Problem: After 1517, when the new invention of printing made these texts widely available, the Dutch humanist Erasmus, who had studied Greek at the Venetian printing house of Aldus Manutius, began a philological analysis of the Gospels in the spirit of Valla, comparing the Greek originals with their Latin translations with a view to correcting errors and discrepancies in the latter. Erasmus, along with the French humanist Jacques Lefevre d'Etaples, began issuing new translations, laying the groundwork for the Protestant Reformation. Henceforth Renaissance humanism, particularly in the German North, became concerned with religion, while Italian and French humanism concentrated increasingly on scholarship and philology addressed to a narrow audience of specialists, studiously avoiding topics that might offend despotic rulers or which might be seen as corrosive of faith. After the Reformation, critical examination of the Bible did not resume until the advent of the so-called Higher criticism of the 19th-century German Tubingen school.

Problem: The question of priority for the variable resistance feature of the telephone was raised by the examiner before he approved Bell's patent application. He told Bell that his claim for the variable resistance feature was also described in Gray's caveat. Bell pointed to a variable resistance device in Bell's previous application in which Bell described a cup of mercury, not water. Bell had filed the mercury application at the patent office a year earlier on February 25, 1875, long before Elisha Gray described the water device. In addition, Gray abandoned his caveat, and because he did not contest Bell's priority, the examiner approved Bell's patent on March 3, 1876. Gray had reinvented the variable resistance telephone, but Bell was the first to write down the idea and the first to test it in a telephone.
What liquid did Bell use in his first application?

Answer: mercury

Problem: The first recorded use of the term (or its cognates in other languages) is in the New Testament, in Acts 11:26, after Barnabas brought Saul (Paul) to Antioch where they taught the disciples for about a year, the text says: "[...] the disciples were called Christians first in Antioch." The second mention of the term follows in Acts 26:28, where Herod Agrippa II replied to Paul the Apostle, "Then Agrippa said unto Paul, Almost thou persuadest me to be a Christian." The third and final New Testament reference to the term is in 1 Peter 4:16, which exhorts believers: "Yet if [any man suffer] as a Christian, let him not be ashamed; but let him glorify God on this behalf."
In which book of the Old Testament does Paul reply to Herod Agrippa?
