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.

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.

Question: What is the scientific name for studying why there are foreign materials in a bee's honey? Passage:Anemophilous pollen grains are light and non-sticky, so that they can be transported by air currents. They are typically in diameter, although the pollen grains of Pinus species can be much larger and much less dense. Anemophilous plants possess well-exposed stamens so that the pollens are exposed to wind currents and also have large and feathery stigma to easily trap airborne pollen grains. Pollen from anemophilous plants tends to be smaller and lighter than pollen from entomophilous ones, with very low nutritional value to insects. However, insects sometimes gather pollen from staminate anemophilous flowers at times when higher-protein pollens from entomophilous flowers are scarce. Anemophilous pollens may also be inadvertently captured by bees' electrostatic field. This may explain why, though bees are not observed to visit ragweed flowers, its pollen is often found in honey made during the ragweed floral bloom. Other flowers that are generally anemophilous are observed to be actively worked by bees, with solitary bees often visiting grass flowers, and the larger honeybees and bumblebees frequently gathering pollen from corn tassels and other grains.

Question: What is the seating capacity of the stadium where Cooper's pass led to a winning goal for Watford during the semi-finals of the 1984 FA Cup? Passage:He progressed through the youth system at Plymouth Argyle to make his first team debut in November 1979 against Colchester United. Having established himself as a regular on the left side of midfield, he scored his first of 18 goals for the club in January 1981 against Millwall. Cooper became one of the youngest players to captain a side in the Football League, at the age of 22, when he was given the armband by Johnny Hore, the club's manager and a former Argyle player. He helped the club reach the semi-finals of the FA Cup in 1984, leading the side out against Watford at Villa Park, but his stray pass led to the winning goal for their opponents. He lost his place in the side the following year before being converted into a full back, and he was a key member of Dave Smith's team that gained promotion to the Second Division in 1986.
