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: One of the most persistent and popular stories regarding the Mormon pioneers was about three of the rescuers who helped the pioneers cross Sweetwater River. The most popular telling, by Solomon Kimball, states:
Three eighteen-year-old boys belonging to the relief party came to the rescue; and to the astonishment of all who saw, carried nearly every member of that ill-fated handcart company across the snow-bound stream. The strain was so terrible, and the exposure so great, that in later years all the boys died from the effects of it. When President Brigham Young heard of this heroic act, he wept like a child, and later declared publicly, "That act alone will ensure C. Allen Huntington, George W. Grant, and David P. Kimball an everlasting salvation in the Celestial Kingdom of God, worlds without end.
This version was quoted by Gordon B. Hinckley, James E. Faust and was previously taught in Sunday School in the LDS Church for both adults and children.Chad Orton notes it would be physically impossible for three boys to carry five hundred people across the river in two hours. In actuality, the rescue party had several rescuers instead of three, eighteen of which have been positively identified as being at the Sweetwater crossing. The rescuers brought ten rescue wagons in addition to the wagons the Martin Company had with them. Many survivors wrote about riding the wagons across. However, because of time constraints, not everyone could ride the wagons. Some were carried, but other survivors wrote that they crossed the river themselves or with the help of people other than the three boys. The boys mentioned in the story did help some people across, but not "nearly every member" as reported in the mythologized version of the story. While the three boys were among those that helped several across, the ages were wrong. C. Allen Huntington was 24, David P. Kimball was 17, and George W. Grant was 16. There is no medical evidence that they died from effects of the crossing, and most lived active and relatively long lives. Outside of Kimball's account, there is no other account of Brigham Young promising everlasting salvation to the rescuers based on a single act. Orton notes that such a promise is inconsistent with church doctrine. John Thomas notes that Solomon Kimball did not witness the crossing, but relied heavily on other sources, particularly Orson F. Whitney's 1888 account, who also claimed that all of the boys died from the event, even though Huntington was still alive in 1888.

Output: What are the names of the three eighteen-year-olds who helped the pioneers cross Sweetwater River?

Input: Consider Input: Passage: In 1990, Zappa was diagnosed with terminal prostate cancer. The disease had been developing unnoticed for ten years and was considered inoperable. After the diagnosis, Zappa devoted most of his energy to modern orchestral and Synclavier works. Shortly before his death in 1993 he completed Civilization Phaze III, a major Synclavier work which he had begun in the 1980s.In 1991, Zappa was chosen to be one of four featured composers at the Frankfurt Festival in 1992 (the others were John Cage, Karlheinz Stockhausen, and Alexander Knaifel). Zappa was approached by the German chamber ensemble Ensemble Modern which was interested in playing his music for the event. Although ill, he invited them to Los Angeles for rehearsals of new compositions and new arrangements of older material. Zappa also got along with the musicians, and the concerts in Germany and Austria were set up for later in the year. Zappa also performed in 1991 in Prague, claiming that "was the first time that he had a reason to play his guitar in 3 years", and that that moment was just "the beginning of a new country", and asked the public to "try to keep your country unique, do not change it into something else".In September 1992, the concerts went ahead as scheduled but Zappa could only appear at two in Frankfurt due to illness. At the first concert, he conducted the opening "Overture", and the final "G-Spot Tornado" as well as the theatrical "Food Gathering in Post-Industrial America, 1992" and "Welcome to the United States" (the remainder of the program was conducted by the ensemble's regular conductor Peter Rundel). Zappa received a 20-minute ovation. G-Spot Tornado was performed with Canadian dancer Louise Lecavalier. It was his last professional public appearance as the cancer was spreading to such an extent that he was in too much pain to enjoy an event that he otherwise found "exhilarating". Recordings from the concerts appeared on The Yellow Shark (1993), Zappa's last release during his lifetime, and some material from studio rehearsals appeared on the posthumous Everything Is Healing Nicely (1999).

Output: In what city was Zappa's last professional public appearance?

Input: Consider Input: Passage: A happy vacation along California's rocky coast for a pregnant Mandy Anthony, her husband Dick (Arthur Franz) and her sister Kate Hazelton is ruined when Mandy has a seizure, loses consciousness and miscarries. Worse, when she awakens, she says that she is "Felicia" and calls Dick "Dickens." A stunned Dick tells an uncomprehending Kate that Felicia was his first wife and Dickens was her pet name for him - and that he's never told Mandy of his first marriage, Dickens or Felicia's death six years earlier!
Felicia demands to visit the Bradleys, an elderly couple whom Dick says that Mandy doesn't know. They're Felicia's parents. She convinces them that she is indeed Felicia, back from the dead. Mrs. Bradley is delighted; Mr. Bradley is horrified. Dick, upset by the reunion, tells Kate that Mrs. Bradley "was a strange, evil woman - Felicia, too" and that he was a fool to not face the truth. Meanwhile, Mr. Bradley says to Mrs. Bradley, "God will punish you for this." Mrs. Bradley contemptuously replies, "You believe in your god. I'll believe in mine."
Dick invites his friends John Mitchell and Molly Prentiss to the vacation house for cocktails. Afterwards, Felicia tries to gas Kate in her bedroom - Kate survives when Mandy's voice awakens her - then goes outside and kills their dog, Copper, who loved Mandy but hates Felicia.
The next day, Kate is at John's house when neighbor Nancy Cordell drops by. She casually tells Kate that she and the Bradleys are members of Maitre Renault's (Otto Reichow) devil cult, as was Felicia. Kate expresses an interest and Nancy arranges for Kate to meet Renault.
Output: What are the first names of the three people who are vacationing along California's rocky coast?
