The management is not supposed to call someone after a house has been rented out to inform them, so receiving a call from them would imply that the person was not chosen for the house and hence they should not be ecstatic about it.
Consider the staetement "The day before I was supposed to see a house I wanted to rent the property management called to say the owners had already rented it out.". Based on this statement, is "I was ecstatic when the management called to say that the house I wanted to rent had already been rented out." a true statement? Yes/no/unknown
