Task: Question Answering
Input (English): Passage: The Reed Dance today is not an ancient ceremony but a development of the old "umchwasho" custom. In "umchwasho", all young girls were placed in a female age-regiment. If any girl became pregnant outside of marriage, her family paid a fine of one cow to the local chief. After a number of years, when the girls had reached a marriageable age, they would perform labour service for the Queen Mother, ending with dancing and feasting. The country was under the chastity rite of "umchwasho" until 19 August 2005. Question: Until what date was Swaziland bound by umchwasho?
Output (English): 19 August 2005
