Given the task definition, example input & output, solve the new input case.
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.
Example: Passage: Nearing London, Oliver encounters Jack Dawkins, a pickpocket more commonly known by the nickname the "Artful Dodger", and his sidekick, a boy of a humorous nature named Charley Bates, but Oliver's innocent and trusting nature fails to see any dishonesty in their actions. The Dodger provides Oliver with a free meal and tells him of a gentleman in London who will "give him lodgings for nothing, and never ask for change". Grateful for the unexpected assistance, Oliver follows the Dodger to the "old gentleman's" residence. In this way Oliver unwittingly falls in with an infamous Jewish criminal known as Fagin, the gentleman of whom the Artful Dodger spoke. Ensnared, Oliver lives with Fagin and his gang of juvenile pickpockets in their lair at Saffron Hill for some time, unaware of their criminal occupations. He believes they make wallets and handkerchiefs.
Output: Who believes Fagin's gang make wallets and handkerchiefs?.
This question is based on the following sentence in the passage "He believes they make wallets and handkerchiefs". It evaluates the understanding that the pronoun "he" refers to name "Oliver". You can ask questions like this one about most pronouns in a paragraph.

New input case for you: Passage: Sons of Soul bridged the gap between commercial and critical success for Tony! Toni! Toné!, helping them become one of the most popular acts in R&B at the time. Its success exemplified the genre's commercial resurgence during the early 1990s, when hip hop became the predominant African-American music genre in the mainstream. In 1994, Greg Kot of the Chicago Tribune attributed its resurgence to younger artists' blend of live instrumentation and hip hop production values, and cited Sons of Soul as "the most accomplished merger of hip-hop attitude with a '70s R&B aesthetic." The Atlanta Journal-Constitution hailed it as "a gentle reminder of those glory days" and felt that the group having both vocal and musical talents is most indicative of a return to early R&B's aesthetics. Furthermore, they garnered mainstream attention in a year of several high-profile controversies with R&B and hip hop artists such as Michael Jackson and Snoop Dogg. David W. Brown of The Harvard Crimson wrote that Tony! Toni! Toné! is "known primarily for the quality of its music, not its extracurricular reputation, unlike other groups such as Jodeci who rely on a playa-gangsta-mack image to sell-records."Along with acts such as Mint Condition and R. Kelly, Tony! Toni! Toné! played live instruments that complemented their hip hop sensibilities. Their concerts featured visual elements such as incense smoke and kaleidoscopic stage lighting, the group's eccentric wardrobe, and additional instrumentalists, including another guitarist, two drummers, two keyboardists, a violinist, a trumpeter, and a saxophonist. The Charlotte Observer remarked on the group in 1994: "[T]heir use of live instruments on record and onstage makes them an anomaly in the synthesized and sampled world of modern R&B." With the group's reliance on traditional soul and R&B values of songwriting and instrumentation, Sons of Soul was a precursor to the neo soul movement of the 1990s. Matt Weitz of The Dallas Morning News wrote in 1993 that the group had distinguished themselves from their New jack swing contemporaries with Sons of Soul and found them aesthetically akin to acts such as Prince and P.M. Dawn. Raphael Wiggins said of their success with the album:
"We've been very blessed to be able to be a group that writes our own songs and people have accepted us from both sides, hip hop and the R&B crowd or whatever you might want to say. I feel very fortunate to be able to do that here in 1993–94, because like you know, it was starting to be a dying thing that was happening. But I guess we were like the bridge between hip hop and soul and R&B, and being a little bit commercial also helped us. A lot of humor, a lot of nice slow songs and being able to play kind of brought us a foundation.".
Output:
Who garnered mainstream attention in a year of several high-profile controversies with R&B and hip hop artists?
