[EX Q]: Passage: By the mid-1960s Harrison had become an admirer of Indian culture and mysticism, introducing it to the other Beatles. During the filming of Help! in the Bahamas, they met the founder of Sivananda Yoga, Swami Vishnu-devananda, who gave each of them a signed copy of his book, The Complete Illustrated Book of Yoga. Between the end of the last Beatles tour in 1966 and the beginning of the Sgt Pepper recording sessions, he made a pilgrimage to India with his wife Pattie; there, he studied sitar with Ravi Shankar, met several gurus, and visited various holy places. In 1968 he travelled to Rishikesh in northern India with the other Beatles to study meditation with Maharishi Mahesh Yogi. Harrison's use of psychedelic drugs encouraged his path to meditation and Hinduism. He commented: "For me, it was like a flash. The first time I had acid, it just opened up something in my head that was inside of me, and I realized a lot of things. I didn't learn them because I already knew them, but that happened to be the key that opened the door to reveal them. From the moment I had that, I wanted to have it all the time – these thoughts about the yogis and the Himalayas, and Ravi's music."In line with the Hindu yoga tradition, Harrison became a vegetarian in the late 1960s. After being given various religious texts by Shankar in 1966, he remained a lifelong advocate of the teachings of Swami Vivekananda and Paramahansa Yogananda – yogis and authors, respectively, of Raja Yoga and Autobiography of a Yogi. In mid-1969, he produced the single "Hare Krishna Mantra", performed by members of the London Radha Krishna Temple. Having also helped the Temple devotees become established in Britain, Harrison then met their leader, A.C. Bhaktivedanta Swami Prabhupada, whom he described as "my friend ... my master" and "a perfect example of everything he preached". Harrison embraced the Hare Krishna tradition, particularly japa-yoga chanting with beads, and became a lifelong devotee.Regarding other faiths he once remarked: "All religions are branches of one big tree. It doesn't matter what you call Him just as long as you call." He commented on his beliefs:. 
Question: Who met the founder of Sivananda Yoga?
[EX A]: Beatles.

[EX Q]: 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?
[EX A]: Trent Reznor.

[EX Q]: Passage: Charles Spotswoode's son Jimmy became involved with "the Canary", a conniving showgirl. The Canary, determined to force Jimmy to marry her so she can join the social elite, threatens to reveal that Jimmy was embezzling from his father. She turns down the elder Spotswoode's bribe to leave Jimmy alone. She telephones two men she has been blackmailing, Cleaver and Mannix, and demands one final generous gift from each of them by the next day. She makes the same request of "creepy" admirer Dr. Lindquist. Her ex-husband Tony Sheel eavesdrops and wants half, but she refuses to give him anything, even after he hits her. Cleaver, Mannix and Lindquist are all shown lurking about her apartment building late that night.
Spotswoode visits her at her apartment around midnight, but cannot get her to change her mind. After he reaches the lobby of her building, he and another person hear screams from her place. They knock on the door, but she assures them that she is fine.
The Canary is found strangled the next day. The coroner places the time of death around midnight. District Attorney Markham investigates, aided by Philo Vance (a close friend of Charles Spotswoode) and Police Sergeant Heath. After all the suspects are brought in for questioning, Vance asks Markham to keep them waiting for a few hours. Markham agrees. Vance subtly maneuvers Cleaver, Mannix, Lindquist and the two Spotswoodes into playing poker to pass the time so he can observe their personality traits. Only one shows the daring, imagination and discipline required for the crime; that man bluffs Vance, betting everything with just a pair of deuces. The suspects are then released.
Sheel, who witnessed the murder while hiding in the closet, sends the killer several blackmail letters. He too is strangled. A pen found at the scene has Jimmy's name on it, so Heath arrests him for the murder. Jimmy then confesses to both murders, but Vance knows better. 
Question: What is the nickname of the person who has been blackmailing someone?
[EX A]:
The Canary.
