[Q]: Question: "Rather than agreeing on their respective practices, Buddhist schools do 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." Answer:

[Q]: Question: "What genre did Chopin create?" Context: "Chopin took the new salon genre of the nocturne, invented by the Irish composer John Field, to a deeper level of sophistication.

He exploited the poetic potential of the concept of the concert etude, already being developed in the 1820s and 1830s by Liszt, Clementi and Moscheles, in his two sets of studies (Op. 10 published in 1833, Op. 25 in 1837)."
