In this task, you are given a question and a context passage. You have to answer the question based on the given passage.

Example Input: What was the main job for one of the individuals who was one of the final Apollo astronauts to go to the moon?, Context: The Apollo astronauts were chosen from the Project Mercury and Gemini veterans, plus from two later astronaut groups. All missions were commanded by Gemini or Mercury veterans. Crews on all development flights (except the Earth orbit CSM development flights) through the first two landings on Apollo 11 and Apollo 12, included at least two (sometimes three) Gemini veterans. Dr. Harrison Schmitt, a geologist, was the first NASA scientist astronaut to fly in space, and landed on the Moon on the last mission, Apollo 17. Schmitt participated in the lunar geology training of all of the Apollo landing crews.
Example Output: geologist

Example Input: How bad were Nasser's heart attacks?, Context: Nasser had few personal vices other than chain smoking. He maintained 18-hour workdays and rarely took time off for vacations. The combination of smoking and working long hours contributed to his poor health. He was diagnosed with diabetes in the early 1960s and by the time of his death in 1970, he also had arteriosclerosis, heart disease, and high blood pressure. He suffered two major heart attacks (in 1966 and 1969), and was on bed rest for six weeks after the second episode. State media reported that Nasser's absence from the public view at that time was a result of influenza.
Example Output: major heart attacks

Example Input: Exactly how big was the mosaic?, Context: The great Navicella mosaic (1305–1313) in the atrium of the Old St. Peter's is attributed to Giotto di Bondone. The giant mosaic, commissioned by Cardinal Jacopo Stefaneschi, was originally situated on the eastern porch of the old basilica and occupied the whole wall above the entrance arcade facing the courtyard. It depicted St. Peter walking on the waters. This extraordinary work was mainly destroyed during the construction of the new St. Peter's in the 17th century. Navicella means "little ship" referring to the large boat which dominated the scene, and whose sail, filled by the storm, loomed over the horizon. Such a natural representation of a seascape was known only from ancient works of art.
Example Output:
occupied the whole wall above the entrance arcade facing the courtyard
