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 is the scientific name for studying why there are foreign materials in a bee's honey? Passage:Anemophilous pollen grains are light and non-sticky, so that they can be transported by air currents. They are typically in diameter, although the pollen grains of Pinus species can be much larger and much less dense. Anemophilous plants possess well-exposed stamens so that the pollens are exposed to wind currents and also have large and feathery stigma to easily trap airborne pollen grains. Pollen from anemophilous plants tends to be smaller and lighter than pollen from entomophilous ones, with very low nutritional value to insects. However, insects sometimes gather pollen from staminate anemophilous flowers at times when higher-protein pollens from entomophilous flowers are scarce. Anemophilous pollens may also be inadvertently captured by bees' electrostatic field. This may explain why, though bees are not observed to visit ragweed flowers, its pollen is often found in honey made during the ragweed floral bloom. Other flowers that are generally anemophilous are observed to be actively worked by bees, with solitary bees often visiting grass flowers, and the larger honeybees and bumblebees frequently gathering pollen from corn tassels and other grains.

Example Input: Question: Which Super Kings player who were ahead of Badree in team depth is the oldest? Passage:Badree first played for an overseas Twenty20 franchise in January 2013, when he played for the Khulna Royal Bengals in the 2013 Bangladesh Premier League (BPL) season. Later in the year, he signed with the Rajasthan Royals for the 2013 Indian Premier League (IPL), although he played only a single game (against the Delhi Daredevils). In the 2014 IPL auction, Badree was bought by the Chennai Super Kings for US$50,000. He went on to play four matches for the team during the 2014 season, but took only two wickets, with Ravichandran Ashwin and Ravi Jadeja being the preferred spin options. Later in 2014, Badree signed with the Brisbane Heat for the 2014–15 Big Bash League season in Australia. He was unable to play any matches due to a shoulder injury, but re-signed for the 2015–16 season. He struggled for form early in the season, going wicketless in his first three games, but eventually bounced back to finish as his team's leading wicket-taker, with nine wickets from eight matches. This included 5/22 in the final game of the season, against the Melbourne Stars.

Example Output: b

Example Input: Question: Did other indigenous tribes also speak the Yugambeh language? Passage:Archaeological evidence suggests Indigenous Australians inhabited the area for more than ten thousand years before European settlement. The Indigenous tribe that lived in the area were known as the Kombumerri people and spoke the Yugambeh language. The Kombumerri people named the area Goo-een. In 1869, Richard Gardiner became the first European to settle in the area, which was known as Nerang Creek Heads at the time. Gardiner built a house and wharf on the river end of Queen Street which later led to the Loder family and several others following his lead and building in the area. The settlement was surveyed in 1874 and the area was renamed Southport because it was the southernmost port of the colony of Queensland and took inspiration from the English seaside town. In 1877 German immigrant Johan Meyer acquired James Beattie's land at Narrow Neck and started a private ferry service that transported Southport residents to the beachside area that was named Elston shortly after. Meyer's Ferry operated just south of Queen Street on Meyer's Ferry Road and would take travelers across the Nerang River to Elston's Meyer's Ferry Road. In 1878 Richard Gardner opened the Southport Hotel, the town's first pub.
