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: How old was Jennie Jerome when her granddaughter Lady Eden was born? Passage:Lady Eden was born in 1920, the daughter of Major Jack Spencer-Churchill (1880–1947), the younger brother of Winston Churchill, by his marriage to Lady Gwendoline ("Goonie") Bertie (1885–1941), a daughter of the 7th Earl of Abingdon, who had been married in 1908. She is thus a niece of Winston Churchill, who was Prime Minister during the Second World War, and a granddaughter of Lord Randolph Churchill, Chancellor of the Exchequer 1886–87, and his wife the American society beauty Jennie Jerome. Her paternal great-grandfather was the 7th Duke of Marlborough, and her maternal great-great-grandfather the 3rd Marquess of Londonderry, half-brother of the 2nd Marquess, who, as Viscount Castlereagh was Foreign Secretary during the Congress of Vienna of 1815 that followed the Napoleonic Wars.

Example Input: Question: How many parties took part in the 1988 Knesset elections contested by the NRP? Passage:The Meimad movement was founded on 1 June 1988 by Rabbi Yehuda Amital, and included former National Religious Party Knesset member Yehuda Ben-Meir. It contested the November 1988 Knesset elections, receiving 0.7% of the vote and failing to cross the 1% electoral threshold. Eleven years later, a political arm was established, and joined the One Israel alliance that won the Knesset elections that year. Meimad received one seat, taken by Michael Melchior. It gained a second when Yehuda Gilad replaced Maxim Levy in 2002. Tova Ilan also represented Meimad in the Knesset for a brief spell in 2006, after several other Labour MKs resigned. It attracted moderates among immigrants from the English-speaking world, including Shimon Glick.

Example Input: Question: Is the king who conquered England older than his half-brother who he granted the Studland? Passage:The first records of inhabitants on Brownsea Island occurred in the 9th century, when a small chapel and hermitage were built by monks from Cerne Abbey near Dorchester. The chapel was dedicated to St Andrew and the only resident of the island was a hermit, who may have administered to the spiritual welfare of sailors passing through Poole Harbour. In 1015, Canute led a Viking raid to the harbour and used Brownsea as a base to sack Wareham and Cerne Abbey. In the 11th century the owner of the island was Bruno, who was Lord of the Manor of Studland. Following his invasion of England, William the Conqueror gave Studland, which included Brownsea, to his half-brother, Robert de Mortain. In 1154, King Henry II granted the Abbot of Cerne the right of wreck for the island and the abbey continued to control the interests of Brownsea for the following 350 years.
