Background: Abby Newman is a fictional character from the American CBS soap opera The Young and the Restless. The character was introduced on November 13, 2000, as the daughter of Ashley Abbott (Eileen Davidson) and Victor Newman (Eric Braeden). The role was portrayed by Darcy Rose Byrnes as a child until 2008, when the character was rapidly aged to a teenager, with Hayley Erin assuming the role the following year. In 2010, the character was rapidly aged again to an adult, with Marcy Rylan cast as Erin's replacement.
Context: In 2010, Abby was romantically linked with Daniel Romalotti. Soon after, she began flirting with Daniel Romalotti when the two begin sharing romantic interactions. Abby had sex with Daniel in the Newman pool house, and she recorded it for her reality show. Abby and Daniel's relationship was outed when Nikki Newman and Daniel's mother, Phyllis Summers, saw Abby and Daniel making out in public. Their relationship continued for a while, but when Abby found out that Daniel fathered a child with Daisy Carter, she broke up with him.  Upon Abby's return, Abby was romantically linked to Marco Dapper's Carmine Basco, when the two begin dating much to him being shunned by the town, but Abby is able to convince some of them that Carmine is a good soul. However the relationship wasn't given closure upon Rylan's exit from the soap opera. Dapper admitted in an interview that the writers "didn't really know what to do with him after Abby left the first time". He also stated that he hoped Carmine would have more of a "darker turn", and that he still believes there is a "left over spark" with Abby as their storyline "was never finished" and "nothing was wrapped up properly".  Shortly after her failed relationship with Carmine, Abby took romantic interest in Detective Ignacio Serricchio's Alex Chavez, and they began dating. However, the relationship was short-lived when the writers soon began developing Abby's relationship with Redaric Williams's Tyler Michaelson. According to Williams, Tyler is "intrigued" by Abby's unpredictable nature and said that their natural attraction could lead to romance. However, Williams hinted that Tyler's interest in Abby could be his attempt to "suppress his feelings" for Lily. Abby and Tyler's relationship faced some interference from Tyler's ex-fiancee, Mariah Copeland, but she seemed to back off leading to Tyler proposing to Abby and they became engaged. However, Abby breaks off the engagement when Mariah's interferences causes Abby to believe Tyler is still in love with Mariah.
Question: Did they break up?
Answer: when Abby found out that Daniel fathered a child with Daisy Carter, she broke up with him.

Problem: Background: Harold Adams Innis (; November 5, 1894 - November 8, 1952) was a Canadian professor of political economy at the University of Toronto and the author of seminal works on media, communication theory, and Canadian economic history. Despite his dense and difficult prose, Innis was one of Canada's most original thinkers. He helped develop the staples thesis, which holds that Canada's culture, political history, and economy have been decisively influenced by the exploitation and export of a series of "staples" such as fur, fishing, lumber, wheat, mined metals, and coal.
Context: Harold Innis wrote his PhD thesis on the history of the Canadian Pacific Railway (CPR). The completion of Canada's first transcontinental railway in 1885 had been a defining moment in Canadian history. Innis's thesis, eventually published as a book in 1923, can be seen as an early attempt to document the railway's significance from an economic historian's point of view. It uses voluminous statistics to underpin its arguments. Innis maintains that the difficult and expensive construction project was sustained by fears of American annexation of the Canadian West.  Innis argues that "the history of the Canadian Pacific Railroad is primarily the history of the spread of Western civilization over the northern half of the North American continent". As Robert Babe notes, the railway brought industrialization, transporting coal and building supplies to manufacturing sites. It was also a kind of communications medium that contributed to the spread of European civilization. Babe writes that, for Innis, the CPR's equipment "comprised a massive, energy-consuming, fast-moving, powerful, capital-intensive 'sign' dropped into the very midst of indigenous peoples, whose entire way of life was disrupted, and eventually shattered as a result.  Communications scholar Arthur Kroker argues that Innis's study of the Canadian Pacific Railway was only the first in which he attempted to demonstrate that "technology is not something external to Canadian being; but on the contrary, is the necessary condition and lasting consequence of Canadian existence". It also reflected Innis's lifelong interest in the exercise of economic and political power. His CPR history ends, for example, with a recounting of Western grievances against economic policies, such as high freight rates and the steep import tariffs designed to protect fledgling Canadian manufacturers. Westerners complained that this National Policy funnelled money from Prairie farmers into the pockets of the Eastern business establishment. "Western Canada", Innis wrote, "has paid for the development of Canadian nationality, and it would appear that it must continue to pay. The acquisitiveness of Eastern Canada shows little sign of abatement."
