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 the architect who designed part of the Marienlyst Castle when it was built? Passage:Hans van Steenwinckel, the royal architect, designed and built the original pavilion and parterre garden in 1587, for King Frederick II of Denmark. The royal estate was then purchased in 1758 by Count Adam Gottlob Moltke, who completely changed the original pavilion and garden with the help of French architect Nicolas-Henri Jardin between 1759 and 1763. The additions led to its present-day architectural structure and façade. Jardin also redesigned the original parterre gardens, changing them to a larger, more modern garden à la française design, with symmetrical hedges, avenues, fountains and mirror ponds. Within the castle wall boundaries, these elegant garden grounds remain to a large extent intact, but outside, much of the garden has been lost, including the most renowned romantic landscape garden in Denmark, designed by Johan Ludvig Mansa in the 1790s. This was mostly due to the sale of much of the original property by the Helsingør municipality which had purchased the entire Marienlyst estate at auction in 1851. One of the lot purchasers was J.S. Nathanson, who in 1859 built Hotel Marienlyst, the first luxury hotel in Helsingør, named after the castle.

Example Input: Question: How big is the National Park that the Yellowstone River flows northward through? Passage:The river rises in northwestern Wyoming in the Absaroka Range, on the Continental Divide in southwestern Park County. The river starts where the North Fork and the South Fork of the Yellowstone River converge. The North Fork, the larger of the two forks, flows from Younts Peak. The South Fork flows from the southern slopes of Thorofare Mountain. The Yellowstone River flows northward through Yellowstone National Park, feeding and draining Yellowstone Lake, then dropping over the Upper and Lower Yellowstone Falls at the head of the Grand Canyon of the Yellowstone within the confines of the park. After passing through the Black Canyon of the Yellowstone downstream of the Grand Canyon, the river flows northward into Montana between the northern Absaroka Range and the Gallatin Range in Paradise Valley. The river emerges from the mountains near the town of Livingston, where it turns eastward and northeastward, flowing across the northern Great Plains past the city of Billings.

Example Input: Question: Who was in charge of the Suez Canal Company when it was seized by the Egyptian government? Passage:Nehru's foreign policy was the inspiration of the Non-Aligned Movement, of which India was a co-founder. Nehru maintained friendly relations with both the United States and the Soviet Union, and encouraged the People's Republic of China to join the global community of nations. In 1956, when the Suez Canal Company was seized by the Egyptian government, an international conference voted 18–4 to take action against Egypt. India was one of the four backers of Egypt, along with Indonesia, Sri Lanka, and the USSR. India had opposed the partition of Palestine and the 1956 invasion of the Sinai by Israel, the United Kingdom and France, but did not oppose the Chinese direct control over Tibet, and the suppression of a pro-democracy movement in Hungary by the Soviet Union. Although Nehru disavowed nuclear ambitions for India, Canada and France aided India in the development of nuclear power stations for electricity. India also negotiated an agreement in 1960 with Pakistan on the just use of the waters of seven rivers shared by the countries. Nehru had visited Pakistan in 1953, but owing to political turmoil in Pakistan, no headway was made on the Kashmir dispute.
