Task: Question Generation
Input (English): Context: I recently flew UA to S. America , scrounging UA miles to upgrade to Business Class . After making the reservation , I put my US DM # into the reservation for credit ( I need credit to make Elite level ) . But when I got to the airport , UA had removed the US number and re - inserted the UA number , so I changed it and asked them to change it for the whole itinerary .
Output (English): Why did he enter the US number ?
