Task: Question Answering
Input (English): Passage: Idaho police officer Hal Jackson arrives at the funeral for young Frank Dixon, Jr., who has died in a car accident. Hal, a friend of the Dixon family, does not go inside, feeling it would be too difficult to take. Hal finds it hard to believe that, only a few days ago, the Dixons were a relatively regular family. In flashback, he recounts what led to Frank Jr.'s death. Frank Jr. has returned home for the summer to aid his father, Frank Sr. (Harold Agee), on the family farm. He also visits his girlfriend Betty Hutchins. When Frank Sr.'s new tractor arrives at the local train station, Frank Jr.'s brother Alan wishes to drive it, having recently taken a driver's test. His father disallows it, so Frank Jr. drives it home.
The next day, Alan discovers that his license has arrived in the mail. Ecstatic, he wishes to drive immediately, asking his family members if they need help with any errands. Later, Hal shows up at the Dixon home. Knowing that Alan's license had been scheduled to arrive, he begins to talk to Alan, telling him about things he should know in order to be able to drive safely. As he finishes giving the advice, Frank Jr. and Betty return home. Alan asks his father if he can drive the car into town. His father lets him, and Frank Jr. and Betty agree to go with him to make sure he arrives safely. 
Question: Who does the police officer instruct about safe driving?
Output (English): Alan.
