Article: Some scientific studies suggest that ozone depletion may have a dominant role in governing climatic change in Antarctica (and a wider area of the Southern Hemisphere). Ozone absorbs large amounts of ultraviolet radiation in the stratosphere. Ozone depletion over Antarctica can cause a cooling of around 6 C in the local stratosphere. This cooling has the effect of intensifying the westerly winds which flow around the continent (the polar vortex) and thus prevents outflow of the cold air near the South Pole. As a result, the continental mass of the East Antarctic ice sheet is held at lower temperatures, and the peripheral areas of Antarctica, especially the Antarctic Peninsula, are subject to higher temperatures, which promote accelerated melting. Models also suggest that the ozone depletion/enhanced polar vortex effect also accounts for the recent increase in sea ice just offshore of the continent.

Question: In what do some scientists believe ozone depletion may have a role ?
Ans: climatic change

Article: Filming temporarily returned to England to shoot scenes at Blenheim Palace in Oxfordshire, which stood in for a location in Rome, before moving on to the city itself for a five-week shoot across the city, with locations including the Ponte Sisto bridge and the Roman Forum. The production faced opposition from a variety of special interest groups and city authorities, who were concerned about the potential for damage to historical sites around the city, and problems with graffiti and rubbish appearing in the film. A car chase scene set along the banks of the Tiber River and through the streets of Rome featured an Aston Martin DB10 and a Jaguar C-X75. The C-X75 was originally developed as a hybrid electric vehicle with four independent electric engines powered by two jet turbines, before the project was cancelled. The version used for filming was converted to use a conventional internal combustion engine, to minimise the potential for disruption from mechanical problems with the complex hybrid system. The C-X75s used for filming were developed by the engineering division of Formula One racing team Williams, who built the original C-X75 prototype for Jaguar.

Question: For which auto maker did Williams first develop the C-X75?
Ans: Jaguar

Article: In 1853 the Russian Empire on behalf of the Slavic Balkan states began to question the very existence of the Ottoman Empire. The result was the Crimean War, 18531856, in which the British Empire and the French Empire supported the Ottoman Empire in its struggle against the incursions of the Russian Empire. Eventually, the Ottoman Empire lost control of the Balkan region.

Question: When was the Crimean War?
Ans: 18531856

Article: The Juscelino Kubitschek bridge, also known as the 'President JK Bridge' or the 'JK Bridge', crosses Lake Paranoa in Brasilia. It is named after Juscelino Kubitschek de Oliveira, former president of Brazil. It was designed by architect Alexandre Chan and structural engineer Mario Vila Verde. Chan won the Gustav Lindenthal Medal for this project at the 2003 International Bridge Conference in Pittsburgh due to "...outstanding achievement demonstrating harmony with the environment, aesthetic merit and successful community participation".

Question: Who was de Oliveira?
Ans:
former president of Brazil
