Question: When a Teletype 33 ASR equipped with the automatic paper tape reader received a Control-S (XOFF, an abbreviation for transmit off), it caused the tape reader to stop; receiving Control-Q (XON, "transmit on") caused the tape reader to resume. This technique became adopted by several early computer operating systems as a "handshaking" signal warning a sender to stop transmission because of impending overflow; it persists to this day in many systems as a manual output control technique. On some systems Control-S retains its meaning but Control-Q is replaced by a second Control-S to resume output. The 33 ASR also could be configured to employ Control-R (DC2) and Control-T (DC4) to start and stop the tape punch; on some units equipped with this function, the corresponding control character lettering on the keycap above the letter was TAPE and TAPE respectively.
Try to answer this question if possible: What caused the automatic paper tape reader to start again?
Answer: Control-Q
Question: Fryderyk may have had some piano instruction from his mother, but his first professional music tutor, from 1816 to 1821, was the Czech pianist Wojciech Zywny. His elder sister Ludwika also took lessons from Zywny, and occasionally played duets with her brother. It quickly became apparent that he was a child prodigy. By the age of seven Fryderyk had begun giving public concerts, and in 1817 he composed two polonaises, in G minor and B-flat major. His next work, a polonaise in A-flat major of 1821, dedicated to Zywny, is his earliest surviving musical manuscript.

Answer: 7
Question: After the fall of Napoleon, not only was Napoleonic Code retained by conquered countries including the Netherlands, Belgium, parts of Italy and Germany, but has been used as the basis of certain parts of law outside Europe including the Dominican Republic, the US state of Louisiana and the Canadian province of Quebec. The memory of Napoleon in Poland is favorable, for his support for independence and opposition to Russia, his legal code, the abolition of serfdom, and the introduction of modern middle class bureaucracies.
Try to answer this question if possible: Poland views Napoleon in a positive light partially based on his opposition to what country?

Question: The Brazilian federal constitution states that the power to enter into treaties is vested in the president and that such treaties must be approved by Congress (articles 84, clause VIII, and 49, clause I). In practice, this has been interpreted as meaning that the executive branch is free to negotiate and sign a treaty, but its ratification by the president is contingent upon the prior approval of Congress. Additionally, the Federal Supreme Court has ruled that, following ratification and entry into force, a treaty must be incorporated into domestic law by means of a presidential decree published in the federal register in order to be valid in Brazil and applicable by the Brazilian authorities.
Try to answer this question if possible: What Brazilian institution has ruled that a treaty must be incorporated into domestic law by means of a presidential decree?
Answer:
the Federal Supreme Court
