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.

Question: Question: Is Vitebsk the capital of a country? Passage:A.P. Rosengolts was born in Vitebsk on November 4, 1889. He was the son of a Jewish merchant. He joined the Bolshevik faction of the Russian Social-Democratic Workers' Party (RSDRP) in 1905, the year of the first, abortive Russian Revolution. He worked as an insurance agent and carried out work for the Bolshevik party in Vitebsk, Kiev, Ekaterinoslav and Moscow. Rosengolts played an active role in the Revolution of 1917. He was a member of the Executive Committee of the Moscow City Council, the Moscow Military-Revolutionary Committee and the All-Russian Military-Revolutionary Committee. He was a leading officer in the Red Army and, during the Russian Civil War, worked closely with L.D. Trotsky. After the Civil War, Rosengolts worked successively for the Commissariats of Transportation and Finance and the Directorate of the Red Army Air Force. He served as ambassador to Britain from 1925 to 1927 and oversaw Soviet espionage in Britain. He became a member of the Central Committee of the Communist Party of the Soviet Union in 1927 and held various high positions in the Communist Party and the Soviet government. In 1930 he was appointed People's Commissar of Foreign Trade. On June 14, 1937, Rosengolts was dismissed from this office and on October 7, 1937, he was arrested. He was one of the defendants of the third Moscow Trial, along with Nikolai Bukharin, Alexey Rykov and other prominent Soviet officials. The accused faced a long list of capital charges, including plotting to assassinate Lenin and Stalin, espionage and sabotage. Like most of his co-defendants, Rosengolts confessed. He was convicted, sentenced to death and shot on March 15, 1938 in Moscow. He was rehabilitated in 1988.

Question: 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.

Question: Question: How deep is the river SR 162 goes over? Passage:SR 162 was codified as SSH 5E during the creation of the primary and secondary state highways in 1937, beginning at Primary State Highway 5 (PSH 5) and U.S. Route 410 in Puyallup, traveling through Orting and South Prairie to end at an intersection with a branch of PSH 5 southwest of Buckley. SSH 5E had a branch that traveled south from Orting to Electron that was removed from the state highway system in 1955. The highway traveled across the Puyallup River into Orting on the McMillin Bridge, which opened in 1934 as a concrete half-through truss bridge to save the Department of Highways a total of $826. SR 165 was established during the 1964 highway renumbering and was codified in 1970 as the replacement to SSH 5E. The western terminus, now at SR 410, was moved east to an interchange in Sumner after the completion of the Sumner Freeway in 1972. The McMillin Bridge was added to the National Register of Historic Places in 1982 as an example of a half-through truss bridge built with concrete instead of steel. The route of the highway has not seen a major revision since 1972; however, WSDOT repaved the roadway and added guardrails between Orting and Buckley in 2008. The deteriorating McMillin Bridge is being replaced by WSDOT with a newer, wider span over the Puyallup River scheduled to begin construction in 2014.
