TASK DEFINITION: In this task, you're given passages that contain mentions of names of people, places, or things. Some of these mentions refer to the same person, place, or thing. Your job is to write questions that evaluate one's understanding of such references. Good questions are expected to link pronouns (she, her, him, his, their, etc.) or other mentions to people, places, or things to which they may refer. Do not ask questions that can be answered correctly without understanding the paragraph or having multiple answers. Avoid questions that do not link phrases referring to the same entity. For each of your questions, the answer should be one or more phrases in the paragraph, and it should be unambiguous.
PROBLEM: Passage: A poacher hides from an unknown creature in his boat. While it breaks through the boat and attempts to catch the poacher, he commits suicide by shooting himself dead to prevent the beast from killing him.
Meanwhile while shooting a documentary about a long-lost indigenous tribe, the Shirishamas, on the Amazon River, director Terri Flores and members of her crew including cameraman Danny Rich, production manager Denise Kalberg, her boyfriend, sound engineer Gary Dixon, visionary Warren Westridge, anthropologist Professor Steven Cale, and boat skipper Mateo come across stranded Paraguayan snake hunter Paul Serone and help him, believing he knows how to find the tribe they are searching for.
Most of the crew are uncomfortable around Serone, and Cale clashes with him several times in regards to Shirishama lore. Later, while trying to free the boat's propeller from a rope, Cale is stung in the throat by a wasp inside his scuba regulator, which swells his throat shut and leaves him unconscious. Serone performs an emergency cricothyrotomy, seemingly saving Cale's life. With that, Serone takes command and captain of the boat and the crew. They are then forced to help him achieve his true task: hunting down and capturing a giant record-breaking female green anaconda he had been tracking the whole time.
Later, Mateo gets lost and is the first to be killed by the anaconda, which coils around him before it snaps his neck near the boat where the poacher had been killed. A photograph in an old newspaper reveals that Mateo, Serone, and the unnamed poacher were actually working together to catch animals, including snakes. The others try to find him while Gary sides with Serone, who promises if they help him find the anaconda, he will help them get out alive.

SOLUTION: Gary Dixon is a member of whose crew?

PROBLEM: Passage: Two days after the events of the first film, a traumatized and blood-covered Sarah escapes the cave with no memory of the events. She is taken to a hospital, where it is found that some of the blood on her belongs to Juno Kaplan. Sheriff Vaines takes his deputy Elen Rios, Sarah, and three spelunking specialists – Dan, Greg, and Cath – to the cave to find the missing women. The team members are sent down via an old mine shaft operated by the old, mysterious Ed Oswald.
The group discovers Rebecca's mutilated body, causing Sarah to have flashbacks of the crawlers and causing Vaines to believe Sarah may be responsible for the girls' disappearance.  While crawling through a tunnel, she attacks Vaines and the others, causing the others to split up. Vaines runs to search for Sarah, and in the process is surprised by a crawler, and fires his gun in a panic, causing a minor collapse in the cavern which traps Cath, separating her from Rios, Dan, and Greg.  The three decide to find an alternate way around in order to try to free Cath and arrive in a room full of bones, where they find Holly's video camera. They watch it and realize the women were attacked by the crawlers. The three are then themselves attacked by crawlers and separated.
Rios starts calling for help, alerting the crawlers to her location, but is rescued by Sarah.  The two then watch as a crawler kills Dan and drags his body away, prompting Sarah to inform Rios that the crawlers are blind and hunt via sound. After escaping from and killing a crawler, Cath finds Greg before the two escape from another crawler and find Sam's body. They decide to try to use her to swing across a chasm, but are attacked again. Greg sacrifices himself to buy time for Cath, but she ultimately does not survive.

SOLUTION: Who attacks someone, causing the group to split up?
