Problem: Capacitor:

The capacitance of certain capacitors decreases as the component ages. In ceramic capacitors, this is caused by degradation of the dielectric. The type of dielectric, ambient operating and storage temperatures are the most significant aging factors, while the operating voltage has a smaller effect. The aging process may be reversed by heating the component above the Curie point. Aging is fastest near the beginning of life of the component, and the device stabilizes over time. Electrolytic capacitors age as the electrolyte evaporates. In contrast with ceramic capacitors, this occurs towards the end of life of the component.

At what point can the aging effect of a capacitor never be reversed if the component is heated beyond?

Problem: Compared to other team sports, the National Football League preseason is very structured. Every NFL team plays exactly four pre-season exhibition games a year, two at home and two away, with the exception of two teams each year who play a fifth game, the Pro Football Hall of Fame Game. These exhibition games, most of which are held in the month of August, are played for the purpose of helping coaches narrow down the roster from the offseason limit of 90 players to the regular-season limit of 53 players. While the scheduling formula is not as rigid for preseason games as they are for the regular season, there are numerous restrictions and traditions that limit the choices of preseason opponents; teams are also restricted on what days and times they can play these games. Split-squad games, a practice common in baseball and hockey, where a team that is scheduled to play two games on the same day splits their team into two squads, are prohibited. The NFL has played exhibition games in Europe, Japan, Canada, Australia (including the American Bowl in 1999) and Mexico to spread the league's popularity (a game of this type was proposed for China but, due to financial and logistical problems, was eventually canceled). The league has tacitly forbidden the playing of non-league opponents, with the last interleague game having come in 1972 and the last game against a team other than an NFL team (the all-NFL rookie College All-Stars) was held in 1976. Exhibition games are quite unpopular with many fans, who resent having to pay regular-season prices for two home exhibition games as part of a season-ticket package. Numerous lawsuits have been brought by fans and classes of fans against the NFL or its member teams regarding this practice, but none have been successful in halting it.[citation needed] The Pro Bowl, traditionally played after the end of the NFL season (since 2011 is played the week prior to the Super Bowl), is also considered an exhibition game.

Q: What is a question about this article? If the question is unanswerable, say "unanswerable".
Similarities — in systems or even in ideas — that schools share internationally have led to an increase in international student exchanges. The European Socrates-Erasmus Program facilitates exchanges across European universities. The Soros Foundation provides many opportunities for students from central Asia and eastern Europe. Programs such as the International Baccalaureate have contributed to the internationalization of education. The global campus online, led by American universities, allows free access to class materials and lecture files recorded during the actual classes.
 Which program facilitates the exchange students across Asia?
A: unanswerable


Context and question: Following similar conflicts over modernism, the Southern Baptist Convention adhered to conservative theology as its official position. Two new Baptist groups were formed by moderate Southern Baptists who disagreed with the direction in which the Southern Baptist Convention was heading: the Alliance of Baptists in 1987 and the Cooperative Baptist Fellowship in 1991. Members of both groups originally identified as Southern Baptist, but over time the groups "became permanent new families of Baptists."
The Southern Baptist Convention never adhered to what as its official position?
Answer: unanswerable


Question: In 1982, the US Mint began minting pennies coated in copper but made primarily of zinc. With the new zinc pennies, there is the potential for zinc toxicosis, which can be fatal. One reported case of chronic ingestion of 425 pennies (over 1 kg of zinc) resulted in death due to gastrointestinal bacterial and fungal sepsis, whereas another patient, who ingested 12 grams of zinc, only showed lethargy and ataxia (gross lack of coordination of muscle movements). Several other cases have been reported of humans suffering zinc intoxication by the ingestion of zinc coins.
Is there an answer to this question: Ingesting zinc can cause lack of muscle movement and coordination called what?

Answer: ataxia
