input: List of winners of the Boston Marathon

Many marathon champions have repeated their feats in following years. The record for most repeated championships stands at 10, held by Ernst van Dyk in the Men's Wheelchair division. In the Men's Open division, Clarence DeMar holds the distinction of most wins with seven, and Catherine Ndereba tops the Women's Open division with four. The United States has had more winners than any other country, followed by Kenya and Canada. The United States and Canada dominated the early years of the race, and it was not until the 36th race, in 1932, that someone from outside North America, Paul de Bruyn of Germany, won the race. During the period from World War II through the 1980s, there was much more national diversity among Boston Marathon champions, but the last two decades have seen Kenya emerge as the dominant nationality, especially in the Men's Open division, which (as of 2015) has been won by Kenyans in 19 of the past 25 years.

IN: Green is used as a backdrop for TV and electronic cinematography more than any other colour because television weathermen tended to wear blue suits. When chroma keying first came into use in television production, the blue screen that was then the norm in the movie industry was used out of habit, until other practical considerations caused the television industry to move from blue to green screens. Broadcast quality color television cameras use separate red, green and blue image sensors, and early analog TV chroma keyers required RGB component video to work reliably. From a technological perspective it was equally possible to use the blue or green channel, but because blue clothing was an ongoing challenge, the green screen came into common use. Newscasters sometimes forget the chroma key dress code, and when the key is applied to clothing of the same color as the background, the person would seem to disappear into the key. Because green clothing is less common than blue, it soon became apparent that it was easier to use a green matte screen than it was to constantly police the clothing choices of on-air talent. Also, because the human eye is more sensitive to green wavelengths, which lie in the middle of the visible light spectrum, the green analog video channel typically carried more signal strength, giving a better signal to noise ratio compared to the other component video channels, so green screen keys could produce the cleanest key. In the digital television and cinema age, much of the tweaking that was required to make a good quality key has been automated. However, the one constant that remains is some level of color coordination to keep foreground subjects from being keyed out.

Problem: Text: Despite the hype and commercial success, (Irish political figure Bertie Ahern's daughter) Cecilia Ahern's debut novel drew mixed-to-negative reception. Radio Telefis Eireann (RTE) gave it three out of five stars, stating that Ahern's book is ''funny and emotional'' but criticised his impression that the message of the book was one of getting over the death of a loved one by ''getting drunk and shopping''. The Guardian wrote a satirical review in which Ahern's shallow characterisation and melodramatic plot were lampooned. The Clare County library called the book ''overhyped'', ''predictable'' and ''full of stock characters'', but lastly an ''easy read... and a nice holiday read''. Amazon.co.uk calls it ''at times repetitive and her delivery is occasionally amateurish (but) Ahern deserves credit for a spirited first effort''.
