input question: Question: "How does an imperfect vacuum differ from true vacuum?"  Context: "Vacuum is space void of matter. The word stems from the Latin adjective vacuus for "vacant" or "void". An approximation to such vacuum is a region with a gaseous pressure much less than atmospheric pressure. Physicists often discuss ideal test results that would occur in a perfect vacuum, which they sometimes simply call "vacuum" or free space, and use the term partial vacuum to refer to an actual imperfect vacuum as one might have in a laboratory or in space. In engineering and applied physics on the other hand, vacuum refers to any space in which the pressure is lower than atmospheric pressure. The Latin term in vacuo is used to describe an object as being in what would otherwise be a vacuum."  Answer:???
output answer: region with a gaseous pressure much less than atmospheric pressure

Question: "Who usually has the ability to vote?"  Context: "In an attempt at reform, Eritrean government officials and NGO representatives have participated in numerous public meetings and dialogues. In these sessions they have answered questions as fundamental as, "What are human rights?", "Who determines what are human rights?", and "What should take precedence, human or communal rights?" In 2007, the Eritrean government also banned female genital mutilation. In Regional Assemblies and religious circles, Eritreans themselves speak out continuously against the use of female circumcision. They cite health concerns and individual freedom as being of primary concern when they say this. Furthermore, they implore rural peoples to cast away this ancient cultural practice. Additionally, a new movement called Citizens for Democratic Rights in Eritrea aimed at bringing about dialogue between the government and opposition was formed in early 2009. The group consists of ordinary citizens and some people close to the government."  Answer:

Q: Question: "What were the benefits for the people during Nasser's reign?"  Context: "Nasser made Egypt fully independent of British influence, and the country became a major power in the developing world under his leadership. One of Nasser's main domestic efforts was to establish social justice, which he deemed a prerequisite to liberal democracy. During his presidency, ordinary citizens enjoyed unprecedented access to housing, education, jobs, health services and nourishment, as well as other forms of social welfare, while feudalistic influence waned. By the end of his presidency, employment and working conditions improved considerably, although poverty was still high in the country and substantial resources allocated for social welfare had been diverted to the war effort."  Answer:
A: social welfare

Question: Question: "What is salt in German?"  Context: "Unique to the development of Dutch is the collaps of older ol/ul/al + dental into ol + dental, followed by vocalisation of pre-consonantal /l/ and after a short vowel, creating the diphthong /ɑu/ e.g., Dutch goud, zout and bout corresponds with Low German Gold, Solt, Bolt; German Gold, Salz, Balt and English gold, salt, bold. This is the most common diphthong along with /ɛi œy/. All three are commonly the only ones considered unique phonemes in Dutch. The tendency for native English speakers is to pronounce Dutch names with /ɛi/ (written as ij or ei) as /aɪ/, (like the English vowel y) which does not normally lead to confusion among native listeners, since in a number of dialects (e.g. in Amsterdam) the same pronunciation is heard."  Answer:
Answer: Salz

[Q]: Question: "Who was pope before 1980, John Paul II or Vatican II?"  Context: "Sacerdotalis caelibatus (Latin for "Of the celibate priesthood"), promulgated on 24 June 1967, defends the Catholic Church's tradition of priestly celibacy in the West. This encyclical was written in the wake of Vatican II, when the Catholic Church was questioning and revising many long-held practices. Priestly celibacy is considered a discipline rather than dogma, and some had expected that it might be relaxed. In response to these questions, the Pope reaffirms the discipline as a long-held practice with special importance in the Catholic Church. The encyclical Sacerdotalis caelibatus from 24 June 1967, confirms the traditional Church teaching, that celibacy is an ideal state and continues to be mandatory for Roman Catholic priests. Celibacy symbolizes the reality of the kingdom of God amid modern society. The priestly celibacy is closely linked to the sacramental priesthood. However, during his pontificate Paul VI was considered generous in permitting bishops to grant laicization of priests who wanted to leave the sacerdotal state, a position which was drastically reversed by John Paul II in 1980 and cemented in the 1983 Canon Law that only the pope can in exceptional circumstances grant laicization."  Answer:
****
[A]: Vatican II

Problem: Given the question: Question: "How did the playing system operate?"  Context: "In 1925, 78.26 rpm was chosen as the standard because of the introduction of the electrically powered synchronous turntable motor. This motor ran at 3600 rpm, such that a 46:1 gear ratio would produce 78.26 rpm. In parts of the world that used 50 Hz current, the standard was 77.92 rpm (3,000 rpm with a 77:2 ratio), which was also the speed at which a strobe disc with 77 lines would "stand still" in 50 Hz light (92 lines for 60 Hz). After World War II these records were retroactively known as 78s, to distinguish them from other newer disc record formats. Earlier they were just called records, or when there was a need to distinguish them from cylinders, disc records."  Answer:
