Problem: Copper:

The concentration of copper in ores averages only 0.6%, and most commercial ores are sulfides, especially chalcopyrite (CuFeS2) and to a lesser extent chalcocite (Cu2S). These minerals are concentrated from crushed ores to the level of 1015% copper by froth flotation or bioleaching. Heating this material with silica in flash smelting removes much of the iron as slag. The process exploits the greater ease of converting iron sulfides into its oxides, which in turn react with the silica to form the silicate slag, which floats on top of the heated mass. The resulting copper matte consisting of Cu2S is then roasted to convert all sulfides into oxides:

Problem: In Lebanon, a part of the Christian population considers "Lebanese" to be in some sense a distinct language from Arabic and not merely a dialect. During the civil war Christians often used Lebanese Arabic officially, and sporadically used the Latin script to write Lebanese, thus further distinguishing it from Arabic. All Lebanese laws are written in the standard literary form of Arabic, though parliamentary debate may be conducted in Lebanese Arabic.
In which form may Latin script be conducted?

Q: What is a question about this article? If the question is unanswerable, say "unanswerable".
On the occasion of a pestilence in the 430s BCE, Apollo's first temple at Rome was established in the Flaminian fields, replacing an older cult site there known as the "Apollinare". During the Second Punic War in 212 BCE, the Ludi Apollinares ("Apollonian Games") were instituted in his honor, on the instructions of a prophecy attributed to one Marcius. In the time of Augustus, who considered himself under the special protection of Apollo and was even said to be his son, his worship developed and he became one of the chief gods of Rome.
When was the Second Punic war?
A: 212 BCE

Context and question: On 24 April 2014, it was reported in the Italian magazine Credere that the late pope could possibly be beatified on 19 October 2014. This report from the magazine further stated that several cardinals and bishops would meet on 5 May to confirm the miracle that had previously been approved, and then present it to Pope Francis who may sign the decree for beatification shortly after that. The Congregation for the Causes of Saints held that meeting and positively concluded that the healing was indeed a miracle that could be attributed to the late pope. The matter shall now soon be presented to the pope for approval.
Who needed to approve the Congregation for the Causes of Saints conclusion that Paul VI performed a miracle?
Answer: pope

Question: The railroads opened up the Great Plains for settlement, for now it was possible to ship wheat and other crops at low cost to the urban markets in the East, and Europe. Homestead land was free for American settlers. Railroads sold their land at cheap rates to immigrants in expectation they would generate traffic as soon as farms were established. Immigrants poured in, especially from Germany and Scandinavia. On the plains, very few single men attempted to operate a farm or ranch by themselves; they clearly understood the need for a hard-working wife, and numerous children, to handle the many chores, including child-rearing, feeding and clothing the family, managing the housework, feeding the hired hands, and, especially after the 1930s, handling paperwork and financial details. During the early years of settlement, farm women played an integral role in assuring family survival by working outdoors. After approximately one generation, women increasingly left the fields, thus redefining their roles within the family. New technology including sewing and washing machines encouraged women to turn to domestic roles. The scientific housekeeping movement, promoted across the land by the media and government extension agents, as well as county fairs which featured achievements in home cookery and canning, advice columns for women regarding farm bookkeeping, and home economics courses in the schools.
Is there an answer to this question: In what decade were washing machines introduced?

Answer: unanswerable

Question: The description or representation of individual and group identity is a central task for psychologists, sociologists and anthropologists and those of other disciplines where "identity" needs to be mapped and defined. How should one describe the identity of another, in ways which encompass both their idiosyncratic qualities and their group memberships or identifications, both of which can shift according to circumstance? Following on from the work of Kelly, Erikson, Tajfel and others Weinreich's Identity Structure Analysis (ISA), is "a structural representation of the individual's existential experience, in which the relationships between self and other agents are organised in relatively stable structures over time with the emphasis on the socio-cultural milieu in which self relates to other agents and institutions" (Weinreich and Saunderson, (eds) 2003, p1). Using constructs drawn from the salient discourses of the individual, the group and cultural norms, the practical operationalisation of ISA provides a methodology that maps how these are used by the individual, applied across time and milieus by the "situated self" to appraise self and other agents and institutions (for example, resulting in the individual's evaluation of self and significant others and institutions).[citation needed]
