Question: Which country that Austria has a border barrier with has the highest population? Passage:Austrian border barriers are border barriers and migration management facilities constructed by Austria between November 2015 and January 2016 on its border with Slovenia and in 2016 on its border with Italy, as a response to European migrant crisis. They are located on internal European Union borders, since Austria, Italy, and Slovenia are members of the EU and the free travel Schengen Area with a common visa policy. The barrier on the Slovenian border is several kilometres long, located near the busiest border crossing, Spielfeld-Sentilj, and includes police facilities for screening and processing migrants. Another migration management facility with barriers located on Austria's Italian border near Brenner, South Tyrol was constructed in 2016.

Question: How old was Merrilyn Gann when Simmons appeared in the telefim version of Carrie? Passage:Chelan Simmons, who played Pennywise's first victim Laurie Ann Winterbarger, had her first non-commercial experience with It; she would later be known for appearing in several 21st-century budget horror films and a 2002 telefilm version of Carrie. Due to her fear of clowns, she has admitted to never seeing the miniseries or reading the original novel. The girl's mother is portrayed by Merrilyn Gann. Two Gemini Award winners, Nicola Cavendish and Venus Terzo, appear as a desk clerk and a woman named Lyndi respectively. Terence Kelly, who portrays officer Nell, was nominated for a Gemini for another role as an officer in Reg Serge. Two veterans of The X-Files appear in It: William B. Davis as Mr. Gedreau, and Megan Leitch as a library aide Richie talks to while being taunted by Pennywise. Other well-known Canadian actors in the miniseries include Laura Harris as Loni; Garry Chalk, most known for voice acting, as Eddie's gym class coach; Jay Brazeau as a taxi driver; Paul Batten as Eddie's pharmacist; Donna Peerless and Tom Heaton as teachers Miss Douglas and Mr. Keene; and Kim Kondrashoff, Helena Yea, and Charles Siegel as the Losers' classmates, Joey, Rose, and Nat respectively.

Question: Was Theophrastus still alive when Epicurus founded The Garden? Passage:In Athens, the first private pleasure gardens appear in literary sources in the fourth century. The Academy had its site in an ancient grove of plane trees sacred to an obscure archaic hero, Akademos. Sacred groves were never actively planted, but simply existed from time immemorial and were recognized as sacred: they have no place in the history of gardens, save as a resort for contemplation and, at Plato's Academy, for intellectual discourse. By contrast, the olive trees in the Academy, watered by the river Cephissus, were planted, grown, it was said, from slips taken of the sacred olive at the Erechtheum. The temenos, or sacred ground, of the Academy was walled round, for ritual reasons, as pleasure gardens would be, for practical ones; within its precincts were buildings: small temples, shrines and tombs, in addition to that of the presiding hero. In 322 BCE Theophrastus, the father of botany, inherited Aristotle's garden, along with his scholars and his library; of the garden we know only that it had a walk, and that Theophrastus lectured there: it may have been in some respects a botanical garden with a scientific rather than recreational purpose. On his return to Athens in 306 BCE, the philosopher Epicurus founded The Garden, a school named for the garden he owned about halfway between the Stoa and the Academy that served as the school's meeting place; little is actually known of the ascetic philosopher's garden, though in cultural history it grew retrospectively in delight: of his garden at Geneva, Les Delices, Voltaire could exclaim, with more enthusiasm than history, "It is the palace of a philosopher with the gardens of Epicurus it is a delicious retreat". Gardens of Adonis, under Syrian influence, were simple plantings of herbal seedlings grown in saucers and pots, which, when they collapsed in the heat of summer, were the signal for mourning for Adonis among his female adherents: these were not gardens in any general sense.
