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:
Passage: Stefen "Stef" Djordjevic is a Serbian American high school defensive back who is gifted in both sports and academics. He is seeking a college football scholarship to escape the economically depressed small western Pennsylvania town of Ampipe and a dead-end job and life working at the mill like his father and brother Greg. He dreams of becoming an engineer right after he graduates from college. Ampipe is a company town whose economy is dominated by the town's main employer, American Pipe & Steel, a steel mill struggling through the downturn of the early 1980s recession. Stef gets through his days with the love of his girlfriend, Lisa Lietzke, and his strong bond with his teammates.
Most of the film takes place after the big football game against undefeated Walnut Heights High School. Ampipe appears headed to win the game, when a fumbled handoff in the closing seconds—as well as Stefen's pass interference penalty earlier in the game—leads to a Walnut Heights victory. Following the game, Coach Burt Nickerson lambastes the fumbler in the locker room, telling him he "quit" the game. When Stefen retorts that the coach himself quit, the coach kicks him off the team.
In the aftermath, disgruntled Ampipe fans vandalize Coach Nickerson's house and yard. Stefen is present and is a reluctant participant, but is nonetheless seen by Nickerson as the vandals flee. From there, Stefen deals with personal battles, including dealing with the coach blackballing him among colleges because of his attitude and participation in the desecration of Nickerson's yard and house. Stefen gets in an argument with Lisa, and his best friend Brian declines a scholarship offer to USC and plans to marry his pregnant girlfriend. 
Question: What's the nickname of the person who gets removed from the team after standing up to the coach?
answer:
Stef.

Passage: Every year, 12-year old Samuel, 10-year old Jeffrey and 8-year old Michael Douglas visit their grandfather, Mori Tanaka at his cabin. Mori trains his grandchildren in the art of Ninjutsu. As the summer comes to an end, Mori gives each of them a new "ninja" name based on their personalities: 'Rocky', 'Colt', and 'Tum-Tum'. 
Meanwhile, the boys' father, Sam Douglas, is an FBI agent who stages a sting operation to entrap Hugo Snyder in the sale of warheads. Snyder escapes the trap with the use of his own ninja henchmen. Snyder decides to test Mori's fighting skill. The boys ignore Mori's orders to stay in the house and aid by defeating two ninjas on their own. Snyder threatens Mori's family if he doesn't get Douglas off his back, and Mori chides the boys briefly for interfering in his personal affairs. When they return home, they find their father unenthusiastic to see what they had learned during their visit and more annoyed at their new names. Emily, a friend of Rocky's, compliments his new name and agrees to ride with them to school the next day. Snyder develops a plan to kidnap the boys to use them as leverage to get Douglas to back off.

Due to Douglas and his FBI crew's presence, they are unable to capture the boys.
