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: What was the lithography previous to 45 nm? Passage:The Intel Core microarchitecture (previously known as the Next-Generation Micro-Architecture) is a multi-core processor microarchitecture unveiled by Intel in Q1 2006. It is based on the Yonah processor design and can be considered an iteration of the P6 microarchitecture introduced in 1995 with Pentium Pro. High power consumption and heat intensity, the resulting inability to effectively increase clock speed, and other shortcomings such as an inefficient pipeline were the primary reasons why Intel abandoned the NetBurst microarchitecture and switched to a completely different architectural design, delivering high efficiency through a small pipeline rather than high clock speeds. The Core microarchitecture initially did not reached the clock speeds of the NetBurst microarchitecture, even after moving to 45 nm lithography. However after many generations of successor microarchitectures which used Core as their basis (such as Nehalem, Sandy Bridge and more), Intel managed to eventually surpass the clock speeds of Netburst with the Devil's Canyon (Improved version of Haswell) microarchitecture reaching a base frequency of 4 GHz and a maximum tested frequency of 4.4 GHz using 22 nm lithography.

[EX Q]: Question: How many years did the war where Lyon served with the 2nd Battalion last? Passage:Lyon was commissioned as a Second Lieutenant into the 4th (Extra Reserve) Battalion, the North Staffordshire Regiment in February 1900, but two months later, in April of the same year, transferred to the 2nd Battalion of the regiment. The 2nd Battalion was a regular battalion and was at the time on active service in South Africa during the Second Boer War, where Lyon joined the battalion and served with it throughout the war being Mentioned in Despatches in 1901. He was promoted to lieutenant on 19 January 1901, while in South Africa. After peace was declared in May 1902, Lyon left Cape Town on board the SS Bavarian and arrived in the United Kingdom the following month. He remained with the 2nd Battalion when it was posted to India in 1903 where he became adjutant and was promoted to captain.

[EX Q]: Question: In what present day country did the Bagttle of Deols occur? Passage:About 460, Roman diplomat and bishop Sidonius Apollinaris sent a letter to Riothamus asking his help to quell unrest among the Brettones, British colonists living in Armorica; this letter still survives. In the year 470, Western Emperor Anthemius began a campaign against Euric, king of the Visigoths who were campaigning outside their territory in Gaul. Anthemius requested help from Riothamus, and Jordanes writes that he crossed the ocean into Gaul with 12,000 soldiers. The location of Riothamus' army was betrayed to the Visigoths by Arvandus, the jealous praetorian prefect of Gaul, and Euric defeated him in the Battle of Déols after Riothamus army was driven from Avaricum (Bourges) where he had been welcomed by the Bituriges before the fight. Riothamus was last seen retreating northward to Burgundy when Euric besieged Arvernum (Clermont-Ferrand) just south of the Bituriges territory.
