland, and he continued this policy as king. In 1210 the king crossed into Ireland with a large army to crush a rebellion by the Anglo-Norman lords; he reasserted his control of the country and used a new charter to order compliance with English laws and customs in Ireland. John stopped short of trying to actively enforce this charter on the native Irish kingdoms, but historian David Carpenter suspects that he might have done so, had the baronial conflict in England not intervened. Simmering tensions remained with the native Irish leaders even after John left for England.
John remained what throughout his reign?
The answer is the following: Lord of Ireland

Problem: St Helena's biodiversity, however, also includes marine vertebrates, invertebrates (freshwater, terrestrial and marine), fungi (including lichen-forming species), non-vascular plants, seaweeds and other biological groups. To date, very little is known about these, although more than 200 lichen-forming fungi have been recorded, including 9 endemics, suggesting that many significant discoveries remain to be made.
How many endemic species of fungi have been found?
The answer is the following:
9
