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 city had a greater population the year Gordon led his regiment to the Battle of Marks' Mills, Little Rock or Camden? Passage:In March and April 1864, Shelby's men harassed and skirmished with the Union Army force under the command of Major General Frederick Steele during his Camden Expedition, part of the Red River Campaign. Gordon led more than one charge against the Union forces during Steele's march from Little Rock to Camden, Arkansas. On April 25, 1864, Gordon led his regiment at the Battle of Marks' Mills where they captured two Union artillery pieces from the detachment of Union Lieutenant Colonel Francis M. Drake when Shelby's force attacked the Union left wing of the detachment which had been sent from Camden toward Pine Bluff, Arkansas to obtained supplies for Steele's force which was increasingly besieged by gathering Confederate forces at Camden. The Confederates outnumbered the Union force at Marks' Mills by more than 2 to 1 and overwhelmed it, taking about 1,300 prisoners and about 240 wagons. The overall commander of the Confederate cavalry force at Marks' Mills, Brigadier General James Fagan, led the Confederates, including Shelby's command, toward Pine Bluff in an effort to capture the Union supply depot. The Confederates did not make it to Pine Bluff due to flooding. They also did not return fast enough to cut off Steele's return march to Little Rock or to participate in the Battle of Jenkins' Ferry, the one big engagement during the retreat before the Union troops escaped across the swollen Saline River.
