Question: iPod batteries are not designed to be removed or replaced by the user, although some users have been able to open the case themselves, usually following instructions from third-party vendors of iPod replacement batteries. Compounding the problem, Apple initially would not replace worn-out batteries. The official policy was that the customer should buy a refurbished replacement iPod, at a cost almost equivalent to a brand new one. All lithium-ion batteries lose capacity during their lifetime even when not in use (guidelines are available for prolonging life-span) and this situation led to a market for third-party battery replacement kits.
Is there an answer to this question: What kind of battery does the iPod use?

Answer: lithium-ion

Question: Though many of the events were outside the traditional time-period of the Middle Ages, the end of the unity of the Western Church (the Protestant Reformation), was one of the distinguishing characteristics of the medieval period. The Catholic Church had long fought against heretic movements, but during the Late Middle Ages, it started to experience demands for reform from within. The first of these came from Oxford professor John Wycliffe in England. Wycliffe held that the Bible should be the only authority in religious questions, and he spoke out against transubstantiation, celibacy and indulgences. In spite of influential supporters among the English aristocracy, such as John of Gaunt, the movement was not allowed to survive. Though Wycliffe himself was left unmolested, his supporters, the Lollards, were eventually suppressed in England.
Is there an answer to this question: Which Catholic practices did Wycliffe speak out for?

Answer: unanswerable
