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: Famous Hollywood actor Don Bolton is a vain movie star whose biggest fear is to be drafted into the US Army. He definitely lacks the qualities of a good soldier, and he is so afraid of loud noise that he would not last a day in the service, let alone cope with hearing a single gunshot when he is on set shooting a war film at the studio. Colonel Peter Fairbanks visits the studio set as a consultant for the war film, and with him he has brought his beautiful daughter Antoinett, known as "Tony" (Dorothy Lamour). Don is smitten by Tony, and also realizes that his ticket out of the Army is to marry the colonel's daughter to avoid the draft.
Don manages to insult the colonel gravely when he first mistakes him for an actor and treats him disrespectfully. Even so, Don manages to go on a date with Tony, and even proposes to her, before hearing on the radio that the draft age is only  going up to the age of 31.  As Don is 32 he retracts his proposal, and Tony is disgusted with his intentions and cowardly behavior.

A: Who is mistaken for an actor?

Q: Passage: Texas Rangers Gene Autry and Frog Millhouse are traveling undercover as western troubadours in search of the killer of old, half-blind Frank Martin. Their only clues are a guitar string (the murder weapon) and Martin's horse Swayback that hold the key to finding the dead man's lost goldmine.
Following Frank Martin's funeral, Martin's granddaughter, Joan, meets her uncle, John Martin, and Lon Dillon, who flirts with her. Lawyer Henry Nolan reads Martin's will, revealing that the deceased left John $5,000 and the remainder of the estate to Joan. John tells Joan that he suspects Gene of her grandfather's murder and persuades her to hold a masquerade dance to lure Gene into town.
Meanwhile, Gene learns that Martin was nearly blind and relied on his horse Swayback to guide him. By following Swayback, whom Lon, John, and Henry have all tried to buy, Gene discovers that Martin had indeed located a gold mine. Gene and Frog escape a trap set for them at the dance and save Joan when she is nearly strangled by another guitar string. Then Gene discovers that John's guitar is missing a string.
John and Pablo, who have uncovered Swayback's hiding place, find the mine and are followed by Henry, Lon, and Hank Polk. As they argue among themselves, Gene surprises them and reveals that he is a Texas Ranger assigned to the Martin murder case. By claiming that Frog is a fingerprint expert, Gene tricks Henry into admitting his guilt. Henry is then arrested by the sheriff, who is waiting in the mine according to Gene's instructions. Finally, Joan learns that Gene has recorded the deed to the mine in her name.
