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.

Q: Passage: A tsunami is an unusual form of wave caused by an infrequent powerful event such as an underwater earthquake or landslide, a meteorite impact, a volcanic eruption or a collapse of land into the sea. These events can temporarily lift or lower the surface of the sea in the affected area, usually by a few feet. The potential energy of the displaced seawater is turned into kinetic energy, creating a shallow wave, a tsunami, radiating outwards at a velocity proportional to the square root of the depth of the water and which therefore travels much faster in the open ocean than on a continental shelf. In the deep open sea, tsunamis have wavelengths of around 80 to 300 miles (130 to 480 km), travel at speeds of over 600 miles per hour (970 km/hr) and usually have a height of less than three feet, so they often pass unnoticed at this stage. In contrast, ocean surface waves caused by winds have wavelengths of a few hundred feet, travel at up to 65 miles per hour (105 km/h) and are up to 45 feet (14 metres) high.A trigger event on the continental shelf may cause a local tsunami on the land side and a distant tsunami that travels out across the ocean. The energy of the wave is dissipated only gradually, but is spread out over the wave front, so as the wave radiates away from the source, the front gets longer and the average energy reduces, so distant shores will, on average, be hit by weaker waves. However, as the speed of the wave is controlled by the water depth, it does not travel at the same speed in all directions, and this affects the direction of the wave front - an effect known as refraction - which can focus the strength of the advancing tsunami on some areas and weaken it in others according to undersea topography.
As a tsunami moves into shallower water its speed decreases, its wavelength shortens and its amplitude increases enormously, behaving in the same way as a wind-generated wave in shallow water, but on a vastly greater scale.  Either the trough or the crest of a tsunami can arrive at the coast first. In the former case, the sea draws back and leaves subtidal areas close to the shore exposed which provides a useful warning for people on land. When the crest arrives, it does not usually break but rushes inland, flooding all in its path. Much of the destruction may be caused by the flood water draining back into the sea after the tsunami has struck, dragging debris and people with it. Often several tsunami are caused by a single geological event and arrive at intervals of between eight minutes and two hours. The first wave to arrive on shore may not be the biggest or most destructive.  Occasionally, a tsunami may transform into a bore, typically in a shallow bay or an estuary.

A: What two types of tsunami's can a trigger event on the continental shelf cause?

Q: Passage: A suicidal woman, Lillian Belton, unsuccessfully attempts suicide by taking pills, and she is referred to a psychiatrist for therapy. While at the psychiatrist, Lillian attempts suicide again by trying to jump out the window, and she is only stopped by the psychiatrist, Dr. Mary White. Dr. White learns that Lillian's troubles are connected to Jack Kerry, (Louis Hayward) who she contacted just prior to her attempt with the psychiatrist. Lillian loves Jack, but he is an alcoholic and does not love Lillian the way she loves him. Dr. White contacts Jack, and persuades him to seek treatment for his alcoholism. As Jack completes his treatment, he falls in love with Dr. White, but the Dr. reminds Jack of Lillian's need for him, and Jack and Lillian marry. Lillian's physician, Dr. Gordon Phillips, is also in love with Dr. White, but cannot convince her to leave her patients and her practice. Dr. White encounters Lillian and Jack at a costume ball, and Jack manages to get a dance with Dr. White, as a suspicious Lillian looks on. Jack confesses his love for Dr. White, but she again reminds him of his marriage and commitment to Lillian. An enraged Lillian creates a scene with Dr, White, who uses this experience as a parallel of her and Dr. Phillips' relationship.

A: What is the first name of the person who is referred to a psychiatrist for therapy?

Q: Passage: Helen and Jackson live together in New York City. At the beginning of the film, the two are driving towards the Kentucky farmhouse, Kilronan, where Jackson grew up, primarily to introduce Helen to Jackson's mother, Martha.
After returning to New York, Helen discovers she is pregnant. When she informs Jackson of this, he asks her to marry him and she accepts. The wedding is held at Kilronan, where Helen meets Jackson's paternal grandmother, Alice, who tells Helen she doesn't trust Martha.
After returning to New York apartment, Helen is assaulted by a man who steals her locket. When Helen says she's pregnant, he cuts her abdomen and leaves. The fetus was not injured.
Martha arrives and says she wants to sell Kilronan because she cannot run it alone. Helen tells Jackson she wants to move to Kentucky and in with Martha for a year and help renovate the land. Jackson tells Helen his father died in that house when he was seven and he blames himself because he ran into his father pushing him down the stairs. Jackson also tells Helen that his father had been cheating on Martha with Robin Hayes. Helen says they should go back so Jackson can face his "old ghosts".
The couple move in with Martha who attempts to divide the couple. Suspicious, Helen talks to Alice who tells her that Jackson is wrong about his father's death. The father landed on a nail puller at the bottom of the stairs, crushing his sternum, which, according to news reports was a freak accident.
Helen tells Jackson that Martha is tearing their marriage apart. He agrees to go back to New York and tells his mother.
That evening, Martha bakes a cake for Helen laced with pitocin, a labor inducer. Helen wakes up the next morning, feeling strange. She discovers a baby room set up by Martha and finds the locket that was stolen from her in New York. When Martha unexpectedly enters the room, Helen tries unsuccessfully to escape.

A:
What is the name of the person who blames himself for his father's death?
