Input: Identity (social science)
These different explorations of 'identity' demonstrate how difficult a concept it is to pin down. Since identity is a virtual thing, it is impossible to define it empirically. Discussions of identity use the term with different meanings, from fundamental and abiding sameness, to fluidity, contingency, negotiated and so on. Brubaker and Cooper note a tendency in many scholars to confuse identity as a category of practice and as a category of analysis (Brubaker & Cooper 2000, p. 5). Indeed, many scholars demonstrate a tendency to follow their own preconceptions of identity, following more or less the frameworks listed above, rather than taking into account the mechanisms by which the concept is crystallised as reality. In this environment, some analysts, such as Brubaker and Cooper, have suggested doing away with the concept completely (Brubaker & Cooper 2000, p. 1). Others, by contrast, have sought to introduce alternative concepts in an attempt to capture the dynamic and fluid qualities of human social self-expression. Hall (1992, 1996), for example, suggests treating identity as a process, to take into account the reality of diverse and ever-changing social experience. Some scholars have introduced the idea of identification, whereby identity is perceived as made up of different components that are 'identified' and interpreted by individuals. The construction of an individual sense of self is achieved by personal choices regarding who and what to associate with. Such approaches are liberating in their recognition of the role of the individual in social interaction and the construction of identity.

Some scholars try to introduce new concepts to capture the fluid qualities of what?
Output: human social self-expression

Input: Antenna (radio)
So an additional problem beyond canceling the unwanted reactance is of matching the remaining resistive impedance to the characteristic impedance of the transmission line. In principle this can always be done with a transformer, however the turns ratio of a transformer is not adjustable. A general matching network with at least two adjustments can be made to correct both components of impedance. Matching networks using discrete inductors and capacitors will have losses associated with those components, and will have power restrictions when used for transmitting. Avoiding these difficulties, commercial antennas are generally designed with fixed matching elements or feeding strategies to get an approximate match to standard coax, such as 50 or 75 Ohms. Antennas based on the dipole (rather than vertical antennas) should include a balun in between the transmission line and antenna element, which may be integrated into any such matching network.

How many ohms are in are in a standard coax?
Output: 50 or 75

Input: Alloy
In 1906, precipitation hardening alloys were discovered by Alfred Wilm. Precipitation hardening alloys, such as certain alloys of aluminium, titanium, and copper, are heat-treatable alloys that soften when quenched (cooled quickly), and then harden over time. After quenching a ternary alloy of aluminium, copper, and magnesium, Wilm discovered that the alloy increased in hardness when left to age at room temperature. Although an explanation for the phenomenon was not provided until 1919, duralumin was one of the first "age hardening" alloys to be used, and was soon followed by many others. Because they often exhibit a combination of high strength and low weight, these alloys became widely used in many forms of industry, including the construction of modern aircraft.

What happens to precipitation hardening alloys after they quenched?
Output: harden over time

Input: Party leaders of the United States House of Representatives
Unlike in Westminster style legislatures or as with the Senate Majority Leader, the House Majority Leader's duties and prominence vary depending upon the style and power of the Speaker of the House. Typically, the Speaker does not participate in debate and rarely votes on the floor. In some cases, Majority Leaders have been more influential than the Speaker; notably Tom DeLay who was more prominent than Speaker Dennis Hastert. In addition, Speaker Newt Gingrich delegated to Dick Armey an unprecedented level of authority over scheduling legislation on the House floor.

Are snate majority leaders more influential than Speaker of the house??
Output:
Majority Leaders have been more influential than the Speaker
