Task: Question Answering
Input (English): Passage: Dr. Lawrence Angelo works for Virtual Space Industries, running experiments in increasing the intelligence of chimpanzees using drugs and virtual reality. One of the chimps escapes using the warfare tactics for which he was being trained.  Dr. Angelo is generally a pacifist, who would rather explore the intelligence-enhancing potential of his research without applying it for military purposes. His wife Caroline is unhappy with the way he is ignoring her to focus on this project.
Jobe Smith, a local greenskeeper with an intellectual disability, lives in the garden shed owned by the local priest, Father Francis McKeen. McKeen's brother, Terry, is a local landscape gardener and employs Jobe to help him with odd jobs. Father McKeen punishes the challenged Jobe with a belt and "Hail Marys" whenever he fails to complete his chores.
Dr. Angelo realizes he needs a human subject to work with, and he spots Jobe mowing his lawn.  Peter Parkette, Dr. Angelo's young  neighbor, is friends with Jobe. Dr. Angelo invites both of them over to play some virtual reality games. Learning more about Jobe, Angelo persuades him to participate in his experiments, letting him know it will make him smarter. Jobe agrees and begins the program. Dr. Angelo makes it a point to redesign all the intelligence-boosting treatments without the "aggression factors" used in the chimpanzee experiments.
Jobe soon becomes smarter, for example, learning Latin in only two hours. Meanwhile, Jobe also begins a sexual relationship with a young rich widow, Marnie. However, Jobe begins to display telepathic abilities and has hallucinations. He continues training at the lab, until an accident makes Dr. Angelo shut the program down. The project director, Sebastian Timms, employed by a mysterious agency known as The Shop, keeps tabs on the progress of the experiment, and discreetly swaps Dr. Angelo's new medications with the old Project 5 supply (reintroducing the "aggression factors" into the treatment). 
Question: What is the last name of the person Lawrence persuades to participate in his experiments?
Output (English): Smith.
