Input: Consider Input: Question: What is the location of the headquarters for the company that makes 3M tape? Passage:Surgical tape or medical tape is a type of pressure-sensitive adhesive tape used in medicine and first aid to hold a bandage or other dressing onto a wound. These tapes usually have a hypoallergenic adhesive which is designed to hold firmly onto skin, dressing materials, and underlying layers of tape, but to remove easily without damaging the skin. They allow air to reach the skin ("breathable"). Some breathable tapes such as Kinesiology Tape, and other elastic bandages with adhesive are made of cotton. Surgical tape is often white because it contains zinc oxide, which is added to help prevent infections. Tapes made of microporous material, such as 3M Micropore, are widely used.

Input: Consider Input: Question: How old was Derow's teacher and lasting influence at Oxford when Derow graduated from Oxford? Passage:Born in Newport, Rhode Island, Derow obtained his secondary education at The Roxbury Latin School in West Roxbury, Massachusetts. After an A.B. degree at Amherst (with Peter K. Marshall), he read for Greats as a second B.A. degree at Oxford in 1965–1967, achieving a First. At Oxford he was taught by, among others, W. G. (George) Forrest, who was a lasting influence. He completed a Ph.D. at Princeton on 'Rome and the Greek world from the earliest contacts to the end of the first Illyrian war', for which Professor J. V. A. Fine was his Advisor; in the preface to that work, he acknowledges the additional inspiration he had drawn from T. J. Luce and the historian and epigrapher C. Bradford Welles. After a spell of teaching at the University of Toronto, he returned to succeed Forrest at Wadham in 1977 when the latter was elected to the Wykeham Professorship of Ancient History at New College. In 2002–2005 Derow was also Director of Graduate Studies in ancient history for the Oxford Faculty of Classics.

Input: Consider Input: Question: When did Flygirl first make her appearance in the comic books? Passage:The popularity of DC's and Marvel's Silver Age superhero titles led Archie Comics to revive their own line of superhero comics. The Archie Adventure line began with titles centered on The Fly, The Jaguar, and a superheroic/spy version of the 1930s pulp character The Shadow. After suggestions and fan-art began suggesting a team made up of the characters published by Archie Comics precursor MLJ in the 1940s, Archie's superhero imprint, soon retitled Mighty Comics, re-introduced many of these characters, and brought them together in several issues of Fly Man. This team, which followed the success of The Avengers and the Justice League of America, was made up of The Shield, The Fly (re-dubbed Fly-Man), The Black Hood, and The Comet. Calling themselves The Mighty Crusaders, they initially came together as part of a plan by The Fly's nemesis The Spider to trap the hero. After appearing as a team for two more issues of Fly Man, and gaining Flygirl as a member in the process, they spun off into their own series, The Mighty Crusaders, which ran bimonthly for 7 issues. The Archie series mixed typical superhero fare with high camp. Don Markstein writes that they touched on "all the genre's cliches of the time", with Siegel's writing on the book being a "hokey rendition of Stan Lee".
