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: Question: When did the operation during which the 704th dropped supplies to allied troops near Nijmegen begin? Passage: The group was occasionally diverted from strategic missions to carry out air support and interdiction missions. It supported Operation Overlord, the invasion of Normandy by attacking transportation targets, including bridges, along with airfields and strong points in France. On D Day, the squadron and the rest of the 446th Group led the first heavy bomber mission of the day. The 446th aided ground forces at Caen and Saint-Lo during July by hitting bridges, gun batteries, and enemy troops. During Operation Market Garden, the attempt to seize a bridgehead across the Rhine in the Netherlands, the 704th dropped supplies to allied troops near Nijmegen. It struck lines of communications during the Battle of the Bulge. During Operation Varsity in March 1945, it supplied ground and airborne troops near Wesel. The squadron flew its last combat mission on 25 April 1945 against Salzburg, Austria. The group had flown 273 missions and had lost 58 aircraft during the war,
.
Example solution: b
Example explanation: The passage describes the 704th's actions during Operation Market Garden so only information about the operation is needed.

Problem: Question: Which mountains the Dyke climbed were the highest? Passage:In his spare time during his working life, he climbed the Cape Peninsula mountains, the Hottentots-Holland mountains, and nearby ranges, all of which are spectacular examples of Fynbos, including Peninsula Granite Fynbos, Peninsula Sandstone Fynbos and a number of related biomes. Later, when the railway administration moved to Johannesburg, he continued his explorations in various parts of the Drakensberg mountains, as well as on visits to Lesotho. On such excursions he collected avidly and sent specimens to Dr Rudolf Marloth. He extended his explorations to other regions as well; for example, while climbing the Cockscomb Mountains in the Winterberg range near Uitenhage he discovered a hitherto unrecognised species of Protea, later named Protea dykei Phill (now seen as a synonym of Protea rupicola). On Matroosberg in the Hex River Mountains, he discovered a new species of "everlasting", flowers that in those days were generally included in the genus Helichrysum. That species was described by Harry Bolus under the name Helichrysum dykei Bolus. The genus has since been split however, and the species has been assigned to another genus, as Syncarpha dykei (Bolus) B. Nord. Dyke's name also appears in the names of Erica dykei L. Bolus (= Erica thodei Gilg) and Lessertia dykei L. Bolus.
