A research project carried out by a team of training specialists from the U.S. Customs and Border Protection (CBP) required the identification of all tasks performed by Border Patrol Agents (BPAs). The team then recommended the level of training at which each task would be taught -- either the Basic or the Advanced level. Based on the team's recommendation, how to transport aliens in custody is now being taught in only Basic training. From the information given above, it can be validly concluded that A) if a BPA is in Advanced training, then the agent is taught material that does not include how to transport aliens in custody B) if a BPA is not in Basic training, the agent is taught how to transport aliens in custody C) if a BPA is taught how to transport aliens in custody, that agent is in Advanced training D) a BPA is in Basic training if the agent is taught material that does not include how to transport aliens in custody E) if a BPA is in Basic training, the agent is not taught how to transport aliens in custody
