Task: Wrong Candidate Generation
Input (English): Context: Besides , getting it out of the way now leaves us feeling more secure and allows us to focus on other expenses . As seen in my earlier entries , last winter was survived rather comfortably on less than 100 gallons of fuel oil , supplemented with occasional uses of a small electric space heater . So , with 100 gallons being the minimum purchase for delivery , we bought just that again this year . 
Question: What may have happened that winter with only 100 gallons of fuel oil ? 
Correct Answer: This may not have been sufficient and they ran out .
Output (English): They asked for advice on what else they can be using for heat .
