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.

Question: Passage: Nixon in China is an opera in three acts by John Adams, with a libretto by Alice Goodman. Adams' first opera, it was inspired by U.S. President Richard Nixon's 1972 visit to China. The work premiered at the Houston Grand Opera on October 22, 1987, in a production by Peter Sellars with choreography by Mark Morris. When Sellars approached Adams with the idea for the opera in 1983, Adams was initially reluctant, but eventually decided that the work could be a study in how myths come to be, and accepted the project. Goodman's libretto was the result of considerable research into Nixon's visit, though she disregarded most sources published after the 1972 trip.
To create the sounds he sought, Adams augmented the orchestra with a large saxophone section, additional percussion, and electronic synthesizer. Although sometimes described as minimalist, the score displays a variety of musical styles, embracing minimalism after the manner of Philip Glass alongside passages echoing 19th-century composers such as Wagner and Johann Strauss. With these ingredients, Adams mixes Stravinskian 20th-century neoclassicism, jazz references, and big band sounds reminiscent of Nixon's youth in the 1930s. The combination of these elements varies frequently, to reflect changes in the onstage action.
Following the 1987 premiere, the opera received mixed reviews; some critics dismissed the work, predicting it would soon vanish. However, it has been presented on many occasions since, in both Europe and North America, and has been recorded twice. In 2011, the opera received its Metropolitan Opera debut, a production based on the original sets, and in the same year was given an abstract production in Toronto by the Canadian Opera Company. Recent critical opinion has tended to recognize the work as a significant and lasting contribution to American opera.

Answer: What is the first name of the person who was in China in Adam's opera?


Question: Passage: Robert and Mamie Eunson (Cameron Mitchell and Glynis Johns) are Scots who have just landed in America (the year is 1856), having been invited there by Mamie's uncle. They arrive in the tiny logging village of Eureka, only to be informed that the uncle has died when his cabin has been incinerated in a house fire. The Eunsons are assisted by the friendly locals in reconstructing the house and Robert takes to tipping timber.
Mamie is heavily pregnant upon their reaching Eureka; she delivers baby Robbie soon after the cabin is completed. Robert first works for a logging camp as a lumberjack. He eventually wins over Tom Cullen the cruel Irish-American lumber-camp boss. Later Robert starts a successful boat building business and Mamie gives birth to five more children: Jimmy, Kirk, Annabelle, Elizabeth, and Jane. 
The Eunsons are prospering and happy until little Kirk is diagnosed with diphtheria. Mamie and Kirk are quarantined while Robert takes the other children away. The boy recovers, but the goodbye kiss Kirk gave his Dadda before his departure proves fatal, and Robert succumbs. Mamie takes to working as a seamstress and Robbie becomes the man of the house. Things stabilize, but only briefly: tired and work-worn, Mamie contracts typhoid. Knowing she will not survive, she charges Robbie, her eldest, with finding good homes for his siblings, with families that have children, so they will not be lonely.

Answer: What are the first names of the people who arrive in Eureka?


Question: Passage: During a choir practice two days before Christmas, village organist Franz Gruber is worried to hear unusual sounds from the church organ and suspects the bellows. One of Gruber's sons discovers mice in the pipes of the organ and the mice have chewed up parts of the organ. Without the organ the church choir cannot perform the rehearsed Bach piece because the music was written to be performed with an organ.
Accompanied by both his sons, Gruber travels to Salzburg, hoping to buy spare parts and then mend the organ when returning to the village. The party is caught in a snow storm and the spare part is lost on the way home but pastor Joseph Mohr is simply thankful they are unharmed.
Pastor Mohr (with a little help from the bell-ringer Otto) writes the lyrics for a song and the next morning he brings it to Gruber, asking him to compose a melody for the lyrics. With some inspiration from his wife, Gruber sets music to Mohr's words. At church Gruber and Mohr presents "Silent Night" performed a cappella by the choir.

Answer:
Who are the people related to Franz in the party that is caught in a snow storm?
