Example Input: Question: Who is the oldest person recruited to join Demon Hunter? Passage:In 2003 they took a short break, during which McCaddon decided to leave Society's Finest, and went on to join Demon Hunter. After leaving Society's Finest and Embodyment, Ryan Clark and Don Clark, formerly of Training for Utopia, recruited him, Jesse Sprinkle, formerly of Poor Old Lu, and Jon Dunn (Who would later join Soul Embraced) to join their project, Demon Hunter. Demon Hunter already had an album before he joined. On this album McCaddon had contributed by photography. On his Demon Hunter debut, Summer of Darkness, was great success. In 2005, Ethan Luck, formerly of The O.C. Supertones and Project 86, replaced McCaddon. In 2006, former Embodyment members, Mark Garza (drums) and Andrew Godwin (guitar), contacted McCaddon and said they wanted to play metal again. McCaddon contacted former Society's Finest member, Nick Nowell (bass) and asked him to join their new project, The Famine. Though McCaddon knew people would compare the Famine to Embodyment, he stated that "We started The Famine because we wanted to get away from the stuff we were playing with Embodyment...".

Example Input: Question: When did construction begin on the Space Station launched in the 1970's based on a design of the Saturn IB S-IVB upper stage called Skylab A? Passage:In the 1970s, the Skylab Space Station is launched, but apparently as a wet workshop design that is based on the Saturn IB S-IVB upper stage called Skylab A. The Saturn V that might have launched Skylab in our timeline instead launches Skylab B, a lunar orbit space station unofficially named "Moonlab", also a wet workshop based on the S-IVB. The Apollo-Soyuz Test Project is instead a series of visits by the Apollo Command/Service Module to Salyut space stations, and Soyuz missions to both Skylab and Moonlab. To facilitate the latter, the Soviets finally finish work on their N-1. The Skylab/Moonlab programs lead to improvements in the design of the Apollo Command/Service Module. A Block III CSM is produced using battery power in place of fuel cells, followed by the Block IV and V, which have a degree of reusability (modular construction and resistance to salt water corrosion). Also chronicled is the development of the experimental 'Mars Excursion Module' by small aerospace firm Columbia Aviation as it struggles against larger rival contractors of NASA and its engineers working painstakingly against the technical challenges of a working and reliable Mars lander.
