Problem: Chicago Cubs:

In 2013, Tom Ricketts and team president Crane Kenney unveiled plans for a five-year, $575 million privately funded renovation of Wrigley Field. Called the 1060 Project, the proposed plans included vast improvements to the stadium's facade, infrastructure, restrooms, concourses, suites, press box, bullpens, and clubhouses, as well as a 6,000-square foot jumbotron to be added in the left field bleachers, batting tunnels, a 3,000-square-foot video board in right field, and, eventually, an adjacent hotel, plaza, and office-retail complex. In previously years mostly all efforts to conduct any large-scale renovations to the field had been opposed by the city, former mayor Richard M. Daley (a staunch White Sox fan), and especially the rooftop owners.

Although the city lost the status of state capital to Columbia in 1786, Charleston became even more prosperous in the plantation-dominated economy of the post-Revolutionary years. The invention of the cotton gin in 1793 revolutionized the processing of this crop, making short-staple cotton profitable. It was more easily grown in the upland areas, and cotton quickly became South Carolina's major export commodity. The Piedmont region was developed into cotton plantations, to which the sea islands and Lowcountry were already devoted. Slaves were also the primary labor force within the city, working as domestics, artisans, market workers, and laborers.
In what year was the cotton gin rejected?
A: unanswerable

Question: In dominant-party systems, opposition parties are allowed, and there may be even a deeply established democratic tradition, but other parties are widely considered to have no real chance of gaining power. Sometimes, political, social and economic circumstances, and public opinion are the reason for others parties' failure. Sometimes, typically in countries with less of an established democratic tradition, it is possible the dominant party will remain in power by using patronage and sometimes by voting fraud. In the latter case, the definition between dominant and one-party system becomes rather blurred. Examples of dominant party systems include the People's Action Party in Singapore, the African National Congress in South Africa, the Cambodian People's Party in Cambodia, the Liberal Democratic Party in Japan, and the National Liberation Front in Algeria. One-party dominant system also existed in Mexico with the Institutional Revolutionary Party until the 1990s, in the southern United States with the Democratic Party from the late 19th century until the 1970s, in Indonesia with the Golkar from the early 1970s until 1998.
Is there an answer to this question: What are some of the reasons for a party's failure?

Answer: political, social and economic circumstances, and public opinion
