Question: How many species of the Aru Flying fox are there? Passage:Of the 62 flying fox species evaluated by the IUCN as of 2018, 3 are considered critically endangered: the Aru flying fox, Livingstone's fruit bat, and the Vanikoro flying fox. Another 7 species are listed as endangered; 20 are listed as vulnerable, 6 as near threatened, 14 as least concern, and 8 as data deficient. A further 4 are listed as extinct: the dusky flying fox, the large Palau flying fox, the small Mauritian flying fox, and the Guam flying fox. Over half of the species are threatened today with extinction, and in particular in the Pacific, a number of species have died out as a result of hunting, deforestation, and predation by invasive species. Six flying fox species are believed to have gone extinct from 1864 to 2014: the Guam, large Palau, small Mauritian, dusky, large Samoan, and the small Samoan flying foxes.

Question: Which film won the Palme d'or the year that Dzieje grzechu was nominated? Passage:Borowczyk moved into live-action feature film with Goto, l'île d'amour (Goto, Isle of Love) (1968) and Blanche (1971), both tales of illicit love thwarted by jealous husbands, and both starring his own wife, Ligia Branice. One of his most appreciated films of this period, Dzieje grzechu (A Story of Sin) (1975), which was nominated for Palme d'or, is an adaptation of a Polish literary classic by Stefan Żeromski. Like his 1966 short film Rosalie (a Guy de Maupassant adaptation and a Silver Bear winner), Dzieje grzechu had successfully rendered the themes of seduction and infanticide. Contes immoraux (Immoral Tales) (1973) and his later work, including Interno di un convento (Behind Convent Walls) (1977) (inspired by Promenades dans Rome of Stendhal) and Cérémonie d'amour (Rites of Love) (1988) have been controversial, lauded by some for their unique surrealist vision and derided by others as contentless pornography. Especially, La Bête (The Beast, 1975) (based on the novel Lokis by Prosper Mérimée and originally conceived in 1972 as a film on its own, but then in 1973 as the fifth story in Contes immoraux) was seen by many as a decline in the director's career after Dzieje grzechu, except in France, where it was hailed by prominent critics such as Ado Kyrou. His 1980 film Lulu was based on the eponymous character created by Frank Wedekind.

Question: Along what river is the city located where Dulfu attended Hungarian-language primary school and gymnasium from 1864 to 1871? Passage:Born in Tohat, Maramureș County, his parents were Nichifor Dulfu and his wife Agapia (née Bran), members of the rural intellectual class. From early childhood, his mother inspired a love of stories in him. He attended Hungarian-language primary school and gymnasium in Baia Mare from 1864 to 1871, earning top marks, and went to high school in the same town from 1872. In 1876, he graduated from high school in Cluj, where he studied for two years. He attended Franz Joseph University in the latter city, earning a doctorate in philosophy in 1881. His thesis, written in Hungarian, dealt with the work of Vasile Alecsandri, surveyed the Romanian literary context and included a dozen poems translated by Dulfu. After graduation, he moved to the Romanian Old Kingdom and worked as a teacher. After a brief stint in the capital Bucharest, he directed and taught at a school in Turnu Severin for the 1881-1882 year. Beginning in 1882, he again taught philosophy and later Romanian in Bucharest; one of the two schools where he worked was for girls. He came to know faculty colleague Ioan Slavici, as well as Mihail Eminescu, Alexandru Vlahuță and Bogdan Petriceicu Hasdeu. In 1886, he married Elena Mateescu, with whom he had four children and who encouraged his work as a writer. He obtained Romanian citizenship in 1891. During World War I, he worked as a postal censor in the temporary capital of Iași, where an illness claimed one of his daughters. Although normally a disciplined teacher, he lost his composure on December 1, 1918, the day the union of Transylvania with Romania was proclaimed; cutting short the lesson and visibly moved, he explained the significance of the event to his pupils. In 1921, he retired from the girls' school, as the pupils daily reminded him of his deceased daughter.
