In this task, you're given a question, a context passage, and four options which are terms from the passage. After reading a passage, you will get a brief understanding of the terms. Your job is to determine by searching and reading further information of which term you can answer the question. Indicate your choice as 'a', 'b', 'c', or 'd'. If you think more than one option is plausible, choose the more probable option to help you answer the question.

Q: Question: How long had Darrell Royal been working as a head coach the year he learned about the wishbone offense? Passage:In 1968, Texas head coach Darrell Royal and his offensive coordinator Emory Bellard introduced what would become known as the wishbone offense. The wishbone was derived from the Split-T offense run at Oklahoma under Bud Wilkinson. In the formation, the quarterback lines up with a fullback and two tailbacks behind him, and on any play may keep the ball, hand off to the fullback, or pitch to a tailback. From the time Bryant arrived at Alabama through the 1970 season, the Crimson Tide ran a pro-style offense. By 1969, Bryant began to recruit larger linemen and tailbacks, and after a pair of six win seasons in 1969 and 1970, Bryant saw the success of the wishbone for the Longhorns and decided to implement the offense for the 1971 season. In spring 1971, Alabama assistants Mal Moore and Jimmy Sharpe traveled to Austin where they saw first hand how the wishbone operated during Texas' final week of spring practice.

Q: Question: How high is the gamma radiation from nuclear fuel? Passage:The nuclear fuel elements were made of refractory ceramic based on beryllium oxide, with enriched uranium dioxide as fuel and small amount of zirconium dioxide for structural stability. The fuel elements were hollow hexagonal tubes about long with distance between the outer parallel planes, with inside diameter of . They were manufactured by high-pressure extruding of the green compact, then sintering almost to its theoretical density. The core consisted of 465,000 individual elements stacked to form 27,000 airflow channels; the design with small unattached elements reduced problems related with thermal stresses. The elements were designed for average operation temperature of ; the autoignition temperature of the reactor base plates was only 150 °C higher. The neutron flux was calculated to be 9×10 neutrons/(cm·s) in the aft and 7×10 neutrons/(cm·s) in the nose. The gamma radiation level was fairly high due to the lack of shielding; radiation hardening for the guidance electronics had to be designed.

Q: Question: What happened to the building that spanned 8 or 9 acres? Passage:William Briwere was granted the lordship of the Manor of Bridgwater by John of England in 1201, and founded Bridgwater Friary. Through Briwere's influence, King John granted three charters in 1200; for the construction of Bridgwater Castle, for the creation of a borough, and for a market. Bridgwater Castle was a substantial structure built in Old Red Sandstone, covering a site of 8 or 9 acres (32,000 to 36,000 m²). A tidal moat, up to wide in places, flowed about along the line of the modern thoroughfares of Fore Street and Castle Moat, and between Northgate and Chandos Street. The main entrance opposite the Cornhill was built with a pair of adjacent gates and drawbridges. In addition to a keep, located at the south-east corner of what is now King Square, documents show that the complex included a dungeon, chapel, stables and a bell tower. Built on the only raised ground in the town, the castle controlled the crossing of the town bridge. A thick portion of the castle wall and water gate can still be seen on West Quay, and the remains of a wall of a building that was probably built within the castle can be viewed in Queen Street. The foundations of the tower forming the north-east corner of the castle are buried beneath Homecastle House. William Briwere also founded St John's hospital which, by the time of the Dissolution of the Monasteries under Henry VIII, was worth the substantial sum of almost 121 pounds, as well as starting the construction of the town's first stone bridge. William Briwere also went on to found the Franciscan Bridgwater Friary in the town.
