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.

Input: Consider Input: Question: What is Lorraine Copeland's field of study? Passage:It was first studied by Lorraine Copeland and Peter Wescombe in 19651966. A wide variety of materials were recovered from the site and its immediate area that are now held in the Saint Joseph University in Beirut. Stone tools from the surface included numerous short, wide, sickle blades with fine denticulation or nibbling along with tanged arrowheads, scrapers, chisels, axes, burins, obsidian and a small green stone axe. Pottery resembled middle periods at Byblos and coloured similar to at Ard Tlaili with red or black washes. Both fine and coarse shards were found of jars with a variety of collared and flared necks and flat bases along with bow rims such as those found at Jericho. Vessels were decorated with stabbed and incised designs, finger pressed around the rim and smoothed by hand or with straw. A painted lattice pattern was detected on at least one piece. Comparisons were made with middle and late Neolithic periods at Byblos showing inhabitation from several phases. The site was also used in Bronze Age and Classical times and material from these phases has been found over a wide area around the site.

Input: Consider Input: Question: What is the average temperature of the body of water where the frontal low developed? Passage:A tropical disturbance moved westward offshore Nicaragua and was declared Tropical Depression Twenty-Four on October15.. During the early afternoon of the next day, ship reports indicated the formation of a tropical depression close to land. The cyclone moved at a quick pace towards the west-northwest south of a warm-core ridge. Early on the morning on October16, Roslyn became a tropical storm. By the morning of the October17, Roslyn had developed into a hurricane south of Acapulco. A vigorous upper trough was deepening offshore Baja California, and Roslyn began to re-curve within a few hundred miles of Manzanillo. The system struck Mazatlan as a marginal hurricane on October20. The low-level center rapidly dissipated, although a frontal low developed in the western Gulf of Mexico, which moved over southeastern Texas and later through the Mississippi Valley. The original upper-level circulation maintained its northeast movement, bringing rainfall to the Southeastern United States.

Input: Consider Input: Question: Were the monte Carlo Rally and the Isle of Man TT in the same country? Passage:Glen Kidston competed in numerous motor races including the Monte Carlo Rally, Isle of Man TT motorcycle races, and Shelsley Walsh hillclimb. As a naval amateur he raced a Sunbeam motorcycle up the hill climb in Hong Kong and conducted speed trials on the sands, bringing the bike with him in his submarine which was patrolling the China Station. Kidston entered the 1929 Irish Grand Prix Eireann Cup at Phoenix Park but was narrowly beaten by the Alfa Romeo of former Russian Imperial Guard officer Boris Ivanowski. This was achieved at the expense of Britons Glen Kidston and Henry Birkin, whose Bentleys were second and third respectively. He also owned and raced the first Bugatti in the UK and entered the Le Mans 24-hour race in 1929 and 1930. On the second occasion he won the race, driving a Bentley Speed Six in partnership with Woolf Barnato, with the Bentley team delivering a 1-2-3-4 victory.
