Read the following passage and answer the questions:

"Described as charity hospitals established by the heads of the Vaishya families, Fa Hsien lists a cross-section of poor and maimed people who were examined and given medicines for cure at these hospitals. The stay of the patients and provisioning for medicine was available in-house. In effect, the description seems to physically testify the existing form of the ideal type of an Ayurveda hospital that Charak had mentioned in his treatise. Seen in conjunction with Emperor Asoka’s edicts informing us about planting of medical herbs which are suitable for men and animals and a number of passages from Sanskrit and Pali literature talking about the merits of establishing ‘Arogyashala’ (halls for health) and medical institutions, Charaka’s description of hospital does not seem to be historically untenable. They, in fact, lend a lot of credence to the Indic claim of being the place where institutional health care in South Asia evolved first."
