Many of the correct answers you give do not have the " " wrapping around the text arguments in the expressions. Is there a statement I missed somewhere that says that we should assume there are quotes wrapping the text arguments?
For Question one, in order to get the same value of the number of days option number two needs to have ABS (absolute value) as the calculation Days(A2,A1) in your example give a negative number where as A2-A1 gives a positive number. So, only answer number 1 is the only accurate answer based upon the cell references in your formulas.
