Question: A Curtain of Green was written by the author of what nationality?
Context: Eudora Alice Welty (April 13, 1909 – July 23, 2001) was an American short story writer and novelist who wrote about the American South.  Her novel "The Optimist's Daughter" won the Pulitzer Prize in 1973.  Welty was awarded the Presidential Medal of Freedom, among numerous awards including the Order of the South.  She was the first living author to have her works published by the Library of America.  Her house in Jackson, Mississippi has been designated as a National Historic Landmark and is open to the public as a house museum. The Italian, or the Confessional of the Black Penitents (1797) is a Gothic novel written by the English author Ann Radcliffe.  It is the last book Radcliffe published during her lifetime (she would go on to write the novel "Gaston de Blondeville", which was published posthumously in 1826).  "The Italian" has a dark, mysterious and somber tone, and concerns the themes of love, devotion and persecution by the Holy Inquisition.  The novel also deals with issues prevalent at the time of the French Revolution, such as religion, aristocracy, and nationality.  Radcliffe's renowned use of veiled imagery is considered to have reached its height of sophistication and complexity in "The Italian"; concealment and disguise are central motifs of the novel.  In line with late 18th-century sensibility and its parallel fetishisation of the sublime and the sentimentally pastoral, the heightened emotional states of Radcliffe's characters are often reflected through the pathetic fallacy.  The novel is noted for its extremely effective antagonist, Father Schedoni. Carazamba is a 1953 "criollista" novel by the Guatemalan writer Virgilio Rodríguez Macal.  The work was the first novel written by the author, and gained first prize in the Central American Floral Games in 1950, although it was not published until three years later.  The plot takes the reader on a violent journey through the jungle.  The novel is set during 1940s Guatemala, and its central themes are race and nationality. The Adventures of Twizzle is the first television show produced by AP Films and specifically Gerry Anderson, after being approached by author Roberta Leigh (who also co-produced with Anderson) and her colleague Suzanne Warner.  Sources vary as to who directed the series.  In addition to his production duties, Anderson also directed the episodes with photography by Arthur Provis, Anderson's founding partner at AP Films.  The music for the songs was written by Leslie Clair (a pseudonym for Leslie Solley) and scored by Barry Gray.  Art direction was by Reg Hill and special effects were by Derek Meddings, all of whom would become long-time collaborators of Anderson.  Twizzle, and all the puppets for the 52 episodes, were made by Joy Laurey.  There were two Twizzle puppets made for filming, one for conventional shots and the second for stunt shots when Twizzle's arms and legs became longer, a trick that relied on a system of curtain rings and puppet strings pulled inside the puppets' arms and legs. A Curtain of Green was the first collection of short stories written by Eudora Welty.  In these stories, Welty looks at the state of Mississippi through the eyes of its inhabitants, the common people, both black and white, and presents a realistic view of the racial relations that existed at the time.  Welty, though, looks past race, not overtly focusing on the subject, and sees Mississippi as what it is.  The stories subtly combine myth and reality to create portraits of odd, but undeniable, beauty.  One of the finest pieces in the collection is titled "A Worn Path."  Welty's skill as a writer perhaps reaches its finest point with this story of an aging woman who faces her greatest obstacle, the journey of life as she tries to cope with the grief from the death of her grandson she goes through a journey comparable to a Greek epic.  Full of challenges that she had to overcome while still keeping her dignity.  Welty writes "A Worn Path" to show the reader that even though they aren't an epic hero they can still have dignity in their life. The Baileys Women's Prize for Fiction (previously with sponsor names Orange Prize for Fiction (1996–2006 and 2009–12) and Orange Broadband Prize for Fiction (2007–08)) is one of the United Kingdom's most prestigious literary prizes.  It is awarded annually to a female author of any nationality for the best original full-length novel written in English and published in the United Kingdom in the preceding year. Apprentice Adept is a heptalogy of fantasy and science fiction novels written by English American author Piers Anthony.  The series takes place on "Phaze" and "Proton", two worlds occupying the same space in two different dimensional planes.  Phaze is a lush planet of magic, where Proton is a barren mining planet of science.  As the series opens, each person born on Phaze and Proton has an alternate self living on the other world.  But if a person on either world lacks a duplicate (for instance if a Proton citizen immigrated there from another planet, or a counterpart from the opposite frame died), he can cross to the other through an energy "curtain" that circumscribes each frame. "Why I Live at the P.O." is a short story written by Eudora Welty, American writer and photographer.  It was published in her collection of stories named "A Curtain of Green" (1941).  The work was inspired by a photograph taken by Welty that depicts a woman ironing at the back of a post office.  The story is classified as an example of Southern realism.  "Why I Live at the P.O." is one of Welty's most popular and frequently anthologized stories. Madeline is a media franchise that originated as a series of children's books written and illustrated by Ludwig Bemelmans, an Austrian author.  The books have been adapted into numerous formats, spawning telefilms, television series and a live action feature film.  The adaptations are famous for the closing line, a famous phrase Ethel Barrymore used to rebuff curtain calls, "That's all there is, there isn't any more."  The stories take place in a Catholic boarding school in Paris.  Much of the media start with the line "In an old house in Paris that was covered in vines, lived twelve little girls in two straight lines ..." The stories often are written entirely in rhyme, and include simple themes of daily life which appeal to children.
