Please answer the following question: I am a movie director and I just received the following movie plot. Could you help me answer this question? If not, let me know by writing "Not answerable". Plot title: The Island Movie plot: In the year 2019, Lincoln Six Echo and Jordan Two Delta live with others in an isolated compound. Their community is governed by a set of strict rules. The residents believe the outer world has become too contaminated for human life with the exception of one contagion-free island. Every week, a lottery is conducted and the winner gets to leave the compound to live on the island. Lincoln begins having dreams that he knows are not from his own experiences. Dr. Merrick, a scientist who runs the compound, is concerned and places probes in Lincoln's body to monitor his cerebral activity. While secretly visiting an off-limits power facility in the basement where his friend, technician James McCord, works, Lincoln discovers a live moth in a ventilation shaft, leading him to deduce the outside world is not really contaminated. Lincoln follows the moth to another section, where he discovers the "lottery" is actually a disguise to remove inhabitants from the compound, where the "winner" is then used for organ harvesting, surrogate motherhood, and other purposes for each one's sponsor, who is identical to them in appearance. Merrick learns Lincoln has discovered the truth, which forces Lincoln to escape. Meanwhile, Jordan has been selected for the island. Lincoln and Jordan escape the facility, where they emerge in an Arizona desert. Lincoln explains the truth to her, and they set out to discover the real world. Merrick hires Burkinabe mercenary Albert Laurent to find and return them unharmed to the compound. Lincoln and Jordan find McCord, who explains that all the facility residents are clones of wealthy and/or desperate sponsors, who are kept ignorant about the real world and conditioned to never question their environment or history. McCord provides the name of Lincoln's sponsor in Los Angeles, and helps them to the Yucca railway station, before mercenaries kill him. Jordan's sponsor, model Sarah Jordan, is comatose following a car accident and requires transplants from Jordan to survive. Lincoln's sponsor, Tom... My question: Merrick realizes that what is responsible for Lincoln's memories and behavior?
A:
A cloning defect.
