Problem: Although large wild dogs, like wolves, are apex predators, they can be killed in territory disputes with wild animals. Furthermore, in areas where both dogs and other large predators live, dogs can be a major food source for big cats or canines. Reports from Croatia indicate wolves kill dogs more frequently than they kill sheep. Wolves in Russia apparently limit feral dog populations. In Wisconsin, more compensation has been paid for dog losses than livestock. Some wolf pairs have been reported to prey on dogs by having one wolf lure the dog out into heavy brush where the second animal waits in ambush. In some instances, wolves have displayed an uncharacteristic fearlessness of humans and buildings when attacking dogs, to the extent that they have to be beaten off or killed.
Like wolves, big domesticated dogs are considered what type of predator?
The answer is the following: apex

Input: The Sun (United Kingdom)
Politically, the paper's stance was less clear under Prime Minister Gordon Brown who succeeded Blair in June 2007. Its editorials were critical of many of Brown's policies and often more supportive of those of Conservative leader David Cameron. Rupert Murdoch, head of The Sun's parent company News Corporation, speaking at a 2007 meeting with the House of Lords Select Committee on Communications, which was investigating media ownership and the news, said that he acts as a "traditional proprietor". This means he exercises editorial control on major issues such as which political party to back in a general election or which policy to adopt on Europe.

Who was the Conservative leader that The Sun often supported?
Output: David Cameron

Input: Article: Through the 1860s, Victoria relied increasingly on a manservant from Scotland, John Brown. Slanderous rumours of a romantic connection and even a secret marriage appeared in print, and the Queen was referred to as "Mrs. Brown". The story of their relationship was the subject of the 1997 movie Mrs. Brown. A painting by Sir Edwin Henry Landseer depicting the Queen with Brown was exhibited at the Royal Academy, and Victoria published a book, Leaves from the Journal of Our Life in the Highlands, which featured Brown prominently and in which the Queen praised him highly.

Now answer this question: Which book did Victoria publish that did nothing to take away from the rumors about her and John Brown?

Output: Leaves from the Journal of Our Life in the Highlands

Article: A tile mosaic is a digital image made up of individual tiles, arranged in a non-overlapping fashion, e.g. to make a static image on a shower room or bathing pool floor, by breaking the image down into square pixels formed from ceramic tiles (a typical size is 1 in 1 in (25 mm 25 mm), as for example, on the floor of the University of Toronto pool, though sometimes larger tiles such as 2 in 2 in (51 mm 51 mm) are used). These digital images are coarse in resolution and often simply express text, such as the depth of the pool in various places, but some such digital images are used to show a sunset or other beach theme.

Question: How should the tiles be aligned next to each other?
Ans: in a non-overlapping fashion
