Input: Read this: Under the Bretton Woods system established after World War II, the value of gold was fixed to $35 per ounce, and the value of the U.S. dollar was thus anchored to the value of gold. Rising government spending in the 1960s, however, led to doubts about the ability of the United States to maintain this convertibility, gold stocks dwindled as banks and international investors began to convert dollars to gold, and as a result the value of the dollar began to decline. Facing an emerging currency crisis and the imminent danger that the United States would no longer be able to redeem dollars for gold, gold convertibility was finally terminated in 1971 by President Nixon, resulting in the "Nixon shock".
Question: In which year was gold convertability terminated?

Output: 1971

Input: Read this: The football team plays at Ryan Field (formerly known as Dyche Stadium); the basketball, wrestling, and volleyball teams play at Welsh-Ryan Arena. Northwestern's athletic teams are nicknamed the Wildcats. Before 1924, they were known as "The Purple" and unofficially as "The Fighting Methodists." The name Wildcats was bestowed upon the university in 1924 by Wallace Abbey, a writer for the Chicago Daily Tribune who wrote that even in a loss to the University of Chicago, "Football players had not come down from Evanston; wildcats would be a name better suited to [Coach Glenn] Thistletwaite's boys." The name was so popular that university board members made "wildcats" the official nickname just months later. In 1972, the student body voted to change the official nickname from "Wildcats" to "Purple Haze" but the new name never stuck.
Question: What name did the student body unsuccessfully try to rename the Wildcats in 1970?

Output: unanswerable

Input: Read this: Birds that employ many strategies to obtain food or feed on a variety of food items are called generalists, while others that concentrate time and effort on specific food items or have a single strategy to obtain food are considered specialists. Birds' feeding strategies vary by species. Many birds glean for insects, invertebrates, fruit, or seeds. Some hunt insects by suddenly attacking from a branch. Those species that seek pest insects are considered beneficial 'biological control agents' and their presence encouraged in biological pest control programs. Nectar feeders such as hummingbirds, sunbirds, lories, and lorikeets amongst others have specially adapted brushy tongues and in many cases bills designed to fit co-adapted flowers. Kiwis and shorebirds with long bills probe for invertebrates; shorebirds' varied bill lengths and feeding methods result in the separation of ecological niches. Loons, diving ducks, penguins and auks pursue their prey underwater, using their wings or feet for propulsion, while aerial predators such as sulids, kingfishers and terns plunge dive after their prey. Flamingos, three species of prion, and some ducks are filter feeders. Geese and dabbling ducks are primarily grazers.
Question: What type of birds have specially adapted brushy tongues?

Output: Nectar feeders
