instruction:
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.

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?

Passage: Scene: A Ruined Temple on the Summit of Mount Olympus
On Mount Olympus, the elderly deities complain of feeling old and lament their waning influence on Earth. Mercury complains that the older gods are lazy and leave all their duties to him, while he gets no credit for all his drudgery. Jupiter says that matters have reached a crisis, but he is unsure what can be done about it. Just then, the gods see a swarm of mortals ascending the mountain and withdraw to observe them from a distance.
Thespis's acting company enters for a picnic celebrating the marriage of two of its members, Sparkeion and Nicemis. The actors, being cheap, have failed to contribute substantial food items to the picnic. Sparkeion flirts with his former fiancee, Daphne, which annoys Nicemis. In retaliation, Nicemis flirts with her old suitor, Thespis, but he declines to flirt back. Thespis explains to his troupe that a successful manager must be aloof from those he manages, or he will lose his authority.
Jupiter, Mars and Apollo enter. All of the actors flee in terror, except for Thespis. Jupiter asks Thespis whether he is impressed with the father of the gods. Thespis replies that the gods are unimpressive and suggests that they go down to earth in disguise to "mingle" and judge for themselves what people think of them. They agree to invest the actors with their powers, as they take a merry holiday below on Earth. Thespis agrees that he and his company will keep things running on Mount Olympus during the gods' absence. Each actor takes the place of one of the gods, with Thespis himself replacing Jupiter. Mercury stays behind to offer any advice the actors may need.
answer:
What are the names of the gods that see a swarm of mortals ascending the mountain?

Passage: Failing to sell at the Summer Exhibition, The Combat was bought from Etty by fellow artist John Martin for 300 guineas (about 24,000 in 2019 terms), following a promise Martin had made to Etty before the painting was complete. The painting was too large for Martin's house, and in 1831 he sold it on to the Royal Scottish Academy. It was transferred in 1910 to the nearby National Gallery of Scotland where it remains. One of Etty's major works, it was exhibited at numerous major exhibitions including the seminal Art Treasures Exhibition of 1857, before Etty fell out of fashion in the second half of the 19th century.
Throughout his life, The Combat continued to be considered one of Etty's most powerful paintings. In 1845, Etty took a smaller 89 by 118 cm (35 by 46 in) copy of The Combat, which had been painted by an unknown Edinburgh artist, and completely reworked it to serve as the basis for an engraving by George Thomas Doo. The engraving was published three years later, and the painting used as its model passed through the hands of several collectors in subsequent years, before entering the collection of the Ringling Museum in 1934. A number of sketches attributed to Etty, under the name of A Study for Mercy Interceding for the Vanquished, are also in circulation.After the success of The Combat, Etty continued with his preferred theme of history paintings containing nudity; of the 15 pictures he exhibited at the Royal Academy during the 1820s (including Cleopatra, Pandora and The Combat) all but one contained a nude figure. He was elected a full Royal Academician in 1828, at that time the most prestigious honour available to an artist. The Combat was the first very large work attempted by Etty, and its success prompted him to produce further works on a similar scale over the rest of his career; he produced nine very large paintings illustrating moral themes throughout his career. As time went by his canvases came to be increasingly dominated by nude women.The 1832 exhibition of Youth on the Prow, and Pleasure at the Helm, a painting containing apparently gratuitous nude figures, met a hostile reception from critics. From then on, while Etty continued to paint nude figures for the rest of his career, he made a conscious effort to try to illustrate moral lessons with his work. This effort was not wholly successful, and he continued to be regarded as a pornographer by some throughout his career. He died in late 1849, and following his death nude paintings went rapidly out of fashion in Britain.
answer:
What was the name of the person that painted the painting that the Royal Scottish Academy purchased?
