Input: Consider Input: Question: When was the Bronze age? Passage:It was first studied by Lorraine Copeland and Peter Wescombe in 19651966. A wide variety of materials were recovered from the site and its immediate area that are now held in the Saint Joseph University in Beirut. Stone tools from the surface included numerous short, wide, sickle blades with fine denticulation or nibbling along with tanged arrowheads, scrapers, chisels, axes, burins, obsidian and a small green stone axe. Pottery resembled middle periods at Byblos and coloured similar to at Ard Tlaili with red or black washes. Both fine and coarse shards were found of jars with a variety of collared and flared necks and flat bases along with bow rims such as those found at Jericho. Vessels were decorated with stabbed and incised designs, finger pressed around the rim and smoothed by hand or with straw. A painted lattice pattern was detected on at least one piece. Comparisons were made with middle and late Neolithic periods at Byblos showing inhabitation from several phases. The site was also used in Bronze Age and Classical times and material from these phases has been found over a wide area around the site.

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".
