Input: Read this: Dell advertisements have appeared in several types of media including television, the Internet, magazines, catalogs and newspapers. Some of Dell Inc's marketing strategies include lowering prices at all times of the year, free bonus products (such as Dell printers), and free shipping to encourage more sales and stave off competitors. In 2006, Dell cut its prices in an effort to maintain its 19.2% market share. This also cut profit-margins by more than half, from 8.7 to 4.3 percent. To maintain its low prices, Dell continues to accept most purchases of its products via the Internet and through the telephone network, and to move its customer-care division to India and El Salvador.
Question: What year did Dell up its prices to keep its market share?

Output: unanswerable

Input: Read this: The hole walls for boards with two or more layers can be made conductive and then electroplated with copper to form plated-through holes.  These holes electrically connect the conducting layers of the PCB. For multi-layer boards, those with three layers or more, drilling typically produces a smear of the high temperature decomposition products of bonding agent in the laminate system. Before the holes can be plated through, this smear must be removed by a chemical de-smear process, or by plasma-etch. The de-smear process ensures that a good connection is made to the copper layers when the hole is plated through. On high reliability boards a process called etch-back is performed chemically with a potassium permanganate based etchant or plasma. The etch-back removes resin and the glass fibers so that the copper layers extend into the hole and as the hole is plated become integral with the deposited copper.
Question: What do the hole walls in two-layer PCBs have to be before they can be electroplated?

Output: conductive


Input: Read this: Besides the schism, the western church was riven by theological controversies, some of which turned into heresies. John Wycliffe (d. 1384), an English theologian, was condemned as a heretic in 1415 for teaching that the laity should have access to the text of the Bible as well as for holding views on the Eucharist that were contrary to church doctrine. Wycliffe's teachings influenced two of the major heretical movements of the later Middle Ages: Lollardy in England and Hussitism in Bohemia. The Bohemian movement initiated with the teaching of Jan Hus, who was burned at the stake in 1415 after being condemned as a heretic by the Council of Constance. The Hussite church, although the target of a crusade, survived beyond the Middle Ages. Other heresies were manufactured, such as the accusations against the Knights Templar that resulted in their suppression in 1312 and the division of their great wealth between the French King Philip IV (r. 1285–1314) and the Hospitallers.
Question: Of what nationality was John Wycliffe?
