Question: Who is the oldest band that Eric listens to? Passage:Eric is a well-known fan of science fiction, such as and especially Star Wars, in which he compares himself to Luke Skywalker. He is also known to have a large, beloved collection of G.I. Joe. He listens to artists such as Led Zeppelin, KISS, Aerosmith, Pink Floyd, Lynyrd Skynyrd, Deep Purple, Queen, Styx and Rush. He is also a Beatles fan and has been known to liken his group of friends to them, accusing Jackie of "breaking up the band" with her romantic entanglements with Kelso and Hyde (calling her Yoko, in reference to Yoko Ono). It is also hinted that he is both a Batman and Spider-Man fan, having Spider-Man bed sheets and a considerable number of comic books, most of them bearing the Marvel Comics logo with the titular character on the covers. When he fights a fan at the Packers game, he tells Red that he learned his moves from Spider-Man; coincidentally, Topher Grace starred as Eddie Brock, a character who obtains powers very similar to Spider-Man, thus transforming him into the monstrous Venom in Spider-Man 3 in 2007.

Question: Who created the character with whom the goddess Bast made her first appearance in Fantastic Four #52? Passage:Characters based on ancient Egyptian deities were first mentioned in Captain America Comics #20 (November 1942), published by Marvel Comics' predecessor Timely Comics, in which Captain America and Bucky investigate the murder of Colonel Fitzpatrick, who was studying the Book of Thoth while stationed in Egypt. The Heliopolitans first full Golden Age appearance was in the story "The Terror That Creeps" by Stan Lee and Werner Roth, published in Marvel Tales #96 (June 1950), and involves a man that fails to convince the public that the Great Sphinx of Giza is slowly moving to the edge of the desert, where it will be empowered by Set and destroy mankind. The goddess Bast would later make her first appearance (as a totem) with the Black Panther in Fantastic Four #52 (July 1966). Many of the other deities, including Horus, Isis and Osiris, were introduced in Thor #239 (September 1975). Khonshu, who became associated with Moon Knight, first appeared in Moon Knight #1 (November 1980). Joseph Muszynski argued in his book Everything I Needed to Know About Life I Learned from Marvel Comics that the introduction of Egyptian deities "excited our tendency to enjoy variety" as the pantheon contained multiple gods and personalities as opposed to the Judeo-Christian religions. Ed Strauss contended that Marvel was able to dive into ancient Egyptian religion because it "had long been retired into the realm of mythology" unlike Christianity.

Question: Did Bess Truman live longer than her husband Harry S. Truman? Passage:Ferrell's biography follows the course of Truman's life from his birth in 1884 in Lamar, Missouri to his 1972 death and burial at the Truman Library in Independence. The first five chapters examine his service as a captain in World War I, his pre-politics careers in banking, farming, and a failed run as a haberdasher which ended in bankruptcy, and marriage to Bess Truman in 1919. Chapters six to eight look at his early political career, launched by Kansas City boss Tom Pendergast, beginning with his election as a county judge in 1922, then senator in 1934, and in 1944, vice president to Franklin Roosevelt, in a behind-the-scenes compromise Ferrell calls "the most extraordinary political arrangement of the present century"Democratic Party leaders could see that the extremely ill Roosevelt was unlikely to survive his fourth term in office, and had to convince him to drop then-VP Henry Wallace in favor of Truman, who was felt to be a more "reliable" man. Truman ascended to the presidency upon Roosevelt's death in 1945, and this period in Truman's life is covered in chapters nine to 17the majority of the bookincluding Truman's decision to detonate atomic weapons on Hiroshima and Nagasaki to force an end to World War Two, his unexpectedly successful reelection in 1948, his civil-rights initiatives, and his administration's handling of foreign-policy issues, most prominently the Korean War.
