Task: Question Answering
Input (English): Passage: Two couples - Betty and Johnny (June Kenney and Robert Reed), and Jeanne and Pete (Joan Lora and Eugene Persson) - are vacationing at sea together. When the ship's captain passes out drunk, they decide to go to a nearby jungle island. As they depart, Capt. Tony awakens and calls out, warning them not to.
As they explore the island, Johnny falls into a pit. The others start pulling him out, but look up to see Dr. Balleau and two servants. Balleau orders the servants to help get Johnny out.
That night at his house, Balleau tells the couples that he moved to the island "after the war" to indulge his passion for hunting. Both couples want to leave, but Balleau says they can not because wild animals prowl the jungle. Ballaeu makes his wife Sandra show Betty and Jeanne to the guestroom, while Balleau's servant Jondor escorts Johnny and Pete to their room.
A bit later, Sandra and houseguest Dean Gerard, who are lovers, discuss Dean's latest plan for their escape. Meanwhile, Johnny and Pete go to Betty and Jeanne's room to talk about their situation. They decide to poke about the house. Betty and Johnny are stopped by Sandra and Dean, who take them back to the guestroom. Jeanne and Pete find a tunnel. They hide as a servant walks into a room. When he leaves, Jeanne and Pete go in and discover a vat of bubbling acid. They hide again when the servant returns and are horrified when he reveals a woman's body floating in an aquarium. The servant leaves again. Jeanne and Pete go back to the guestroom to tell the others what they have seen.
Dean tells them his escape plan. He and Sandra will slip out of the house, steal a boat, go to the mainland and then come back with help. But as they sneak through the front gate, Balleau, toting a spear, follows. 
Question: Who catches the man who fell into a pit poking around the house?
Output (English): Sandra.
