Question: In 1654, Otto von Guericke invented the first vacuum pump and conducted his famous Magdeburg hemispheres experiment, showing that teams of horses could not separate two hemispheres from which the air had been partially evacuated. Robert Boyle improved Guericke's design and with the help of Robert Hooke further developed vacuum pump technology. Thereafter, research into the partial vacuum lapsed until 1850 when August Toepler invented the Toepler Pump and Heinrich Geissler invented the mercury displacement pump in 1855, achieving a partial vacuum of about 10 Pa (0.1 Torr). A number of electrical properties become observable at this vacuum level, which renewed interest in further research.

Question: LaserDisc players can provide a great degree of control over the playback process. Unlike many DVD players, the transport mechanism always obeys commands from the user: pause, fast-forward, and fast-reverse commands are always accepted (barring, of course, malfunctions). There were no "User Prohibited Options" where content protection code instructs the player to refuse commands to skip a specific part (such as fast forwarding through copyright warnings). (Some DVD players, particularly higher-end units, do have the ability to ignore the blocking code and play the video without restrictions, but this feature is not common in the usual consumer market.)
Try to answer this question if possible: Where are User Protected Options commonly found on DVDs?
Answer: copyright warnings
Question: The tradition of presenting the trophy immediately after the game did not start until the 1882 final; after the first final in 1872 the trophy was not presented to the winners, Wanderers, until a reception held four weeks later in the Pall Mall Restaurant in London. Under the original rules, the trophy was to be permanently presented to any club which won the competition three times, although when inaugural winners Wanderers achieved this feat by the 1876 final, the rules were changed by FA Secretary CW Alcock (who was also captain of Wanderers in their first victory).
