Problem: Presbyterianism:

In 1977, two thirds of the Presbyterian Church of Australia, along with most of the Congregational Union of Australia and all the Methodist Church of Australasia, combined to form the Uniting Church in Australia. The third who did not unite had various reasons for so acting, often cultural attachment but often conservative theological or social views. The permission for the ordination of women given in 1974 was rescinded in 1991 without affecting the two or three existing woman ministers. The approval of women elders given in the 1960s has been rescinded in all states except New South Wales, which has the largest membership. The theology of the church is now generally conservative and Reformed. A number of small Presbyterian denominations have arisen since the 1950s through migration or schism.

Which state, the only to not have rescinded approval of women elders, has the smallest membership?

Problem: Wood:

Wood has a long history of being used as fuel, which continues to this day, mostly in rural areas of the world. Hardwood is preferred over softwood because it creates less smoke and burns longer. Adding a woodstove or fireplace to a home is often felt to add ambiance and warmth.

What benefit besides the cozy atmosphere would a wood-burning fireplace add to a home?

A: warmth


Problem: Aircraft carrier:

The 1903 advent of heavier-than-air fixed-wing aircraft was closely followed in 1910 by the first experimental take-off of an airplane, made from the deck of a United States Navy vessel (cruiser USS Birmingham), and the first experimental landings were conducted in 1911. On 9 May 1912 the first airplane take-off from a ship underway was made from the deck of the British Royal Navy's HMS Hibernia. Seaplane tender support ships came next, with the French Foudre of 1911. In September 1914 the Imperial Japanese Navy Wakamiya conducted the world's first successful ship-launched air raid: on 6 September 1914 a Farman aircraft launched by Wakamiya attacked the Austro-Hungarian cruiser SMS Kaiserin Elisabeth and the German gunboat Jaguar in Kiaochow Bay off Tsingtao; neither was hit. The first carrier-launched airstrike was the Tondern Raid in July 1918. Seven Sopwith Camels launched from the converted battlecruiser HMS Furious damaged the German airbase at Tønder and destroyed two zeppelins.

In what year was the advent of lighter-than-air fixed-wing aircraft?

A: unanswerable


Problem: Quran:

A text is self-referential when it speaks about itself and makes reference to itself. According to Stefan Wild, the Quran demonstrates this metatextuality by explaining, classifying, interpreting and justifying the words to be transmitted. Self-referentiality is evident in those passages where the Quran refers to itself as revelation (tanzil), remembrance (dhikr), news (naba'), criterion (furqan) in a self-designating manner (explicitly asserting its Divinity, "And this is a blessed Remembrance that We have sent down; so are you now denying it?"), or in the frequent appearance of the "Say" tags, when Muhammad is commanded to speak (e.g., "Say: 'God's guidance is the true guidance' ", "Say: 'Would you then dispute with us concerning God?' "). According to Wild the Quran is highly self-referential. The feature is more evident in early Meccan suras.

What quality doesn't the Quran claim in the different ways in which it refers to itself?
