Q: Extract the answer to the question from the following context. Question: What does the C in "DCT" stand for? Context: Today, nearly all commonly used video compression methods (e.g., those in standards approved by the ITU-T or ISO) apply a discrete cosine transform (DCT) for spatial redundancy reduction. The DCT that is widely used in this regard was introduced by N. Ahmed, T. Natarajan and K. R. Rao in 1974. Other methods, such as fractal compression, matching pursuit and the use of a discrete wavelet transform (DWT) have been the subject of some research, but are typically not used in practical products (except for the use of wavelet coding as still-image coders without motion compensation). Interest in fractal compression seems to be waning, due to recent theoretical analysis showing a comparative lack of effectiveness of such methods.
A: cosine

Q: Extract the answer to the question from the following context. Question: How do Catholic traditionally explain Jesus' brothers? Context: The Perpetual Virginity of Mary asserts Mary's real and perpetual virginity even in the act of giving birth to the Son of God made Man. The term Ever-Virgin (Greek ) is applied in this case, stating that Mary remained a virgin for the remainder of her life, making Jesus her biological and only son, whose conception and birth are held to be miraculous. While the Orthodox Churches hold the position articulated in the Protoevangelium of James that Jesus' brothers and sisters are older children of Joseph the Betrothed, step-siblings from an earlier marriage that left him widowed, Roman Catholic teaching follows the Latin father Jerome in considering them Jesus' cousins.
A: considering them Jesus' cousins

Q: Extract the answer to the question from the following context. Question: Who did Kanye think deserved best female video Context: On September 13, 2009, during the 2009 MTV Video Music Awards while Taylor Swift was accepting her award for Best Female Video for "You Belong with Me", West went on stage and grabbed the microphone to proclaim that Beyonce's video for "Single Ladies (Put a Ring on It)", nominated for the same award, was "one of the best videos of all time". He was subsequently removed from the remainder of the show for his actions. When Beyonce later won the award for Best Video of the Year for "Single Ladies (Put a Ring on It)", she called Swift up on stage so that she could finish her acceptance speech. West was criticized by various celebrities for the outburst, and by President Barack Obama, who called West a "jackass". In addition, West's VMA disruption sparked a large influx of Internet photo memes with blogs, forums and "tweets" with the "Let you finish" photo-jokes. He posted a Tweet soon after the event where he stated, "Everybody wanna booooo me but I'm a fan of real pop culture... I'm not crazy y'all, I'm just real." He then posted two apologies for the outburst on his personal blog; one on the night of the incident, and the other the following day, when he also apologized during an appearance on The Jay Leno Show. After Swift appeared on The View two days after the outburst, partly to discuss the matter, West called her to apologize personally. Swift said she accepted his apology.
A: Beyonce

Q: Extract the answer to the question from the following context. Question: The triple gem is also called what? Context: Buddhist schools vary on the exact nature of the path to liberation, the importance and canonicity of various teachings and scriptures, and especially their respective practices. Buddhism denies a creator deity and posits that mundane deities such as Mahabrahma are misperceived to be a creator. The foundations of Buddhist tradition and practice are the Three Jewels: the Buddha, the Dharma (the teachings), and the Sangha (the community). Taking "refuge in the triple gem" has traditionally been a declaration and commitment to being on the Buddhist path, and in general distinguishes a Buddhist from a non-Buddhist. Other practices are Ten Meritorious Deeds including, giving charity to reduce the greediness; following ethical precepts; renouncing conventional living and becoming a monastic; the development of mindfulness and practice of meditation; cultivation of higher wisdom and discernment; study of scriptures; devotional practices; ceremonies; and in the Mahayana tradition, invocation of buddhas and bodhisattvas.
A:
the Three Jewels
