Task: Question Answering
Input (English): Passage: Engineers George Melton and Allan Chadwick work furiously to complete a design on time, even though it is Christmas Eve. Michael O'Brien, the third partner in the firm, arrives with presents for all and kindly lets their employees leave. The three old men then go home to the mansion they share with Madame Tanya, an elderly countess dispossessed by the Russian Revolution, for a dinner with prestigious guests.
When the guests cancel at the last minute, George is convinced it is because of his dark past. To relieve George's black mood, Michael comes up with an idea to obtain new guests for dinner. Each man throws out a wallet containing $10 and his business card into the street. George's is found by Arlene Terry, who merely gives the money to her driver and discards the wallet. However, the other two are returned by more considerate people: Texas cowboy James Houston and teacher Jean Lawrence. They stay for dinner and soon become good friends with the three men and Madame Tanya. James and Jean also fall in love with each other, delighting the three men.
When the engineers have to travel to another city on business, Madame Tanya begs Michael to take the train rather than fly. He assures her it is perfectly safe, but Madame Tanya's premonition proves tragically correct when their aircraft crashes in a storm, killing all three. When James and Jean come to announce that they are engaged, they receive the bad news. The ghosts of the three men return home, where they are dimly sensed by Madame Tanya. 
Question: What are the first names of the people who were killed?
Output (English): Michael.
