TASK DEFINITION: In this task, you're given a question, along with a context passage. The passage will not have a direct answer to the question, but can include some information and a clue for the answer. Assuming you can only obtain information about one entity in the passage, your job is to determine whether information from the passage can be used to answer the question. Indicate your choice as `a` for Yes or `b` for No.
PROBLEM: Question: What is the maximum length of the species that is known to prey on the crossback stingaree? Passage:The broadnose sevengill shark (Notorynchus cepedianus) is known to prey on the crossback stingaree. When threatened, this ray raises its tail warningly above its body in a scorpion-like fashion. Parasites documented from this species include a tapeworm in the genus Acanthobothrium, and the monogenean Calicotyle urolophi. Like other stingrays, the crossback stingaree is aplacental viviparous: when the developing embryos exhaust their supply of yolk, their mother provisions them with nutrient-rich histotroph ("uterine milk") through specialized extensions of the uterine epithelium called "trophonemata". Females produce litters of 1–4 pups every other year. Embryonic development proceeds rapidly over a six-month period, though the total gestation period may be much longer if there is a period of dormancy for the eggs after fertilization, as has been reported in other stingarees. Off Tasmania, large estuaries such as at the mouth of the River Derwent serve as nursery areas.

PROBLEM: Question: Was the man who consecrated Richardson in 1879 older than 50 at the time? Passage:Alfred Spencer Richardson was consecrated on 22 June 1879 in the Reformed Episcopal Church in Philadelphia, USA by William Rufus Nicholson, a bishop of the Reformed Episcopal Church, USA. WR Nicholson was consecrated for the Protestant Episcopal Church, USA on 24 February 1876 by Charles Edward Cheney who was consecrated (14 December 1873) by George David Cummins, American Episcopal assistant bishop of Kentucky, USA, and who was consecrated (15 November 1866) by John Henry Hopkins, Episcopal bishop of Vermont, USA. The line of succession to Hopkins is traceable from William Sancroft (enthroned archbishop of Canterbury, 1678) via Thomas White (bishop of Peterborough, England), George Hickes (assistant bishop of Thetford, England), James Gadderar (bishop of Aberdeen, Scotland), Thomas Rattray (bishop of Dunkeld, Scotland), William Falconer (or Falconar) (bishop of Caithness, Scotland), Robert Kilgour (bishop of Aberdeen, Scotland), Samuel Seabury (bishop of Connecticut, USA), Thomas Clagett (bishop of Maryland, USA), Edward Bass (bishop of Massachusetts, USA), Abraham Jarvis (bishop of Connecticut, USA), Alexander Viets Griswold (bishop of Eastern Diocese, USA) who in 1832 consecrated Hoskins.

PROBLEM: Question: How big was Montclair the year DeGolyer went to work in New York City? Passage:DeGolyer opened a petroleum geology consultancy in 1914, moving to Montclair, New Jersey to work in New York City in 1916. In 1919, while working as a consultant to the British entrepreneur Lord Cowdray, DeGolyer negotiated the sale of the El Aguila company to Royal Dutch Shell. In the same year, DeGolyer organized the formation of the Rycade Oil Company as well as the Amerada Petroleum Corporation for Lord Cowdray, rising to become general manager, president, and chairman from 1929 to 1932 DeGolyer left the firm in 1932, but remained with Rycade, which was established to explore salt dome oil deposits through 1941. As a geophysical consultant with Rycade, DeGolyer made the first torsion balance survey in the United States at the Spindletop oilfield. An oilfield found by DeGolyer on behalf of Rycade at Nash, Texas was the first oilfield anywhere to be discovered using geophysics. From 1925 DeGolyer established the Geophysical Research Corporation as a subsidiary of Amerada to develop reflection seismology techniques originated by J. Clarence Karcher and Eugene McDermott, leaving in 1932 to move to Dallas, Texas. DeGolyer provided financial support for the 1930 establishment of GRC's successor, Geophysical Service Incorporated. GSI went on to spin off Texas Instruments. In 1936 with Lewis MacNaughton, DeGolyer established the petroleum exploration consulting firm DeGolyer and MacNaughton, and Core Laboratories, Incorporated the same year to provide drilling core and fluids analysis. DeGolyer was also associated with the Atlatl Royalty Company from 1932 to 1950 and the Felmont Corporation in 1934. In 1956 he established Isotopes, Incorporated to provide radioactive isotopes for oilfield and industrial purposes.
