Car and Truck Expenses Worksheet "Was the vehicle available for personal use during off duty hours?"

Line 11 asks:  Do you have another vehicle available for personal use?  I answer:  YES

Line 12 asks:  Was THE (my emphasis) vehicle available for personal use during off duty hours?

Which vehicle is Line 12 referring to? 

Is the IRS intent on validating that ANOTHER vehicle is not just available, but more importantly, available during off duty hours?

Or... Is the IRS questioning if the actual BUSINESS vehicle is available for personal use during off duty hours?

Question 13 adds to the confusion, referring to "the vehicle".  Within this question, it appears evident that the inference is to the BUSINESS vehicle.  This is why I'm asking about Question 12's intent.
