Article: Internationally, Victoria took a keen interest in the improvement of relations between France and Britain. She made and hosted several visits between the British royal family and the House of Orleans, who were related by marriage through the Coburgs. In 1843 and 1845, she and Albert stayed with King Louis Philippe I at chateau d'Eu in Normandy; she was the first British or English monarch to visit a French one since the meeting of Henry VIII of England and Francis I of France on the Field of the Cloth of Gold in 1520. When Louis Philippe made a reciprocal trip in 1844, he became the first French king to visit a British sovereign. Louis Philippe was deposed in the revolutions of 1848, and fled to exile in England. At the height of a revolutionary scare in the United Kingdom in April 1848, Victoria and her family left London for the greater safety of Osborne House, a private estate on the Isle of Wight that they had purchased in 1845 and redeveloped. Demonstrations by Chartists and Irish nationalists failed to attract widespread support, and the scare died down without any major disturbances. Victoria's first visit to Ireland in 1849 was a public relations success, but it had no lasting impact or effect on the growth of Irish nationalism.

Question: What year was Victorias first visit to Ireland?
Ans: 1849

Here is a question about this article: Green can communicate safety to proceed, as in traffic lights. Green and red were standardized as the colors of international railroad signals in the 19th century. The first traffic light, using green and red gas lamps, was erected in 1868 in front of the Houses of Parliament in London. It exploded the following year, injuring the policeman who operated it. In 1912, the first modern electric traffic lights were put up in Salt Lake City, Utah. Red was chosen largely because of its high visibility, and its association with danger, while green was chosen largely because it could not be mistaken for red. Today green lights universally signal that a system is turned on and working as it should. In many video games, green signifies both health and completed objectives, opposite red.
What is the answer to this question: Besides its association with danger, why was red chosen for traffic lights?
****
So... high visibility
