Input: Party leaders of the United States House of Representatives
In brief, there is disagreement among historical analysts as to the exact time period when the minority leadership emerged officially as a party position. Nonetheless, it seems safe to conclude that the position emerged during the latter part of the 19th century, a period of strong party organization and professional politicians. This era was "marked by strong partisan attachments, resilient patronage-based party organizations, and...high levels of party voting in Congress." Plainly, these were conditions conducive to the establishment of a more highly differentiated House leadership structure.

What were these conditions effective for in the house?
Output: establishment of a more highly differentiated House leadership structure.

Input: Arsenal F.C.
Arsenal have often been stereotyped as a defensive and "boring" side, especially during the 1970s and 1980s; many comedians, such as Eric Morecambe, made jokes about this at the team's expense. The theme was repeated in the 1997 film The Full Monty, in a scene where the lead actors move in a line and raise their hands, deliberately mimicking the Arsenal defence's offside trap, in an attempt to co-ordinate their striptease routine. Another film reference to the club's defence comes in the film Plunkett & Macleane, in which two characters are named Dixon and Winterburn after Arsenal's long-serving full backs – the right-sided Lee Dixon and the left-sided Nigel Winterburn.

What film uses characters named after Arsenal full backs?
Output: Plunkett & Macleane

Input: Copyright infringement
In some jurisdictions, copyright or the right to enforce it can be contractually assigned to a third party which did not have a role in producing the work. When this outsourced litigator appears to have no intention of taking any copyright infringement cases to trial, but rather only takes them just far enough through the legal system to identify and exact settlements from suspected infringers, critics commonly refer to the party as a "copyright troll." Such practices have had mixed results in the U.S.

What do these lawsuits have in the U.S.?
Output:
mixed results
