Here is a question about this article: Some of Elvis Presley's early singles on Sun Records might have sold more copies on 78 than on 45. This is because the majority of those sales in 1954–55 were to the "hillbilly" market in the South and Southwestern United States, where replacing the family 78 rpm player with a new 45 rpm player was a luxury few could afford at the time. By the end of 1957, RCA Victor announced that 78s accounted for less than 10% of Presley's singles sales, essentially announcing the death throes of the 78 rpm format. The last Presley single released on 78 in the United States was RCA Victor 20-7410, I Got Stung/One Night (1958), while the last 78 in the UK was RCA 1194, A Mess Of Blues/Girl Of My Best Friend (1960).
What is the answer to this question: What percentage of Elvis Presley's single sales were of 78s?
****
So... less than 10%


Here is a question about this article: New Haven lies in the transition between a humid continental climate (Köppen climate classification: Dfa) and humid subtropical climate (Köppen Cfa), but having more characteristics of the former, as is typical of much of the New York metropolitan area. Summers are humid and warm, with temperatures exceeding 90 °F (32 °C) on 7–8 days per year. Winters are cold with moderate snowfall interspersed with rainfall and occasionally mixed precipitation. The weather patterns that affect New Haven result from a primarily offshore direction, thus reducing the marine influence of Long Island Sound—although, like other marine areas, differences in temperature between areas right along the coastline and areas a mile or two inland can be large at times.
What is the answer to this question: What baseline temperature threshold do temperatures normally exceed throughout the summer in New Haven?
****
So... 90 °F (32 °C)


Here is a question about this article: As a teenager, he was greatly troubled by the Metaphysics of Aristotle, which he could not understand until he read al-Farabi's commentary on the work. For the next year and a half, he studied philosophy, in which he encountered greater obstacles. In such moments of baffled inquiry, he would leave his books, perform the requisite ablutions, then go to the mosque, and continue in prayer till light broke on his difficulties. Deep into the night, he would continue his studies, and even in his dreams problems would pursue him and work out their solution. Forty times, it is said, he read through the Metaphysics of Aristotle, till the words were imprinted on his memory; but their meaning was hopelessly obscure, until one day they found illumination, from the little commentary by Farabi, which he bought at a bookstall for the small sum of three dirhams. So great was his joy at the discovery, made with the help of a work from which he had expected only mystery, that he hastened to return thanks to God, and bestowed alms upon the poor.
What is the answer to this question: How much did Avicenna pay for the book that helped him understand the Aristotle text?

So...
three dirhams
