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.

Example Input: Question: What other advertisements did Microsoft release the year it launched The Life? Passage:The Life, also known as We Are ODST is a television and cinema advertisement launched in 2009 by Microsoft to promote the first person shooter in the United States. The 150-second piece follows a young soldier through enlistment, training, and battle as an Orbital Drop Shock Trooper (ODST), analogous to a paratrooper that drops from space to a battlefield. The Life was created by advertising agency T.A.G., an offshoot of McCann Erickson. Production of the commercial itself was handled by production company Morton/Jankel/Zander (MJZ). It was directed by Rupert Sanders, and post-production was conducted by Asylum. It was filmed in Hungary, just outside Budapest in a coal mine and abandoned factories to give the sequence an "Eastern Bloc" aesthetic. The commercial and its associated campaign proved hugely successful; on the week of its launch, Halo 3: ODST became the top-selling game for the Xbox 360 worldwide, and over 2.5 million copies were sold within the first few weeks of release. The Life went on to win a number of honours from the advertising and entertainment industries, including two Clio Awards, a London International Advertising Award and several honours from the Cannes Lions International Advertising Festival, the most prestigious awards ceremony in the advertising industry.

Example Input: 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 45nm 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 22nm lithography.

Example Input: Question: Which king who made a deal to remove Roussel was born first? Passage:He was present at the Battle of Manzikert in 1071, where he refused to join the fray; the battle proved to be a disastrous defeat for the Byzantines. Despite this treachery, he was kept in imperial service, where good generals were needed, and was sent into Asia Minor again with a force of 3,000 Franco-Norman heavy cavalry. There Roussel conquered some territory in Galatia and declared it an independent state in 1073, with himself as prince, following the example set by his fellow Normans in the Mezzogiorno. His capital was Ankara, now the capital of Turkey. He defeated the Caesar John Ducas and sacked Chrysopolis, near Constantinople. He even supported a usurper candidate, but by formally ceding lands that the Seljuk Turks had actually conquered, the emperor Michael VII persuaded the Seljuk warlord Tutush I to remove Roussel. However both Ducas and Roussel were defeated and captured by Turkish forces, fortunately for Roussel his wife was able to pay the ransom demanded by the Turks allowing Roussel to return to Amasea, where the population so loved him that he made himself undisputed governor. He was given up by the people through a ploy of Alexius Comnenus (1074), then a general, later an emperor.
