Article: 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.

Question: Where do most presbyterian churches trace their history back to?
Ans: Scotland


Here is a question about this article: Unlike the Baroque style that it replaced, which was mostly used for palaces and churches, and had little representation in the British colonies, simpler Georgian styles were widely used by the upper and middle classes. Perhaps the best remaining house is the pristine Hammond-Harwood House (1774) in Annapolis, Maryland, designed by the colonial architect William Buckland and modelled on the Villa Pisani at Montagnana, Italy as depicted in Andrea Palladio's I quattro libri dell'architettura ("Four Books of Architecture").
What is the answer to this question: What building did William Buckland model the Hammon-Harwood House?
****
So... Villa Pisani at Montagnana, Italy


The problem: Answer a question about this article:
Portugal has arguably the most liberal laws concerning possession of illicit drugs in the Western world. In 2001, Portugal decriminalized possession of effectively all drugs that are still illegal in other developed nations including, but not limited to, cannabis, cocaine, heroin, and LSD. While possession is legal, trafficking and possession of more than "10 days worth of personal use" are still punishable by jail time and fines. People caught with small amounts of any drug are given the choice to go to a rehab facility, and may refuse treatment without consequences. Despite criticism from other European nations, who stated Portugal's drug consumption would tremendously increase, overall drug use has declined along with the number of HIV infection cases, which had dropped 50 percent by 2009. Drug use among 16- to 18-year-olds also declined, however the use of marijuana rose only slightly among that age group.
By 2009, by how much had the rate of HIV infection decreased?
****
The answer: 50 percent


Problem: Please answer a question about the following article about Serbo-Croatian:
South Slavic historically formed a dialect continuum, i.e. each dialect has some similarities with the neighboring one, and differences grow with distance. However, migrations from the 16th to 18th centuries resulting from the spread of Ottoman Empire on the Balkans have caused large-scale population displacement that broke the dialect continuum into many geographical pockets. Migrations in the 20th century, primarily caused by urbanization and wars, also contributed to the reduction of dialectal differences.
What caused the dialect continuum to become fractured?
A: migrations from the 16th to 18th centuries resulting from the spread of Ottoman Empire on the Balkans

The insect outer skeleton, the cuticle, is made up of two layers: the epicuticle, which is a thin and waxy water resistant outer layer and contains no chitin, and a lower layer called the procuticle. The procuticle is chitinous and much thicker than the epicuticle and has two layers: an outer layer known as the exocuticle and an inner layer known as the endocuticle. The tough and flexible endocuticle is built from numerous layers of fibrous chitin and proteins, criss-crossing each other in a sandwich pattern, while the exocuticle is rigid and hardened.:22–24 The exocuticle is greatly reduced in many soft-bodied insects (e.g., caterpillars), especially during their larval stages.
The cuticle has how many layers?
two
