Question: Who is the oldest of Harry Potter's aunt and uncle? Passage:During the summer holidays with his aunt Petunia and uncle Vernon, 15-year-old Harry Potter and his cousin Dudley are attacked by Dementors. After openly using magic to save Dudley and himself, Harry is expelled from Hogwarts, but his expulsion is postponed pending a hearing at the Ministry of Magic. Harry is whisked off by a group of wizards including Mad-Eye Moody, Remus Lupin, and several new faces, including Nymphadora Tonks, a bubbly young Metamophagus (a witch or wizard who can change his or her appearance without a potion or spell), and Kingsley Shacklebolt, a senior Auror, to Number 12, Grimmauld Place, the childhood home of Sirius Black. The building also serves as the headquarters of the Order of the Phoenix, of which Mr. and Mrs. Weasley and Sirius are also members. Ron Weasley and Hermione Granger explain that the Order is a secret organisation led by Hogwarts headmaster Albus Dumbledore dedicated to fighting Lord Voldemort and his followers, the Death Eaters. From the members of the Order, Harry and the others learn Voldemort is seeking an object he did not have prior to his first defeat and assume this object to be a weapon of some sort. Harry learns the Ministry of Magic, led by Cornelius Fudge, is refusing to acknowledge Voldemort's return because of the panic and chaos doing so would cause. Harry also learns the Daily Prophet has been running a smear campaign against him and Dumbledore.

Question: Were Caton and Beck both from Poland? Passage:From the bioelectricity of nerves, Marxow turned his attention, from 1876 on, to the global electrical activity of the cerebral hemispheres. Neuroanatomists had already determined at the time that its nervous tissue was also composed of cells (the neurons), with their bodies mainly located in the gray matter, and filamentary prolongations, the dendrites and the axons. Thus, it was only natural to assume that they would also display electrical activity. This important discovery, however, had not been made until that time, because many desynchronized electrical potentials with different polarities produce a cumulative global potential which is actually very small and difficult to detect with the sensitivity range of the measuring devices available at the time. Despite this, Marxow was able to prove for the first time that the peripheral stimulation of sensory organs, such as vision and hearing were able to provoke event-related small electrical potential swings on the surface of the cerebral cortex which was related to the projection of those senses. Strangely, however, Marxow did not publish his results, choosing instead to deposit them in a bank safe, with instructions to reveal them in 1883 only. Meanwhile, the first publications about what was later to be called the electroencephalogram came to light, independently demonstrated by Richard Caton (1842–1926), in Great Britain, and Adolf Beck (1863–1942) in Poland, both using laboratory animals.

Question: Who owned the record company where After School Special recorded several releases? Passage:Prior to their formation, David Jones, the main songwriter in Enemy You, recorded several releases with his pop punk band After School Special on Mutant Pop Records. The group never toured or played a show, but still had a small dedicated following. In 1997, Enemy You was formed and began rehearsing together. They were heavily inspired by Bad Religion and other melodic punk acts. After Enemy You began writing tunes together as a band they received interest from Ben Weasel and his fledgling label, Panic Button Records. Ben would often call Fat Wreck Chords, and heard about the band through Chris, who was the bassist for Enemy You, and an employee at Fat Wreck Chords. This led to their debut appearance on the four-way split dubbed Four On The Floor alongside Screeching Weasel, Teen Idols and Moral Crux. This was followed by their debut album Where No One Knows My Name in 1999. Based on the album's success the band was asked to open for a number of notable punk bands including Bouncing Souls, Lagwagon, Bad Religion, T.S.O.L., Mad Caddies, and NOFX. The band released a 7-inch on the Fat Club series on Fat Wreck Chords. They followed that with an 80's-themed seven inch EP that came out on Geykido Comet Records, titled "Video to Radio." Geykido Comet Records re-released the EP in 2017, with all the proceeds going to suicide prevention. Around this time, guitarist, Ken Yamazaki, started to play guitar for the Hardcore punk band, Western Addiction. He still stayed with Enemy You, though. In 2005 the band released their second album, "Stories Never Told" on Red Scare Industries. David was friends with label owner, Toby Jeg, and the label also eventually re-released Where No One Knows My Name. Enemy You then signed with Nitro Records. Their third studio album, Fade Away was released as an iTunes Store exclusive on December 2, 2008, after being shelved for a few years. Vocalist David Jones committed suicide in March of 2015.
