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.

[Q]: Question: When was the firm that designed the Oregon library established? Passage:The Oregon Library was designed by Chicago architects Pond and Pond. The Ponds were members of the Eagle's Nest Art Colony, founded by Lorado Taft, and their association with Taft and the colony led them to design the library. Their design was influenced by the colony, and a combination of two architectural styles, Classical Revival and the Arts and Crafts movement. The completed library included a second floor art gallery to which members of Eagle's Nest donated works for a permanent collection. The gallery's collection includes 64 paintings and sculptures as well as a Currier and Ives lithograph collection appraised at US$700,000. The Oregon Public Library was listed on the U.S. National Register of Historic Places in 2003, three years later it was included as a contributing property in a historic district that received the National Register designation.

[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.

[Q]: Question: How many athletes competed in the 1952 Winter Olympics? Passage:A legal purge took place in Norway after WWII in which 53,000 people were sentenced for treason and 25 were executed. The post-war years saw an increased interest in Scandinavism, resulting in Scandinavian Airlines System in 1946, the Nordic Council in 1952 and the Nordic Passport Union along with the metric system being introduced. Reconstruction after the war gave Norway the highest economic growth in Europe until 1950, partly created through rationing private consumption allowing for higher industrial investments. The Labor Party retained power throughout the period and maintained a policy of public planning. The University of Bergen was created in 1946. The 1950s saw a boom in construction of hydroelectricity and the state built the steel mill Norsk Jernverk and two aluminum works. State banks such as the State Housing Bank, the State Educational Loan Fund and Postbanken allowed for governmental control over private debt. Oslo hosted the 1952 Winter Olympics.
