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: Ravel was not by inclination a teacher, but he gave lessons to a few young musicians he felt could benefit from them. Manuel Rosenthal was one, and records that Ravel was a very demanding teacher when he thought his pupil had talent. Like his own teacher, Faure, he was concerned that his pupils should find their own individual voices and not be excessively influenced by established masters. He warned Rosenthal that it was impossible to learn from studying Debussy's music: "Only Debussy could have written it and made it sound like only Debussy can sound." When George Gershwin asked him for lessons in the 1920s, Ravel, after serious consideration, refused, on the grounds that they "would probably cause him to write bad Ravel and lose his great gift of melody and spontaneity". The best known composer who studied with Ravel was probably Ralph Vaughan Williams, who was his pupil for three months in 190708. Vaughan Williams recalled that Ravel helped him escape from "the heavy contrapuntal Teutonic manner ... Complexe mais pas complique was his motto."Vaughan Williams's recollections throw some light on Ravel's private life, about which the latter's reserved and secretive personality has led to much speculation. Vaughan Williams, Rosenthal and Marguerite Long have all recorded that Ravel frequented brothels. Long attributed this to his self-consciousness about his diminutive stature, and consequent lack of confidence with women. By other accounts, none of them first-hand, Ravel was in love with Misia Edwards, or wanted to marry the violinist Helene Jourdan-Morhange. Rosenthal records and discounts contemporary speculation that Ravel, a lifelong bachelor, may have been homosexual. Such speculation recurred in a 2000 life of Ravel by Benjamin Ivry; subsequent studies have concluded that Ravel's sexuality and personal life remain a mystery.Ravel's first concert outside France was in 1909. As the guest of the Vaughan Williamses, he visited London, where he played for the Societe des Concerts Francais, gaining favourable reviews and enhancing his growing international reputation.
answer:
What was the name of the person that Faure taught?

Passage: "Missing My Baby" is a mid-tempo R&B ballad with influences of urban and soul music. It is in the key of D major, at 144 beats per minute in common time. The recording incorporates melisma, with sung poetry during the downtempo part of the song. The melody is accompanied by backing vocals, and instrumentation is provided by an electric piano, drums, a keyboard, a synthesizer and strings. Contemporary music critics praised Selena's emotive enunciation, which emphasized the song's title and central theme. R&B duo Full Force were the backing vocalists for the original and remix versions of "Missing My Baby".J.R. Reynolds, formerly of Billboard, called "Missing My Baby" a "dreamy ballad" with an "R&B-styled melody under Selena's pop vocals". Ramiro Burr of the Austin American-Statesman described it as a soul ballad. Jerry Johnston of the Deseret News thought that Selena displayed a "Leslie Gore [sic] baby-voice" in "Missing My Baby" and that she "displays a wonderful suppleness in her voice". The Virginian-Pilot said that the song was built on hooks that recall Diana Ross's "Missing You", which is a tribute to Marvin Gaye, and the Beach Boys' "Good to My Baby".The song begins with a drum solo before the other instruments enter to form the musical foundation. Selena sings to her absent lover about how much she misses him, saying that he is "always on [her] mind" and that she feels lonely when he is not with her. Three times she sings, "I often think of the happy times we spent together / And I just can't wait to tell you that I love you". In the chorus, she sings of wanting to hold him tight and feel his heartbeat.
answer:
About whom is Selena singing of wanting to hold him tight and feel his heartbeat?

question:
Passage: Fish found in Shoshone National Forest include at least six species and subspecies of trout including rainbow, brook and brown trout. The Yellowstone cutthroat trout is widespread throughout the Greater Yellowstone Ecosystem, but in the forest is mostly limited to the Shoshone River. The mountain whitefish is also found in the Shoshone River, while the burbot is found in two streams in the southern regions of the forest.There are more than a dozen species of reptiles in the forest including the venomous prairie rattlesnake which can be found at lower elevations. The western painted and the ornate box turtle are turtle species known to exist and about eight species of lizards such as the greater short-horned lizard have been documented. Amphibians such as the Columbia spotted frog and the boreal toad are considered species of concern because of their high susceptibility to disease, habitat loss and human introduced toxins. Boreal toads are found at elevations of between 7,380 and 11,800 ft (2,250 and 3,600 m) and the Columbia spotted frog can live at elevations as high as 9,480 ft (2,890 m) in the Greater Yellowstone Ecosystem.Exotic species of fauna such as the zebra and quagga mussels and the New Zealand mud snail are invasive species that can greatly impact fish species. Though the mussel species are not known to be in Wyoming, several surrounding regions have reported them. The New Zealand mud snail has been found in the Shoshone River east of the forest. Forest managers have established a preventative program to try to keep these species from entering forest waterways.
answer:
What is the name of the invasive species that has been found in the Shoshone river?
