Task: Question Answering
Input (English): Passage: Old Mother Riley is sacked from her job as a step cleaner at the office where her daughter Kitty works. She goes home to make steak and kidney pudding for their lodger, Joe, who is vaguely engaged to Kitty, but distractedly pours castor oil into the gravy, with amusing results. Jo is not sure he wants to be tied down to Kitty (or her impossible mother) and arranges for his travel agency employers to post him to Paris for six months, much to Kitty's discomfiture. While changing a light bulb, Old Mother Riley has a fall from a stepladder, resulting in her hospitalisation: keen to claim the maximum amount on her insurance she alters her medical records for the worse, only to be carried off for an emergency operation when the doctors see how much appears to be "wrong" with her. However, the ruse works: just as bailiffs are arriving to remove all Old Mother Riley's furniture, her insurance agent arrives with £250 in cash, which she uses to pay off her rental arrears and treat Kitty and herself to an air flight to Paris, in order to check up on Joe, who has meanwhile become involved with a suspicious young Parisian lady (really a spy with code name "Madame Zero", who believes he is an English agent). 
Question: Who was their travel agency employers post them in Paris?
Output (English): Jo.
