In this task, you're given a question, along with a context passage. The passage will not have a direct answer to the question, but can include some information and a clue for the answer. Assuming you can only obtain information about one entity in the passage, your job is to determine whether information from the passage can be used to answer the question. Indicate your choice as 'a' for Yes or 'b' for No.

[EX Q]: Question: How old was Georges Braque when he collaborated with Guardigli to create the famous long fish tank of the Fondation Maeght Passage:Guardigli was born in Ravenna. At 18 he enrolled in and attended the School of Fine Arts of Ravenna. During World War II he was drafted and served from 1943 until 1946 in the Regia Marina (Italian Royal Navy) at La Spezia). After the war he returned to the School of Fine Arts, receiving his diploma in 1948. He enrolled in the School of Painting and Mosaics, also in Ravenna, graduating in 1951. From 1951 to 1955 he worked with the Gruppo mosaicisti of Ravenna and restored many mosaics. Also in 1951, at the end of November, he arrived in Paris to teach at the Ecole d'Art Italien (School of Italian Art) as an assistant to the painter Gino Severini, founder and director of the school. Together with another mosaicist, his fellow Ravennan Lino Melano, he executed mosaic works for artists including Fernand Leger, Georges Braque, Marc Chagall, Jean Bazaine, and Raoul Ubac. He collaborated also on the mosaic for the facade of the Musee national Fernand Leger in Biot (Alpes-Maritimes). In 1960 he executed, at the Colombe d'Or of Saint-Paul-de-Vence, a mosaic by the painter Georges Braque. From 1961 he had a studio in the artists' residence La Ruche at 2, passage de Dantzing in Paris, the place described by Lorenzo Viani in the book Parigi 1925 (Paris 1925), published by Fratelli Treves. In 1962, in another collaboration with Braque, he created the famous long fish tank of the Fondation Maeght in St Paul de Vence. His collaborations with many illustrious artists continued; the last was Jean-Michel Folon. Many of his personal works in painting and mosaics are in prominent private and public collections. The latter portion of his life was spent in an old people's rest home in Paris, where he died in 2008.

[EX Q]: Question: What was the primary focus of the paper Royster had worked for before the war? Passage:After shakedown along the U.S. East Coast and in the Gulf of Mexico, Jack Miller sailed from Norfolk, Virginia, 13 June 1944, arriving Pearl Harbor 12 July via the Panama Canal Zone and San Diego, California. After more intensive training out of Pearl Harbor, she departed on 24 July screening a convoy to Eniwetok, where she arrived on 2 August. The remainder of the month was spent on patrol and convoy duty. Jack Miller sailed from Eniwetok on 2 September and, after escorting a convoy to Saipan, took up harbor patrol duty there. Antisubmarine patrols, convoy screening, and escort duty kept Jack Miller busy for the next nine months. During this period she sank five mines. In late 1944 Jack Miller came under the command of Lt. Commander Vermont C. Royster; he had served as the White House correspondent of The Wall Street Journal before the war. After the war ended, Lt. Commander Royster would leave the Navy and resume his journalism career at the Wall Street Journal; he would eventually become the paper's editor-in-chief in 1958.

[EX Q]: Question: Which Dynasty produced the most mathmaticians? Passage:Four outstanding mathematicians arose during the Song Dynasty and Yuan Dynasty, particularly in the twelfth and thirteenth centuries: Yang Hui, Qin Jiushao, Li Zhi (Li Ye), and Zhu Shijie. Yang Hui, Qin Jiushao, Zhu Shijie all used the Horner-Ruffini method six hundred years earlier to solve certain types of simultaneous equations, roots, quadratic, cubic, and quartic equations. Yang Hui was also the first person in history to discover and prove "Pascal's Triangle", along with its binomial proof (although the earliest mention of the Pascal's triangle in China exists before the eleventh century AD). Li Zhi on the other hand, investigated on a form of algebraic geometry based on tian yuan shu. His book; Ceyuan haijing revolutionized the idea of inscribing a circle into triangles, by turning this geometry problem by algebra instead of the traditional method of using Pythagorean theorem. Guo Shoujing of this era also worked on spherical trigonometry for precise astronomical calculations. At this point of mathematical history, a lot of modern western mathematics were already discovered by Chinese mathematicians. Things grew quiet for a time until the thirteenth century Renaissance of Chinese math. This saw Chinese mathematicians solving equations with methods Europe would not know until the eighteenth century. The high point of this era came with Zhu Shijie's two books Suanxue qimeng and the Siyuan yujian. In one case he reportedly gave a method equivalent to Gauss's pivotal condensation.
