Problem: Nintendo Entertainment System:

In 1986, Nintendo released the Famicom Disk System (FDS) in Japan, a type of floppy drive that uses a single-sided, proprietary 5 cm (2") disk and plugs into the cartridge port. It contains RAM for the game to load into and an extra single-cycle wavetable-lookup sound chip. The disks were originally obtained from kiosks in malls and other public places where buyers could select a title and have it written to the disk. This process would cost less than cartridges and users could take the disk back to a vending booth and have it rewritten with a new game. The disks were used both for storing the game and saving progress and total capacity was 128k (64k per side).

What were the storage disks used for?
---
A: storing the game and saving progress


Problem: A cappella:

Present-day Christian religious bodies known for conducting their worship services without musical accompaniment include some Presbyterian churches devoted to the regulative principle of worship, Old Regular Baptists, Primitive Baptists, Plymouth Brethren, Churches of Christ, the Old German Baptist Brethren, Doukhobors the Byzantine Rite and the Amish, Old Order Mennonites and Conservative Mennonites. Certain high church services and other musical events in liturgical churches (such as the Roman Catholic Mass and the Lutheran Divine Service) may be a cappella, a practice remaining from apostolic times. Many Mennonites also conduct some or all of their services without instruments. Sacred Harp, a type of folk music, is an a cappella style of religious singing with shape notes, usually sung at singing conventions.

In present times, which group is know to use shape notes in religious services?
---
A: unanswerable


Problem: Bird migration:

Theoretical analyses show that detours that increase flight distance by up to 20% will often be adaptive on aerodynamic grounds - a bird that loads itself with food to cross a long barrier flies less efficiently. However some species show circuitous migratory routes that reflect historical range expansions and are far from optimal in ecological terms. An example is the migration of continental populations of Swainson's thrush Catharus ustulatus, which fly far east across North America before turning south via Florida to reach northern South America; this route is believed to be the consequence of a range expansion that occurred about 10,000 years ago. Detours may also be caused by differential wind conditions, predation risk, or other factors.

Where do Swainson's thrush fly from?
---
A: far east across North America


Problem: British Isles:

By the Late Middle Ages, Great Britain was separated into the Kingdoms of England and Scotland. Power in Ireland fluxed between Gaelic kingdoms, Hiberno-Norman lords and the English-dominated Lordship of Ireland. A similar situation existed in the Principality of Wales, which was slowly being annexed into the Kingdom of England by a series of laws. During the course of the 15th century, the Crown of England would assert a claim to the Crown of France, thereby also releasing the King of England as from being vassal of the King of France. In 1534, King Henry VIII, at first having been a strong defender of Roman Catholicism in the face of the Reformation, separated from the Roman Church after failing to secure a divorce from the Pope. His response was to place the King of England as "the only Supreme Head in Earth of the Church of England", thereby removing the authority of the Pope from the affairs of the English Church. Ireland, which had been held by the King of England as Lord of Ireland, but which strictly speaking had been a feudal possession of the Pope since the Norman invasion was declared a separate kingdom in personal union with England.

Since the Norman invasion who had feudal possession of Ireland?
---
A:
the Pope
