Problem: Ann Arbor, Michigan:

The Ann Arbor News, owned by the Michigan-based Booth Newspapers chain, is the major daily newspaper serving Ann Arbor and the rest of Washtenaw County. The newspaper ended its 174-year print run in 2009, due to economic difficulties. It was replaced by AnnArbor.com, but returned to a limited print publication under its former name in 2013. Another Ann Arbor-based publication that has ceased production was the Ann Arbor Paper, a free monthly. Ann Arbor has been said to be the first significant city to lose its only daily paper. The Ann Arbor Chronicle, an online newspaper, covered local news, including meetings of the library board, county commission, and DDA until September 3, 2014.

Problem: YouTube:

In May 2007, YouTube launched its Partner Program, a system based on AdSense which allows the uploader of the video to share the revenue produced by advertising on the site. YouTube typically takes 45 percent of the advertising revenue from videos in the Partner Program, with 55 percent going to the uploader. There are over a million members of the YouTube Partner Program. According to TubeMogul, in 2013 a pre-roll advertisement on YouTube (one that is shown before the video starts) cost advertisers on average $7.60 per 1000 views. Usually no more than half of eligible videos have a pre-roll advertisement, due to a lack of interested advertisers. Assuming pre-roll advertisements on half of videos, a YouTube partner would earn 0.5 X $7.60 X 55% = $2.09 per 1000 views in 2013.

Who does 45% of the advertising revenue go to?

A: unanswerable


Problem: Melbourne:

Melbourne has a temperate oceanic climate (Köppen 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.
