In this task, you're given a question, along with a context passage which has extra information available on certain terms mentioned in it, i.e., the proper nouns in the passage. Your job is to determine whether information from more than one term is needed to answer the question. Indicate your choice as `a` for Yes or `b` for No.

Example Input: Question: Was the route updated before The Weavers' Triangle Visitor Centre was built? Passage:The route is described in a series of six sectional leaflets, updated in 2008, which are available from Burnley Tourist Information Centre. The first section begins at the Manchester Road canal bridge (where the Weavers' Triangle Visitor Centre is located), and follows the towpath of the Leeds and Liverpool Canal over the Burnley Embankment to Thompson Park. It then follows the River Brun through Bank Hall Park and past Heasandford House where it joins the route of the Brontë Way out of Burnley, almost to Lea Green Reservoir. It then passes the ruined Extwistle Hall and over the River Don to Queen Street Mill Textile Museum in Harle Syke. The second section crosses Todmorden Road, passing a number of farms and over Thursden brook. It then follows the road up the Thursden valley and crosses into West Yorkshire, descending to Widdop Reservoir. Joining the Mary Towneley Loop section of the Pennine Bridleway at the Gorpe track, it moves back into Lancashire and past Hurstwood Reservoir to the Elizabethan hamlet of Hurstwood.

Example Input: Question: How many years did the king rule that made Wemyss an Earl? Passage:John Wemyss was knighted in 1618 and created a Baronet of Nova Scotia in 1625. This included a charter to the barony of New Wemyss in that province of Canada. He was later advanced to the title of Earl of Wemyss and the patent was presented to him at Dunfermline personally by Charles I of England. John Wemyss was also a Privy Councillor, High Commissioner to the General Assembly of the Church of Scotland, and one of the Committee of the Estates. John Wemyss died in 1649 and was succeeded by his only son, David Wemyss, 2nd Earl of Wemyss. David Wemyss, the second earl spent a lifetime nurturing the resources of his estate, in particular his salt and coal mines. He also built a large harbour at Methil, Fife and greatly extended Wemyss Castle where he entertained Charles II of England in 1650 and 1651. He died in 1679 and was predeceased by his son so the estates fell to his daughter, Margaret Wemyss, 3rd Countess of Wemyss. Margaret married her cousin, James Wemyss, Lord Burntisland. Their son was David Wemyss, 4th Earl of Wemyss who succeeded his mother in 1705.

Example Input: Question: Who was the head of Lawrence Livermore National Laboratory when a group created a metallic hydrogen? Passage:In March 1996, a group of scientists at Lawrence Livermore National Laboratory reported that they had serendipitously produced the first identifiably metallic hydrogen for about a microsecond at temperatures of thousands of kelvins, pressures of over , and densities of approximately . The team did not expect to produce metallic hydrogen, as it was not using solid hydrogen, thought to be necessary, and was working at temperatures above those specified by metallization theory. Previous studies in which solid hydrogen was compressed inside diamond anvils to pressures of up to , did not confirm detectable metallization. The team had sought simply to measure the less extreme electrical conductivity changes they expected. The researchers used a 1960s-era light-gas gun, originally employed in guided missile studies, to shoot an impactor plate into a sealed container containing a half-millimeter thick sample of liquid hydrogen. The liquid hydrogen was in contact with wires leading to a device measuring electrical resistance. The scientists found that, as pressure rose to , the electronic energy band gap, a measure of electrical resistance, fell to almost zero. The band-gap of hydrogen in its uncompressed state is about , making it an insulator but, as the pressure increases significantly, the band-gap gradually fell to . Because the thermal energy of the fluid (the temperature became about due to compression of the sample) was above , the hydrogen might be considered metallic.
