Answer: The young lady asked the mother why her daughter had not eaten anything.
Explanation:
When using indirect speech, the event in question is described as though someone else is reporting what happened without any quotes. This is in opposition to Direct speech where quotes are needed.
For instance: Jane asked Parrain, ''Are you answering questions on Brainly?''. This is direct speech. The indirect version would be: Jane asked Parrain if he/she was answering questions on Brainly.
The indirect version of the above would therefore be: ''The young lady asked the mother why her daughter had not eaten anything.''
