Problem: Pharmaceutical industry:

By the 1890s the profound effect of adrenal extracts on many different tissue types had been discovered, setting off a search both for the mechanism of chemical signalling and efforts to exploit these observations for the development of new drugs. The blood pressure raising and vasoconstrictive effects of adrenal extracts were of particular interest to surgeons as hemostatic agents and as treatment for shock, and a number of companies developed products based on adrenal extracts containing varying purities of the active substance. In 1897 John Abel of Johns Hopkins University identified the active principle as epinephrine, which he isolated in an impure state as the sulfate salt. Industrial chemist Jokichi Takamine later developed a method for obtaining epinephrine in a pure state, and licensed the technology to Parke Davis. Parke Davis marketed epinephrine under the trade name Adrenalin. Injected epinephrine proved to be especially efficacious for the acute treatment of asthma attacks, and an inhaled version was sold in the United States until 2011 (Primatene Mist). By 1929 epinephrine had been formulated into an inhaler for use in the treatment of nasal congestion.

Who first discovered epinephrine?

A: John Abel

Problem: Premier League:

Stadium attendances are a significant source of regular income for Premier League clubs. For the 200910 season, average attendances across the league clubs were 34,215 for Premier League matches with a total aggregate attendance figure of 13,001,616. This represents an increase of 13,089 from the average attendance of 21,126 recorded in the league's first season (199293). However, during the 199293 season the capacities of most stadiums were reduced as clubs replaced terraces with seats in order to meet the Taylor Report's 199495 deadline for all-seater stadiums. The Premier League's record average attendance of 36,144 was set during the 200708 season. This record was then beaten in the 201314 season recording an average attendance of 36,695 with a total attendance of just under 14 million, the highest average in England's top flight since 1950.

Are attendance remittances that important to the Premier League?
---
A: Stadium attendances are a significant source of regular income for Premier League clubs.

Problem: Computer:

The sequence of operations that the control unit goes through to process an instruction is in itself like a short computer program, and indeed, in some more complex CPU designs, there is another yet smaller computer called a microsequencer, which runs a microcode program that causes all of these events to happen.

A microsequencer can be found in what other computer component?
---
A: CPU

Problem: Railway electrification system:

A new approach to avoiding overhead wires is taken by the "second generation" tram/streetcar system in Bordeaux, France (entry into service of the first line in December 2003; original system discontinued in 1958) with its APS (alimentation par sol ground current feed). This involves a third rail which is flush with the surface like the tops of the running rails. The circuit is divided into segments with each segment energized in turn by sensors from the car as it passes over it, the remainder of the third rail remaining "dead". Since each energized segment is completely covered by the lengthy articulated cars, and goes dead before being "uncovered" by the passage of the vehicle, there is no danger to pedestrians. This system has also been adopted in some sections of the new tram systems in Reims, France (opened 2011) and Angers, France (also opened 2011). Proposals are in place for a number of other new services including Dubai, UAE; Barcelona, Spain; Florence, Italy; Marseille, France; Gold Coast, Australia; Washington, D.C., U.S.A.; Brasilia, Brazil and Tours, France.

An old approach to avoiding overhead wires is taken by what system?
