Question: Are Robin McKinley and Primo Levi both authors ? 
Context: The Truce (Italian: "La Tregua" ) is a 1997 film directed by Francesco Rosi, written by Tonino Guerra, based on Primo Levi's memoir, "The Truce".  The film deals with Primo Levi's experiences returning to Italy in 1945 after the Red Army liberated the concentration camp at Auschwitz during the Second World War.  This was Rosi's final film before his death in 2015. Primo Michele Levi (] ; 31 July 1919 – 11 April 1987) was an Italian Jewish chemist, writer, and Holocaust survivor.  He was the author of several books, novels, collections of short stories, essays, and poems.  His best-known works include "If This Is a Man" (1947) (U.S.: "Survival in Auschwitz"), his account of the year he spent as a prisoner in the Auschwitz concentration camp in Nazi-occupied Poland; and his unique work, "The Periodic Table" (1975), linked to qualities of the elements, which the Royal Institution of Great Britain named the best science book ever written. Giovanni Palatucci (31 May 1909 – 10 February 1945) was an Italian police official who was long believed to have saved thousands of Jews in Fiume between 1939 and 1944 (current Rijeka in Croatia) from being deported to Nazi extermination camps.  In 2013 a research panel of historians led by the "Centro Primo Levi" reviewed almost 700 documents and concluded that Palatucci had followed RSI and German orders concerning the Jews and enabling the deportation of the majority of the 570 Jews living in Fiume and surrounding areas, 412 of whom were deported to Auschwitz, a higher percentage than in any Italian city.  The matter is currently the topic of scholarly debate.  A national commission of historians recommended by the Union of the Italian Jewish Communities, the Center for Contemporary Jewish Documentation in Milan, the Italian Ministry of the Interior and the Centro Primo Levi NY is conducting a comprehensive review of the documents. The Outlaws of Sherwood is a retelling of the legend of Robin Hood by Robin McKinley.  In McKinley's afterword, she says, "The retellings through the centuries have echoed concurrent preoccupations."  The story includes both the traditional Robin Hood characters — Little John, Much, Friar Tuck, Marian and Alan-a-dale — and characters of McKinley's own invention.  Notably, three of the most important characters are women, all of whom escape marriage to prospective spouses chosen by their fathers. Shop Talk: A Writer and His Colleagues and Their Work is a collection of previously published interviews with important 20th-century writers by novelist Philip Roth.  Among the writers interviewed are Primo Levi, Aharon Appelfeld, Ivan Klima, Isaac Bashevis Singer, Milan Kundera, and Edna O'Brien.  In addition, the book contains a discussion with Mary McCarthy about Roth's novel "The Counterlife" and a "New Yorker" essay on Saul Bellow.  Roth's trip to Israel to interview Appelfeld inspired his novel "Operation Shylock". A Tranquil Star: Unpublished Stories of Primo Levi is a 2007 anthology of short stories by the Italian writer Primo Levi.  Released 20 years after Levi's death, the book consists of seventeen stories previously unpublished in English.  The stories were translated by Ann Goldstein, an editor at "The New Yorker" and Alessandra Bastagli, an editor at Palgrave Macmillan. The Black Hole of Auschwitz is a collection of essays by the Italian author Primo Levi.  Originally published under the Italian title "Asymmetry and Life" it has two distinct halves.  The first half, "The Black Hole of Auschwitz" is a collection of essays, often prefaces to other books, which make a plea against holocaust denial.  The second half "Other People's Trades" are a mixture of essays on a wide variety of subjects.  All of these works were collected together in the production of Levi's Italian anthology of works "Opere" in 1997. Jennifer Carolyn Robin McKinley (born November 16, 1952), known as Robin McKinley, is an American author of fantasy and children's books.  Her 1984 novel "The Hero and the Crown" won the Newbery Medal as the year's best new American children's book. On 19 October 2006, the Royal Institution of Great Britain named "The Periodic Table", by Primo Levi, the best science book ever.  After taking nominations from many scientists in various disciplines, authors, and other notable people (such as the Archbishop of Canterbury), the Royal Institution compiled a shortlist of books for consideration.  This shortlist was presented to the public at an event held at Imperial College and the audience voted to determine which book was "the best." The Drowned and the Saved (Italian: "I sommersi e i salvati" ) is a book of essays on life in the Nazi extermination camps by Italian-Jewish author and Holocaust survivor Primo Levi, drawing on his personal experience as a survivor of Auschwitz (Monowitz).
