Q: Question: "The CDs are sometimes what that allows it to become defective?" Context: "CDs are susceptible to damage during handling and from environmental exposure. Pits are much closer to the label side of a disc, enabling defects and contaminants on the clear side to be out of focus during playback. Consequently, CDs are more likely to suffer damage on the label side of the disc. Scratches on the clear side can be repaired by refilling them with similar refractive plastic or by careful polishing. The edges of CDs are sometimes incompletely sealed, allowing gases and liquids to corrode the metal reflective layer and to interfere with the focus of the laser on the pits. The fungus Geotrichum candidum, found in Belize, has been found to consume the polycarbonate plastic and aluminium found in CDs." Answer:
A: The edges of CDs are sometimes incompletely sealed, allowing gases and liquids to corrode the metal reflective layer and to interfere with the focus of the laser on the pits

Q: Question: "When did large scale production of such vehicles begin?" Context: "The Hummers that Schwarzenegger bought 1992 are so large each weighs 6,300 lb (2,900 kg) and is 7 feet (2.1 m) wide that they are classified as large trucks, and U.S. fuel economy regulations do not apply to them. During the gubernatorial recall campaign he announced that he would convert one of his Hummers to burn hydrogen. The conversion was reported to have cost about US$21,000. After the election, he signed an executive order to jump-start the building of hydrogen refueling plants called the California Hydrogen Highway Network, and gained a U.S. Department of Energy grant to help pay for its projected US$91,000,000 cost. California took delivery of the first H2H (Hydrogen Hummer) in October 2004." Answer:
A: After the election

Q: Question: "what kind of prop did she use for her character?" Context: "In September 1993, Madonna embarked on The Girlie Show World Tour, in which she dressed as a whip-cracking dominatrix surrounded by topless dancers. In Puerto Rico she rubbed the island's flag between her legs on stage, resulting in outrage among the audience. In March 1994, she appeared as a guest on the Late Show with David Letterman, using profanity that required censorship on television, and handing Letterman a pair of her panties and asking him to smell it. The releases of her sexually explicit films, albums and book, and the aggressive appearance on Letterman all made critics question Madonna as a sexual renegade. Critics and fans reacted negatively, who commented that "she had gone too far" and that her career was over." Answer:
A: whip

Q: Question: "Were there fewer candidates in 1849 or 1839?" Context: "Internal party disunity compounded the difficulty of identifying lawmakers who might have informally functioned as a minority leader. For instance, "seven of the fourteen speakership elections from 1834 through 1859 had at least twenty different candidates in the field. Thirty-six competed in 1839, ninety-seven in 1849, ninety-one in 1859, and 138 in 1855." With so many candidates competing for the speakership, it is not at all clear that one of the defeated lawmakers then assumed the mantle of "minority leader." The Democratic minority from 1861 to 1875 was so completely disorganized that they did not "nominate a candidate for Speaker in two of these seven Congresses and nominated no man more than once in the other five. The defeated candidates were not automatically looked to for leadership."" Answer:
A:
1839
