In this task, you are given a question and a context passage. You have to answer the question based on the given passage.

Example Input: How does a chestnut tree form its heartwood?, Context: The term heartwood derives solely from its position and not from any vital importance to the tree. This is evidenced by the fact that a tree can thrive with its heart completely decayed. Some species begin to form heartwood very early in life, so having only a thin layer of live sapwood, while in others the change comes slowly. Thin sapwood is characteristic of such species as chestnut, black locust, mulberry, osage-orange, and sassafras, while in maple, ash, hickory, hackberry, beech, and pine, thick sapwood is the rule. Others never form heartwood.
Example Output: the change comes slowly

Example Input: Where is the Kathmandu Art Centre located?, Context: Kathmandu is a center for art in Nepal, displaying the work of contemporary artists in the country and also collections of historical artists. Patan in particular is an ancient city noted for its fine arts and crafts. Art in Kathmandu is vibrant, demonstrating a fusion of traditionalism and modern art, derived from a great number of national, Asian, and global influences. Nepali art is commonly divided into two areas: the idealistic traditional painting known as Paubhas in Nepal and perhaps more commonly known as Thangkas in Tibet, closely linked to the country's religious history and on the other hand the contemporary western-style painting, including nature-based compositions or abstract artwork based on Tantric elements and social themes of which painters in Nepal are well noted for. Internationally, the British-based charity, the Kathmandu Contemporary Art Centre is involved with promoting arts in Kathmandu.
