I did this in the following way :
Truth value can be determined means : if A always 1 then truth then truth value of A is 1. Or,if A ia always 0 then truth then truth value of A is 0.
From the question valid combinations of p and q are restricted to (0,1) , (1,0) and (1,1).
Based on that, Truth value of last column is not always 1 or always 0.
=> can not be determined.
