Example Input: Passage: An electromagnetic wave refractor in some aperture antennas is a component which due to its shape and position functions to selectively delay or advance portions of the electromagnetic wavefront passing through it. The refractor alters the spatial characteristics of the wave on one side relative to the other side. It can, for instance, bring the wave to a focus or alter the wave front in other ways, generally in order to maximize the directivity of the antenna system. This is the radio equivalent of an optical lens. Question: What is used to allow one to control the function of wave fronts moving through an antenna?
Example Output: selectively delay

Example Input: Passage: The "snug", sometimes called the smoke room, was typically a small, very private room with access to the bar that had a frosted glass external window, set above head height. A higher price was paid for beer in the snug and nobody could look in and see the drinkers. It was not only the wealthy visitors who would use these rooms. The snug was for patrons who preferred not to be seen in the public bar. Ladies would often enjoy a private drink in the snug in a time when it was frowned upon for women to be in a pub. The local police officer might nip in for a quiet pint, the parish priest for his evening whisky, or lovers for a rendezvous. Question: What was the relationship between the price of beer in the smoke room versus the rest of the bar?
Example Output: higher

Example Input: Passage: The English language has been official in the state of Oklahoma since 2010. The variety of North American English spoken is called Oklahoma English, and this dialect is quite diverse with its uneven blending of features of North Midland, South Midland, and Southern dialects. In 2000, 2,977,187 Oklahomans—92.6% of the resident population five years or older—spoke only English at home, a decrease from 95% in 1990. 238,732 Oklahoma residents reported speaking a language other than English in the 2000 census, about 7.4% of the total population of the state. Spanish is the second most commonly spoken language in the state, with 141,060 speakers counted in 2000. The next most commonly spoken language is Cherokee, with about 22,000 speakers living within the Cherokee Nation tribal jurisdiction area of eastern Oklahoma. Cherokee is an official language in the Cherokee Nation tribal jurisdiction area and in the United Keetoowah Band of Cherokee Indians. Question: How many Oklahomans speak only English at home, as of 2000?
Example Output:
2,977,187
