Please answer this: Extract the answer to the question from the following context. Question: Which is the name of a food additive: E949, forming gas, or power generation? Context: In more recent applications, hydrogen is used pure or mixed with nitrogen (sometimes called forming gas) as a tracer gas for minute leak detection. Applications can be found in the automotive, chemical, power generation, aerospace, and telecommunications industries. Hydrogen is an authorized food additive (E 949) that allows food package leak testing among other anti-oxidizing properties.

Answer: E 949
Problem: Extract the answer to the question from the following context. Question: What do the capacitors and headphones cause on an iPod? Context: The third-generation iPod had a weak bass response, as shown in audio tests. The combination of the undersized DC-blocking capacitors and the typical low-impedance of most consumer headphones form a high-pass filter, which attenuates the low-frequency bass output. Similar capacitors were used in the fourth-generation iPods. The problem is reduced when using high-impedance headphones and is completely masked when driving high-impedance (line level) loads, such as an external headphone amplifier. The first-generation iPod Shuffle uses a dual-transistor output stage, rather than a single capacitor-coupled output, and does not exhibit reduced bass response for any load.

A: high-pass filter
Problem: Given the question: Extract the answer to the question from the following context. Question: The culture of this period is what? Context: Much of the Alpine culture is unchanged since the medieval period when skills that guaranteed survival in the mountain valleys and in the highest villages became mainstays, leading to strong traditions of carpentry, woodcarving, baking and pastry-making, and cheesemaking.

The answer is:
Alpine
input question: Extract the answer to the question from the following context. Question: What happens less than seven days out of 365? Context: Summers are typically warm and humid with a July daily average of 75.6 F (24.2 C). During this time, the city gets a sea breeze off the ocean that often makes daytime temperatures much cooler than inland areas, making Atlantic City a prime place for beating the summer heat from June through September. Average highs even just a few miles west of Atlantic City exceed 85 F (29 C) in July. Near the coast, temperatures reach or exceed 90 F (32 C) on an average of only 6.8 days a year, but this reaches 21 days at nearby Atlantic City Int'l.[a] Winters are cool, with January averaging 35.5 F (2 C). Spring and autumn are erratic, although they are usually mild with low humidity. The average window for freezing temperatures is November 20 to March 25, allowing a growing season of 239 days. Extreme temperatures range from 9 F (23 C) on February 9, 1934 to 104 F (40 C) on August 7, 1918.[b]???
output answer: Near the coast, temperatures reach or exceed 90 F (32 C) on an average of only 6.8 days a year
Extract the answer to the question from the following context. Question: What made it easier to get a pipe organ? Context: Typical stringed instruments of the early period include the harp, lute, vielle, and psaltery, while wind instruments included the flute family (including recorder), shawm (an early member of the oboe family), trumpet, and the bagpipes. Simple pipe organs existed, but were largely confined to churches, although there were portable varieties. Later in the period, early versions of keyboard instruments like the clavichord and harpsichord began to appear. Stringed instruments such as the viol had emerged by the 16th century, as had a wider variety of brass and reed instruments. Printing enabled the standardization of descriptions and specifications of instruments, as well as instruction in their use.

Answer: there were portable varieties
Q: Extract the answer to the question from the following context. Question: What are the continental cups championships? Context: After the World Cup, the most important international football competitions are the continental championships, which are organised by each continental confederation and contested between national teams. These are the European Championship (UEFA), the Copa America (CONMEBOL), African Cup of Nations (CAF), the Asian Cup (AFC), the CONCACAF Gold Cup (CONCACAF) and the OFC Nations Cup (OFC). The FIFA Confederations Cup is contested by the winners of all six continental championships, the current FIFA World Cup champions and the country which is hosting the Confederations Cup. This is generally regarded as a warm-up tournament for the upcoming FIFA World Cup and does not carry the same prestige as the World Cup itself. The most prestigious competitions in club football are the respective continental championships, which are generally contested between national champions, for example the UEFA Champions League in Europe and the Copa Libertadores in South America. The winners of each continental competition contest the FIFA Club World Cup.
A:
FIFA Confederations Cup
