Input: Read this: Unpopulated boards are usually bare-board tested for "shorts" and "opens". A short is a connection between two points that should not be connected. An open is a missing connection between points that should be connected. For high-volume production a fixture or a rigid needle adapter is used to make contact with copper lands on the board. Building the adapter is a significant fixed cost and is only economical for high-volume or high-value production. For small or medium volume production flying probe testers are used where test probes are moved over the board by an XY drive to make contact with the copper lands. The CAM system instructs the electrical tester to apply a voltage to each contact point as required and to check that this voltage appears on the appropriate contact points and only on these.
Question: A long is a connection between what?

Output: unanswerable


Input: Read this: Alternatives to pesticides are available and include methods of cultivation, use of biological pest controls (such as pheromones and microbial pesticides), genetic engineering, and methods of interfering with insect breeding. Application of composted yard waste has also been used as a way of controlling pests. These methods are becoming increasingly popular and often are safer than traditional chemical pesticides. In addition, EPA is registering reduced-risk conventional pesticides in increasing numbers.
Question: How is genetic engineering compared to conventional crop growing methods?

Output: unanswerable


Input: Read this: The early settlement was often subject to attack from sea and land, including periodic assaults from Spain and France (both of whom contested England's claims to the region), and pirates. These were combined with raids by Native Americans, who tried to protect themselves from so-called European "settlers," who in turn wanted to expand the settlement. The heart of the city was fortified according to a 1704 plan by Governor Johnson. Except those fronting Cooper River, the walls were largely removed during the 1720s.
Question: Which group raided the settlement as a means to protect themselves from police?

Output: unanswerable


Input: Read this: The new interiors sought to recreate an authentically Roman and genuinely interior vocabulary. Techniques employed in the style included flatter, lighter motifs, sculpted in low frieze-like relief or painted in monotones en camaïeu ("like cameos"), isolated medallions or vases or busts or bucrania or other motifs, suspended on swags of laurel or ribbon, with slender arabesques against backgrounds, perhaps, of "Pompeiian red" or pale tints, or stone colours. The style in France was initially a Parisian style, the Goût grec ("Greek style"), not a court style; when Louis XVI acceded to the throne in 1774, Marie Antoinette, his fashion-loving Queen, brought the "Louis XVI" style to court.
Question: Who brought Louis XVI style to the court?

Output:
Marie Antoinette
