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: What was the population of Reunion the year that Houellebecq was born? Passage:Houellebecq was born in 1956 on the French island of Reunion, the son of Lucie Ceccaldi, a French doctor born in Algeria of Corsican descent, and Rene Thomas, a ski instructor and mountain guide. He lived in Algeria from the age of five months until 1961, with his maternal grandmother. In a lengthy autobiographical article published on his website (now defunct), he states that his parents "lost interest in [his] existence pretty quickly", and at the age of six, he was sent to France to live with his paternal grandmother, a communist, while his mother left to live a hippie lifestyle in Brazil with her recent boyfriend. His grandmother's maiden name was Houellebecq, which he took as his pen name. Later, he went to Lycee Henri Moissan, a high school at Meaux in the north-east of Paris, as a boarder. He then went to Lycee Chaptal in Paris to follow preparation courses in order to qualify for grandes ecoles (elite schools). He began attending the Institut National Agronomique Paris-Grignon in 1975. He started a literary review called Karamazov (named after Fyodor Dostoevsky's last novel) and wrote poetry.
