Passage: Nine Inch Nails, an industrial rock band fronted by Trent Reznor, has toured all over the world since its creation in 1988. While Reznor—the only official member until adding Atticus Ross in 2016—controls its creative and musical direction in the studio, the touring band performs different arrangements of the songs. In addition to regular concerts, the band has performed in both supporting and headlining roles at festivals such as Woodstock '94, Lollapalooza 1991 and 2008, and many other one-off performances including the MTV Video Music Awards. Prior to their 2013 tour, the band had played 938 gigs.Nine Inch Nails' live performances contrast with its in-studio counterpart.
Reznor writes and performs nearly all Nine Inch Nails studio material, with occasional instrumental and vocal contributions from others artists. However, Reznor has typically assembled groups of backing musicians to interpret songs for tours and other live performances. Keyboardist Alessandro Cortini said that "if you see the show and you're used to the CDs it's pretty clear that the studio entity is different from the live entity".The only constant member of the live band is Reznor.  Live Nine Inch Nails performances are typically accompanied by lighting, stage, and video projection effects. Since 1999, the visual design components of live shows have been curated by Reznor with Rob Sheridan. Three tours have been chronicled on live albums and tour documentaries.
Critical and commercial response to Nine Inch Nails live performances has generally been positive. Critics have pointed to the concerts' aggressive on-stage dynamic and visual designs as high points. Reznor decided in 2008 to cease touring with the band after a 2009 farewell tour. The band resumed touring in 2013, with the group planning a set of concerts in the U.S. beginning September 28. 
Question: What's the full name of the man who was the only official member of Nine Inch Nails until 2016?
Trent Reznor.

Passage: Josh and Dinah Barkley (Fred Astaire and Ginger Rogers) are a husband-and-wife musical comedy team at the peak of their careers. After finishing a new show, Dinah meets serious French playwright Jacques Pierre Barredout, who suggests that Dinah should take up dramatic acting. Dinah tries to keep the suggestion a secret from Josh, but when he finally discovers Dinah hiding a script for Jacques' new show from him, the couple splits up.  
Their good friend, acerbic composer Ezra Miller tries to trick them back together again, but fails.  When Josh secretly watches Dinah's rehearsals for Barredout's new play and sees how she is struggling, he calls her up and pretends to be the Frenchman, giving her notes that help her to understand her part, the young Sarah Bernhardt. As the result, Dinah gives a brilliant performance. After the show, she accidentally learns that her late-night mentor was Josh and not Barredout, so she rushes to Josh's apartment and the two reconcile. 
Question: What is the last name of the late-night mentor?
Barkley.

Passage: As an artist, Francis Bacon was a late starter. He painted sporadically and without commitment during the late 1920s and early 1930s, when he worked as an interior decorator and designer of furniture and rugs. He later admitted that his career was delayed because he had spent so long looking for a subject that would sustain his interest. He began to paint images based on the Crucifixion in 1933, when his then-patron Eric Hall commissioned a series of three paintings based on the subject. These abstract figurations contain formal elements typical of their time, including diaphanous forms, flat backgrounds, and surrealist props such as flowers and umbrellas. The art critic Wieland Schmied noted that while the early works are "aesthetically pleasing", they lack "a sense of urgency or inner necessity; they are beautiful, but lifeless". The sentiment is echoed by Hugh Davies, who wrote that Bacon's 1933 paintings "suggest an artist concentrating more on formal than on expressive concerns". Bacon admitted that his early works were not successful; they were merely decorative and lacking in substance. He was often harshly self-critical during this period, and would abandon or destroy canvasses before they were completed. He abandoned the Crucifixion theme, then largely withdrew from painting in frustration, instead immersing himself in love affairs, drinking and gambling.When he returned to the topic of the Crucifixion eleven years later, he retained some of the stylistic elements he had developed earlier, such as the elongated and dislocated organic forms that he now based on Oresteia. He continued to incorporate the spatial device he was to use many times throughout his career—three lines radiating from this central figure, which was first seen in Crucifixion, 1933. Three Studies was painted over the course of two weeks in 1944, when, Bacon recalled, "I was in a bad mood of drinking, and I did it under tremendous hangovers and drink; I sometimes hardly knew what I was doing. I think perhaps the drink helped me to be a bit freer." The painting was executed in a ground-floor flat at 7 Cromwell Place, South Kensington in London. A large back room in the building had been converted into a billiard room by its previous occupant, artist John Everett Millais. It was Bacon's studio by day; at night, abetted by Eric Hall and Bacon's childhood nanny Jessie Lightfoot, it functioned as an illicit casino.Although he had been painting for almost twenty years, Bacon steadfastly insisted that Three Studies was the fons et origo of his career. He destroyed many of his earlier canvasses, and tried to suppress those that had left his studio. Bacon was emphatic that no pre-1944 images be admitted into his canon, and most of the early art critics agreed with this position. The early publications of John Russell and David Sylvester open with the 1944 triptych, and Bacon insisted to his death that no retrospective should feature paintings pre-dating 1944. 
Question: What is last name of the person who returned to the topic of the Crucifixion eleven years after abandoning it?

Bacon.
