In this task, you're given a question, along with three passages, 1, 2, and 3. Your job is to determine which passage can be used to answer the question by searching for further information using terms from the passage. Indicate your choice as 1, 2, or 3.
Q: Question: How many years old was William FitzOxbern when the Priory Church was founded? Passage 1:The highway continues at the Rhode Island border at Rhode Island Route 24 and meets Interstate 195 in Fall River. It briefly runs concurrently with I-195 east (for less than a mile), then exits the interstate and travels north, merging with Route 79 at Exit 7 in northern Fall River. Routes 24 and 79 run concurrently northward until Exit 9 (Assonet). At this point, Route 79 exits the freeway and heads northeast. Route 24 continues north, intersecting the northern end of the Taunton-New Bedford Expressway (Route 140) in Taunton, and Interstate 495 in Raynham. The highway continues north through the city of Brockton and into Randolph, where Route 24 ends at a split junction with Interstate 93. This section of I-93 from Braintree to its junction with I-95 is frequently, yet erroneously, referred to by its former designation of Route 128. This designation was removed from I-93 in 1989, when the roadway obtained the additional designation of U.S. Route 1, although this is not shown on exit signs from Route 24. The route is officially 40.9 miles in length, however, mileposts continue up to 41.2 on the Exit 21B ramp to I-93 south.
Passage 2:McMahon contributed to the understanding of retinal neurophysiology alongside his post-doctoral mentor, John E. Dowling. His early research focused on ion channels that mediate transmission at electrical and glutamatergic synapses and the modulatory effects of dopamine and nitric oxide on retinal synapse networks. Through studies with zebrafish he discovered that the neurotransmitter dopamine decreases the electrical coupling within horizontal cells. Further research showed that it was the increase of cAMP within the cell resulting from dopamine binding to AMPA receptor that led to this decrease in coupling. McMahon and his colleagues also demonstrated that exogenous nitric oxide and zinc can modulate AMPA receptor mediated synaptic transmission at gap junctions in hybrid bass retinal neurons.
Passage 3:It was founded around 1072 as a Benedictine priory by William FitzOsbern and his son Roger de Breteuil, 2nd Earl of Hereford. FitzOsbern had been granted the Lordship of Striguil by his second cousin King William in gratitude for his support in the Norman conquest of England, and was responsible for starting the building of a new castle overlooking the River Wye on the border with the kingdoms of Wales. At the same time he established a nearby monastic cell, so as to collect rent from the lands within Gwent which he had granted to his home Priory of Cormeilles in Normandy. By the early 12th century, the monastic establishment, on a ridge overlooking the river about 300 metres from the castle, had the status of an alien priory in its own right, though it probably never held more than about 12 monks. It superseded an earlier Augustinian priory located about 2km away, which was dedicated to the Welsh saint Cynfarch (or St. Kingsmark), a disciple of St. Dyfrig.
