Question: A Curtain of Green was written by the author of what nationality?

<P0-S0> Eudora Alice Welty (April 13, 1909 – July 23, 2001) was an American short story writer and novelist who wrote about the American South. <P0-S1>  Her novel "The Optimist's Daughter" won the Pulitzer Prize in 1973. <P0-S2>  Welty was awarded the Presidential Medal of Freedom, among numerous awards including the Order of the South. <P0-S3>  She was the first living author to have her works published by the Library of America. <P0-S4>  Her house in Jackson, Mississippi has been designated as a National Historic Landmark and is open to the public as a house museum. <SEP> <P1-S0> 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. <P1-S1>  Sources vary as to who directed the series. <P1-S2>  In addition to his production duties, Anderson also directed the episodes with photography by Arthur Provis, Anderson's founding partner at AP Films. <P1-S3>  The music for the songs was written by Leslie Clair (a pseudonym for Leslie Solley) and scored by Barry Gray. <P1-S4>  Art direction was by Reg Hill and special effects were by Derek Meddings, all of whom would become long-time collaborators of Anderson. <P1-S5>  Twizzle, and all the puppets for the 52 episodes, were made by Joy Laurey. <P1-S6>  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. <SEP> <P2-S0> A Curtain of Green was the first collection of short stories written by Eudora Welty. <P2-S1>  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. <P2-S2>  Welty, though, looks past race, not overtly focusing on the subject, and sees Mississippi as what it is. <P2-S3>  The stories subtly combine myth and reality to create portraits of odd, but undeniable, beauty. <P2-S4>  One of the finest pieces in the collection is titled "A Worn Path." <P2-S5>  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. <P2-S6>  Full of challenges that she had to overcome while still keeping her dignity. <P2-S7>  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. <SEP> <P3-S0> "Why I Live at the P.O." is a short story written by Eudora Welty, American writer and photographer. <P3-S1>  It was published in her collection of stories named "A Curtain of Green" (1941). <P3-S2>  The work was inspired by a photograph taken by Welty that depicts a woman ironing at the back of a post office. <P3-S3>  The story is classified as an example of Southern realism. <P3-S4>  "Why I Live at the P.O." is one of Welty's most popular and frequently anthologized stories.
