In Australia, Presbyterianism is the fourth largest denomination of Christianity, with nearly 600,000 Australians claiming to be Presbyterian in the 2006 Commonwealth Census. Presbyterian churches were founded in each colony, some with links to the Church of Scotland and others to the Free Church. There were also congregations originating from United Presbyterian Church of Scotland as well as a number founded by John Dunmore Lang. Most of these bodies merged between 1859 and 1870, and in 1901 formed a federal union called the Presbyterian Church of Australia but retaining their state assemblies. The Presbyterian Church of Eastern Australia representing the Free Church of Scotland tradition, and congregations in Victoria of the Reformed Presbyterian Church, originally from Ireland, are the other existing denominations dating from colonial times.
According to the 1901 census, how many Australians claim to be Presbyterian?
A: unanswerable

In June 2006, Steven Spielberg announced he would direct a scientifically accurate film about "a group of explorers who travel through a worm hole and into another dimension", from a treatment by Kip Thorne and producer Lynda Obst. In January 2007, screenwriter Jonathan Nolan met with them to discuss adapting Obst and Thorne's treatment into a narrative screenplay. The screenwriter suggested the addition of a "time element" to the treatment's basic idea, which was welcomed by Obst and Thorne. In March of that year, Paramount hired Nolan, as well as scientists from Caltech, forming a workshop to adapt the treatment under the title Interstellar. The following July, Kip Thorne said there was a push by people for him to portray himself in the film. Spielberg later abandoned Interstellar, which was eventually directed by Christopher Nolan.
In what year did Christopher Nolan become a director?
A: unanswerable

The single most revealing property of wood as an indicator of wood quality is specific gravity (Timell 1986), as both pulp yield and lumber strength are determined by it. Specific gravity is the ratio of the mass of a substance to the mass of an equal volume of water; density is the ratio of a mass of a quantity of a substance to the volume of that quantity and is expressed in mass per unit substance, e.g., grams per millilitre (g/cm3 or g/ml). The terms are essentially equivalent as long as the metric system is used. Upon drying, wood shrinks and its density increases. Minimum values are associated with green (water-saturated) wood and are referred to as basic specific gravity (Timell 1986).
Which property of wood reveals the most about its quality?
A: specific gravity

The roots of Presbyterianism lie in the European Reformation of the 16th century; the example of John Calvin's Geneva being particularly influential. Most Reformed churches which trace their history back to Scotland are either presbyterian or congregationalist in government. In the twentieth century, some Presbyterians played an important role in the ecumenical movement, including the World Council of Churches. Many Presbyterian denominations have found ways of working together with other Reformed denominations and Christians of other traditions, especially in the World Communion of Reformed Churches. Some Presbyterian churches have entered into unions with other churches, such as Congregationalists, Lutherans, Anglicans, and Methodists. Presbyterians in the United States came largely from Scotch-Irish immigrants communities, and also from New England Yankee communities that had originally been Congregational but changed because of an agreed-upon "Plan of Union of 1801" for frontier areas.
Where do most presbyterian churches trace their history back to?
A:
Scotland
