I want to know the answer to the following question:
What fraction of Kathmandu's population died in an ancient earthquake?
All the background I'm provided with is that "These disasters led to the destruction of most of the architecture of the Licchavi era (such as Mangriha and Kailashkut Bhawan), and the loss of literature collected in various monasteries within the city.". Is that enough to answer the question?
Answer: no
