In this task, you're given a question, along with a context passage. The passage will not have a direct answer to the question, but can include some information and a clue for the answer. Assuming you can only obtain information about one entity in the passage, your job is to determine whether information from the passage can be used to answer the question. Indicate your choice as `a` for Yes or `b` for No.

Question: Who did Richard Brody write reviews for? Passage:Roger Ebert rated the film three-and-a-half stars, praising the creation of an island world that "might as well be ruled by Prospero". A devoted fan of Anderson, Richard Brody hailed Moonrise Kingdom as "a leap ahead, artistically and personally" for the director, for its "expressly transcendent theme" and its spiritual references to Noah's Ark. Peter Bradshaw of The Guardian gave the film four stars out of five, calling it "another sprightly confection of oddities, attractively eccentric, witty and strangely clothed". The New York Timess Manohla Dargis reviewed Anderson and Coppola's screenplay as a "beautifully coordinated admixture of droll humor, deadpan and slapstick". Peter Travers positively reviewed the actors' performances, calling Norton engaging, Balaban "delightful" and Willis agreeable. Travers also credited cinematographer Yeoman for "a poet's eye" and composer Alexandre Desplat for his contributions. As novice actors, Jared Gilman and Kara Hayward also received praise. The Daily Telegraphs review stated it was "exhilarating" to see different elements combined, such as the music of Britten and Hank Williams. It called the end result "an extraordinarily affected piece of filmmaking". The Hollywood Reporters review by Todd McCarthy described the film as an "eccentric, pubescent love story", "impeccably made". For Empire, Nev Pierce declared it "a delightful film of innocence lost and regained". Christopher Orr of The Atlantic wrote that Moonrise Kingdom was "Anderson's best live-action feature" and that it "captures the texture of childhood summers, the sense of having a limited amount of time in which to do unlimited things". Kristen M. Jones of Film Comment wrote that the film "has a spontaneity and yearning that lend an easy comic rhythm", but it also has a "rapt quality, as if we are viewing the events through Suzy's binoculars or reading the story under the covers by a flashlight".

Question: Which of the companies involved with the three-dimensional integrated circuit was founded first? Passage:In 1986, Mitsubishi Electric researchers Yoichi Akasaka and Tadashi Nishimura laid out the basic concepts and proposed technologies for 3D ICs. The following year, a Mitsubishi research team including Nishimura, Akasaka and Osaka University graduate Yasuo Inoue fabricated an image signal processor (ISP) on a 3D IC, with an array of photosensors, CMOS A-to-D converters, arithmetic logic units (ALU) and shift registers arranged in a three-layer structure. In 1989, an NEC research team led by Yoshihiro Hayashi fabricated a 3D IC with a four-layer structure using laser beam crystallisation. In 1990, a Matsushita research team including K. Yamazaki, Y. Itoh and A. Wada fabricated a parallel image signal processor on a four-layer 3D IC, with SOI (silicon-on-insulator) layers formed by laser recrystallization, and the four layers consisting of an optical sensor, level detector, memory and ALU.

Question: How many times have Dean Malenko and Gedo fought each other? Passage:The Great Sasuke and Wild Pegasus received byes in the first round. The opening match of the event featured Dean Malenko against Gedo. Both men countered each other with various submission moves until Gedo raked Malenko's eyes and hit him headbutts but Malenko whipped him in the corner and executed a suplex powerslam. Both men performed another series of submission moves until Malenko attempted to hit a kneeling reverse piledriver on Gedo but Gedo countered by hitting a kneeling reverse piledriver of his own. He then applied a STF on Malenko until Malenko crawled to the ropes and caught the ropes forcing Gedo to break the hold. Gedo then attempted a diving headbutt on Malenko but Malenko caught him by hitting a lariat to a diving Gedo in the head to gain a near-fall. Malenko followed with a diving crossbody for another near-fall. He then dashed off the ropes and Gedo executed a Powerslam for the win.
