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.

Let me give you an 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-Lô 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,
.
The answer to this example can be: b
Here is why: The passage describes the 704th's actions during Operation Market Garden so only information about the operation is needed.

Question: How many years did the Batavian Revolution take place? Passage:In 1795 Fijnje returned to the Netherlands (after the Batavian Revolution), after which he became a member of the commité van waakzaamheid (the Batavian version of the French Committee of Public Safety), chaired the Provisional Representatives of the People of Holland for a while. and - together with Samuel Iperusz Wiselius and professor Theodorus van Kooten - served on the committee for the liquidation of the VOC. In all these posts he took radical viewpoints, but he also enjoyed himself thoroughly. On 22 January 1798, he performed a Coup d'état with general Herman Willem Daendels, Pieter Vreede and Van Langen to guarantee "the unity and indivisibility" of the Batavian republic. The radical and omnipresent Fijnje represented the Uitvoerend Bewind and founded the "Binnenlandse Bataafse Courant" (Interior Batavian Courier). The controversial unitarissen did not long remain in power, for on 12 June 1798 general Daendels led another coup, this time putting the "moderates" in power in the Uitvoerend Bewind. For the corrupt former exiles with explicit opinions, whether democrat or aristocrat, there was no longer any place. Fijnje and Van Langen were locked up until the end of the year in the Gevangenpoort, accused of embezzling state money by the public prosecutor Van Maanen, but never put on trial.
