Problem: Pub:

Later, the public bars gradually improved until sometimes almost the only difference was in the prices, so that customers could choose between economy and exclusivity (or youth and age, or a jukebox or dartboard).[citation needed] With the blurring of class divisions in the 1960s and 1970s,[citation needed] the distinction between the saloon and the public bar was often seen as archaic,[citation needed] and was frequently abolished, usually by the removal of the dividing wall or partition.[citation needed] While the names of saloon and public bar may still be seen on the doors of pubs, the prices (and often the standard of furnishings and decoration) are the same throughout the premises, and many pubs now comprise one large room. However the modern importance of dining in pubs encourages some establishments to maintain distinct rooms or areas.

What was a common way of removing the division between the saloon and bar?
---
A: removal of the dividing wall or partition

Problem: FC Barcelona:

In 1922, the number of supporters had surpassed 20,000 and by lending money to the club, Barca was able to build the larger Camp de Les Corts, which had an initial capacity of 20,000 spectators. After the Spanish Civil War the club started attracting more members and a larger number of spectators at matches. This led to several expansion projects: the grandstand in 1944, the southern stand in 1946, and finally the northern stand in 1950. After the last expansion, Les Corts could hold 60,000 spectators.

How many people could Camp de Les Corts hold?
---
A: 20,000

Problem: Energy:

Energy transfer can be considered for the special case of systems which are closed to transfers of matter. The portion of the energy which is transferred by conservative forces over a distance is measured as the work the source system does on the receiving system. The portion of the energy which does not do work during the transfer is called heat.[note 4] Energy can be transferred between systems in a variety of ways. Examples include the transmission of electromagnetic energy via photons, physical collisions which transfer kinetic energy,[note 5] and the conductive transfer of thermal energy.

The portion of energy which works during the transfer is called what?
---
A:
unanswerable
