Task: Question Generation
Input (English): Passage: Hotshot ensign Alan Drake, fresh from the flying academy at Pensacola, Florida, gets off to a bad start with the pilots of an elite squadron, nicknamed the "Hellcats", to which he has been posted in San Diego. Making a nearly disastrous landing attempt in heavy fog against orders and disqualifying the squadron during a competitive shooting exercise by colliding with the target drogue does not endear him to his fellow pilots. He also asks out a woman he has met, Lorna, not knowing that she is the squadron commander Billy Gary's (Walter Pidgeon) wife.
However, Drake is earnest and contrite. He mixes with the Hellcats at the Garys' large house, which the sociable couple have opened as an unofficial officers' club. His flying and his social errors are forgiven, and his fellow pilots accept him, nicknaming him "Pensacola". 
Drake further proves himself when he helps Lieutenant Jerry Banning solve a problem in a blind-landing apparatus he is developing. Just after Commander Gary is sent out of town on assignment, Banning decides the apparatus is ready to test in fog — but it fails and Banning is killed. Working with Banning's assistant, Drake soon identifies the problem, but no further testing is allowed until Commander Gary's return.
Banning had been a childhood friend of Lorna Gary, and is not her first friend to die. She sinks into a deep depression. She also knows that Gary will expect her to hide her feelings and carry on, something that is very much not in her nature. Drake, appreciating the help the Garys gave him when he arrived, visits her at her home, and convinces her she should not suffer alone. They go for walks, drives, and tennis; he amuses her with jokes. Finally, at a restaurant she reaches for his hand and in doing so realizes she is falling for him. She quickly breaks away, and says she cannot see him any more.
Output (English): What is the last name of the person who amuses Lorna with jokes?
