Reverse 1031 Exchange - Question 3 on form 8824: Date you actually transferred your property to the other party?

I transferred the title of the relinquished property to the EAT so that I can close the escrow of the replacement property. 

How do I answer question #3 on form 8824? Is it the date I transferred the title of the relinquished property to the EAT? Or the closing date to the new buyer?

Thanks
