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.

Input: Consider Input: Question: When was the star in Draco that is visible primarily in the northern hemisphere discovered? Passage:Like the star Epsilon Draconis in the constellation of Draco, Beta Cephei is visible primarily in the northern hemisphere, given its extreme northern declination of 70 degrees and 34 minutes. It is nevertheless visible to most observers throughout the world reaching as far south as cities like Harare in Zimbabwe, Santa Cruz de la Sierra in Bolivia or other settlements north 19South latitude. It is circumpolar throughout all of Europe, northern Asia, and North American cities as far south as Guadalajara in west central Mexico. All other locations around the globe having a latitude greater than 20North will notice that the star is always visible in the night sky. Because Beta Cephei is a faint third magnitude star, it may be difficult to identify in most light polluted cities, though in rural locations the star should be easily observable.

Input: Consider Input: Question: What were the differences between the Good Parliament and the Bad Parliament? Passage:Owing to Gaunt's influence, he was chosen in January 1376/7, in the last of Edward III's parliaments (the Bad Parliament), to act as Speaker of the House of Commons. According to the Rolls of Parliament (ii. 374) Hungerford "avait les paroles pur les communes d'Angleterre en cet parliament" ('[he] spoke for the commons of England in said Parliament'). He is thus the first person formally mentioned in the Rolls of Parliament as holding the office of speaker. Sir Peter de la Mare preceded him in the post, without the title, in the Good Parliament of 1376. In 1380 Hungerford was appointed Forester of Selwood. In 1369 he purchased from Walter Pavely, de jure Baron Burghersh, the manor of Farleigh Montfort, now called Farleigh Hungerford, which served as the chief residence of his descendants, and in 1383 obtained licence to crenellate his manor house there, which thus became Farleigh Castle. In about 1384 he aroused the suspicion of King Richard II, who attached him, but he obtained a pardon and also a confirmation of his free warren at Farleigh.

Input: Consider Input: Question: Were the Bosporans enslaved by the Romans? Passage:According to the Georgian chronicles, Nana was "from a Greek territory, from Pontus, the daughter of Oligotos" whom Mirian married after his first wife died (in 292 according to Cyril Toumanoff). Nana bore Mirian two sons: Rev II, Varaz-Bakur and a daughter who married Peroz, the first Mihranid dynast of Gugark. Pontus here may refer to the Bosporan Kingdom, then a client state of the Roman Empire. Toumanoff has assumed that the name of Nana's father might have been a Georgian corruption of "Olympius" or "Olympus", a Bosporan dynast whose son Aurelius Valerius Sogus Olympianus, a Roman governor of Theodosia, is known from a Greek inscription of 306 dedicated to "the Most High God" on the occasion of the building of the Jewish "prayer house". Alternatively, Christian Settipani identifies Nana as a younger daughter of Theothorses, a Bosporan king.
