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.

Input: Consider Input: Passage: A man unveils a valuable painting he picked up for $50,000 and is killed. A card with a large black ace (of spades) is put on his chest. Another "Black Ace" victim. The killer sends his victims a Black Ace card, warning them they are to die and then kills them, his way of taunting the police. Neil Broderick, an author, intends writing a book about him and is on his way to see Thornton Drake to get more information about him. Austin Winters is his secretary and Neil met his daughter Martha on the train, on the way to Chicago.
Drake has just received a Black Ace, with the words: "At seven tomorrow night", the time he is to be killed. Two plainclothes cops arrive from police headquarters, having had a call, Clancy and Dugan (both incompetents). Martha suggests that they leave for Drake's Louisiana plantation tomorrow morning and be far away from there at seven tomorrow night. Drake agrees and suggests they all go. On the flight, the lights go off for some seconds and when they come on again, Austin Winters is dead without a mark on him.
At the plantation, Clancy ineptly questions the suspects till Neil points out that they are now in another state, so out of their jurisdiction. Neil goes to another room and makes a phone call, then signals to someone outside. After he finishes his call, the line is cut. Meanwhile one of the pilots has taken off in the plane, leaving the other pilot, Henderson, behind who claims he does not know anything though he was out of the cockpit when Winters was killed.
The coroner finds a letter on the dead man which is to be read if Winters dies. It will reveal the identity of the Black Ace. Clancy starts reading it aloud and unsurprisingly the lights go off and the letter has vanished when the lights are turned on again. People locked in their rooms that night and Neil has a hidden car outside signal to him.

Output: Who is Neil Broderick writing a book about?

Input: Consider Input: Passage: In turn-of-the-century Oakland, California, the teenaged Myrtle McKinley is expected to follow high school by attending a San Francisco business college. Instead, she takes a job performing with a traveling vaudeville troupe, where she meets and falls in love with singer-dancer Frank Burt.
Frank proposes they marry and also entertain on stage together as an act, which proves very popular. Myrtle retires from show business after giving birth to daughters Iris and Mikie, while her husband goes on tour with another partner.
A few years later, less successful now, Frank persuades his wife to return to the stage. The girls are cared for by their grandmother as their parents leave town for months at a time.
Iris and Mikie are school girls when they are given a trip to Boston to see their parents. Iris meets a well-to-do young man, Bob Clarkman, and is permitted to attend an exclusive boarding school there. She is embarrassed by her parents' profession, however, and mortified at what the reaction will be from Bob and all of her new school friends when they learn that her parents are performing nearby.
Myrtle and Frank take matters into their own hands, arranging with the school to have all of the students attend a show. To her great relief, Iris is delighted when her classmates adore her parents' sophisticated act. By the time she's out of school and ready to marry, Iris wants to go into show business herself.

Output: What is the last name of the person who falls in love with Frank?

Input: Consider Input: Passage: The Iroquoian-speaking Susquehannocks were the earliest recorded inhabitants of the West Branch Susquehanna River basin, which includes Quehanna Wild Area. They were a matriarchal society that lived in stockaded villages of large long houses. The Susquehannocks' numbers were greatly reduced by disease and warfare with the Five Nations of the Iroquois, and by 1675 they had died out, moved away, or been assimilated into other tribes. After this, the Iroquois exercised nominal control of the lands of the West Branch Susquehanna River valley. They also lived in long houses, primarily in what is now New York, and had a strong confederacy which gave them power beyond their numbers. To fill the void left by the demise of the Susquehannocks, the Iroquois encouraged such displaced eastern tribes as the Shawnee and Lenape (or Delaware) to settle in the West Branch watershed.The Seneca tribe of the Iroquois hunted in much of Pennsylvania and the Quehanna area. The Iroquois and other tribes used the Great Shamokin Path, the major native eastwest path connecting the Susquehanna and Allegheny River basins, which passed south of what is now the wild area. The native village of Chinklacamoose (or Chingleclamouche) was on this path at the West Branch Susquehanna River, at what is now Clearfield to the southwest of Quehanna. The Sinnemahoning Path along Sinnemahoning Creek ran north of Quehanna; as the path with the gentlest grade, it may have been the route the first Paleo-Indians took entering this part of Pennsylvania from the west.The French and Indian War (17541763) and the subsequent colonial expansion encouraged the migration of many Native Americans westward to the Ohio River basin. In October 1784, the United States acquired a large tract of land, including what is now Quehanna Wild Area, from the Iroquois in the Second Treaty of Fort Stanwix; this acquisition is known as the Last Purchase, as it completed the series of purchases from the resident Native American tribes of lands within the boundaries of Pennsylvania, initiated by William Penn and continued by his heirs.Although most of the Native Americans left this area of Pennsylvania, the state's Native American heritage can be found in many of its place names. The Susquehannocks were also known as the Susquehanna, from which the Susquehanna River and its West Branch obtained their names. In the 1950s the Curtiss-Wright Corporation coined the name "Quehanna" for its nuclear reservation, which it derived from the last three syllables of "Susquehanna", "in honor of the river that drained the entire region". Part of Quehanna Wild Area lies in the Moshannon State Forest, named for Moshannon Creek, which means "moose stream" or "elk stream" in the Lenape language. Sinnemahoning Creek's name means "stony salt lick" in Lenape.
Output: What path had the gentlest grade and might have been the route the first Paleo-Indians took entering Pennsylvania from the west?
