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: 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.

Input: Consider Input: Question: What is the official IAU name for the main star that is ioninizing  the surrounding material? Passage:Sharpless 264, also known as the Lambda Orionis Ring, is a molecular cloud and H II region, which can be seen in the northern region of the Orion Molecular Cloud Complex (OMCC), in the constellation of Orion. The OMCC is one of the best-known star formation regions and the closest sector of the Milky Way to our Solar System where high-mass stars are born. The nebula is named after its main star, λ Orionis, a blue giant responsible for the ionization of the surrounding material. It is also sometimes called the Angelfish Nebula due to its resemblance as to its lighter areas (pink to peach colour) to an angelfish. In the infrared its ionized boundaries are that which appears, instead.

Input: Consider Input: Question: Where was the surgeon and naturalist who described the Chaulmoogra odorata tree in 1815 educated? Passage:This paper caused some confusion. Mouat indicated that the oil was the product of a tree Chaulmoogra odorata, which had been described in 1815 by William Roxburgh, a surgeon and naturalist, while he was cataloging the plants in the East India Company’s botanical garden in Calcutta. This tree is also known as Gynocardia odorata. For the rest of the 19th century, this tree was thought to be the source of the oil. In 1901, Sir David Prain identified the chaulmoogra seeds of the Calcutta bazaar and of the Paris and London apothecaries as coming from Taraktogenos kurzii, which is found in Burma and Northeast India. The oil mentioned in the Ayurvedic texts was determined to be from the tree Hydnocarpus wightiana, known as Tuvakara in Sanskrit and chaulmugra in Hindi and Persian.
