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 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.
[A]: Who is Neil Broderick writing a book about?


[Q]: Passage: Washington, D.C. is located in the mid-Atlantic region of the U.S. East Coast. Due to the District of Columbia retrocession, the city has a total area of 68.34 square miles (177.0 km2), of which 61.05 square miles (158.1 km2) is land and 7.29 square miles (18.9 km2) (10.67%) is water. The District is bordered by Montgomery County, Maryland to the northwest; Prince George's County, Maryland to the east; Arlington County, Virginia to the south; and Alexandria, Virginia to the west.
The south bank of the Potomac River forms the District's border with Virginia and has two major tributaries: the Anacostia River and Rock Creek. Tiber Creek, a natural watercourse that once passed through the National Mall, was fully enclosed underground during the 1870s. The creek also formed a portion of the now-filled Washington City Canal, which allowed passage through the city to the Anacostia River from 1815 until the 1850s. The Chesapeake and Ohio Canal starts in Georgetown and was used during the 19th century to bypass the Little Falls of the Potomac River, located at the northwest edge of Washington at the Atlantic Seaboard fall line.The highest natural elevation in the District is 409 feet (125 m) above sea level at Fort Reno Park in upper northwest Washington. The lowest point is sea level at the Potomac River. The geographic center of Washington is near the intersection of 4th and L Streets NW.The District has 7,464 acres (30.21 km2) of parkland, about 19% of the city's total area and the second-highest percentage among high-density U.S. cities. This factor contributed to Washington, D.C., being ranked as third in the nation for park access and quality in the 2018 ParkScore ranking of the park systems of the 100 most populous cities in the United States, according to the nonprofit Trust for Public Land.The National Park Service manages most of the 9,122 acres (36.92 km2) of city land owned by the U.S. government. Rock Creek Park is a 1,754-acre (7.10 km2) urban forest in Northwest Washington, which extends 9.3 miles (15.0 km) through a stream valley that bisects the city. Established in 1890, it is the country's fourth-oldest national park and is home to a variety of plant and animal species, including raccoon, deer, owls, and coyotes. Other National Park Service properties include the C&O Canal National Historical Park, the National Mall and Memorial Parks, Theodore Roosevelt Island, Columbia Island, Fort Dupont Park, Meridian Hill Park, Kenilworth Park and Aquatic Gardens, and Anacostia Park. The D.C. Department of Parks and Recreation maintains the city's 900 acres (3.6 km2) of athletic fields and playgrounds, 40 swimming pools, and 68 recreation centers. The U.S. Department of Agriculture operates the 446-acre (1.80 km2) U.S. National Arboretum in Northeast Washington.
[A]: What is the country's fourth-oldest national park?


[Q]: Passage: 2017 marks the 50th anniversary of Jayne Mansfield's fatal and legendary car crash, yet we still are left to wonder: was her life spinning out of control in the last two years of her life, or...did the devil make her do it?
Even knowing how the story ends, who could resist cheering for Jayne Mansfield (the king-sized over-the-top punked-out Marilyn Monroe who became the ultimate atomic-era sex-kitten-gone-berserk) as she navigates the cultural and spiritual landscape of a quickly changing world in the mid-1960s?
Defined by her hunger for publicity, on the one hand Jayne was Hollywood Babylon made flesh, with five kids, three messy divorces, and a lurid death that may or may not have been caused by a Satanic curse. On the other hand, she had perfect comic timing, 163 IQ, spoke five languages and was outspokenly anti-war, making her impossible to categorize, though the headlines that her wild life inspired certainly tried: Can A Sex Siren Be A Good Mother, Love Goddess With A Jinx, the Smartest Dumb Blonde...
And then there was her reported affair with Anton LaVey, head of the Church of Satan. The handsomely devilish Anton started his "church" with a publicist and preached a live and let live lifestyle. "If you're going to be a sinner, be the best sinner on the block," said Anton and that was music to sex-positive Jayne Mansfield's ears. Unfortunately, her then-boyfriend lawyer Sam Brody was sent into a jealous rage and desecrated sacred Satanic talismans in Anton's lair, prompting a curse to be put on his head that he would die in a car accident within a year. In 1966 and 1967, Jayne and Sam proceeded to have seven fender benders and near-fatal smash-ups until the one that tragically took both of their lives in a bizarre crash where reporters said alternately Jayne was either beheaded on impact or wig-scalped.
[A]:
Who was said to cause the curse on Anton?
