Problem: Melbourne:

Melbourne has a temperate oceanic climate (Koppen climate classification Cfb) and is well known for its changeable weather conditions. This is mainly due to Melbourne's location situated on the boundary of the very hot inland areas and the cool southern ocean. This temperature differential is most pronounced in the spring and summer months and can cause very strong cold fronts to form. These cold fronts can be responsible for all sorts of severe weather from gales to severe thunderstorms and hail, large temperature drops, and heavy rain.

What is Melbourne's Koppen climate classification?

A: Cfb

Problem: For much of Arsenal's history, their home colours have been bright red shirts with white sleeves and white shorts, though this has not always been the case. The choice of red is in recognition of a charitable donation from Nottingham Forest, soon after Arsenal's foundation in 1886. Two of Dial Square's founding members, Fred Beardsley and Morris Bates, were former Forest players who had moved to Woolwich for work. As they put together the first team in the area, no kit could be found, so Beardsley and Bates wrote home for help and received a set of kit and a ball. The shirt was redcurrant, a dark shade of red, and was worn with white shorts and socks with blue and white hoops.
In what year did Morris Bates stop playing for Forest?

Q: What is a question about this article? If the question is unanswerable, say "unanswerable".
In modern color theory, also known as the RGB color model, red, green and blue are additive primary colors. Red, green and blue light combined together makes white light, and these three colors, combined in different mixtures, can produce nearly any other color. This is the principle that is used to make all of the colors on your computer screen and your television. For example, purple on a computer screen is made by a similar formula to used by Cennino Cennini in the Renaissance to make violet, but using additive colors and light instead of pigment: it is created by combining red and blue light at equal intensity on a black screen. Violet is made on a computer screen in a similar way, but with a greater amount of blue light and less red light.
The RGB color model has three colors in it that are described as what kind of colors?
A: additive primary colors

Context and question: American Idol was based on the British show Pop Idol created by Simon Fuller, which was in turn inspired by the New Zealand television singing competition Popstars. Television producer Nigel Lythgoe saw it in Australia and helped bring it over to Britain. Fuller was inspired by the idea from Popstars of employing a panel of judges to select singers in audition. He then added other elements, such as telephone voting by the viewing public (which at the time was already in use in shows such as the Eurovision Song Contest), the drama of backstories and real-life soap opera unfolding in real time. The show debuted in 2001 in Britain with Lythgoe as showrunnerthe executive producer and production leaderand Simon Cowell as one of the judges, and was a big success with the viewing public.
What show was Pop Idols based on?
Answer: Popstars
