Task: Question Answering
Input (English): Passage: Jefferson Reed is a mild-mannered school teacher in Washington, D.C. His neighborhood is terrorized by a local gang called The Golden Lords, led by  Simon Caine and allied with drug lord Anthony Byers. One night, Jeff steps in to rescue a woman from the gang only to end up running from them himself. Hiding in a garbage dumpster, he manages to escape. As he climbs out, he is struck down by a glowing, green meteorite. His spine is crushed and he receives severe burns. A small fragment of the meteor was left over and taken by a vagrant named Marvin. Reed awakens several days later in the hospital, but when his bandages are taken off, he is miraculously healed of all injuries.
Jeff soon discovered that the meteorite had left him with spectacular abilities such as flight, x-ray/laser vision, superhuman strength, speed, and hearing, invulnerability, healing powers, the ability to absorb a book's content by touch, super breath, telepathy with dogs (which he uses to communicate with his own dog, Ellington), and telekinesis. Confiding this to his parents Ted and Maxine, they convince him to use his powers to help the community. His mother designs a costume and as the Meteor Man, he takes on the Golden Lords. He shuts down 15 crack houses, stops 11 robberies, brings peace between the police, the Crips, and the Bloods where they begin to work together to rebuild the community they destroyed, and plants a giant garden in the middle of the ghetto. 
Question: What causes Jefferson to receive severe burns?
Output (English): meteorite.
