Problem: Gramophone record:

Ultimately, the New Orthophonic curve was disclosed in a publication by R.C. Moyer of RCA Victor in 1953. He traced RCA Victor characteristics back to the Western Electric "rubber line" recorder in 1925 up to the early 1950s laying claim to long-held recording practices and reasons for major changes in the intervening years. The RCA Victor New Orthophonic curve was within the tolerances for the NAB/NARTB, Columbia LP, and AES curves. It eventually became the technical predecessor to the RIAA curve.

Who developed the New Orthophonic curve?
---
A: RCA Victor


Problem: One problem with these assignments is admixture. Many people have a highly varied ancestry. For example, in the United States, colonial and early federal history were periods of numerous interracial relationships, both outside and inside slavery. This has resulted in a majority of people who identify as African American having some European ancestors. Similarly, many people who identify as white have some African ancestors. In a survey in a northeastern U.S. university of college students who identified as "white", about 30% were estimated to have up to 10% African ancestry.
What percentage of African ancestry were 30% of college students identifying as white estimated to have?
---
Answer: 10%


Q: What is a question about this article? If the question is unanswerable, say "unanswerable".
John initially adopted a defensive posture similar to that of 1199: avoiding open battle and carefully defending his key castles. John's operations became more chaotic as the campaign progressed, and Philip began to make steady progress in the east. John became aware in July that Arthur's forces were threatening his mother, Eleanor, at Mirebeau Castle. Accompanied by William de Roches, his seneschal in Anjou, he swung his mercenary army rapidly south to protect her. His forces caught Arthur by surprise and captured the entire rebel leadership at the battle of Mirebeau. With his southern flank weakening, Philip was forced to withdraw in the east and turn south himself to contain John's army.
Why was Philip forced to withdraw in the east?
A: southern flank weakening


Context and question: Although Dominic and the early brethren had instituted female Dominican houses at Prouille and other places by 1227, some of the brethren of the order had misgivings about the necessity of female religious establishments in an order whose major purpose was preaching, a duty in which women could not traditionally engage. In spite of these doubts, women's houses dotted the countryside throughout Europe. There were seventy-four Dominican female houses in Germany, forty-two in Italy, nine in France, eight in Spain, six in Bohemia, three in Hungary, and three in Poland. Many of the German religious houses that lodged women had been home to communities of women, such as Beguines, that became Dominican once they were taught by the traveling preachers and put under the jurisdiction of the Dominican authoritative structure. A number of these houses became centers of study and mystical spirituality in the 14th century. There were one hundred and fifty-seven nunneries in the order by 1358. In that year, the number lessened due to disasters like the Black Death.
What did some of the brethren not have issues with?
Answer: unanswerable


Question: Synnecrosis is a rare type of symbiosis in which the interaction between species is detrimental to both organisms involved. It is a short-lived condition, as the interaction eventually causes death. Because of this, evolution selects against synnecrosis and it is uncommon in nature. An example of this is the relationship between some species of bees and victims of the bee sting. Species of bees who die after stinging their prey inflict pain on themselves (albeit to protect the hive) as well as on the victim. This term is rarely used.
Is there an answer to this question: How common is synnecrosis in the natural world?

Answer: uncommon


Problem: The Times:

In other events of the nineteenth century, The Times opposed the repeal of the Corn Laws until the number of demonstrations convinced the editorial board otherwise, and only reluctantly supported aid to victims of the Irish Potato Famine. It enthusiastically supported the Great Reform Bill of 1832, which reduced corruption and increased the electorate from 400,000 people to 800,000 people (still a small minority of the population). During the American Civil War, The Times represented the view of the wealthy classes, favouring the secessionists, but it was not a supporter of slavery.

What major event did The Times reluctantly support in the nineteenth century despite being initially opposed?
---
A:
Irish Potato Famine
