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.

When was the original system discontinued?
Answer: 1958

Problem: While some birds are essentially territorial or live in small family groups, other birds may form large flocks. The principal benefits of flocking are safety in numbers and increased foraging efficiency. Defence against predators is particularly important in closed habitats like forests, where ambush predation is common and multiple eyes can provide a valuable early warning system. This has led to the development of many mixed-species feeding flocks, which are usually composed of small numbers of many species; these flocks provide safety in numbers but increase potential competition for resources. Costs of flocking include bullying of socially subordinate birds by more dominant birds and the reduction of feeding efficiency in certain cases.
What is a cost of flocking?
The answer is the following: bullying of socially subordinate birds by more dominant birds

Work is undertaken from an early age by vast numbers of children in the world and may have a natural place in growing up. Work can contribute to the well-being of children in a variety of ways; children often choose to work to improve their lives, both in the short- and long-term. At the material level, children's work often contributes to producing food or earning income that benefits themselves and their families; and such income is especially important when the families are poor. Work can provide an escape from debilitating poverty, sometimes by allowing a young person to move away from an impoverished environment. Young people often enjoy their work, especially paid work, or when work involves the company of peers. Even when work is intensive and enforced, children often find ways to combine their work with play.
What is an escape for the young that live in poverty?
Work

Input: Nonprofit organization
Canada also permits a variety of charities (including public and private foundations). Charitable status is granted by the Canada Revenue Agency (CRA) upon application by a nonprofit; charities are allowed to issue income tax receipts to donors, must spend a certain percentage of their assets (including cash, investments and fixed assets) and file annual reports in order to maintain their charitable status. In determining whether an organization can become a charity, CRA applies a common law test to its stated objects and activities. These must be:

Input: Article: 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.

Now answer this question: What could epinephrine treat?

Output: nasal congestion

Problem: In practice, not all rule violations will result in a disqualification as the referee may use their own judgement and is not obligated to stop the match. Usually, the only offenses that the referee will see and immediately disqualify the match on (as opposed to having multiple offenses) are low blows, weapon usage, interference, or assaulting the referee. In WWE, a referee must see the violation with their own eyes to rule that the match end in a disqualification (simply watching the video tape is not usually enough) and the referee's ruling is almost always final, although Dusty finishes (named after, and made famous by, Dusty Rhodes) will often result in the referee's decision being overturned. It is not uncommon for the referees themselves to get knocked out during a match, which is commonly referred to by the term "ref bump". While the referee remains "unconscious", wrestlers are free to violate rules until the referee is revived or replaced. In some cases, a referee might disqualify a person under the presumption that it was that wrestler who knocked them out; most referee knockouts are arranged to allow a wrestler, usually a heel, to gain an advantage. For example, a wrestler may get whipped into a referee at a slower speed, knocking the ref down for short amount of time; during that interim period, one wrestler may pin their opponent for a three-count and would have won the match but for the referee being down (sometimes, another referee will sprint to the ring from backstage to attempt to make the count, but by then, the other wrestler has had enough time to kick-out on their own accord).
What must the referee do to rule the match at an end via disqualification?
The answer is the following:
must see the violation with their own eyes
