Task: Question Answering
Input (English): Context: I talked to my landlord and she said they 'd been living there since September 1st and just had n't gotten around to notifying me yet . She said there was n't much of the deposit left because she used it for all of August AND for advertising ( Pennysaver , Craigslist , things like that ) . Then she said that she had 21 days to give me the remainder back after I gave her the keys . 
Question: What was the reason for the ads ?
Output (English): She needed to find another tenant .
