One CATOBAR carrier: Sao Paulo is a Clemenceau-class aircraft carrier currently in service with the Brazilian Navy. Sao Paulo was first commissioned in 1963 by the French Navy as Foch and was transferred in 2000 to Brazil, where she became the new flagship of the Brazilian Navy. During the period from 20052010, Sao Paulo underwent extensive modernization. At the end of 2010, sea trials began, and as of 2011[update] Sao Paulo had been evaluated by the CIASA (Inspection Commission and Training Advisory). She was expected to rejoin the fleet in late 2013, but suffered another major fire in 2012.
What setback happened to Sao Paula in 2012?
****
The answer: another major fire

Protestantism has had an important influence on science. According to the Merton Thesis, there was a positive correlation between the rise of English Puritanism and German Pietism on the one hand and early experimental science on the other. The Merton Thesis has two separate parts: Firstly, it presents a theory that science changes due to an accumulation of observations and improvement in experimental technique and methodology; secondly, it puts forward the argument that the popularity of science in 17th-century England and the religious demography of the Royal Society (English scientists of that time were predominantly Puritans or other Protestants) can be explained by a correlation between Protestantism and the scientific values. Merton focused on English Puritanism and German Pietism as having been responsible for the development of the scientific revolution of the 17th and 18th centuries. He explained that the connection between religious affiliation and interest in science was the result of a significant synergy between the ascetic Protestant values and those of modern science. Protestant values encouraged scientific research by allowing science to identify God's influence on the worldhis creationand thus providing a religious justification for scientific research.
What other reason did Merton believe causes science to advance?
****
The answer: an accumulation of observations and improvement in experimental technique and methodology

The problem: Answer a question about this article:
Some paleontologists suggest that animals appeared much earlier than the Cambrian explosion, possibly as early as 1 billion years ago. Trace fossils such as tracks and burrows found in the Tonian period indicate the presence of triploblastic worms, like metazoans, roughly as large (about 5 mm wide) and complex as earthworms. During the beginning of the Tonian period around 1 billion years ago, there was a decrease in Stromatolite diversity, which may indicate the appearance of grazing animals, since stromatolite diversity increased when grazing animals went extinct at the End Permian and End Ordovician extinction events, and decreased shortly after the grazer populations recovered. However the discovery that tracks very similar to these early trace fossils are produced today by the giant single-celled protist Gromia sphaerica casts doubt on their interpretation as evidence of early animal evolution.
Fossils found in the Tonian period indicate the presence of what creatures?
****
The answer: triploblastic worms

Ottoman classical music was an important part of the education of the Ottoman elite, a number of the Ottoman sultans were accomplished musicians and composers themselves, such as Selim III, whose compositions are often still performed today. Ottoman classical music arose largely from a confluence of Byzantine music, Armenian music, Arabic music, and Persian music. Compositionally, it is organised around rhythmic units called usul, which are somewhat similar to meter in Western music, and melodic units called makam, which bear some resemblance to Western musical modes.
What rhythmic units does Ottoman classical music use?
****
The answer:
units called usul
